Definitions
- the present invention relates to an umbilical syringe and a blood sampling syringe, and more particularly to a syringe having a bellows-shaped cylinder body.
- the conventional syringe 21 generally has a structure as shown in FIG. 7, in which a piston 23 is inserted into a cylinder 200 and a needle portion 24 is inserted into a tip thereof.
- the sealing solution is pierced with a syringe needle to suck up the drug solution therein.
- the conventional syringe cannot be made smaller than the length of the needle part X + the length of the cylinder one and the length of the piston tail part Y as shown in FIG. It was bulky for disposal.
- the inventor managed to replace the conventional combination of amble + non-shortening syringe with a single syringe, and made repeated experiments to achieve a syringe that takes up less space for disposal, and as a result, completed the present invention.
- the present invention relates to an umbilical syringe and a bellows-shaped cylinder, which integrally have a bellows-shaped extruder in a bellows-shaped cylinder capable of enclosing a chemical solution, a bellows-shaped cylinder, a holding tool for holding a bellows in a contracted state, and a blood sampling device having a handle for extending the bellows.
- the bellows-shaped portion is longitudinally folded at several places in order to smoothly expand and contract the bellows-shaped cylindrical portion.
- the biggest feature is the provision of a capturing part.
- both syringes have been devised to keep the bellows-shaped tubular part in a compressed state.
- the syringe is provided with front and rear wings, and a bellows-contracted holding fixture is provided so that one can be locked to the other.
- the rain syringe has a conical tip, a piston provided with a finger pressing portion 9 (recess for depression) at the rear of the piston, and a needle that can be fitted to the tip of the cylinder body.
- the gist of the combined use of the ambler and the syringe is that a projection is provided inside the injection needle to break the sealed seal of the sealed content liquid.
- the ampoule-syringe of the present invention can be used also during infusion.
- the rear wing provided at the rear of the piston can be used as a handle for extending the bellows.
- FIG. 1 shows a first embodiment of the present invention.
- FIG. 1 (a) is a front view of an amble / syringe barrel.
- (B) is a right side view.

- a chemical-resistant plastic such as a fluororesin, an isophthalic acid-based unsaturated polyester resin, a vinyl ester resin, an epoxy resin, and a furan resin is preferable. Care must be taken with regard to the corrosion resistance of the resin, because the curing agent has a significant effect.
- a hypodermic injection type if the needle is sharp at both ends so that the enclosed liquid sealing membrane can be penetrated, or if only one end is sharp, the needle is as shown in 16 in FIG. It is necessary to provide internal projections for breaking the sealing film.
- a needle having only a sharp tip may be used.
- a fold 15 in the bellows bellows portion for capturing a few places as shown in FIG. 3, since this portion acts as a guide for the pressing force.
- the folds are formed by increasing the thickness of the bellows peaks and valleys outward as shown in Fig. 3.
- the method of connecting the syringe body and the injection needle part is almost the same diameter, that is, the tip of the body part is formed slightly smaller than the diameter of the injection needle part, and may be simply fitted together. May be combined.
- the tip of the syringe body may be formed so that it can be screwed into the three-way cock.
- Seal membranes 10 and 10 ′ for sealing the enclosed chemical solution are provided inside the tip of the syringe body that also serves as an amble. The position of the sealing film may be 10 or 10 'depending on the situation. At the rear of the piston, there is a depression for applying pressure.
- the projections 7 provided on the rear wings 6a and 6b can be fitted into the fitting holes (:, D) of the front wings 5a and 51 so that they can be fixed compactly at the time of disposal.
- the protrusions are provided with fibrous heads 7A and 7B at the tips of the projections so that they do not come off after fitting.
- FIG. 1 (a) is a front view of the body 1 and (b) is a right side view.
- 2 is a bellows-shaped tube, 3 is a tip, 4 is a threaded part, 5a and 5b are front blades, 6a and 6b are rear blades, 7 is a protrusion, 8 is a piston, 9 is a finger press, 10 is a seal film.
- FIG. 2 is a front view of the injection needle, wherein 11 is a double-pointed needle, 12 is a cap, and 13 is a threaded portion inside the cap.
- the body 1 is made of a chemical-resistant plastic (polypropylene) and integrally forms a front end 3 with a bellows-like cylindrical portion 2 and a rear pressing portion 14 having a piston 8.
- a chemical-resistant plastic polypropylene
- the leading and trailing portions have blades 5a, 5b, 6a and 6b, respectively, and the rear blades 6a and 6b are provided with protrusions.
- This projection has conical heads 7A and 7B at the columnar shaft portion and at the tip, the diameter of the bottom circle of which is larger than that of the shaft portion.
- the front blades 5a and 5b have fitting holes ⁇ and D having the same large diameter as the projection axis to correspond to the projections. These are described as bellows-contracted state holding fasteners, but this method is not limited to this as long as it can perform the same function, and it goes without saying that any configuration may be used.
- the bellows is in a stretched state because the drug solution is filled, and the protrusions are not fitted in the fitting holes of the front wing and D, but the drug solution is injected. Later, when discarding, as shown in FIG. Since the conical heads 7A and 7B at the tip of the projection are conical, once fitted, they will not come out of the hole. Since the syringe according to the present invention can be disposed in such a compact shape after use, it is convenient and has no danger.
- the seal film 10 is provided at the forefront of the threaded portion 4, but it is needless to say that the seal film 10 may be provided on the inner side like 10 '.
- Example 2 In the longitudinal direction of the bellows-shaped body in Example 1, four folds 15 for capturing as shown in FIG. 3 were provided, the material was changed to fluororesin, the injection needle was sharpened only at the tip, and the injection needle was placed inside the injection needle.
- a syringe was manufactured in the same manner as in Example 1 except that the internal projection 6 (FIG. 4) was provided.
- the number of the reinforcing folds may be any number, but 2 to 6 is considered appropriate.
- the sealing film for sealing the chemical solution is broken by the convex inner projection 6 as in the present embodiment, the sealing film is ruptured firmly and largely, and a small piece of the sealing film is formed by the injection needle as compared with a case where the sealing film is pierced at the tip of the needle. This is convenient because there is no danger of blocking the hole inside.
- Example 3
- the material of the ampoule / syringe in Example 2 was changed to isophtalic acid-based unsaturated polyester resin, the injection needle was sharpened only at the tip, and an internal projection 17 (Fig. 9) was provided inside the injection needle part.
- the tip of the syringe body is formed so that it can be screwed into the stopcock 18.
- the sealing needle 10 is broken by screwing the injection needle portion 19 of the amble dual-purpose syringe to the torso tip 20.
- the injection needle part 19 is removed again, and the torso tip 20 is screwed into the three-way cock 18 this time. In this way, it is possible to add a chemical solution to the drip.
- a protrusion 21 for breaking the sealing seal 10 may be provided.
- the ampoule / syringe of the present invention is designed so that the diameter ⁇ shape of the tip of the barrel of the syringe can be made to correspond to, for example, the device of the other party in various use forms and in use. This will enable widespread use in all areas of medicine.
- Example 4
- this embodiment shows a syringe for collecting blood.
- the needle is one-sided and the inside is initially a space without filling with a drug solution, and thus has no seal film.
- the bellows is initially in a contracted state, and when collecting blood without taking up space, pull the biston with the rear wing 6a as a handle for extending the bellows in the direction of the arrow in Fig. 5. This causes the blood collection to accumulate in the bellows cylinder.
- the connection between the injection needle portion and the body portion is not screwed, and a simple fitting cap may be used.
- the body 1 and the rear pressing portion 14 having a piston may be formed integrally or may be fitted. However, it is preferable to form the body integrally because it is necessary to maintain the sealing of the drug solution and blood collection.
- the operation of sucking the medicinal solution from the medicinal amble into the syringe for subcutaneous, sarcastic, intramuscular, spraying, or intravenous injections This eliminates the necessity of cutting the amble neck and disposing of the sample, so that injections can be handled immediately on site. Therefore, 100% of accidental cuts at ampoule cuts can be prevented.
- the shape of the syringe before use is also compact, which is also convenient.
- the bellows can be made compact by shrinking the bellows, and the disposal is convenient.
