LANCET.

Specification of Letters Patent.

Patented Apr. 13, 1915..

Application filed July 1, 1814. Serial No. 848,413.

To all whom it may concern:

Be it known that 1, WILLIAM M. PoLLooK, -a citizen of the United States, residing at Forest Grove, in the county of Washington and State of Oregon, have invented certain'new and useful Improvementsin Lancets, of which the following is a specificatlon.

This invention comprehends certain new and useful improvements in lancets and has for its primary object to provide a surgical instrument of this character which will be of improved construction and operation as well as highly efficient in use and which will be formed in such manner that a guide may be readily positioned upon the tapered end of the plunger casing to locate the lancet opposite the part to be lanced and retain the lancet point in proper position during operation of the device.

Another object of this invention is to provide a device of this character in which the movement of the plunger by which the lancet point is carried, may be readily regulated and will be automatically returned to normal position.

A further object 'of' the invention is to provide an improved form of lancet with which a guide and tongue depressor may be readily engaged, as desired.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of the complete device, Fig. 2 is a longitudinal'section through the same, Fig. 3 is an enlarged perna ppective view of the guide removed, Fig. 4

airs an end elevation of a modified form of guide, and Fig 5' is a detail view of the tongue depressor attachment removed. Referring in detail to the drawings by numerals, 1 designates the barrel having a tapered forward end 2 and an inwardly directed guide collar 3 adjacent its forward end to serve as a guide for the plunger 4 engaged thrpugh thesame and having the lancet point 5 removably secured to its forward end by means a threaded shank 6 carried by said lancet point 5 and threaded in the socket 7 in the forward end of said plunger 4.

lit will be readily understood that the lan set point 5 is within the'forward end of the barrel 1 when the plunger 4 is in its innermost or normal position and when said plunger 4 is forced forwardly against the tension of the spring 8, said spring 8 is compressed and the lancet point 5. is forced out of theforward end of the barrel 1 and through the ing operation of the device, and it will be readily seen that this guide will be extremely light and yet strong and durable as well as sanitary, as said guide may be readily removed, cleansed and sterilized, as desired. i

It will be readily understood that the spring 8 is positioned around the plunger 4 and within the barrel 1 and has one end bearing against the guide collar 3, while its opposite end bears against the stop collar 13 formed around the plunger 4 and adapted, when the plunger 4 is in its innermost or. normal position, for engagement with the central portion 14 of the cap 15 threaded upon the rear end of the barrel 1, as shown at 16, and provided with radially directed arms 17 by means of which the cap 15 may be readily rotated and it will be understood that the cap .15 is secured upon the barrel 1 after the plunger 4 and spring 8 have been placed in said barrel. It will also be understood that the cap 15 has a suitable central opening 18 through which the-threaded portion 19 of the plunger 4 is adapted to move freely during operation of the device,

an adjustable movement limiting or regu- "lating collar 20 is. threaded 'upon the threaded portion 19 of the plunger 4 and adapted to be moved longitudinally thereof by rotating said collar in the proper direction upon said plunger, to regulate the'd'istance the plunger 4 is to move-forwardly, it being understood that the collar 20 may headas, i

justed for each operationof the device, as desired. It will also be seen, by referring to the drawings, that I have provided a plunger head 21 from the free rear extremity of the plunger 4 and having a concave face 22 to receive the thumb of the operator and prevent the thumb from slipping off the head during operation of the device. When it isdesired to use the lancetin performing operations in the mouth or throat, a longitudinally curved spring tongue depressor 23 may be employed and secured upon the barrel 1 by means of the transversely split clamp ring 24 mounted upon the inner end of said spring tongue depressor 23 and adapted for clamping engagement around the barrel 1. It will be understood that the spring tongue depressor 23 is preferably formed of a strip of spring metal and having oppositely directed side arms ,WlllCh are curved outwardly and then brought inwardly to form the transversely slit spring clamping ring 23 and it will be readily seen that this ring 23 may be adjusted longitudinally upon the barrel 1, as de sired.

In Fig. 4 I have shown a modified form of guide in which the outer edge 11 is of oval form and it will be readily understood that the outer edge of the guide in each form is preferably roughened to prevent movement oft-he same upon the flesh with which it is engaged. In the modified form of guide, however, the inner portion 10 and connect-' ing'arms 12 are of substantially the same construction as the preferred-form.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in the details of construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed, or sacrificing any of the advantages thereof.

What is claimed is 1. The combination with a lance and taper end thereof, of a removable guide comprising a circular end, metallic legs secured to the outer extremities of said guide, and curved to conform to the tapered end of the lance.

2. The combination with a lance and taper end thereof, of a removable guide comprising a substantially circular end, upper surface of said guide roughened to engage with the flesh and preventmovement of the same, resilient legs secured to the outer edges of said guide and bent to conform with the tapered'end of the lance.

3. The combination with a lance and tapered end thereof, of a removable guide comprising a circular end having its upper surface roughened to prevent slipping upon the flesh when engaging the same, metallic legs secured to said guide at its outer extremities, said legs bent to it the tapered end of said lance and hold the guide against further movement upon said lance.

In testimony whereof I ai'iix my signature in presence of two witnesses.
