Abstract

The utility model discloses a back cover device for a syringe needle cap of an oral cavity department, which comprises a clamp holder, a handle and a base. The handle is clamped by hands, and the clamp holder can be opened; the gripper can be closed by releasing the handle. The gripper clamps the needle cap with common diameter through free opening and closing; the rubber pad on the inner side can further ensure the retention effect of the needle cap. The base ensures that the whole device is stably placed on the table-board. The back sleeving can realize two functions of removing the needle cap by one hand and accurately sleeving the needle cap back, and can clamp the syringe needle caps with various diameters; the structure is simple, and the cleaning and the disinfection are facilitated; avoid the sharp device of the medical staff to stab.

Description

Syringe needle cap back-cover device for stomatology department

Technical Field

The utility model relates to a back cover device of a syringe needle cap for stomatology department, which belongs to the technical field of medical instruments.

Background

Sharp-ware puncture is one of the main ways of causing occupational infection and blood-borne diseases of medical personnel in stomatology, and the back-set needle cap is a high-risk operation causing the sharp-ware puncture. According to the occupational exposure protection standard, a single-hand back-sleeve needle cap is required to prevent needle stick injury. However, in the actual clinical diagnosis and treatment process of the department of stomatology, the traditional method of sleeving the syringe needle cap back by one hand has some disadvantages: 1, the needle cap has a small inlet and is not fixed, so that the needle cap cannot be successfully sleeved once, and time is wasted; or the needle head is easy to contact a non-clean area in the process of back sleeving, so that the needle head is polluted; 2, the needle cap is sleeved with a needle by one hand, but the needle is pulled out of the needle cap by two hands, so that the risk of needle stick injury is increased. The prior art needle cap holder usually has a circular base which is placed on the instrument table with the needle cap holder inlet perpendicular to the base and the needle cap insertable into the holder inlet. However, such a fastener has some disadvantages: 1, the inlet of the fixer has a fixed diameter and is difficult to adapt to needle caps with different diameters, if the diameter of the inlet of the fixer is obviously larger than that of the needle cap, the needle cap is difficult to fix, and if the diameter of the inlet of the fixer is obviously smaller than that of the needle cap, the needle cap is difficult to insert or take out after being inserted; 2 the inlet of the fixer is small and deep, which is not beneficial to cleaning and disinfection. Therefore, medical care personnel need a needle cap returning device with reasonable design and simple structure in the department of stomatology to solve the problems.

Disclosure of Invention

In order to overcome the problem that current oral cavity local anesthesia syringe can't once only overlap successfully, need both hands just can extract the syringe needle from the needle cap when overlapping the needle cap again, also need not match, be unfavorable for cleanness and disinfection scheduling problem with the needle cap diameter in order to solve current fixer entry diameter, the utility model provides a but open needle cap overlap device of multiple diameter needle cap of centre gripping, structure to realize that the one hand gets rid of and accurate overlap two kinds of functions of needle cap and convenient cleanness and disinfection.

The utility model provides a technical scheme that its technical problem adopted is: the needle cap returning device is made of stainless steel materials and comprises a clamp holder, a handle and a base. A layer of rubber pad is arranged on the inner side of the clamp holder, and the diameter of the opening is 0.5 cm; the holder and the handle are connected with each other through a connecting joint and an elastic steel wire, and the base is fixed on the connecting joint through a screw. The handle is clamped by hands, and the clamp holder can be opened; the gripper can be closed by releasing the handle. The gripper clamps the needle cap with common diameter through free opening and closing; the rubber pad on the inner side can further ensure the retention effect of the needle cap. The base ensures that the whole device is stably placed on the table top

The utility model has the advantages that: the utility model fixes the needle cap by the free open and close of the clamper, thereby realizing the function of removing and accurately returning the needle cap with various diameters by one hand; simple structure, open structure, no sanitary dead angle, and is beneficial to cleaning and disinfection.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a top view of the present invention

FIG. 2 is a side view of the present invention

In the figure, 1 clamp holder, 2 rubber pads, 3 connecting joints, 4 bases, 5 handles, 6 elastic steel wires and 7 screws

Detailed Description

[ example 1 ]:

the needle cap returning device is placed on an operation table top through a base 4, a handle 5 is pressed by hands, and a clamp holder 1 can be opened through an elastic steel wire 6 and a connecting joint 3; the injector with the needle cap is placed between the rubber pads 2 on the inner side of the clamper 1 upside down, the handle 5 is loosened, the clamper 1 is closed, and the needle cap is fixed between the rubber pads 2.

[ example 2 ]:

when the needle head needs to be pulled out from the needle cap, the needle head is directly pulled out by a single hand vertical operation table surface, and the needle cap can be remained between the rubber pads 2.

[ example ] 3:

when the needle head needs to be sleeved back into the needle cap, the needle head of the syringe is directly inserted into the needle cap fixed between the rubber sheets 2 by a single hand, and then the needle head can be sleeved back into the needle cap.
