Description

Dental syringe needle cap return device

technical field

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

Background technique

Sharps stabbing is one of the main ways to cause occupational infection of blood-borne diseases among dental medical staff, and the trocar cap is a high-risk operation that leads to sharps injuries. One-handed needle caps should be used to prevent needlestick injuries according to occupational exposure protection standards. However, in the actual clinical diagnosis and treatment process of stomatology, the traditional method of re-inserting the needle cap of the syringe with one hand has some drawbacks: 1. The entrance of the needle cap is small and not fixed, which may not be able to be successfully re-inserted at one time, which is a waste of time; or the needle is being re-inserted. During the process, it is easy to touch the non-clean area, causing needle contamination; the 2-return needle cap is used with one hand, but pulling the needle out of the needle cap still requires two-hand operation, which increases the risk of needle stick injuries. The existing needle cap holder usually has a circular base, which is placed on the instrument placement table, the needle cap holder entrance is perpendicular to the base, and the needle cap can be inserted into the holder entrance. However, there are some disadvantages of this kind of fixator: 1. The entrance of the fixator is of a fixed diameter, so it is difficult to adapt to needle caps with different diameters. If the diameter of the entrance of the fixator is significantly larger than the diameter of the needle cap, the needle cap is not easy to fix. The needle cap is not easy to insert or remove after insertion; 2 The entrance of the fixator is small and deep, which is not conducive to cleaning and disinfection. Therefore, in stomatology diagnosis and treatment, medical staff need a needle cap return device with reasonable design and simple structure to solve the above problems.

SUMMARY OF THE INVENTION

In order to overcome the problem that the existing oral local anesthesia syringe may not be able to be successfully retracted at one time when the needle cap is retracted, and both hands are required to pull out the needle from the needle cap, and in order to solve the problem that the diameter of the entrance of the existing fixator is not necessarily the same as the diameter of the needle cap Matching, unfavorable cleaning and sterilization and other problems, the utility model provides a needle cap retracting device that can hold various diameters of needle caps and has an open structure, so as to realize the two functions of one-hand removal and accurate retracting of the needle cap, and it is convenient and convenient Clean and disinfect.

The technical scheme adopted by the utility model to solve the technical problem is: the needle cap returning device is made of stainless steel, and includes a holder, a handle and a base. There is a layer of rubber pad on the inner side of the gripper, and the diameter of the opening is 0.5cm; the gripper and the handle are connected by connecting joints and elastic steel wires, and the base is fixed on the connecting joints by screws. The gripper can be opened by gripping the handle by hand; the gripper can be closed by releasing the handle. The gripper can open and close freely to clamp the needle cap of common diameter; the rubber pad on the inner side can ensure the retention effect of the needle cap. The base ensures that the entire unit is placed firmly on the table

The beneficial benefits of the utility model are: the needle cap returning device of the utility model fixes the needle cap through the free opening and closing of the holder, thereby realizing the functions of removing and accurately returning needle caps of various diameters with one hand; Open, no hygienic dead corners, conducive to cleaning and disinfection.

Detailed ways

[Example 1]:

The needle cap return device is placed on the operating table through the base 4, the handle 5 is pressed by hand, and the holder 1 can be opened through the elastic wire 6 and the connecting joint 3; put the syringe with the needle cap upside down on the clamping between the rubber pads 2 inside the holder 1, release the handle 5, the holder 1 is closed, and the needle cap is fixed between the rubber pads 2.

[Example 2]:

When the needle needs to be pulled out from the needle cap, the needle can be directly pulled out from the vertical operating table with one hand, and the needle cap can be left between the rubber pads 2 .

[Example] 3:

When it is necessary to put the needle back into the needle cap, directly insert the syringe needle into the needle cap fixed between the rubber sheets 2 with one hand, and then the needle can be put back into the needle cap.
