Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, specifically a protective device for medical needles. Background Technology
[0002] Intravenous injections are very common in hospitals. When the needle is exposed, it is easily contaminated by the outside world. At the same time, the needle may cause accidental injury to medical staff or patients, posing a significant safety hazard.
[0003] In the existing technology, an infusion set is usually put over the needle of an infusion set. However, this type of protective cover is a separate design from the needle of the infusion set. Before using the infusion set, the protective head on the needle needs to be removed. After the needle is used, the protective cover needs to be put back on the outside of the needle. The operation is cumbersome, and the infusion set is easy to lose, making it inconvenient to use.
[0004] Therefore, a protective device for medical needles is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a protective device for medical needles to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical needle protective device, including a needle tip, one end of which is connected to a flexible tube, and a lower cover and an upper cover are provided on the outside of the needle tip, the upper cover and the lower cover being rotatably connected.
[0007] The upper and lower covers are symmetrically fitted with housings on one side, and the two housings are interlocked with each other.
[0008] Preferably, a snap-fit groove is provided inside the housing.
[0009] Preferably, another housing has a snap-fit block installed inside, the snap-fit block being adapted to a snap-fit groove.
[0010] Preferably, the outer side of the housing has symmetrically formed grooves.
[0011] Preferably, a limiting ring is installed at one end of the lower cover, and the limiting ring is sleeved on the outside of the hose.
[0012] Preferably, rubber pads are uniformly installed on the inner wall of the housing.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the limiting ring can restrict the device to the tubing, preventing the device from being lost; at the same time, the upper cover, lower cover and shell can restrict and protect the needle, thereby preventing the needle from randomly pricking people.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a medical needle protective device, including a needle 1, one end of the needle 1 is connected to a flexible tube 2, and a lower cover 4 and an upper cover 3 are provided on the outside of the needle 1, with the upper cover 3 and the lower cover 4 being rotatably connected.
[0022] The upper cover 3 and the lower cover 4 are symmetrically mounted on one side of the housing 5, and the two housings 5 are interlocked with each other.
[0023] like Figure 2 and Figure 3 As shown: a snap-fit groove 7 is provided inside one housing 5, and a snap-fit block 9 is installed inside the other housing 5. The snap-fit block 9 is adapted to the snap-fit groove 7. With the above settings, the snap-fit block 9 can be snapped into the snap-fit groove 7, thereby restricting and fixing the position of the two housings 5, thus protecting the needle 1 inside.
[0024] like Figure 4 As shown: Grooves 10 are symmetrically provided on the outer side of the housing 5; with the above arrangement, the grooves 10 can make it easier for personnel to separate the two housings 5 more quickly, which is convenient for the use of the device.
[0025] like Figure 1 and Figure 3As shown: A limiting ring 8 is installed at one end of the lower cover 4, and the limiting ring 8 is sleeved on the outside of the hose 2; with the above settings, the limiting ring 8 is sleeved on the outside of the hose 2, which can restrict the operation of the entire device and prevent the device from falling off or being lost.
[0026] like Figure 2 and Figure 3 As shown: Rubber pads 6 are evenly installed on the inner wall of the housing 5; through the above settings, the rubber pads 6 can squeeze the handle on the needle 1, thereby restricting and fixing the position of the needle 1, and preventing the needle 1 from moving at will.
[0027] Working principle: When not in use, this device is installed on the outside of the tubing 2 via the limiting ring 8, which can effectively prevent the device from being lost or falling off. After the needle 1 is used up, the two housings 5 separate through the groove 10, and the upper cover 3 and lower cover 4 also separate. Then, the device is moved towards the needle 1, so that the needle 1 is located between the upper cover 3 and lower cover 4, and the handle on the needle 1 is located on the housing 5. Then, the upper cover 3 and lower cover 4 are closed, and the handle is squeezed by the rubber pad 6 inside the housing 5. Then, the position of the two housings 5 is restricted and fixed by the snap-fit block 9 and snap-fit groove 7. Thus, the device completely protects the needle 1 and prevents the needle 1 from being accidentally punctured.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
