Problems solved by technology

Because there are bacteria in the patient's mouth, the wound is easy to induce infection, and because many diseases can be transmitted by saliva, the danger of stab wounds is very high
In the prior art, the protection of tools with spikes mainly adopts sleeve-type protection structures made of elastic materials or hard plastics, for example: Chinese application number: 201310458791.8 needle tip protection sleeve, the main problems are: 1. Different In some medical tools, due to the different sizes of the bases fixedly connecting the spikes, the protective cover cannot be effectively fixed with the tool and is easy to loosen; 2. Since the spikes of some medical tools are curved, the protective sleeve cannot effectively surround the sharp Assassin
In addition, since the spiked tool is not disposable, it is impossible to adopt the open indwelling needle with automatic withdrawal of the needle such as the Chinese application number 201220379826. It can only be used for straight-line spiked tools, and cannot be used for curved ones, and the telescopic sleeve itself affects the disinfection of tools

Embodiment Construction

[0020] Such as figure 1 The shown protective sheath for needle-point instruments includes a sleeve 1 made of elastic material. The sleeve 1 has a through-hole structure with openings 10 and 11 on both sides, and the opening is square. Moreover, the sleeve 1 is in a shape in which the openings 10 and 11 at both ends shrink toward the middle, and the length of the narrowing point 12 from the openings on both sides is different.

[0021] Such as figure 2 As shown: the inner wall of the constriction 12 is a hole, and the diameter of the hole is taken from the range of 2 mm to 5 mm. This solution ensures that when the linear spiked portion 3 passes through the constriction 12, the spiked portion 3 will expand the hole, and due to the resilience of the elastic material, the sleeve 1 and the tool will be constrained and then fixed.

[0022] Such as image 3 As shown: when the spiked part 3 is curved, the narrowed part, even if the cannula 1 and the medical spiked tool are mutuall...

Abstract

The invention discloses a protective sleeve for a needle-point instrument. The protective sleeve comprises a sleeve made of elastic material, the sleeve is of a through-hole structure with the two open sides, the two ends of the sleeve are open, the sleeve shrinks from the two open sides toward the middle to form a shrinkage narrow part, and the distances from the shrinkage narrow part to the two sides are different. According to the technical scheme, the two sides are open, and therefore breathability is good. The shrinkage narrow part is arranged in the middle, the protective sleeve and the medical sharp instrument are convenient to mutually restrain, and besides the protective sleeve can be bent for use and is convenient to match with a bent sharp part. The open sections on the two sides are designed to be different in length so that when the protective sleeve is bent, the sharp part can be convenient to embed from the short open section, and the long open section can effectively ensure that the sharp part does not exceed the protection range of the protective sleeve.

Description

technical field [0001] The invention relates to the field of protective sheaths, in particular to a needlepoint instrument protective sheath. Background technique [0002] In the existing medical field, medical tools with spikes appear widely in dental clinics or orthopedic clinics. In addition to the straight type, the sharp part also has a curved type. After use, it is placed on a medical disinfection tray or inserted into a tool barrel. The sharp part of the tool after use is exposed, and the doctor is often stabbed by the sharp part when changing the tool continuously. Because there are bacteria in the patient's mouth, the wound is easy to induce infection, and because many diseases can be transmitted by saliva, the harm of stabbing is very great. In the prior art, the protection of tools with spikes mainly adopts sleeve-type protection structures made of elastic materials or hard plastics, for example: Chinese application number: 201310458791.8 needle tip protection s...
