Examples

Referring to fig. 1-4, an insulin needle holder comprises a housing 1 and a clamping member 4. Wherein, the shell 1 is cylindrical, which is convenient for grasping. The casing 1 is hollow inside, and a first circular jack 2 has been seted up at its top surface middle part, and the inboard of first circular jack 2 is provided with first silica gel layer 3, has elasticity, the increase frictional force.

The clamping member 4 includes a pressing block 5, a clamping plate 8, and a spring 9. The clamping plate 8 is slidably mounted in the housing 1, specifically, two sliding rails 10 are disposed at an interval on the inner side of the housing 1, and two opposite sides of the clamping plate 8 are slidably connected to the two sliding rails 10, respectively. In this embodiment, the housing 1, the pressing block 5, the clamping plate 8 and the slide rail 10 are made of plastic, and have better mechanical strength and lower cost.

According to briquetting 5 and spring 9 and link to each other with splint 8's relative both sides respectively, wear to establish casing 1 according to briquetting 5 activity to relative casing 1 protrusion, spring 9 is located casing 1, and spring 9's axis direction and the radial direction parallel arrangement of first circular jack 2, the length direction of slide rail 10 and spring 9's flexible direction parallel arrangement, spring 9's flexible direction is axis direction promptly.

A second circular jack 6 is formed in the middle of the clamping plate 8, and when the spring 9 is in a natural state, the horizontal projection of the second circular jack 6 is intersected with the horizontal projection of the first circular jack 2. When the pressing block 5 compresses the spring 9 through the clamping plate 8, the second circular jack 6 is opposite to the first circular jack 2 up and down, and a protective sleeve with an insulin needle head is conveniently placed. Wherein, the inboard of second circular jack 6 is provided with second silica gel layer 7, has elasticity, increases frictional force. The diameters of the first circular jack 2 and the second circular jack 6 are equal, so that the objects placed in the first circular jack 2 and the second circular jack 6 can be conveniently matched and clamped. The first circular jack 2 is intersected with the second circular jack 6, and a clamping structure is formed under the elastic force action of the spring 9, so that the embedded protective sleeve is well protected and fixed. The setting on first silica gel layer 3 and second silica gel layer 7 improves the frictional force of first circular jack 2 and the circular jack 6 of second to the protective sheath, and then improves the fixed effect to the protective sheath.

In addition, the bottom of the inner side of the shell 1 is provided with a bracket 11, the bracket 11 is positioned under the first circular jack 2, and the bracket 11 is used for supporting the bottom of the protective sleeve, so that the fixing effect on the protective sleeve can be further improved. The bottom of casing 1 is provided with sucking disc 12, and sucking disc 12 can be fixed whole device on the operation mesa, and then makes things convenient for operating personnel to carry out one-hand operation, improves the convenience of use.

The utility model is used for clamping and fixing the insulin needle, is convenient for operators to take and place the insulin needle, can avoid the problem that the fingers of the operators are stabbed, and improves the safety. When an operator takes the needle, the pressing block 5 of the clamping piece 4 is pressed firstly, so that the second circular insertion hole 6 moves horizontally along with the clamping plate 8 and is opposite to the first circular insertion hole 2 up and down; then, the needle head together with the protective sleeve is arranged in the second circular jack 6 of the splint 8; then, the pressing block 5 is loosened, the clamping plate 8 is reset under the action of the elastic force of the spring 9, the second circular insertion hole 6 is staggered with the first circular insertion hole 2, and the protective sleeve is clamped; and finally, connecting the front end of the insulin pen with the needle head through threads, and taking out the insulin pen for use. When the needle head is abandoned, the reverse operation is carried out, the operation is carried out without holding the protective sleeve by hand, and the protective sleeve and the needle head which are finally taken out are discarded into the sharp instrument box for recycling. The specific operation of discarding the needle head is as follows: an operator firstly places the used needle head in the protective sleeve and rotates the needle head to separate the needle head from the front end of the insulin pen; then, the pressing block 5 is pressed to enable the second circular jack 6 to be opposite to the first circular jack 2 up and down, and the function of loosening the protective sleeve is achieved; finally, the protective sheath is removed with the needle and discarded.

The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
