Referring to fig. 1-4:
example 1
The utility model provides a disposable insulin syringe needle, including syringe needle connecting seat 1, the end fixing of syringe needle connecting seat 1 has fixing base 2, syringe needle connecting seat 1 internal fixation has needle tubing 3, the one end of needle tubing 3 is located syringe needle connecting seat 1, the other end of needle tubing 3 runs through fixing base 2, the one end that syringe needle connecting seat 1 was kept away from to fixing base 2 is fixed with soft rubber tube 4, and soft rubber tube 4 covers the outside of locating the needle tubing 3 corresponding end, soft rubber tube 4 keeps away from the one end closure setting of fixing base 2 and can be pierced by needle tubing 3, soft rubber tube 4 is kept away from the one end of fixing base 2 and is provided with the shielding mechanism 5 that is used for sheltering from needle tubing 3 tip after needle tubing 3 uses.
It should be noted that, shielding mechanism 5 includes a left hollow installation block 6 and a right hollow installation block 7 which are embedded and fixed at one end of flexible rubber tube 4 far away from fixing seat 2, left hollow installation block 6 and right hollow installation block 7 are oppositely arranged, and shielding components which are symmetrically arranged and have the same structure are arranged at the inner sides of left hollow installation block 6 and right hollow installation block 7. Preferably, the shielding assembly comprises a baffle plate 14 fixed on the inner side of the corresponding left hollow mounting block 6 or right hollow mounting block 7, a sliding block 9 is slidably matched on the baffle plate 14, one side of the sliding block 9 is fixedly provided with a stop block 10, the end part of which movably penetrates through the inner side wall of the soft rubber tube 4, the other side of the sliding block 9 is fixedly provided with a spring 11, and the other end of the spring 11 is fixedly connected with the corresponding left hollow mounting block 6 or right hollow mounting block 7. Specifically, one side of the two sliding blocks 9, which are far away from each other, is fixed with the same stay wire 12 positioned below the needle tube 3. The length of the spring 11 is greater than the length of the diaphragm 14, and the slider 9 is rectangular in shape.
The partition 14 is provided with a first threading hole 8 through which the pull wire 12 passes, and the lower end of the soft rubber tube 4 is provided with a second threading hole 13 which is communicated with the corresponding left or right hollow mounting block 6 or 7 and through which the pull wire 12 passes. The lower extreme of soft rubber tube 4 is provided with the mounting hole with dog 10 size adaptation, and the tip activity of dog 10 is pegged graft in the mounting hole. The shape of the soft rubber tube 4 is cylindrical, and the inner diameter of the soft rubber tube 4 is consistent with the size of the needle tube 3, so that the needle tube 3 can normally pierce the stay wire 12.
Working principle: in the utility model, it should be noted that at the initial time, both springs 11 are in a compressed state, at this time, both sliding blocks 9 are not moved under the traction of the stay wire 12, when in use, the needle connecting seat 1 is connected with the injection pen, and then the left hollow mounting block 6 and the right hollow mounting block 7 are pushed to move so as to shrink the soft rubber tube 4, so that the end part of the needle tube 3 punctures the closed end of the soft rubber tube 4, when in puncture, the stay wire 12 is punctured firstly, and because the needle tube 3 is between the two stop blocks 10 when the stay wire 12 is punctured, the position of the stop blocks 10 cannot be changed, and when the soft rubber tube 4 is continuously shrunk, the needle tube 3 can leak out, thereby being convenient to use.
After the needle tube 3 is used, under the elastic restoring force of the soft rubber tube 4, the soft rubber tube 4 can cover the end part of the needle tube 3 again, at this time, because the stay wire 12 is broken, the whole of the sliding block 9 and the stop block 10 cannot be pulled, under the action of the spring 11 in a compressed state, the two stop blocks 10 move to seal the inner side of the soft rubber tube 4, and then the end part of the needle tube 3 cannot be opened, so that the end part of the needle tube 3 cannot be used continuously, and then the infection risk is reduced.
The exemplary implementation of the solution proposed by the present disclosure has been described in detail hereinabove with reference to the preferred embodiments, however, it will be understood by those skilled in the art that various modifications and adaptations can be made to the specific embodiments described above and that various combinations of the technical features, structures proposed by the present disclosure can be made without departing from the scope of the present disclosure, which is defined by the appended claims.
