Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings and technical solutions needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
The present invention will be further explained with reference to the accompanying drawings.
A puncture needle protection device comprises a needle head protection part A, a needle body protection part B and a handle C. The needle head protection part A is connected with one end of the needle body protection part B, and the other end of the needle body protection part B is connected with the handle C.
The puncture needle is arranged on the handle C, and the safe puncture needle device can be matched with a puncture sheath tube for use.
The puncture needle protection device only has a channel for the puncture needle to pass through, and the puncture needle has two states in the puncture needle, namely a puncture state and a protection state.
The needle body protection part B is of a telescopic structure, a transparent plastic film is selected in the embodiments 1 and 2, so that the state of the puncture needle is convenient to observe, the telescopic effect is easy to control, and the needle body protection part B is in a completely unfolded state and is used for wrapping the puncture needle in a protection state; in the puncture state, the needle body protecting part B is in a compressed state.
Example 1:
the needle head protection part A comprises a needle head limiting module, the needle head limiting module is composed of a baffle plate 1, a spring 2, a baffle plate button 3 and an opening 4, one end of the baffle plate 1 is fixedly connected with one end of the spring 2, the other end of the spring 2 is connected to the inner wall of the needle head protection part A, the baffle plate button 3 is installed at the other end of the baffle plate 1, the baffle plate button 3 penetrates through the needle body protection part A and can move freely, the opening 4 is formed in the baffle plate 1, the opening 4 is used for enabling a puncture needle to freely penetrate through, when the baffle plate button 3 is pressed, the position of the opening 4 is integrally communicated with a channel inside the puncture needle protection device, the puncture needle on the handle C moves outwards through the channel and the opening 4 at the moment, the needle body protection part B is slowly folded, and then; when the puncture is finished and the puncture needle is withdrawn, the needle body protecting part B is gradually unfolded, when the puncture needle is completely withdrawn, the needle head of the puncture needle is just close to the baffle plate 1 and is positioned in the needle body protecting part B, in the state, the baffle plate button 3 is loosened, the baffle plate 1 rebounds under the action of the spring 2, the opening 4 and the channel are in a staggered state at the moment, and the puncture needle is in a protecting state.
Example 2:
the needle head protection part A comprises a funnel part 11, the funnel part 11 also has the needle head limiting function, and the wide opening of the funnel part 11 is close to the handle C. When the puncture needle is used for puncture, the puncture needle directly exits from the puncture needle, the needle head is better positioned at the position of the funnel part 11 close to the narrow opening, and the diameter of the funnel part 11 at the position is slightly larger than that of the puncture needle, so that the limiting effect is achieved.
In order to better realize the limiting effect, the needle head protecting part A is made of elastic rubber materials.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
