Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
As shown in figures 1 to 3, the utility model provides a novel needle extractor for an infusion port, which comprises
The clamping device comprises a first clamping arm 1 and a second clamping arm 9, wherein the first clamping arm 1 and the second clamping arm 9 are connected through a hinge shaft 2;
the clamp comprises a first clamp handle 6 and a second clamp handle 10, wherein the first clamp handle 6 is connected with a first clamp arm 1 through a detachable rod 3, and the second clamp handle 10 is also connected with a second clamp arm 9 through a detachable rod 3;
the two chucks 4 are respectively fixed at the top ends of the first clamping arm 1 and the second clamping arm 9;
two strip-shaped silica gel pads 5, the two strip-shaped silica gel pads 5 are respectively and movably arranged at the bottoms of the two chucks 4.
The utility model has the advantages that:
connect the arm lock and the clamp holder together through the detachable rod, it is more convenient to install, dismantle and preserve, arm lock and clamp holder vertically design make medical personnel dynamics and the top surface of infusion port perpendicular when pulling out the needle, thereby make the power of upwards pulling out the needle better transmit, it is more laborsaving to pull out the needle, it can effectively contact with patient's skin and make and pull out the needle ware and can not harm patient's skin to have designed the silica gel pad bottom the chuck, the removable design of silica gel pad makes one pull out the needle ware and can use and can not take place the infection to a plurality of patients, the cost is saved.
Preferably, the combined shape of the first clamping arm 1 and the second clamping arm 9 is an 'X' shape, and the two chucks 4 can be close to each other to clamp the undamaged needle by manually rotating the tail ends of the two clamping arms.
Preferably, one end of the detachable rod 3 is in threaded connection with the tail end of the clamping arm 1, and the other end of the detachable rod 3 is fixed at the bottom end of the clamping handle 6. Convenient replacement or maintenance, and also convenient cleaning.
Preferably, the axis of the detachable rod 3 is perpendicular to the axes of the first and second clamp holders 6, 10. Because when pulling out the needle, can dismantle the axis of pole 3 and can't harm the needle perpendicular, first clamp holder 6 and second arm lock 6 are parallel with harmless needle, and main pulling force direction is parallel with clamp holder axis to it is more light laborsaving to make to pull out the needle.
Preferably, the cartridge 4 has a circular arc or a polygonal line shape in a plan sectional shape. If the chuck 4 is a fold line shape, the fold angle of the chuck 4 is an obtuse angle, so that the bending degree of the strip-shaped silica gel pad 5 is smaller, and the strip-shaped silica gel pad is easier to penetrate through.
As shown in fig. 2 and 3, a T-shaped groove 7 is formed in the chuck 4, and the strip-shaped silicone rubber pad 5 is arranged in the T-shaped groove 7 in a penetrating manner. The strip-shaped silica gel pad 5 is a strip-shaped silica gel pad, namely a silica gel strip. In addition, the silica gel pad can also be made of elastic materials such as latex pads, rubber pads and the like with the same shape.
Preferably, the track of the T-shaped groove 7 is arc-shaped, and one end of the T-shaped groove 7 is provided with a penetrating port 8 penetrating through the top end face of the chuck 4. The end surfaces of the inserting hole 8 and the T-shaped groove 7 are both T-shaped, so that the silica gel pad can be inserted into the inserting hole and can not fall out. When the strip-shaped silica gel pad 5 is replaced, the used silica gel pad is firstly drawn out from the inserting port 8, and then the new sterilized strip-shaped silica gel pad 5 is completely inserted into the T-shaped groove 7 from the inserting port 8, so that the replacement of the silica gel pad is completed, the same needle pulling device can be used for operating different patients, and the infection is avoided. The replaced strip-shaped silica gel pad 5 is also convenient for centralized cleaning and disinfection.
Preferably, the end surface of the strip-shaped silica gel pad 5 is in an I shape, and the area of the bottom surface of the strip-shaped silica gel pad 5 is larger than that of the bottom surface of the chuck 4. When the medical staff pulls out the needle, the strip-shaped silica gel pad 5 is directly contacted with the skin of the patient, and the hard part of the chuck 4 is not contacted with the skin, thereby avoiding the skin from being injured by clamping or giving bad touch feeling to the skin of the patient.
It should be added that when the two chucks are completely closed, the closed clamping area formed inside the two chucks is smaller than the pintle of the nondestructive needle (the pintle is the connecting component between the nondestructive needle and the injector and is fixed on the top end of the needle), so that the needle extractor of the utility model can clamp and extract the straight-head nondestructive needle as well as the elbow or butterfly-wing nondestructive needle, and the application range is wider.
The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
