The utility model provides a puncher for protecting a bottle at the end of a traction needle, as shown in figure 1, when the puncher 1 is used, the puncher is vertically arranged on the upper side of the protecting bottle 2, and can punch a bottle stopper 21 of the protecting bottle 2. Because the traction needle is thicker, the rubber plug of the medicine bottle is not easy to puncture, the traction needle shakes when the protection bottle 2 is forcefully installed, the pain of a patient is increased, and the risk that the traction needle punctures the bottom of the medicine bottle to damage medical staff exists. Therefore, the punching device 1 is required to punch the bottle stopper 21 of the protective bottle 2 before use, so that medical staff can simply and conveniently sleeve the protective bottle 2 at the tip end of the traction needle, and secondary injury to a patient due to difficult installation of the protective bottle 2 is avoided.

Specifically, the perforating device 1 includes an outer barrel structure 11 and a perforating needle structure 12, as shown in fig. 2. The outer barrel structure 11 has a proximal end and a distal end spaced apart from the proximal end along the longitudinal axis, and the distal end is disposed in snap engagement with the end of the protective bottle 2; when punching the bottle stopper 21 at the end part of the protection bottle 2, the end part of the outer cylinder structure 11 can clamp the protection bottle 2, so that the punching device 1 and the protection bottle 2 are relatively fixed, and the punching device 1 is ensured to punch the end part of the protection bottle 2 rapidly and accurately.

Specifically, the perforation needle structure 12 is coaxially sleeved inside the outer cylinder structure 11, and is movable in the height direction inside the outer cylinder structure 11. The lower extreme of perforating needle structure 12 is relative with the upper end of protection bottle 2, when needs are punched to the bottle plug 21 of protection bottle 2, can push down perforating needle structure 12, makes perforating needle 122 puncture protection bottle 2 bottle plug 21 and punches, and after punching, upwards pull perforating needle structure 12 to take out perforating needle 122 from protection bottle 2 bottle plug 21, accomplish the punching.

The outer barrel structure 11 includes a clamping mechanism 111 and an outer barrel body 112, see fig. 2. The clamping mechanism 111 is arranged at the far end of the outer cylinder body 112, symmetrically arranged on the inner wall of the outer cylinder body 112 and extends out of the outer cylinder body 112, and clamping claws of the clamping mechanism 111 extending out of the outer cylinder body 112 are clamped at the upper end of the protection bottle 2 to fix and limit the protection bottle 2. When the bottle stopper 21 of the protection bottle 2 is perforated, the clamping mechanism 111 clamps the protection bottle 2 to fix the protection bottle 2 to prevent the protection bottle 2 from being deflected or the perforation from failing due to unstable support of the protection bottle 2 during perforation.

Wherein, the outer cylinder body 112 is sleeved outside the perforating needle structure 12, and the perforating needle structure 12 can slide up and down in the outer cylinder body 112. The outer cylinder body 112 is hinged to the clamping mechanism 111. When the multifunctional perforating needle structure is used, medical staff pushes the perforating needle structure 12 downwards and props against the end part of the clamping mechanism 111 in the outer cylinder body 112, and because the clamping mechanism 111 is hinged by a screw at the center, the perforating needle structure 12 limits the end of the clamping mechanism 111 extending out of the outer cylinder body 112 at the same time, so that the clamping pliers 1111 of the clamping mechanism 111 can stably clamp the bottleneck of the protection bottle 2, and the clamping state can not be loosened. Meanwhile, the bottom of the outer cylinder body 112 is also provided with a needle outlet, the circular needle outlet is a passage for the punching needle 122 to enter and exit the outer cylinder body 112, the diameter of the needle outlet is slightly larger than the outer diameter of the punching needle 122, and the needle outlet plays a role in guiding the punching needle 122, so that the protection bottle 2 is conveniently punched.

Referring to fig. 2 in detail, the perforating needle structure 12 includes a push rod assembly 121 and a perforating needle 122, wherein the push rod assembly 121 is sleeved inside the outer cylinder body 112 and is disposed in the middle of the perforating needle structure 12; the perforating needle 122 is fixedly provided at the lower end of the push rod assembly 121, and the tip of the perforating needle 122 faces the bottle stopper 21 protecting the upper end of the bottle 2. When the push rod assembly 121 is pushed downward, the perforating needle 122 pierces the bottle stopper 21 at the upper end of the protection bottle 2, and perforates the protection bottle 2.

The push rod assembly 121 can drive the perforating needle 122 to press down into the bottle stopper 21 or the push rod assembly 121 can move in the height direction in the outer cylinder body 112. When pushing the push rod assembly 121 downwards, the punching needle 122 is driven to press downwards to punch the bottle stopper 21, or the push rod assembly 121 is pulled upwards to pull out the punching needle 122.

As shown in fig. 1 and 2, specifically, the clamping mechanism 111 includes at least 2 clamping pincers 1111, preferably 3 clamping pincers 1111, and the clamping pincers 1111 are symmetrically disposed on the inner wall of the distal end of the outer cylinder body 112 with the central axis of the outer cylinder body 112 as the center. The clamping jaw 1111 is hinged on the inner wall of the outer cylinder body 112, and the upper end of the clamping jaw 1111 is located in the inner cavity of the outer cylinder body 112, and the bottom of the lower end of the outer cylinder body 112 is provided with a movable hole 1121 corresponding to the clamping jaw 1111, as shown in fig. 3. The lower end of the clamping jaw 1111 extends out of the outer cylinder body 112 from the movable hole 1121, when the push rod assembly 121 is pushed downward, the push rod assembly 121 pushes the upper end of the clamping jaw 1111 against and contacts the inner wall of the outer cylinder body 112, and at this time, the lower end of the clamping jaw 1111 is also in a limited state due to the limitation of the push rod assembly 121 to the upper end of the clamping jaw 1111, so as to tightly clamp the bottle stopper 21 and the bottle neck of the protection bottle 2. The inside of clamping jaw 1111 lower extreme still is provided with non slipping block 1112, can butt protection bottle 2 when clamping jaw 1111 carries out the centre gripping to protection bottle 2, prevents protection bottle 2 from slipping from clamping jaw 1111, and is fixed more firm.

The push rod assembly 121 includes a piston stem 1211, a push rod 1212, and a sealing rubber plug 1213, shown in detail in fig. 2. The piston stem 1211 is disposed at the end of the push rod 1212 and has a disc shape to cover the end of the push rod 1212 so as to exert a downward force on the push rod 1212 to push the push rod assembly 121 downward when the stopper 21 of the protection bottle 2 is perforated. The diameter of the piston handle 1211 is larger than that of the outer cylinder body 112, and the large area is easier to press and exert force.

One end of the push rod 1212 is fixedly connected with the center of the piston handle 1211 and is vertically arranged on the piston handle 1211, and when in use, the push rod 1212 can be pressed downwards through the piston handle 1211 to apply pressure to the punching needle 122 to penetrate the bottle stopper 21.

Wherein a sealing rubber stopper 1213 is provided at the other end of the push rod 1212 remote from the piston stem 1211 and is fitted with the inner diameter of the outer cylinder body 112, as shown in fig. 2. The sealing rubber plug 1213 can make the push rod 1212 slide smoothly in the outer cylinder body 112, and at the same time, plays a role of buffering when the lowermost end of the push rod 1212 contacts the bottom surface of the outer cylinder body 112. The proximal edge of the outer barrel body 112 expands outwardly into a grip 113, the grip 113 having a diameter greater than the diameter of the plunger stem 1211. When the medical staff pushes the push rod 1212 downwards, the pressure can be better applied to the perforating needle structure 12 through the cooperation of the piston handle 1211 and the handle 113, so that the perforating convenience is improved.

Specifically, the diameter of the punching needle 122 is set to be equal to or slightly smaller than the diameter of the traction needle, so that the punched protection bottle 2 can be more effort-saving and accurately sleeved outside the end of the traction needle, and the end of the traction needle can be firmly clamped by a needle hole penetrated by the punching needle 122 on the bottle stopper 21, so that the protection bottle 2 is prevented from slipping from the end of the traction needle. And in this embodiment, the perforating needles 122 with different diameters can be arranged according to the traction needles with different types, so that the protection bottle 2 can be prepared for the traction needles with different types, and the bottle plug holes of the protection bottle 2 are matched with the diameters of the traction needles.

The inner side of the end of the clamping jaw 1111 is further provided with a non-slip block 1112, as shown in fig. 1 and 2. The slider 1112 is made of elastic material such as rubber and has a large friction force. The anti-skid block 1112 can be extruded when the protection bottle 2 is clamped, the pressure and friction of the protection bottle 2 are increased through deformation of the contact surface of the anti-skid block 1112 and the protection bottle 2 to a certain extent, and the protection bottle 2 is better fixed to complete punching.

The protection bottle 2 comprises a bottle plug 21 and a bottle body 22, the bottle plug 21 corresponds to the tip end of the punching needle 122, and a storage cavity is formed in the bottle body 22 and can be matched with the end of the traction needle, so that the end of the traction needle is prevented from being scratched or stabbed on a patient and medical staff, and unnecessary injuries are caused.

As a preferred choice, the protecting bottle 2 is a glass bottle of cefuroxime sodium for injection, and the bottle stopper 21 of the glass bottle is made of rubber, so that the tip of the traction needle and the traction needle inserted into the accommodating cavity of the protecting bottle 2 can be limited, and the problems of shaking and falling of the protecting bottle 2 and the traction needle can be avoided; the cefuroxime sodium belongs to an antibiotic medicine, so that the containing bottle of the cefuroxime sodium is selected, unnecessary infection can be avoided, the end of the traction needle is firmly sleeved, the damage to a patient is avoided, the secondary utilization of the glass bottle is realized, and the resource is saved.

The application process of the embodiment of the utility model is as follows:

1. firstly, a perforating needle 122 with a corresponding diameter is selected according to traction needles of different types, a prepared protective bottle 2 is placed at the lower end of the perforating device 1 and is opposite to the needle position of the perforating needle 122, and the distance between the perforating device 1 and the protective bottle 2 is adjusted, so that the bottle stopper 21 and the bottle mouth of the protective bottle 2 are positioned in a clamping clamp 1111.

2. Next, after the distance and angle between the punch device 1 and the protection bottle 2 are adjusted, the handle 113 is held by two fingers, the thumb presses the piston handle 1211 downward, and the piston handle 1211 is pressed, so that the push rod 1212 and the punch needle 122 are pressed downward. After the push rod 1212 is moved downward to a certain distance, the side wall of the push rod 1212 will press the upper end of the clamping jaw 1111 against the inner wall of the outer cylinder body 112, the upper end of the clamping jaw 1111 is limited, so that the lower end of the clamping jaw 1111 is tightly held against the bottle neck and the bottle stopper 21 of the protection bottle 2, so that the protection bottle 2 is fixed and cannot slip when being pressed downward;

pushing on the plunger stem 1211 continues until the piercing needle 122 pierces the stopper 21 to complete the piercing. After the perforation is completed, the plunger stem 1211 and push rod 1212 are pulled upward, causing the perforating needle 122 to be withdrawn from the stopper 21.

3. The bottle stopper 21 of the protection bottle 2 is perforated, and the diameter of the perforating needle 122 is equal to or slightly smaller than the diameter of the traction needle, so that the end part of the traction needle can be conveniently inserted into the needle hole on the bottle stopper 21 in a labor-saving manner during use, and medical staff only needs to align the end part of the traction needle to the needle hole of the bottle stopper 21 of the protection bottle 2 for insertion, thereby avoiding causing additional pain to patients. The rubber material of the bottle stopper 21 of the protection bottle 2 and the design that the diameter of the punching needle 122 is equal to or slightly smaller than the diameter of the used traction needle enable the bottle stopper 21 of the protection bottle 2 to tightly clamp the penetrated traction needle, so that unnecessary pain to a patient caused by the traction needle scratch by the slipping of the protection bottle 2 is avoided, the probability of injury of medical staff during installation of the protection bottle 2 is reduced, and the working efficiency is improved.
