Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a connector capable of wrapping a heparin cap. Background Art
[0002] A heparin cap is a matching connector device containing heparin components, generally used for injecting drugs. The purpose is to lock the connector and inject sodium heparin, which can prevent blood reflux and anticoagulation. It is commonly used in intravenous indwelling needle infusion, intravenous indwelling catheterization, etc., and can effectively reduce repeated skin punctures and extend the service life of intravenous indwelling needles and indwelling catheters.
[0003] Currently, when injecting drugs into an indwelling needle or indwelling catheter, it is generally necessary to disinfect the latex plug at the input end of the heparin cap. After disinfection, it can be connected to an infusion set or syringe, etc. However, medical staff need to disinfect each time they operate, which is rather troublesome and increases the work burden of medical staff. Moreover, the heparin cap after injecting drugs is exposed to the external environment and is easily contaminated. Therefore, in view of the above problems, we propose a connector capable of wrapping a heparin cap. Content of the Utility Model
[0004] In view of the above problems, the purpose of the utility model is to provide a connector capable of wrapping a heparin cap, which completely wraps the heparin cap therein during use to protect the heparin cap and disinfect the heparin cap at the same time, avoiding the need for medical staff to disinfect each time they operate and reducing the work burden of medical staff.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a connector capable of wrapping a heparin cap, including a heparin cap body, an inner tube, and a disinfection member. The heparin cap body is used for externally connecting a pipeline to inject drugs. The inner tube is a tubular shape with one end open. The heparin cap body is slidably installed inside the inner tube. A deformation ring for fixing the heparin cap body is arranged inside the inner tube. After the heparin cap body is located inside the inner tube, the heparin cap body is fixed by being extruded by the deformation ring. The disinfection member includes a liquid storage cavity for storing disinfectant, a disinfection sponge connected to the inner wall of the liquid storage cavity, and a push rod connected to the outer wall of one end of the liquid storage cavity. One end of the push rod extends to the outside of the inner tube and is slidably connected to the inner tube.
[0006] The beneficial effect of the utility model is that: by slidably installing the heparin cap body connected to the venous pipeline into the inner tube, the deformation ring extrudes and fixes the heparin cap body, and at the same time, the disinfection member disinfects the input end of the heparin cap body. When injecting drugs, the push rod pushes the heparin cap body out of the inner tube, and the disinfected heparin cap body can be directly used, which not only protects the heparin cap but also reduces the work burden of medical staff.
[0007] To limit the heparin cap body;
[0008] As a further improvement of the above technical solution: a retaining ring for limiting the heparin cap body is provided inside the inner tube, and the inner diameter of the retaining ring is larger than the outer diameter of the liquid storage cavity.
[0009] The beneficial effect of this improvement is that when the heparin cap body is pushed into the inner tube, the heparin cap body can be blocked by the retaining ring, which can help the user judge the pushing position of the heparin cap body, and avoid the situation that the heparin cap body is pushed in too little and is not firmly fixed, as well as the situation that the heparin cap body is pushed in too deep and affects the use.
[0010] In order to reduce the accidental touch of the push rod;
[0011] As a further improvement of the above technical solution: the outer wall of the inner tube is threadedly connected with an outer tube, and one end of the push rod away from the liquid storage cavity is rotatably connected to the inner wall of one end of the outer tube.
[0012] The beneficial effect of this improvement is that the push rod is exposed outside, and it is very easy to be accidentally pushed or pulled under the action of external force, and it may be easily damaged by external force collision. The setting of the outer tube can protect the push rod, and it is convenient to use the push rod, while reducing the accidental touch of the push rod.
[0013] In order to increase the protection effect on the heparin cap body;
[0014] As a further improvement of the above technical solution: when the heparin cap body is fixed inside the inner tube, the output end of the heparin cap body is located inside the inner tube.
[0015] The beneficial effect of this improvement is that after the heparin cap body is fixed inside the inner tube, there are two situations where the heparin cap body is completely wrapped by the inner tube. One is that the output end of the heparin cap body is flush with the opening end of the inner tube, and the other is that the output end of the heparin cap body is located inside the inner tube. Compared with the former, the latter has a smaller contact probability with the heparin cap body, reduces the pollution and damage of the heparin cap body by external substances, and reduces the possibility of infection.
[0016] In order to disinfect precisely;
[0017] As a further improvement of the above technical solution: the disinfection sponge is adapted to the size of the input end of the heparin cap body.
[0018] The beneficial effect of this improvement is that the design that the disinfection sponge has the same size as the heparin cap body can make the disinfection effect concentrated on the input end, avoid the contact between the disinfection sponge and the area that does not need to be disinfected, improve the accuracy and effectiveness of disinfection, and eliminate potential pathogens and pollutants to the greatest extent.
[0019] In order to assist in rotating the outer tube;
[0020] As a further improvement of the above technical solution: auxiliary rings are provided at the open end of the inner tube and at one end of the outer tube far away from the open end, and anti-slip patterns are provided on both of the auxiliary rings.
[0021] The beneficial effect of this improvement is that when the push rod needs to be used, hold the two auxiliary rings with both hands respectively, and rotate the hand holding the auxiliary ring on the outer tube. At the same time, the anti-slip patterns can increase the friction between the auxiliary ring and the hand, so as to facilitate rotating the outer tube to drive the push rod to push or pull outwards.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.
[0029] Such as Figures 1-5As shown in the figure, a connector that can wrap a heparin cap includes a heparin cap body 1, an inner tube 2, and a disinfection member. The heparin cap body 1 is used for injecting drugs through an external pipeline. The inner tube 2 is a tubular shape with one end open. The heparin cap body 1 is slidably installed inside the inner tube 2. A deformation ring 3 for fixing the heparin cap body 1 is provided inside the inner tube 2. After the heparin cap body 1 is located inside the inner tube 2, the heparin cap body 1 is squeezed and fixed by the deformation ring 3. The disinfection member includes a liquid storage cavity 401 for storing disinfectant, a disinfection sponge 402 connected to the inner wall of the liquid storage cavity 401, and a push rod 403 connected to the outer wall of one end of the liquid storage cavity 401. One end of the push rod 403 extends to the outside of the inner tube 2 and is slidably connected to the inner tube 2;
[0030] Specifically, the heparin cap body 1 mainly includes a main body, a latex plug at the input end of the main body, and a connection port at the output end of the main body. When drug injection is required, a needle is inserted into the latex plug, and the liquid medicine is injected through the pipeline in the main body. After the heparin cap body 1 is used up, the heparin cap body 1 is pushed into the inner tube 2. At this time, the input end of the heparin cap body 1 squeezes the deformation ring 3, and the deformation ring 3 deforms. When the heparin cap body 1 completely enters the inner tube 2, the deformation ring 3 simultaneously squeezes the heparin cap body 1 to squeeze and fix the heparin cap body 1. The deformation ring 3 can be made of materials such as rubber and silica gel. At the same time, the push rod 403 is pushed to make the disinfection sponge 402 contact the heparin cap body 1 to disinfect the heparin cap body 1. The disinfectant in the liquid storage cavity 401 can be iodophor, alcohol, etc. In addition, during the production of this device, the disinfectant can be filled into the liquid storage cavity 401 in advance, and the open end of the inner tube 2 can be heat-sealed to prevent the evaporation of the disinfectant. When in use, the heat-sealing film is torn off. The disinfection sponge 402 has been hardened to avoid excessive overflow of the disinfectant and avoid the residue of the disinfectant while disinfecting the latex plug. When it needs to be used next time, the push rod 403 is pushed. The push rod 403 pushes the liquid storage cavity 401, and the liquid storage cavity 401 pushes the heparin cap body 1 to push the heparin cap body 1 out of the inner tube 2. Since the latex plug is continuously disinfected, there is no need to disinfect the latex plug again and it can be directly used. After use, the heparin cap body 1 is pushed into the inner tube 2 again, and so on until the disinfectant is used up and disinfection is impossible. When in use, the heparin cap is completely wrapped therein to protect the heparin cap and disinfect the heparin cap at the same time, avoiding the need for medical staff to disinfect each time and reducing the work burden of medical staff.
[0031] Preferably, a retaining ring 5 for limiting the heparin cap body 1 is provided inside the inner tube 2. The inner diameter of the retaining ring 5 is larger than the outer diameter of the liquid storage cavity 401. When the heparin cap body 1 is pushed into the inner tube 2, the heparin cap body 1 can be blocked by the retaining ring 5, which can help the user judge the pushing position of the heparin cap body 1, avoiding the heparin cap body 1 being pushed in too little and being unstable, and being pushed in too deep and affecting the use.
[0032] Preferably, the outer wall of the inner tube 2 is threadedly connected to an outer tube 6. One end of the push rod 403 away from the liquid storage cavity 401 is rotatably connected to the inner wall of one end of the outer tube 6. The push rod 403 is exposed outside, and it is very easy to be accidentally pushed or pulled under the action of an external force, and it may be easily damaged by an external collision. The setting of the outer tube 6 can protect the push rod 403, facilitate the use of the push rod 403, and reduce the accidental touch of the push rod 403.
[0033] Preferably, when the heparin cap body 1 is fixed inside the inner tube 2, the output end of the heparin cap body 1 is located inside the inner tube 2. After the heparin cap body 1 is fixed inside the inner tube 2, there are two situations where the heparin cap body 1 is completely wrapped by the inner tube 2. One is that the output end of the heparin cap body 1 is flush with the open end of the inner tube 2, and the other is that the output end of the heparin cap body 1 is located inside the inner tube 2. Compared with the former, the latter has a smaller contact probability with the heparin cap body 1, reduces the contamination and damage of the heparin cap body 1 by external substances, and reduces the possibility of infection.
[0034] Preferably, the disinfection sponge 402 is adapted to the size of the input end of the heparin cap body 1. The design that the disinfection sponge 402 has the same size as the heparin cap body 1 can make the disinfection effect concentrated on the input end, avoid the contact of the disinfection sponge 402 with the areas that do not need to be disinfected, improve the accuracy and effectiveness of disinfection, and eliminate potential pathogens and pollutants to the greatest extent.
[0035] Preferably, auxiliary rings 7 are provided at the open end of the inner tube 2 and at the end of the outer tube 6 away from the open end. Anti-slip lines are provided on both of the auxiliary rings 7. When the push rod 403 needs to be used, hold the two auxiliary rings 7 with both hands respectively, and rotate the hand holding the auxiliary ring 7 on the outer tube 6. At the same time, the setting of the anti-slip lines can increase the friction between the auxiliary ring 7 and the hand, so as to facilitate rotating the outer tube 6 to drive the push rod 403 to push or pull outwards
[0036] Working principle and usage process of the present utility model: When using this device, the heparin cap body 1 is pushed into the inner tube 2 from the open end of the inner tube 2. At the same time, the heparin cap body 1 squeezes the deformation ring 3, and the deformation ring 3 deforms. When the heparin cap body 1 completely enters the inner tube 2 and abuts against the stop ring 5, stop pushing the heparin cap body 1. At this time, the deformation ring 3 restores its deformation and squeezes the heparin cap body 1 to fix the heparin cap body 1 by extrusion. At the same time, the input end of the heparin cap body 1 contacts the disinfection sponge 402, and the disinfectant in the liquid storage cavity 401 continuously disinfects the heparin cap body 1 through the disinfection sponge 402. When it is necessary to inject medicine through the heparin cap body 1, hold the auxiliary ring 7 on the outer tube 6 and the auxiliary ring 7 on the inner tube 2 with both hands respectively, and rotate the auxiliary ring 7 on the outer tube 6. When the outer tube 6 moves towards the open end of the inner tube 2, it drives the push rod 403 to push the liquid storage cavity 401. At this time, the liquid storage cavity 401 pushes the heparin cap body 1 to squeeze the deformation ring 3 and leave the inner tube 2, and then the disinfected heparin cap body 1 can be directly used. After use, fix the heparin cap body 1 in the inner tube 2 and then disinfect it for the next use. Repeat this process until the disinfectant in the liquid storage cavity 401 is used up. When in use, the heparin cap is completely wrapped therein to protect the heparin cap and disinfect the heparin cap at the same time, avoiding the need for medical staff to disinfect each operation and reducing the work burden of medical staff.
