Description

Technical Field

[0001] The utility model belongs to the technical field of medical care equipment, and particularly relates to a blood dialysis pipeline clip structure. Background Technique

[0002] Blood dialysis pipeline clips are usually used in dialysis treatment to control blood flow and pipelines during the treatment process. In dialysis treatment, the reasonable use of pipeline clips can ensure the safety and effectiveness of the treatment. Blood dialysis pipeline clips are used to clamp the pipeline when it is necessary to temporarily interrupt blood flow, such as in the case of replacing the perfusion device or the dialyzer when the perfusion device or the dialyzer is blocked during the dialysis plus perfusion process. When it is necessary to interrupt blood flow, the operator will stop the blood flow by clamping the pipeline clip on the pipeline. In dialysis treatment, the operator usually undergoes special training to understand how to correctly use the pipeline clip to ensure the safety of patients. When using the pipeline clip, it is necessary to ensure that the clamping force is moderate, not too tight or too loose, so as not to affect blood flow or cause damage to the pipeline. In addition, attention should be paid to the clamping position and method to ensure that the clamped position is correct and does not damage the pipeline. Regularly check the status of the pipeline clip to ensure the normal function of the clamp. Regularly clean the pipeline clip to avoid bacterial growth and affect the use effect. A hemostatic forceps is a medical tool used to clamp the blood circuit tube and control blood flow for other operations during dialysis.

[0003] During hemodialysis, the hemostatic forceps may be used in the following situations: for the operation of the perfusion device. During the dialysis plus perfusion treatment, since the perfusion treatment ends after two hours and the dialysis treatment still needs to continue, it is necessary to remove the perfusion device from the dialysis pipeline midway. The hemostatic forceps are needed to clamp the blood circuit tubes at both ends of the perfusion device to avoid blood leakage. When replacing the dialyzer, when the dialyzer is blocked during dialysis, it is necessary to replace the dialyzer midway. During this process, the hemostatic forceps can be used to control the blood in the blood circuit tube and keep the operation area clean. However, the current hemostatic forceps are relatively heavy, and it is not easy for medical staff to give full play to the role of the hemostatic forceps when they are extremely tired. Therefore, a pipeline clip is needed to replace the hemostatic forceps for operation. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a blood dialysis pipeline clip structure to solve the technical problems that the hemostatic forceps are relatively heavy and inconvenient to use mentioned in the above background.

[0006] (2) Technical Solution

[0007] To solve the above technical problems, the utility model provides such a blood dialysis pipeline clip structure, which includes a clip body. An extended squeezing rod is arranged at the top of the clip body. A finger belly groove is arranged inside the extended squeezing rod. A reserved groove is arranged in the middle of the inner side of the clip body;

[0008] An embedded groove is provided at the upper end of the inner side of the clip body. An internal spring is provided inside the embedded groove. A replaceable double-layer spring is provided at the low end inside the embedded groove. An auxiliary structure is provided at the middle of the outer side of the clip body.

[0009] Furthermore, the length of the extended pinch bar is 1.5 times the length of a normal clip, increasing the torque of the extended pinch bar and reducing the force applied to the extended pinch bar.

[0010] Furthermore, the length of the replaceable double-layer spring is less than that of the internal spring, and there is only a storage relationship between the replaceable double-layer spring and the inner side of the embedded groove, facilitating the placement of the replaceable double-layer spring deep inside the embedded groove and also facilitating the replacement between the internal spring and the replaceable double-layer spring by medical staff.

[0011] Furthermore, the elastic coefficient of the internal spring is greater than the elastic coefficient of a single layer of the replaceable double-layer spring, facilitating the matching of the elastic coefficient of the double-layer cross structure of the replaceable double-layer spring with the elastic coefficient of the internal spring.

[0012] Furthermore, the auxiliary structure includes a push-pull rod, a telescopic rod, an internal ring, and an outer cylinder. One end at the middle of the outer side of the clip body is provided with an outer cylinder. One end inside the said outer cylinder is provided with a push-pull rod. The other end inside the outer cylinder is provided with a telescopic rod. One end of the telescopic rod is connected with an internal ring. A spring is provided inside the outer cylinder, facilitating a buffering force when the push-pull rod is pulled backward, so that medical staff will not separate the push-pull rod from the outer cylinder during extreme fatigue.

[0013] Furthermore, the telescopic rod and the internal ring are fixedly connected to prevent the internal ring from falling off.

[0014] Furthermore, the diameter of the push-pull rod is the same as the diameter of the telescopic rod, facilitating the push-pull rod to drive the telescopic rod to move backward.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. When medical staff use the clip body to clamp the pipeline of the dialysis instrument, pull the push-pull rod backward. The push-pull rod moves in cooperation with the outer cylinder. At this time, the push-pull rod drives the telescopic rod to move backward with the spring inside the outer cylinder, and the telescopic rod drives the internal ring to snap into the inner side of the reserved groove, thereby increasing the opening time of the reserved groove and providing sufficient reaction time for medical staff;

[0018] 2. By adjusting the length of the extended pinch rod and replacing different spring components, the force and clamping strength of the clamping instrument can be adjusted to meet the needs of medical staff during actual operation. By extending or shortening the length of the extended pinch rod, the force of the clamping instrument can be adjusted, enabling medical staff to easily control the clamping instrument and improving the convenience and comfort of operation.

[0019] 3. Replacing with a replaceable double-layer spring with a smaller spring coefficient can make medical staff feel more relaxed when using the clamping instrument, reduce the consumption of strength, and improve work efficiency.

[0020] 4. The design of the push-pull rod, outer cylinder, and telescopic rod enables the clamping instrument to have a longer opening time when clamping the pipeline, providing sufficient reaction time for medical staff, effectively avoiding misoperation or accidents, and improving the safety of operation.

[0021] 5. By adjusting the structure of each component and the selection of springs, this clamping instrument can provide better hand feeling, control, and safety for medical staff during actual operation, thereby improving the efficiency and accuracy of operation. Description of the Drawings

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a blood dialysis tubing clamp structure, including a clamp body 1, a lengthened pinch lever 2 is arranged at the top of the clamp body 1, a finger belly groove 3 is arranged inside the lengthened pinch lever 2, and a reserved groove 5 is arranged at the middle part inside the clamp body 1;

[0031] An embedded groove 8 is arranged at the upper end inside the clamp body 1, a built-in spring 7 is arranged inside the embedded groove 8, a replaceable double-layer spring 4 is arranged at the low end inside the embedded groove 8, and an auxiliary structure 6 is arranged at the middle part outside the clamp body 1.

[0032] The auxiliary structure 6 includes a push-pull rod 601, a telescopic rod 602, a built-in ring 603 and an outer cylinder 604. An outer cylinder 604 is arranged at one end of the middle part outside the clamp body 1. A push-pull rod 601 is arranged at one end inside the said outer cylinder 604, a telescopic rod 602 is arranged at the other end inside the outer cylinder 604, one end of the telescopic rod 602 is connected to a built-in ring 603, and a spring is arranged inside the outer cylinder 604. According to the description you provided, the auxiliary structure 6 includes a push-pull rod 601, a telescopic rod 602, a built-in ring 603 and an outer cylinder 604. An outer cylinder 604 is arranged at one end of the middle part outside the said clamp body 1, a push-pull rod 601 is arranged at one end inside the said outer cylinder 604, a telescopic rod 602 is arranged at the other end inside the said outer cylinder 604, one end of the said telescopic rod 602 is connected to a built-in ring 603, and a spring is arranged inside the said outer cylinder 604. The following effects can be produced:

[0033] The position setting of the push-pull rod 601 through the outer cylinder 604 can provide the force and direction of pushing and pulling during operation to help the clamping instrument perform the clamping operation. The telescopic rod 602 is connected to the built-in ring 603. When the push-pull rod 601 pushes the outer cylinder 604, the telescopic rod 602 will drive the built-in ring 603 to move accordingly, thereby adjusting the opening and clamping states of the clamping instrument. A spring is arranged inside the cylinder 604. The function of this spring may be to provide a resilience force and stability, so that the clamping instrument has appropriate elasticity and stability during operation. The design of this auxiliary structure can help medical staff more conveniently control the operation of the clamping instrument. Through the cooperation of the push-pull rod, the telescopic rod and the built-in ring, the clamping and loosening of the clamping instrument are realized, improving the accuracy and convenience of the operation. At the same time, the setting of the spring also helps to maintain the stability and operation feeling of the clamping instrument.

[0034] Working principle: As Figures 1-6 shown, when using this blood dialysis tubing clamp structure, first, medical staff pinch the lengthened pinch rod 2. The length of the lengthened pinch rod 2 is increased. Then, put the thumb and index finger into the finger belly groove 3. When pressing the lengthened pinch rod 2, the clamp body 1 opens to both sides driven by the built-in spring 7 and the lengthened pinch rod 2. And the reserved groove 5 provides a groove for the outside of the tubing to be embedded. If the medical staff is not sure about the situation of the dialysis equipment tubing, pull the push rod 601 backward. At this time, the spring and the telescopic rod 602 inside the outer cylinder 604 move backward following the push rod 601. And the telescopic rod 602 drives the built-in ring 603 to snap into the inner side of the reserved groove 5. At this time, the clamp body 1 and the reserved groove 5 will maintain an open angle and will last for a period of time. This provides the medical staff with corresponding reaction time. At the same time, when the medical staff finds during the daily inspection that the elastic coefficient of the built-in spring 7 is too large and causes the clamp body 1 to be not easy to open, remove the built-in spring 7, and then snap the replaceable double-layer spring 4 into the embedded groove 8 at the upper end of the inner side of the clamp body 1. At this time, the elastic coefficient of the replaceable double-layer spring 4 is half of that of the built-in spring 7, and the number of the replaceable double-layer springs 4 is twice that of the built-in spring 7. At the same time, the special cross structure of the replaceable double-layer spring 4 improves the stability during use, thus reducing unnecessary force for the medical staff. This is the characteristic of this blood dialysis tubing clamp structure.
