Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a pipeline metering and fixing device for automatic peritoneal dialysis drainage. Background Technique

[0002] Automatic peritoneal dialysis is a method of treating kidney failure by filtering waste through the peritoneum. This method injects dialysate into the peritoneal cavity, uses the peritoneal wall and blood for material exchange, and removes waste and excess water from the body. Implanting a dialysis tube in the patient's abdomen simplifies the dialysis process and reduces the impact of dialysis on the physical and mental health of the patient.

[0003] The meter is mainly used to detect the flow rate in the dialysis pipeline, so as to evaluate the performance of the dialyzer. The dialyzer plays a key role in the process of hemodialysis, and its performance directly affects the effect of dialysis treatment and the life safety of patients. Therefore, the accuracy and reliability of the dialyzer pump tube flow tester are crucial for ensuring the quality of dialysis treatment and the health of patients. The common connection method between the pipeline and the meter is the direct plug-in type.

[0004] Since the outer diameter of the joint of the common meter is slightly larger than the inner diameter of the pipeline, the inner diameter of the pipeline is squeezed by the joint, causing the pipeline connection to deform. Under the action of the self-recovery ability of the pipeline itself, the pipeline and the joint can be connected together; therefore, the pipeline and the joint can be connected by direct plugging. However, it is precisely because the outer diameter of the joint is slightly larger than the inner diameter of the pipeline that the connection process is relatively difficult, and after a long time of connection, the self-recovery ability of the pipeline will gradually decrease, making the connection unstable.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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.

[0034] Please refer to Figures 1 to 8 , as an embodiment of the present utility model, the pipeline metering and fixing device for automated peritoneal dialysis drainage includes two symmetrically arranged first fixing plates 1, and a second fixing plate 2 is rotatably installed on the first fixing plate 1;

[0035] The first fixing plate 1 and the second fixing plate 2 are provided with a first fixing structure and a second fixing structure, and the first fixing structure and the second fixing structure cooperate with each other to clamp and fix the conduit 6;

[0036] The two first fixing plates 1 are connected by a docking structure, and the docking structure can drive the two first fixing plates 1 to approach each other, so as to drive the conduit 6 to approach the metering instrument 7 to complete the docking;

[0037] A buffer structure is arranged on the first fixing plate 1, and a slider 3 is connected to the buffer structure. When the conduit 6 is tensioned, the buffer structure can be driven to act through the slider 3.

[0038] In this embodiment, first rotate the second fixing plate 2 to separate it from the first fixing plate 1, and then embed the conduit 6 into the first fixing mechanism. At this time, the buffer structure will drive the slider 3 to move towards the conduit 6, so that the slider 3 abuts against the conduit 6 and makes part of the conduit 6 in a bent state in the first fixing structure; then rotate the second fixing plate 2 to make it abut against the first fixing plate 1. During the rotation process, the conduit 6 will also be embedded into the second fixing structure. Through the mutual extrusion of the first fixing structure and the second fixing structure, the end of the conduit 6 close to the metering instrument 7 will be firmly fixed, and there is a bendable part between the first fixing plate 1 and the second fixing plate 2; when an external force is applied to the conduit 6 to stretch it in the direction away from the metering instrument 7, the conduit 6 will drive the buffer structure to act through the slider 3. Through the buffering of the buffer structure, the difficulty of straightening the conduit 6 can be increased, and after the external force is removed, the buffer structure can drive the conduit 6 to reset.

[0039] After the catheter 6 is fixed to the first fixing plate 1 and the second fixing plate 2, the two first fixing plates 1 are driven to approach each other at the same time through the docking structure, thereby driving the end of the catheter 6 to gradually approach the interface of the meter 7, and in the process of approaching, the catheter 6 will be docked with the interface of the meter 7, and the docking structure will maintain the stable connection between the catheter 6 and the meter 7 after the docking is completed.

[0040] The mutual interference between the first fixing structure and the second fixing structure can fix the catheter 6 so that it cannot be easily separated from the first fixing plate 1, and under the buffering effect of the buffer structure, the pulling force applied to the catheter 6 makes it more difficult to separate the catheter 6 from the first fixing plate 1, so as to prevent external interference factors from pulling the catheter 6 to make it detach from the meter 7 and affect the dialysis effect; the docking process becomes simpler through the docking structure, which can save manpower, and the docking structure also has the ability to limit the detachment of the catheter 6 from the meter 7, effectively improving the success rate of dialysis.

[0041] As a further solution of the utility model, the first fixing structure includes a first guide opening 101 opened on one side of the first fixing plate 1 away from the other first fixing plate 1; a second guide opening 102 is opened on the other side thereof, and a first chamber 104 connecting the first guide opening 101 and the second guide opening 102 is opened on the first fixing plate 1; and a plurality of first arc-shaped protrusions 103 are installed on the second guide opening 102.

[0042] As a further solution of the utility model, the second fixing structure includes a third guide opening 201 opened on one side of the second fixing plate 2 away from the other second fixing plate 2; a fourth guide opening 202 is opened on the other side thereof, and a second chamber 204 connecting the third guide opening 201 and the fourth guide opening 202 is opened on the second fixing plate 2; and a plurality of second arc-shaped protrusions 203 are installed on the fourth guide opening 202.

[0043] In this embodiment, when the end of the conduit 6 that is connected to the meter 7 is inserted into the first guide port 101, due to the restriction of the first arc-shaped protrusion 103, the part of the conduit 6 that contacts the first arc-shaped protrusion 103 will be deformed, so that the difficulty of the conduit 6 moving along the wall of the conduit 6 increases; when the conduit 6 is placed in the second guide port 102; the width of the first chamber 104 is much larger than the diameter of the conduit 6. Therefore, the conduit 6 can bend freely in the first chamber 104; when bending, the conduit 6 will slide from the second guide port 102 into the first chamber 104.

[0044] When the second fixing plate 2 and the first fixing plate 1 are rotated and closed, the third guide opening 201 will contact the conduit 6, and the second arc-shaped protrusion 203 will also cause the conduit 6 to deform, so that the difficulty of the conduit 6 moving along the wall direction of the conduit 6 is further increased, and the fourth guide opening 202 will also slide in contact with the conduit 6; the conduit 6 will enter the second chamber 204, and the conduit 6 can bend in the second chamber 204; when bending, the conduit 6 will slide from the fourth guide opening 202 into the second chamber 204.

[0045] The mutual interference between the first fixing structure and the second fixing structure can fix the conduit 6 so that it cannot be easily separated from the first fixing plate 1 , thereby improving the stability of the connection between the conduit 6 and the meter 7 .

[0046] As a further solution of the utility model, the docking structure includes an internally threaded telescopic column 4 installed on one of the first fixed plates 1, and a telescopic sleeve 5 connected to the other first fixed plate 1 is slidably engaged on the internally threaded telescopic column 4; a screw column 401 threadedly connected to the internally threaded telescopic column 4 is rotatably installed on the telescopic sleeve 5.

[0047] In this embodiment, the screw column 401 is rotated to drive the internal thread telescopic column 4 to slide inward in the telescopic sleeve 5 through threaded engagement, thereby driving the two first fixed plates 1 to approach each other, driving the catheter 6 to approach the interface of the meter 7, and completing the docking.

[0048] The diameter of the connector of the common meter 7 is slightly larger than the inner diameter of the catheter 6 to increase the stability of the connection between the catheter 6 and the connector; at the same time, it also increases the difficulty of docking.

[0049] The connection between the catheter 6 and the connector is completed by threaded cooperation between the screw column 401 and the internally threaded telescopic column 4, which can save manpower and reduce the difficulty of connection; because after the screw column 401 stops rotating, the position of the internally threaded telescopic column 4 will be locked, so that the connection between the catheter 6 and the connector becomes more stable, thereby improving the success rate of dialysis.

[0050] As a further solution of the utility model, the buffer structure includes a first slide groove 105 opened on the first fixed plate 1 and connected to the first chamber 104; and a second slide groove 205 opened on the second fixed plate 2 and connected to the second chamber 204; a slider 3 that can slide with the second slide groove 205 is slidably engaged on the first slide groove 105, and a spring 301 connected to the first slide groove 105 is installed on the slider 3.

[0051] In this embodiment, the portion of the catheter 6 located within the first chamber 104 will come into contact with the slider 3, and the slider 3, under the elastic force of the spring 301, will be at the end of the first chute 105 close to the first chamber 104, and a portion of the slider 3 is located within the first chamber 104, thereby squeezing the catheter 6 and causing it to bend, such that the length of the catheter 6 located within the first fixing plate 1 is greater than the width of the first fixing plate 1.

[0052] When an external force is applied to the catheter 6 to stretch it along its length direction, the bent catheter 6 will be straightened at the positions of the second guide port 102 and the fourth guide port 202; the straightened and bent catheter 6 will squeeze the slider 3 to displace, causing the slider 3 to slide inwardly within the first chute 105 and the second chute 205, and the spring 301 will be gradually compressed. As the compression amount of the spring 301 increases, its elastic force will also increase, thereby causing the resistance during the straightening process of the catheter 6 to increase, such that the external force will not easily pull out the catheter 6 from the first fixing plate 1. This is to prevent external interference factors from pulling the catheter 6 to disengage it from the meter 7, thereby affecting the dialysis effect.

[0053] As a further solution of the present utility model, a connecting post 207 is installed on the second fixing plate 2, a contraction slit 208 is provided on the connecting post 207, and a fitting groove 106 for engaging with the connecting post 207 is provided on the first fixing plate 1.

[0054] In this embodiment, during the process of the second fixing plate 2 rotating closer to the first fixing plate 1, the connecting post 207 will come into contact and cooperate with the fitting groove 106. Since the diameter of the connecting post 207 is slightly larger than the diameter of the fitting groove 106, the fitting groove 106 will squeeze the connecting post 207, causing the distance between the contraction slits 208 to become smaller, so that the connecting post 207 can enter the fitting groove 106, and under the elastic force of the connecting post 207, it will be in close fit with the fitting groove 106.

[0055] As a further solution of the present utility model, an observation groove 206 for observing the catheter 6 is provided on the second fixing plate 2.

[0056] In this embodiment, the deformation amount of the catheter 6 located within the first chamber 104 and the second chamber 204 is observed through the observation groove 206 to avoid damage to the catheter 6 when it is straightened due to excessive external force.

[0057] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included within the present utility model.
