Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of peritoneal dialysis, in particular to a medical clip for peritoneal dialysis. Background Art
[0002] Peritoneal dialysis clips are used during peritoneal dialysis, a type of dialysis that uses the body's own peritoneum as a dialysis membrane. Dialysis fluid infused into the peritoneal cavity exchanges solutes and water with plasma in the capillaries on the other side of the peritoneum, removing retained metabolic products and excess water from the body while simultaneously replenishing essential substances. By continuously renewing the peritoneal dialysis fluid, the goal of renal replacement or supportive therapy is achieved.
[0003] Currently, patients undergoing peritoneal dialysis receive training at a dialysis center and then perform the procedure at home. Patients undergoing peritoneal dialysis at home require careful attention to many precautions. The current schedule is 10 minutes for inflow and 20 minutes for outflow. However, some patients, due to fatigue, fall asleep after opening the dialysis fluid drain during peritoneal dialysis. Only upon awakening do they remember the drain, leading to over-drainage and inclusion of abdominal contents, which can block the peritoneal dialysis catheter and prevent smooth flow of peritoneal dialysis fluid. Some patients experience prolonged inflow and drainage times early on but fail to detect and seek medical attention, only presenting to the hospital after the tube becomes completely blocked. Blockage of the peritoneal dialysis tube prevents proper inflow and drainage. While some cases can be treated with thrombolytics, those who fail to respond to medication require surgical thrombolysis, which increases the pain. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a peritoneal dialysis medical clamp, which is easy to use and can not only clamp the infusion line or the drainage line, but also start the timer at the same time to remind the patient to check whether the infusion and drainage are completed, and to promptly discover that the infusion and drainage time is too long and prevent excessive drainage.
[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:
[0006] A peritoneal dialysis medical clamp comprises an expandable and closable V-shaped handle, the V-shaped handle having a left clamping handle and a right clamping handle, the first end of the left clamping handle and the first end of the right clamping handle forming an openable and closable connection, the second end of the left clamping handle is provided with a first clamping portion, and the second end of the right clamping handle is provided with a second clamping portion that is clamped with the first clamping portion; a first tube clamping portion is provided on the inner side of the left clamping handle, and a second tube clamping portion that cooperates with the first tube clamping portion is provided on the inner side of the right clamping handle, the first tube clamping portion is close to the first end of the left clamping handle, and the second tube clamping portion is close to the first end of the right clamping handle; it is characterized in that: it also includes a power supply, a first timer, a second timer, a first metal sheet and a second metal sheet, an electric wire is provided inside the V-shaped handle, and the first end of the electric wire is exposed on the inner side of the left clamping handle and close to the inner side of the right clamping handle. Near the second end of the left clamping handle, the second end of the wire is exposed on the inner side of the right clamping handle and close to the second end of the right clamping handle; the first metal sheet is installed on the inner side surface of the left clamping handle and connected to the first end of the wire, and the second metal sheet is installed on the inner side surface of the right clamping handle and connected to the second end of the wire; the power supply, the first timer, and the second timer are all installed on the V-shaped handle, and the first timer and the second timer are connected in parallel through the wire; when the left clamping handle and the right clamping handle are in the clamped state, the first metal sheet contacts the second metal sheet, and the first metal sheet, the power supply, the first timer, and the second metal sheet form a first circuit in sequence through the wire, and the first metal sheet, the power supply, the second timer, and the second metal sheet form a second circuit in sequence through the wire.
[0007] Under normal circumstances, when the patient does not hold the left clamp handle and the right clamp handle tightly, the first metal sheet and the second metal sheet are not in contact, so that the first circuit and the second circuit are not conductive. At this time, the hose carrying the dialysate is located between the first tube clamp part and the second tube clamp part, so that the dialysate can be smoothly injected into the patient's abdominal cavity and drained out. When the patient grips the left and right clamp handles with their hands, the first clamping portion engages with the second clamping portion, and the countdown time of the first timer and the second timer is set (the countdown time of the first timer can generally be set to be shorter than the countdown time of the second timer, for example, the countdown time of the first timer is set to 10 minutes, and the countdown time of the second timer is set to 20 minutes), the first tube clamp portion cooperates with the second tube clamp portion to fix and clamp the hose, blocking the dialysate in the hose from continuing to flow, and preventing unused peritoneal dialysis fluid from leaking into the drainage bag; at the same time, the first metal sheet contacts and cooperates with the second metal sheet, so that the first circuit and the second circuit are both in a conductive state. When the time set by the first timer expires, the first timer emits a first "beep" prompt sound to remind the patient to check whether the peritoneal dialysis fluid is infused and drained. When the time set by the second timer expires, the second timer emits a sharp and continuous "beep..." prompt sound to remind the patient, once again reminding the patient that the infusion and drainage have timed out.
[0008] In a preferred embodiment, a first mounting groove capable of accommodating the first metal sheet is provided on the inner side of the left clamping handle, with the notch of the first mounting groove facing inward. The outer half of the first metal sheet is mounted in the first mounting groove, while the inner half of the first metal sheet is exposed inside the first mounting groove. A second mounting groove capable of accommodating the second metal sheet is provided on the inner side of the right clamping handle, with the notch of the second mounting groove facing inward. The outer half of the second metal sheet is mounted in the second mounting groove, while the inner half of the second metal sheet is exposed inside the second mounting groove. Securing the metal sheets in the mounting grooves effectively prevents the metal sheets from loosening or falling off, thereby ensuring the stability of the circuit connection.
[0009] In a preferred embodiment, the left or right clamping handle is provided with a third mounting slot and a fourth mounting slot, with the first timer mounted in the third mounting slot and the second timer mounted in the fourth mounting slot. Securing the timers in the mounting slots effectively prevents them from loosening or falling off, ensuring their proper function, while also effectively utilizing the space in the left or right clamping handle, making the V-shaped handle more compact.
[0010] In a further preferred embodiment, the third mounting slot and the fourth mounting slot are arranged side by side, with the slot opening of the third mounting slot facing upward and the edge of the slot opening of the third mounting slot being covered by a first slot cover; the slot opening of the fourth mounting slot faces downward and the edge of the slot opening of the fourth mounting slot being covered by a second slot cover. The slot covers can cover the openings of the mounting slots, thereby protecting the timer from external impact, dust, or liquid intrusion, thereby extending the service life of the timer.
[0011] In a preferred embodiment, the first tube clamp portion includes a first semi-cylindrical cavity and a first semi-circular cut-off piece; the second tube clamp portion includes a second semi-cylindrical cavity and a second semi-circular cut-off piece; the first semi-cylindrical cavity and the second semi-cylindrical cavity are joined to form a cylindrical cavity for accommodating the hose; the first semi-circular cut-off piece is disposed within the first semi-cylindrical cavity, and the second semi-circular cut-off piece is disposed within the second semi-cylindrical cavity, with the diametrical edges of the first semi-circular cut-off piece correspondingly mating with the diametrical edges of the second semi-circular cut-off piece. When the first clamp portion and the second clamp portion are engaged, the diametrical edges of the first semi-circular cut-off piece and the second semi-circular cut-off piece align, clamping the hose and preventing the dialysate from continuing to flow within the hose.
[0012] In a preferred embodiment, the power source is a button battery.
[0013] In a preferred embodiment, the first clamping portion is a clamping slot, and the second clamping portion is a buckle. When the left clamping handle and the right clamping handle are in a clamped state, the buckle is in the clamping slot.

[0022] Under normal circumstances, when the patient does not hold the left clamp handle 11 and the right clamp handle 12 tightly, the first metal sheet 4 and the second metal sheet 5 are not in contact, so that the first circuit and the second circuit are not conductive. At this time, the hose carrying the dialysate is located between the first tube clamp portion 13 and the second tube clamp portion 14, so that the dialysate can be smoothly injected into the patient's abdominal cavity and drained out. When the patient grips the left clamp handle 11 and the right clamp handle 12, engaging the first clamp portion 111 with the second clamp portion 121, and setting the countdown times of the first timer 2 and the second timer 3 (generally, the countdown time of the first timer 2 can be set to be shorter than the countdown time of the second timer 3, for example, the countdown time of the first timer 2 can be set to 10 minutes and the countdown time of the second timer 3 can be set to 20 minutes), the first tube clamp portion 13 and the second tube clamp portion 14 can cooperate to securely clamp the flexible tube, blocking the continued flow of dialysate in the flexible tube and preventing unused peritoneal dialysis fluid from leaking into the drainage bag. At the same time, the first metal sheet 4 and the second metal sheet 5 contact and cooperate, so that both the first and second circuits are in a conductive state. When the time set for the first timer 2 expires, the first timer 2 emits a first "beep" alert sound to remind the patient to check whether the peritoneal dialysis fluid has been infused and drained. When the time set for the second timer 3 expires, the second timer 3 emits a sharp and continuous "beep..." alert sound to remind the patient again that the infusion and drainage have exceeded the time limit.
