Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a heating device for a urine-powered perfusion tube. Background Art

[0002] Urodynamics is a branch of urology. It mainly detects the pressure, flow rate and bioelectric activity of various parts of the urinary tract based on the basic principles and methods of urine fluid mechanics and electrophysiology. The urodynamics instrument mainly studies the data during urine storage and urination to study the condition. During the test, the infusion tube is inserted into the urinary tract. After connecting with the urinary tract of the subject, the test liquid is infused into the bladder through the infusion tube. The urodynamic analyzer monitors the data of the liquid in the bladder to evaluate whether there is bladder dysfunction.

[0003] In actual clinical operations, normal saline is often used as the test liquid. However, due to the low temperature of saline, which is greatly different from the temperature in the subject's bladder, the low-temperature normal saline will stimulate the bladder after entering the bladder. As a result, after a small amount of test liquid enters the bladder, it will cause the subject to have a urge to urinate, thus affecting the normal progress of the urodynamic examination. The temperature of the test liquid greatly affects the accuracy of the examination.

[0004] In addition, the distance between the examination instrument and the examinee is large. Due to gravity, the perfusion tube is easily dragged on the ground, affecting the hygiene of the perfusion tube. At present, the urodynamic examination takes half an hour, and the perfusion tube may shake, affecting the stability of the connection between the perfusion tube and the patient.

[0033] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0034] See also Figures 1 to 6 Understand this application.

[0035] See also Figure 1 , Figure 2 , a urinary dynamic perfusion tube heating device, comprising: a heating tube 101, the heating tube 101 is formed with a working channel 104 allowing the perfusion tube to pass through along its axial direction; in one embodiment of the present application, the heating tube 101 comprises a first fixing member 102 and a second fixing member 103 pivotally connected to the first fixing member 102, the first fixing member 102 is pivotally connected to the second fixing member 103 through a first pivot shaft 501, the first fixing member 102 is provided with a first fixing portion, and the second fixing member 103 is provided with a second fixing portion; the first fixing member 102 can rotate relative to the second fixing member 103 in the plane where the cross section of the heating tube 101 is located, and move between a fixed position and an open position; when the first fixing member 102 is in the fixed position, the first fixing portion and the second fixing portion form the working channel 104; when the first fixing member 102 moves from the fixed position to the open position, the first fixing member 102 is separated from the second fixing member 103, and the side wall of the working channel 104 is opened.

[0036] See also Figure 2The first fixing part and the second fixing part are both grooves. When the first fixing part 102 is located at the fixed position, the first fixing part and the second fixing part form a working channel 104. When the first fixing part 102 rotates to the open position around the first pivot axis 501, the heating tube 101 is opened, and the perfusion tube can enter the working channel 104 through the side wall of the heating tube 101. Then the first fixing part 102 rotates to the fixed position around the first pivot axis 501, so that the side wall of the heating tube 101 is closed, and the inner wall of the working channel 104 can limit the movement of the perfusion tube, which restricts the movement of the perfusion tube and prevents the perfusion tube from falling to the ground. At the same time, the working channel 104 can provide a force to the perfusion tube to prevent the perfusion tube from being unstable in connection with the subject's urinary tract due to its own weight and the weight of the test liquid.

[0037] Of course, technicians in the technical field to which the present application belongs can understand that the first fixing portion in the present application can be a groove, the second fixing portion is not a groove, the perfusion tube can be placed in the first fixing portion, the second fixing portion is a plane, and when the first fixing member 102 is located at a fixed position relative to the second fixing member 103, the first fixing member 102 and the second fixing member 103 can work together to fix the perfusion tube. Similarly, the first fixing portion can be a plane, the second fixing portion can be a groove, the perfusion tube can be placed in the second fixing portion, and the first fixing member 102 and the second fixing member 103 can work together to fix the perfusion tube. Of course, the first fixing portion and the second fixing portion can also have other implementation methods, which will not be repeated here. The first fixing portion and the second fixing portion can form a working channel 104 to fix the perfusion tube.

[0038] See also Figure 2 , Figure 5 In one embodiment of the present application, the urodynamic perfusion tube heating device also includes a flexible friction strip 302, which extends along the working channel 104. Along the circumference of the working channel 104, the urodynamic perfusion tube heating device array is provided with a plurality of flexible friction strips 302, and the flexible friction strip 302 can be in the form of a sheet and can be deformed. The flexible friction strip 302 is made of materials such as rubber and silicone, and has a large friction coefficient with the perfusion tube. Therefore, when the plurality of flexible friction strips 302 rub against the perfusion tube passing through the working channel 104, the plurality of flexible friction strips 302 can limit the movement of the perfusion tube. At the same time, due to the flexibility of the flexible friction strip 302, it can be greatly deformed and fit on the wall of the perfusion tube, thereby increasing the contact area with the perfusion tube, so that when the pressure between the two is small, a large friction force can be generated to limit the movement of the perfusion tube, and at the same time, excessive squeezing of the perfusion tube can be avoided, resulting in inaccurate test results of the urodynamic analyzer.

[0039] For further information, see Figure 2 , Figure 6The urodynamic perfusion tube heating device includes two heating tubes 101 pivotally connected to each other, and the two heating tubes 101 are connected by a second pivot shaft 502. One heating tube 101 can rotate relative to the other heating tube 101, so that the relative angle between the two heating tubes 101 can be adjusted as needed, thereby achieving different bending angles of the perfusion tube to avoid the space required for the doctor's operation. The angle between the two heating tubes 101 can also be adjusted according to the relative positions of the urodynamic analyzer and the patient; while adjusting the angle, the two heating tubes 101 fix the perfusion tube to prevent the perfusion tube from shaking at will, resulting in an unstable connection between the perfusion tube and the patient's urinary tract, which affects the doctor or the examinee.

[0040] Preferably, when the two heating tubes 101 are in a horizontal position, the two heating tubes 101 can rotate relative to each other around the second pivot axis 502, so that one heating tube 101 can rotate relative to the other heating tube 101 in a horizontal plane, thereby adjusting the direction of the perfusion tube according to the relative position between the urodynamic analyzer and the patient, and the two heating tubes 101 can fix the perfusion tube to prevent the perfusion tube from pulling the connection between the perfusion tube and the urinary tract due to its own gravity and the gravity of the test liquid.

[0041] See also Figures 1 to 3 The urine dynamic perfusion tube also includes an adjustment bracket, which is connected to the heating tube 101 and can adjust the spatial position and / or spatial posture of the heating tube 101.

[0042] In one embodiment of the present application, the adjustment bracket includes a base 203 and a first connecting rod 201, one end of the first connecting rod 201 is connected to the base 203, and the other end is connected to the heating tube 101 through a ball hinge structure 401. Furthermore, the adjustment bracket also includes a second connecting rod 202, the first connecting rod 201 is connected to the base 203 through the second connecting rod 202, and the first connecting rod 201 is connected to the second connecting rod 202 through the ball hinge structure 401.

[0043] The first connecting rod 201 is connected to the heating tube 101 through a ball hinge structure 401, and the second connecting rod 202 is connected to the first connecting rod 201 through a ball hinge structure 401, so that the two ball hinge structures 401 can be adjusted as needed to adjust the position of the heating tube 101, and the heating tube 101 fixes the perfusion tube in a suitable position.

[0044] When two heating tubes 101 are provided in the present application, the first connecting rod 201 is connected to one of the heating tubes 101 via a ball hinge structure 401, thereby cooperating with the pivot connection structure between the two ball hinge structures 401 and the two heating tubes 101, so that the heating tube 101 can have more posture changes, and the posture and bending conditions of the perfusion tube can have more changes.

[0045] Of course, technicians in the technical field to which the present application belongs can understand that the present application can only set the first connecting rod 201, the base 203 is directly connected to the heating tube 101 through the first connecting rod 201, and the first connecting rod 201 is connected to the heating tube 101 through the ball hinge structure 401, so that the heating tube 101 can rotate relative to the first connecting rod 201 through the ball hinge structure 401, or tilt at different angles to adjust the posture of the heating tube 101.

[0046] In one embodiment of the present application, see Figure 4 The ball hinge structure 401 includes a ball seat 402 , and a ball socket 403 of the ball seat 402 is provided with an anti-skid layer. The anti-skid layer can be made of materials such as rubber and silicone to increase the friction between the ball seat 402 and the ball socket 403 and limit the rotation of the ball head 406 .

[0047] See also Figure 4 In one embodiment of the present application, the ball hinge structure 401 includes a ball seat 402 and a ball head 406; the ball seat 402 includes two petals 405, and the two petals 405 form a ball socket 403 connected to the ball head 406; one of the petals 405 is connected to a locking bolt 404, and the locking bolt 404 can rotate around its own axis, and the other petal 405 is provided with a locking threaded hole matched with the locking bolt 404. When the locking bolt 404 rotates, the distance between the two petals 405 can be reduced, and the two petals 405 are pulled closer. Under the action of the locking bolt 404, the two petals 405 squeeze the ball head 406 entering the ball socket 403. The ball head 406 entering the ball socket 403 is squeezed by the two petals 405, so that the pressure between the petal 405 and the ball head 406 increases, thereby increasing the friction between the ball head 406 and the ball socket 403, so that the ball socket 403 fixes the ball head 406 and limits the rotation of the ball head 406.

[0048] Technicians in the technical field described in the present application can understand that, in the ball hinge structure 401 connecting the first connecting rod 201 and the second connecting rod 202, the first connecting rod 201 can be connected to the ball head 406, and the second connecting rod 202 can be connected to the ball seat 402, or, the first connecting rod 201 is connected to the ball seat 402, and the second connecting rod 202 is connected to the ball head 406; in the ball hinge structure 401 connecting the first connecting rod 201 and the heating tube 101, the first connecting rod 201 can be connected to the ball head 406, and the heating tube 101 can be connected to the ball seat 402, or, the first connecting rod 201 is connected to the ball seat 402, and the heating tube 101 is connected to the ball head 406.

[0049] The urodynamic perfusion tube heating device also includes a heating unit, which is connected to the working channel 104 and can heat the working channel 104; in one embodiment of the present application, the heating unit is a heating plate 301, which is arranged in the working channel 104, and the extension direction of the heating plate 301 is the same as the axial direction of the working channel 104, see Figure 2 , Figure 5 The heating plate 301 extends along the working channel 104. The heating plate 301 is an electric heating plate. When powered on, the heating plate 301 can heat the perfusion tube in the working channel 104, so that the test liquid passing through the working channel 104 rises to a temperature suitable for testing, thereby reducing the stimulation of the test liquid to the bladder and improving the accuracy of the data. Of course, the heating plate 301 can also heat the circulating fluid to heat the perfusion tube in the working channel 104.

[0050] See also Figure 2 In one embodiment of the present application, the urodynamic perfusion tube heating device includes at least two heating plates 301, and the two heating plates 301 are respectively connected to the first fixing member 102 and the second fixing member 103, so that the two heating plates 301 can perform all-round heating on the perfusion tube placed in the working channel 104.
