TECHNICAL FIELD
[0001] The utility model relates to the technical field of abdominal puncture, more particularly to an anti-falling device for abdominal puncture tube placement and drainage. BACKGROUND
[0002] Abdominal puncture is a technique for assisting in diagnosis and treatment of diseases by directly puncturing the peritoneal cavity from the anterior abdominal wall with a puncture needle or a catheter to extract ascites. In the prior art, abdominal puncture tube drainage tubes are generally adhered to the surface of the belly with adhesive tape. When the patient's ascites gradually decreases, the belly will become loose, and the adhesive tape is prone to falling off the patient's belly, resulting in the inability to continue abdominal drainage and the risk of dangerous phenomena.
[0003] The utility model with the authorization announcement number CN221084395U provides an anti-falling structure for abdominal puncture tube placement and drainage. The support mechanism is fixed on the waist and abdomen of the patient by the cooperation of the left connecting belt and the right connecting belt, which can solve the problem that the existing drainage tubes are generally adhered to the surface of the belly with adhesive tape, and when the ascites gradually decreases, the belly becomes loose and is prone to falling off, resulting in the inability to continue abdominal drainage and the risk of dangerous phenomena.
[0004] In the above-mentioned patent, the groove is provided on the lower fixed clamp for placing the drainage tube. After the medical staff places the drainage tube inside the groove, they need to turn the upper fixed clamp with one hand, so that the upper fixed clamp cooperates with the lower fixed clamp to fix the drainage tube. Since the drainage tube is a soft tube that is difficult to control the position, the medical staff needs to press the drainage tube inside the groove with the fingers of the other hand during the process of turning the upper fixed clamp. The fingers need to be removed from the drainage tube before the upper fixed clamp and the lower fixed clamp are completely closed. However, at the moment when the fingers of the medical staff are separated from the drainage tube, part of the drainage tube is prone to move out of the groove under the action of the elastic force, so that the upper fixed clamp and the lower fixed clamp press the local part of the drainage tube when they are closed, causing the tube wall of the drainage tube to be squeezed and bruised, affecting the drainage effect of the drainage tube. At the same time, in the above-mentioned patent, the medical staff pushes the pushing column towards the patient's waist and abdomen to release the compression and fixation of the movable plate on the connecting belt, so as to adjust the length of the connecting belt around the patient's waist and abdomen. However, the volume of the pushing column is small, and it is inconvenient for the medical staff to move the pushing column. At the same time, when the medical staff pushes the pushing column towards the patient's waist and abdomen, the hands of the medical staff are prone to press the abdomen of the patient, which causes harm to the abdominal drainage treatment of the patient.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT
[0029] Please refer to Figures 1-6The purpose of the embodiment is to provide a device for preventing the falling of a peritoneal puncture tube drainage tube. The device comprises a positioning mechanism 1 and a connecting belt 2. The positioning mechanism 1 comprises a U-shaped shell 11. One end of the connecting belt 2 is fixedly arranged at a position close to the bottom end of one side of the U-shaped shell 11. A medical adhesive tape 14 is fixedly connected to the lower side wall of the U-shaped shell 11. Medical staff can paste the U-shaped shell 11 on the abdomen of a patient through the medical adhesive tape 14, so as to preliminarily fix the U-shaped shell 11. A rotating roller 4 is rotatably arranged at a side of the U-shaped shell 11 away from the connecting belt 2 and the connecting position of the U-shaped shell 11. A gap is arranged between the rotating roller 4 and the U-shaped shell 11. A side groove 15 is arranged at a side of the U-shaped shell 11 close to the rotating roller 4. A clamping block 5 is slidably arranged in the side groove 15. One end of the clamping block 5 extends into the gap. An extension plate 51 is fixedly connected to a side of the clamping block 5 away from the gap. A plurality of second springs 52 are fixedly arranged between the other side of the extension plate 51 and the inner wall of the side groove 15 in a transverse array. The second springs 52 drive the extension plate 51 and the clamping block 5 to be close to the rotating roller 4. After the medical staff winds the connecting belt 2 around the waist and abdomen of the patient and passes the other end of the connecting belt 2 through the gap, the clamping block 5 and the rotating roller 4 are in contact with two sides of the connecting belt 2, respectively. At this time, the clamping block 5 and the rotating roller 4 cooperate to clamp and fix the connecting belt 2, so that the length of the connecting belt 2 around the waist and abdomen of the patient does not change. The U-shaped shell 11 is fixedly bound to the abdomen of the patient through the connecting belt 2, so as to secondarily fix the U-shaped shell 11. The drainage tube is fixed to the U-shaped shell 11, so as to avoid the problem that the drainage tube is separated from the abdomen of the patient during use, thereby ensuring the normal operation of abdominal drainage.
[0030] In order to fix the drainage tube in the interior of the U-shaped shell 11, a plurality of pre-positioning clamps 12 are arranged in a transverse array at a position in the middle of the upper side of the U-shaped shell 11. The pre-positioning clamp 12 comprises two elastic arc-shaped plates fixedly arranged on the inner bottom surface of the U-shaped shell 11. A U-shaped structure is surrounded by the side of the two elastic arc-shaped plates close to each other and the inner bottom surface of the U-shaped shell 11. After the medical staff clamps the drainage tube into the U-shaped structure of one of the pre-positioning clamps 12, the pre-positioning clamp 12 blocks the drainage tube from moving out of the interior of the U-shaped shell 11, so as to preliminarily position the drainage tube. Meanwhile, a cover plate 13 is hingedly arranged on the upper side wall of the U-shaped shell 11. The cover plate 13 is provided with a positioning assembly 3. After the drainage tube is clamped into the interior of one of the pre-positioning clamps 12, the medical staff rotates the cover plate 13. When the end of the cover plate 13 away from the hinging position of the cover plate 13 and the U-shaped shell 11 is in contact with the upper side wall of the U-shaped shell 11, the positioning assembly 3 fixes the position of the cover plate 13. At this time, the side of the cover plate 13 close to the U-shaped shell 11 is in contact with the top of the pre-positioning clamp 12 and the drainage tube. The cover plate 13 blocks the drainage tube from moving out of the interior of the U-shaped shell 11, so as to stably fix the drainage tube in the interior of the U-shaped shell 11, thereby avoiding the drainage tube from falling off the abdomen of the patient during abdominal drainage.
[0031] Meanwhile, the cover plate 13 is provided with a mounting groove 131, and the structure of the positioning assembly 3 is described as follows. The positioning assembly 3 comprises a movable plate 31 arranged in the mounting groove 131, a clamping hook 32 fixedly connected to one side of the movable plate 31 close to the bottom end, a plurality of slide rods 33 fixedly connected to the side of the movable plate 31 away from the clamping hook 32, a plurality of movable grooves 132 transversely arranged on the inner wall of the mounting groove 131, one end of each of the plurality of slide rods 33 being slidably arranged in one of the plurality of movable grooves 132, the slide rod 33 and the movable groove 132 being cooperatively arranged to limit the movement of the slide rod 33 to the axial direction of the slide rod 33, and a first spring 34 arranged in the movable groove 132 between the slide rod 33 and the inner wall of the movable groove 132, the first spring 34 being arranged to drive the movable plate 31 away from the movable groove 132. The inner wall of the U-shaped shell 11 is provided with a clamping groove 16, and one side of the clamping hook 32 is provided with a curved surface. When the medical staff rotates the cover plate 13 towards the U-shaped shell 11, the cover plate 13 drives the clamping hook 32 to rotate synchronously. When the curved surface of the rotating clamping hook 32 contacts the upper end of the inner wall of the U-shaped shell 11, the curved surface of the clamping hook 32 and the U-shaped shell 11 slide relative to each other, the U-shaped shell 11 drives the clamping hook 32 to move, the moving clamping hook 32 drives the movable plate 31 to move towards the movable groove 132 along the axial direction of the slide rod 33, and the first spring 34 is elastically contracted. When the end of the cover plate 13 away from the hinge between the cover plate 13 and the U-shaped shell 11 contacts the upper side wall of the U-shaped shell 11, one end of the clamping hook 32 is rotated to a position corresponding to the clamping groove 16. At this time, the first spring 34 is elastically recovered to drive the slide rod 33, the movable plate 31 and the clamping hook 32 to move, so that one end of the clamping hook 32 is clamped into the clamping groove 16. The position of the cover plate 13 on the U-shaped shell 11 is fixed by the cooperation of the clamping hook 32 and the clamping groove 16, so that the cover plate 13 blocks the drainage tube from being removed from the U-shaped shell 11, and the position of the drainage tube is fixed.
[0032] When the ascites of the patient gradually decreases due to continuous drainage, the waist circumference of the patient is also reduced synchronously. Although the connecting belt 2 has elasticity, when the waist circumference of the patient changes too much, the connecting belt 2 cannot automatically contract and bind on the waist and abdomen of the patient within the elastic range. The connecting belt 2 around the waist and abdomen of the patient cannot tightly contact the skin of the patient, which causes the fixing of the connecting belt 2 to the U-shaped shell 11 to fail, and the U-shaped shell 11 and the drainage tube fixed in the U-shaped shell 11 are prone to falling off from the abdomen of the patient. To solve this problem, the pressing assembly 6 is arranged at both ends of the rotating roller 4, and the pressing assembly 6 is arranged to drive the extension plate 51 away from the rotating roller 4. Meanwhile, the guide groove 41 is arranged at both ends of the rotating roller 4. The structure of the pressing assembly 6 is described as follows. Figure 5 and Figure 6When the connecting belt 2 wrapped around the waist and abdomen of the patient cannot be tightly attached to the skin of the patient, the medical staff synchronously presses the two pressing rods 61, so that the two pressing rods 61 are close to each other, the pressing rod 61 extrudes the third spring 62 in cooperation with the guide groove 41, and the third spring 62 is elastically contracted, in the process, the moving pressing rod 61 drives the abutting rod 63 to synchronously move, the extending plate 51 is provided with the wedge block 511 fixedly connected at both ends of the extending plate 51 and extending to the outside of the side groove 15, the side of the wedge block 511 close to the abutting rod 63 is provided as an inclined surface, and the end of the abutting rod 63 is in contact with the inclined surface of the wedge block 511, when the moving abutting rod 63 slides along the inclined surface of the wedge block 511, the abutting rod 63 pushes the wedge block 511 away from the pressing rod 61, the two moving wedge blocks 511 drive the extending plate 51 and the clamping block 5 to be away from the rotating roller 4, the second spring 52 is elastically contracted, the clamping block 5 and the rotating roller 4 release the clamping and fixing of the connecting belt 2, the medical staff pulls the connecting belt 2 away from the end of the U-shaped shell 11, adjusts the length of the connecting belt 2 wrapped around the waist and abdomen of the patient, and makes the connecting belt 2 tightly attached to the skin of the patient again, and then the medical staff releases the two pressing rods 61, the third spring 62 rebounds to push the pressing rod 61 and the abutting rod 63 to reset, the second spring 52 rebounds to push the extending plate 51, the wedge block 511 and the clamping block 5 to be close to the rotating roller 4, the wedge block 511 and the abutting rod 63 are kept in the state of sliding contact, and the clamping block 5 and the rotating roller 4 continue to clamp and fix the connecting belt 2 in cooperation, so that the fixing effect of the connecting belt 2 on the U-shaped shell 11 is ensured when the ascites of the patient is reduced, and the U-shaped shell 11 and the drainage tube fixed in the U-shaped shell 11 are prevented from falling off from the abdomen of the patient.
