[0026] The utility model provides a technical solution:
[0027] First, see Figure 1-Figure 3 A drainage tube holding device comprises a clamping device 1 and a moving device 2. The clamping device 1 has two groups. The two groups of clamping devices 1 are located on both sides of the surface of the moving device 2 and are fixedly connected. The distance between the two groups of clamping devices 1 is changed by the moving device 2. A card slot 201 is provided inside one side of the moving device 2. A moving plate is installed inside the card slot 201. A button block 202 is connected to the side of the moving plate away from the card slot 201. The side of the moving plate away from the card slot 201 and located on both sides of the button block 202 are connected to the card slot 202. The button block 202 and the buckle are used to fix one side of the fixing block 8. The button block 202 and the buckle pass through the card slot 201. A first spring is connected between the side of the movable plate away from the button block 202 and the card slot 201. When the user needs the clamping device 1 to clamp and fix the drainage tube, the buckle moves inward by pressing the button block 202 to open the clamping device 1. At this time, the button block 202 is released. The button block 202 and the buckle are automatically reset due to the resilience of the first spring, and the fixing block 8 can continue to be fixed.
[0028] For further information, see Figure 1-Figure 2The moving device 2 is used to adjust the distance between the clamping devices 1 on both sides. The moving device 2 includes a first moving block 3 and a second moving block 4 located inside the first moving block 3. The second moving block 4 is slidably connected to the inside of the first moving block 3, and the distance between the clamping devices 1 is controlled by sliding the second moving block 4 toward the inside of the first moving block 3. A first opening groove is provided on the surface of the first moving block 3 and the second moving block 4 and at a position away from the second moving block 4 and the first moving block 3 respectively. Two groups of second springs 6 are connected to the inner side of the first opening groove. The clamping plate 7 clamps drainage tubes of different thicknesses through the rebound force of the second spring 6. Pulleys are installed on both sides of the interior of the first moving block 3, and slide grooves 401 are provided at the positions corresponding to the pulleys on both sides of the second moving block 4. The pulleys and the slide grooves 401 make the second moving block 4 slide more smoothly when sliding inside the first moving block 3, making it more convenient and labor-saving to move.
[0029] For further information, see Figure 1-Figure 3 A third open groove is provided on the surface of the first moving block 3, and a fixing device 5 is installed inside the third open groove. A gear 301 is sleeved on the outer side of the fixing device 5, and a gear-shaped empty groove is provided in the center of the gear 301, so that the fixing rod 501 can fix the gear 301 so that the gear 301 cannot rotate. A rack 402 is connected to the surface of the second moving block 4, and the gear 301 is meshed with the rack 402. The second moving block 4 is moved by rotating the gear 301 to adjust the distance between the two sets of clamping devices 1.
[0030] The fixing device 5 is used to fix the gear 301 so that it does not rotate and to help the gear 301 rotate. The fixing device 5 includes a fixing rod 501 and a rotating rod 502 located inside the first moving block 3. One end of the fixing rod 501 and the rotating rod 502 are fixedly connected. The external structure of the fixing rod 501 is designed in the shape of a gear. The gear shape design matches the empty groove in the shape of the central gear of the gear 301. The fixing rod 501 is pushed into the center of the gear 301 so that the gear 301 cannot rotate. The fixing rod 501 and the rotating rod 502 are fixedly connected. The fixing rod 501 runs through both sides of the first moving block 3, and the end away from the first moving block 3 is connected to a pull handle. The outer side of the fixing rod 501 is sleeved with a third spring. The two ends of the third spring are fixedly connected to the pull handle and the first moving block 3. The pull handle is pulled to move the rotating rod 502 into the gear 301. At this time, the gear 301 can rotate. The pull handle is released and the fixing rod 501 is reset by the elastic force of the third spring. At this time, the fixing rod 501 enters the gear 301 and fixes the gear 301 so that the gear 301 cannot rotate.
[0031] Finally, see Figure 1-Figure 3The clamping device 1 is used to clamp and fix the drainage tube. The clamping device 1 includes a clamping plate 7 located at one end of the second spring 6 and a fixing block 8 located at one side of the moving device 2. One end of the two sets of second springs 6 away from the first opening groove is fixedly connected to the clamping plate 7. The clamping plate 7 is designed in a semicircular structure. The inner side of the fixing block 8 and the inner side of the clamping plate 7 are both bonded with rubber anti-skid pads. When clamping and fixing the drainage tube, the clamping plate 7 clamps the drainage tube due to the rebound force of the second spring 6, so that the drainage tube will not shake at will when moving. The fixing block 8 is designed in a concave structure. One side of the fixing block 8 is hingedly connected to the moving device 2. The hinge connection is convenient for opening the fixing block 8 to put in the drainage tube. The interior of the fixing block 8 is provided with a semicircular structure. The groove of the circular structure, the groove of the semicircular structure and the semicircular structure of the clamping plate 7 form a circle, which is more in line with the external shape of the drainage tube. A circular groove 801 is provided on one side of the fixing block 8, and buckle grooves are provided on both sides of the circular groove 801. The circular groove 801 and the buckle groove are respectively adapted and installed with the button block 202 and the buckle. When the buckle is embedded in the buckle groove, the fixing block 8 is in a closed state. The buckle is pressed into the inside of the buckle groove 201 by pressing the button block 202. At this time, the fixing block 8 is in an openable state. Then the button block 202 is released, and the buckle is reset due to the rebound force of the first spring. After the drainage tube is placed in the clamping plate 7, the fixing block 8 is closed to make the buckle embedded in the buckle groove, and the fixing block 8 can be fixed by the buckle.
[0032] The working process of the utility model is as follows: when using the drainage tube holding device, the user first presses the button block 202 to press the buckle into the slot 201, then opens the fixing block 8, puts the drainage tube into the clamping plate 7, then pulls the handle to move the rotating rod 502 to the gear 301, and then the user rotates the gear 301 as needed to adjust the distance between the two groups of clamping devices 1. At the same time, the pulley slides in the slide groove 401, so that the second moving block 4 can slide more smoothly when sliding in the first moving block 3. When the required distance is adjusted, the handle is released, and the fixing rod 501 is reset by the elastic force of the third spring. At this time, the fixing rod 501 enters the gear 301 to fix the gear 301. Then the user closes the fixing block 8, so that the buckle is embedded in the buckle groove to fix the fixing block 8. At this time, the clamping plate 7 clamps the drainage tube through the rebound force of the second spring 6. Then the user uses tape to stick on the first moving block 3 between the two groups of clamping devices 1 to fix the drainage tube holding device on the patient.
[0033] The entire operation process is simple and convenient. Compared with the existing drainage tube holding device, the utility model can flexibly adjust the fixed length of the drainage tube during the process of fixing the drainage tube through the design of the clamping device and the moving device.
