Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage auxiliary equipment, in particular to a drainage tube anti-bending device. Background Art
[0002] Most of the existing drainage devices are composed of a drainage bottle and a drainage tube. One end of the drainage tube is inserted into the drainage bottle, and the other end is inserted into the patient's body. Gravity is used for drainage. It is clinically used to guide pus, blood, etc. accumulated between human tissues or in the body cavity to the outside of the body. It has the functions of preventing postoperative infection and promoting wound healing. When in use, the drainage tube must be kept unobstructed to avoid folding and twisting of the drainage tube. The drainage tube must be properly fixed to prevent the drainage tube from encountering external force when the patient moves, causing the tube body to bend. The fit of the inner wall of the tube at the folding point will make the front and back unsmooth, resulting in poor drainage. In particular, the connection between the drainage tube and the drainage bottle is prone to tube folding, which affects the discharge of blood or pus. Therefore, a drainage tube anti-bending device is needed to avoid bending. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 4 It is given, including a left and right axial and arc-shaped wrapping layer 1, two upper and lower opposite and semicircular fixing rings 2 are respectively provided at the left and right ends of the wrapping layer 1, the two fixing rings 2 are hingedly connected, and the front ends of the two fixing rings 2 are respectively provided with fixing blocks 3, a movable groove 4 is provided at the front end of the lower fixing block 3, a slot 5 connected with the movable groove 4 is provided at the upper end of the lower fixing block 3, a clamping plate 6 is slidably connected in the movable groove 4, a rectangular clamping groove 7 is provided on the clamping plate 6, a clamping block 8 which can be inserted into the clamping groove 7 and can cooperate with the clamping plate 6 is provided at the lower end of the upper fixing block 3, and the rear end face of the clamping block 8 is an inclined surface with a low front and a high rear.
[0016] In order to facilitate the movement of the clamping plate 6 , the front end of the clamping plate 6 extends out of the movable slot 4 and is provided with a pressing plate 9 .
[0017] In order to facilitate the resetting of the clamping plate 6 , a resetting plate 10 is provided at the rear end of the clamping plate 6 , and the rear end of the resetting plate 10 is connected to the fixing block 3 via a compression spring 11 .
[0018] For ease of use, the wrapping layer 1 is made of a harder material, such as silicone or rubber, and is bendable but not easily folded.
[0019] In order to facilitate closing of the wrapping layer 1, Velcro 12 is respectively provided at the two free ends of the wrapping layer 1, and the Velcro 12 on the upper and lower sides can be bonded to each other.
[0020] In order to enhance the fixing effect, an anti-slip strip 13 is provided on the inner surface of the fixing ring 2 .
[0021] When the utility model is in use, first press the two pressure plates 9 backwards, the pressure plate 9 drives the card plate 6 to move backwards, the card plate 6 drives the card slot 7 to move backwards and compress the compression spring 11 backwards, after the card slot 7 moves backwards for a distance, the card block 8 is completely located in the card slot 7 and is out of contact with the card plate 6, at this time the card plate 6 is out of contact with the card block 8, the fixed limit of the card block 8 is released, and then the fixed limit of the upper fixed block 3 is released, at this time the upper fixed ring 2 is rotated upwards, the upper fixed ring 2 drives the card block 8 to swing upwards, and after swinging a certain angle, the fixed block 3 extends out of the slot 5;
[0022] When the upper fixing ring 2 swings upward, it also drives one end of the wrapping layer 1 to swing upward, so that the distance between the two free ends of the wrapping layer 1 becomes larger. At this time, the connection between the drainage tube and the drainage bottle is inserted into the two fixing rings 2 on the left, and then a section of the drainage tube is inserted into the wrapping layer 1, and the other section of the drainage tube is inserted into the two fixing rings 2 on the right, and then the two upper fixing rings 2 are pressed downward, and the upper fixing rings 2 drive the clamping block 8 to swing downward. After swinging a certain distance, the clamping block 8 is inserted into the slot 5, and the clamping block 8 continues to swing downward until the inclined surface contacts the clamping plate 6, and presses the clamping plate 6 to move backward and squeeze the compression spring 11 backward. After moving backward for a certain distance, the clamping block 8 is completely located under the clamping plate 6. At this time, due to the loss of squeezing of the clamping block 8 and the forward restoring force of the compression spring 11, the clamping plate 6 is driven to move forward, and cooperates with the clamping block 8 to achieve fixed limit of the clamping block 8;
[0023] When the two fixing rings 2 are close to each other, they contact with the drainage tube and clamp the drainage tube, thereby fixing the fixing ring 2 at the connection between the drainage bottle and the drainage tube to prevent sliding. Then the two Velcro strips 12 are fitted together to prevent the drainage tube in the wrapping layer 1 from being exposed. At this time, since the wrapping layer 1 is relatively hard, it will not bend, thereby preventing the drainage tube in the wrapping layer 1 from being bent.
[0024] Compared with the prior art, the beneficial effects of the utility model are: the fixed ring, fixed block, wrapping layer, etc. are provided, which can wrap the drainage tube at a distance, thereby preventing the drainage tube at the connection between the drainage bottle and the drainage tube from bending due to a special position relationship, avoiding the discharge of blood or pus to cause harm to the patient. At the same time, the fixed ring realizes positioning to prevent the wrapping layer from sliding on the drainage tube. This structure is simple, novel in conception, easy to use and highly practical.
[0025] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.
[0026] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
