Description

Technical Field

[0001] This utility model relates to the field of medical equipment, specifically to a hole expander. Background Technology

[0002] Drainage tubes are typically used for patients who need to drain fluids after surgery or in other situations. The drainage tube is covered with a medical transparent film. Because the drainage tube has a certain rigidity, the medical transparent film is prone to air leakage at the drainage tube. Therefore, an elastic sealing film is needed to tightly seal the drainage tube. The transparent film covering the elastic sealing film can effectively reduce the probability of air leakage at the medical transparent film of the drainage tube and improve the overall sealing performance of the device.

[0003] To prevent blockage of the drainage tube in the negative pressure closed drainage device, a flushing tube is also installed on the drainage tube. In order to seal the flushing tube, the elastic sealing diaphragm is provided with a diaphragm hole for inserting the drainage tube. In order to ensure the sealing after the tube is inserted, the diaphragm hole is slightly smaller than the diameter of the drainage tube. Before insertion, the hole needs to be enlarged slightly to facilitate the insertion of the tube. Usually, the hole is enlarged manually, which is time-consuming, labor-intensive, inefficient and inaccurate. Utility Model Content

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] This utility model provides a hole enlarging machine that can solve the problems of manual enlarging, which is time-consuming, labor-intensive, and inefficient in related technologies.

[0022] See Figure 1As shown in the illustration, a hole expander is provided in an embodiment of this utility model. The hole expander is used to expand the hole of an elastic sealing film. It includes: a driving device 1; at least two claws 2, mounted on the output end of the driving device 1. Each claw 2 has a claw tip 21 at its front end. The two claws 2 are positioned within the same radial cross-section of the film hole. The driving device 1 drives the two claws 2 to move towards or away from each other along the radial direction of the film hole. In this embodiment, by providing the claws 2, the claw tips 21 of the claws 2 can be inserted into the film hole. The driving device 1 can drive the two claws 2 to move towards or away from each other within the same radial cross-section of the film hole, thereby enlarging the film hole, facilitating the insertion of flexible tubing, saving time and effort, and improving work efficiency.

[0023] See Figure 1 As shown, in some embodiments, the drive device 1 is equipped with at least three claw heads 2, two of which are used to move in two directions respectively, and the other claw head 2 either does not move or is used to move in a third direction. In this embodiment, by providing at least three claw heads 2, the directions for expanding the hole can be increased. After the tube expansion is started, the tube can be expanded from three directions, making the enlarged hole more rounded and facilitating the insertion of the flexible hose. The direction of movement of the claw heads 2 can be arbitrarily determined as needed. For example, two claw heads 2 can move in the up-down direction, and the other claw head 2 can move to the left or right; or the three claw heads 2 can move in directions spaced 120° apart from each other.

[0024] See Figure 1 As shown, in some embodiments, a lubrication module 3 is provided on the housing 6, and the outlet of the lubrication module 3 is aligned with the claw head 2. In this embodiment, since the claw head 2 is a metal structure with a relatively dry surface, it is easy to damage the adhesive film during the tube expansion process. By introducing the lubrication module 3 at the rear end of the device, which contains lubricating liquid, the expanded hole can be lubricated at the same time, reducing damage to the adhesive film. This application can use a flexible hose connected to an alcohol bulb, which provides good lubrication and fast evaporation. The water outlet of the lubrication module 3 is aligned with the claw head 2 of the tube expander, and can be set to automatic water spraying or manual water spraying control.

[0025] See Figure 1 As shown, in some embodiments, a fixing member 4 is provided on one side of the claw head 2, and the lubrication module 3 is clamped in the fixing member 4. In this embodiment, by setting the fixing member 4, the lubrication module 3 can be clamped so that the lubrication module 3 is kept in a fixed position for easy use.

[0026] See Figure 1As shown, in some embodiments, a laser radar calibration device 5 is installed on one side of the claw head 2. The laser radar calibration device 5 is located between the two claw heads 2. In this embodiment, by setting the laser radar calibration device 5, after locating the center point of the adhesive film hole, the claw head 2 is driven to complete the tube expansion, thereby improving work efficiency.

[0027] See Figure 1 As shown, in some embodiments, a heating module 7 is installed at the front end of the claw 2. The heating module 7 is connected to the battery 8 via a wire. In this embodiment, the adhesive film is usually made of plastic or silicone. When the temperature is low, the hardness increases, making it difficult to expand the pores and easily damaging the adhesive film. Heating by the heating module 7 can reduce the hardness of the adhesive film and facilitate pore expansion.

[0028] See Figure 1 As shown, in some embodiments, the battery 8 is installed on the housing 6, and the housing 6 is provided with a switch. The switch is connected to the battery 8, and the battery 8 can be activated by the switch to power the heating module 7, which is convenient to use.

[0029] See Figure 2 As shown, in some embodiments, the claw head 2 is divided into a first segment 22 and a second segment 23. The first segment 22 is connected to the driving device 1, and the second segment 23 is rotatably hinged to the first segment 22. In this embodiment, by dividing the claw head 2 into two hinged ends, the angle of the claw head 2 can be adjusted by rotating it according to the size and direction of the enlarged hole, thereby increasing the flexibility of the enlarged hole and making it more applicable.

[0030] See Figure 2 As shown, in some embodiments, a screw 9 is installed at the connection between the first segment 22 and the second segment 23. In this embodiment, after adjusting the angle of the first segment 22 and the second segment 23 of the claw head 2, the screw 9 is used to fix it so that the two segments of the claw head 2 are kept at a fixed angle, making it more convenient to use.

[0031] During use, when the claw heads 2 are closed, they will automatically protrude outwards. Place the adhesive film on the operating table so that the film hole fits into the claw head 2. Then, turn on the control switch for the movement of the claw head 2 to move it outwards and expand the hole. The lubrication module 3, which extends from the back of the tube expander, contains alcohol. The outlet of the lubrication module 3 is directly opposite the claw head 2. When needed, alcohol is sprayed to complete the lubrication.
