Abstract

[0001] The utility model relates to the technical field of medical equipment, in particular to a drainage tube extrusion device. Background Art
[0002] After surgical operations, in order to drain the pus, blood, and fluid accumulated in the patient's chest or abdominal cavity to the outside of the body, a drainage tube is used to drain the pus, blood, and fluid accumulated in the chest or abdominal cavity. However, during use, thick liquids and tissues may block the drainage tubes, causing blockage, which hinders drainage and causes postoperative infection and affects wound healing. In clinical practice, manual squeezing of the drainage tube is usually used to squeeze out the blocked objects in the drainage tube to solve the problem of drainage tube blockage.
[0003] The existing drainage tube squeezing device usually clamps the drainage tube with two pressing rollers, and then moves the squeezing device to make the pressing rollers move along the drainage tube, so that the blockage in the drainage tube is squeezed and finally discharged. However, in actual use, because the sizes of drainage tubes used are different according to the operations performed by different users and the postoperative recovery conditions, the distance between the two pressing rollers of the existing squeezing device is fixed, so it can only be used for drainage tubes of a specific size, and cannot meet the use of drainage tubes of different sizes. It has certain limitations. In order to solve this problem, we propose a drainage tube squeezing device. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0035] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0036] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0037] When the user needs to squeeze the drainage tube, the user places the drainage tube and the proximal part of the surgical area between the two pressing rollers on the squeezing device, and then moves along the drainage tube toward the distal end of the surgical area. During the movement, the pressing rollers will squeeze the drainage tube so that the blood congestion or other impurities in the drainage tube are squeezed out from the tube opening.
[0038] In the related art, because the sizes of drainage tubes used vary depending on the surgeries and postoperative recovery conditions of different users, the distance between the two pressure rollers of the existing extrusion device is fixed, so it can only be used for drainage tubes of a specific size and cannot meet the needs of drainage tubes of different sizes, which has certain limitations.
[0039] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a drainage tube squeezing device. When it is needed, the user only needs to twist the nut 241 to loosen the rotating shaft 14, then pull open the shell 2 13 to expose the pressing roller 16, place the proximal end of the drainage tube away from the surgical area in the middle of the pressing roller 16, and then twist the knob 23 to make the moving block 211 slide on the shell 11. The moving block 211 moves in the opposite direction, driving the rod body 15 and the pressing roller 16 to move synchronously, thereby controlling the spacing between the pressing rollers 16, so that the pressing rollers 16 can be pressed. 6 can clamp the drainage tube, and then turn the shell body 13 back to its original position. The slide groove provided on the shell body 13 can accommodate the slider 22 fixedly connected to the other end of the rod body 15. The friction between the slider 22 and the slide groove is small, so that the rod body 15 can move more smoothly during the controlled movement. Then tighten the nut 241 to complete the fixation of the shell body 13. The user then holds the handle 12 to control the entire squeezing device 1 to move along the drainage tube toward the distal end of the surgical area. As the squeezing device 1 moves, the blood clots and other impurities in the drainage tube are squeezed out from the tube mouth.
[0040] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0041] Combination Figure 1-Figure 6The embodiment of the present application provides a drainage tube extrusion device, including an extrusion device 1; the extrusion device 1 includes: a handle 12 is fixedly connected to the outer wall of a shell 11, and the handle 12 is rotatably connected to a shell 2 13 through a rotating shaft 14; an adjustment device 2 is provided on the extrusion device 1, and the adjustment device 2 includes: a bidirectional screw 21 is arranged inside the shell 11, one end of the bidirectional screw 21 is fixedly connected to a connecting piece 231, the connecting piece 231 passes through the shell 11, and a knob 23 is provided on the connecting piece 231; a moving block 211 is threadedly connected to the bidirectional screw 21, and the moving block 211 passes through the shell 11 and is slidably connected to the shell 11, a rod body 15 is provided on the moving block 211, and a pressure roller 16 is rotatably connected to the rod body 15; a slider 22 is fixedly connected to the other end of the rod body 15; a screw 24 is rotatably connected to the rotating shaft 14, and a nut 241 is threadedly connected to the screw 24.
[0042] When it is needed, the user only needs to turn the nut 241 to loosen the rotating shaft 14, then pull open the shell 13 to expose the pressure roller 16, put the proximal end of the drainage tube in the middle of the pressure roller 16, and then turn the knob 23 to control the rotation of the bidirectional screw 21. The rotation of the bidirectional screw 21 causes the moving block 211 to rotate. At the same time, the moving block 211 and the shell 11 are connected to each other, so that the moving block 211 slides on the shell 11, and the moving block 211 moves in the opposite direction, driving the rod body 15 and the pressure roller 16 to move synchronously, thereby controlling the pressure roller 16. The spacing allows the pressure roller 16 to clamp the drainage tube, and then the shell body 13 is turned back to its original position. The slide groove provided on the shell body 13 can accommodate the slider 22 fixedly connected to the other end of the rod body 15. The friction between the slider 22 and the slide groove is small, so that the rod body 15 can move more smoothly during the controlled movement. Then tighten the nut 241 to complete the fixation of the shell body 13, and the user then holds the handle 12 to control the entire squeezing device 1 to move along the drainage tube toward the distal end of the surgical area. As the squeezing device 1 moves, impurities such as blood clots in the drainage tube are squeezed out from the tube mouth.
[0043] In some embodiments, the housing 13 is provided with a slide groove to cooperate with the slide block 22. The slide groove provided on the housing 13 is consistent with the size of the slide block 22, which can strengthen the positioning of the rod body 15 and reduce the friction when the slide block 22 moves, so that the rod body 15 moves more smoothly, improving the fluency of the entire device.
[0044] In some embodiments, the knob 23 is a sawtooth structure. The knob 23 is provided with a plurality of sawteeth, which facilitates the user to apply force while controlling the rotation angle of the knob 23.
[0045] In some embodiments, the knob 23 is provided with an empty slot inside, and a spring 232 is provided inside the empty slot. The spring 232 is compressed when the knob 23 is pressed, and the knob 23 can be quickly pulled out under the elastic force of the spring 232 when the knob 23 needs to be turned.
[0046] In some embodiments, the connector 231 is a T-shaped structure, and the protrusions at both ends of the top are slidably connected to the knob 23. The connector 231 is T-shaped, and the protrusions at both ends of the top are slidably connected to the knob 23, so that the connector 231 and the knob 23 can move synchronously, which is convenient for pressing the knob 23 while not conflicting with the process of the knob 23 controlling the rotation of the bidirectional screw 21.
[0047] In some embodiments, the knob 23 is provided with an insert block 233, and the housing 11 is provided with a slot 234. Pressing the knob 23 inserts the insert block 233 into the slot 234, thereby completing the plug-in connection between the knob 23 and the housing 11.
[0048] In some embodiments, the plug block 233 and the slot 234 are annular in shape, which can increase the contact range and friction between the two and improve the tightness of the plug connection.
[0049] In some embodiments, an anti-skid pad 25 is provided on the outer side wall of the handle 12. The anti-skid pad 25 provided on the handle 12 can prevent the user from accidentally not holding the handle 12 firmly and causing the device to fall off and cause risks.
