Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a drainage tube connecting device. Background Art
[0002] In clinical work, for patients who have a copper tube for pleural effusion indwelling during surgery, the copper tube for pleural effusion needs to be connected to the Pan-type drainage tube after surgery, and the patient's pleural effusion needs to be drained away by using an external negative pressure device connected to the Pan-type drainage tube. In practice, since the interface of the copper tube for pleural effusion is provided with an external thread (i.e., its tube body interface is a threaded interface), and the tube body interface of the Pan-type drainage tube is a straight-tube interface, the copper tube for pleural effusion cannot be directly connected to the Pan-type drainage tube. Therefore, medical staff are currently required to use a homemade connecting tube to connect the copper tube for pleural effusion to the Pan-type drainage tube. At present, clinically, the transition connection between the copper tube for pleural effusion and the Pan-type drainage tube is usually achieved by cutting a section from the urine bag and the drainage bag and then splicing them together. The problem with this solution is that the airtightness of the device cannot be guaranteed. Therefore, how to develop a new drainage tube connection device that can achieve a close connection between the copper tube for pleural effusion and the Pan-type drainage tube to overcome the above-mentioned problems in the prior art is a direction that technicians in this field need to further study. Utility Model Content
[0003] The utility model aims to provide a drainage tube connecting device, which can realize the transition connection between the pleural effusion copper tube and the Pan-type drainage tube and ensure the airtightness of the device.

[0005] By adopting this technical solution: when making a transition connection between the pleural effusion copper tube and the Pan-type drainage tube, first insert the tube mouth of the first round tube into the interface of the Pan-type drainage tube, so that the outer wall of the tube mouth of the first round tube fits with the inner wall of the interface of the Pan-type drainage tube, and then use the internal thread on the ring sleeve and the external thread on the interface of the pleural effusion copper tube to thread and fix, that is, the transition connection between the pleural effusion copper tube and the Pan-type drainage tube is achieved. Since the pleural effusion copper tube interface, the intermediate tube and the Pan-type tube interface are an integrated structure, its sealing performance is better than the transition tube made by cutting and splicing the urine bag and the drainage bag in the prior art.

The first ring sleeve limit retaining ring is configured to realize the movement limit of the ring sleeve along the second round tube.
[0007] By adopting this technical solution: the third round tube is extended into the interface of the pleural effusion copper tube, so that the external thread on the interface of the pleural effusion copper tube is close to the second round tube, and the ring sleeve is pushed to move along the extension direction of the tube body of the second round tube until the internal thread moves to intersect with the external thread, and the ring sleeve is rotated until the internal thread and the external thread are engaged with each other, so that the ring sleeve is used to achieve a tight connection of the interface of the pleural effusion copper tube and prevent the pleural effusion copper tube from loosening.
[0008] Preferably, the pleural effusion copper tube interface also includes a first conical tube; the large mouth end of the first conical tube is conductively connected to the second circular tube, the small mouth end of the first conical tube is conductively connected to the third circular tube, and the diameter of the third circular tube is smaller than the diameter of the second circular tube.
[0009] By adopting this technical solution: the first cone tube is used to play a buffering and limiting role, so as to prevent the third round tube from extending too deeply into the interface of the pleural effusion copper tube.
[0010] Preferably, the Pan-type pipe interface also includes a special-shaped tube, which includes a plurality of truncated cone-shaped tube bodies connected head to tail in sequence and conductively connected to each other, one end of the special-shaped tube is conductively connected to the first circular tube, and the other end is provided with a first limit ring and conductively connected to the intermediate tube, each of the truncated cone-shaped tube bodies increases in size in sequence toward the intermediate tube, and the head end face of each of the truncated cone-shaped tube bodies is smaller than the tail end face of another truncated cone-shaped tube body connected to the head end face.

[0012] Preferably, a second annular limiting retaining ring is provided on the outer wall of the tube body of the intermediate tube.
[0013] By adopting this technical solution, the moving path of the bottom wall on the ring sleeve is limited between the first ring sleeve limit retaining ring and the second ring sleeve limit retaining ring.

DETAILED DESCRIPTION
[0021] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.
[0022] Example 1, please refer to Figure 1-4 :
[0023] A drainage tube connection device includes: a pleural effusion copper tube interface 100, an intermediate tube 200 and a Pan-type tube interface 300. The pleural effusion copper tube interface 100, the intermediate tube 200 and the Pan-type tube interface 300 are connected in sequence and integrally formed.
[0024] The pleural effusion copper tube interface 100 includes a second circular tube 110, a first conical tube 120 and a third circular tube 130 which are connected in sequence; the pleural effusion copper tube interface 100 also includes a ring sleeve 140. The tube mouth of the third circular tube 130 is configured to be inserted into the interface of the pleural effusion copper tube 400. (That is, the outer diameter of the tube body of the third circular tube 130 is configured to match the inner diameter of the interface of the pleural effusion copper tube in a natural state), the large mouth end of the first conical tube 120 is connected to the second circular tube 110, and the small mouth end of the first conical tube 120 is connected to the third circular tube 130. The outer diameter of the tube body of the second circular tube 110 is greater than the outer diameter of the tube body of the third circular tube 130 and the inner diameter of the interface of the pleural effusion copper tube in a natural state.
[0025] The annular sleeve 140 includes a bottom wall and an annular side wall, one end of which is connected to the edge of the bottom wall. An internal thread 141 is provided on the inner side of the annular side wall, and the internal thread 141 is configured to match the external thread on the interface of the pleural effusion copper tube. A through hole is provided at the center of the bottom wall; the second circular tube 110 passes through the bottom wall through the through hole; the aperture of the through hole is slightly larger than the outer diameter of the second circular tube 110, so that the annular sleeve 140 can reciprocate along the tube body of the second circular tube 110. The outer wall of the tube body of the second circular tube 110 includes a first annular sleeve limit retaining ring 150; the first annular sleeve limit retaining ring 150 is configured to be arranged between the bottom wall and the first cone tube 120. The first annular sleeve limit retaining ring 150 is used to limit the movement of the annular sleeve 140 along the second circular tube 110. That is, the cross section of the first annular limit stop ring 150 is larger than the through hole, so that the bottom wall cannot reach the other side of the first annular limit stop ring 150 on the second round tube 110 .
[0026] The Pan-type pipe interface 300 includes a first circular tube 310 and a special-shaped tube 320, wherein the tube mouth of the first circular tube 310 is configured to be inserted into the interface of the Pan-type drainage tube 500. The special-shaped tube 320 includes a plurality of truncated cone-shaped tube bodies which are sequentially connected head to tail and are mutually conductive, wherein the head end face of the truncated cone-shaped tube body refers to the end with a smaller cross section on the truncated cone-shaped tube body, and the tail end face of the truncated cone-shaped tube body refers to the end with a larger cross section on the truncated cone-shaped tube body; one end of the special-shaped tube 320 is conductively connected to the first circular tube 310, and the other end is provided with a first limit retaining ring 321 and is conductively connected to the intermediate tube 200, and each of the truncated cone-shaped tube bodies increases in sequence along the direction toward the intermediate tube 200, and the head end face of each of the truncated cone-shaped tube bodies is respectively smaller than the tail end face of another truncated cone-shaped tube body connected to the head end face.
[0027] A second annular stop ring 210 is provided on the outer wall of the tube body where the intermediate tube 200 and the second circular tube 110 are connected. The bottom wall is located between the first annular stop ring 150 and the second annular stop ring 210. The second annular stop ring 210 is used to limit the movement of the annular sleeve 140 along the second circular tube 110. That is, the cross section of the second annular stop ring 210 is larger than the through hole, so that the bottom wall cannot reach the intermediate tube 200 through the second annular stop ring 210.
[0028] In practice, the working process is as follows:
[0029] When transition connection is performed between the pleural effusion copper tube and the Pan-type drainage tube 500, the tube mouth of the first circular tube 310 is first inserted into the interface of the Pan-type drainage tube 500, so that the outer wall of the tube mouth of the first circular tube 310 fits with the inner wall of the interface of the Pan-type drainage tube 500, and the special-shaped tube 320 continues to be inserted into the interface of the Pan-type drainage tube 500 along with the first circular tube 310. The elastic material properties of the interface of the Pan-type drainage tube 500 are utilized to make the inner wall of the interface of the Pan-type drainage tube 500 open and fit to the edge of at least one truncated cone-shaped tube body on the special-shaped tube 320. The edge structure of the special-shaped tube 320 is utilized to increase the friction coefficient of the inner wall of the interface of the Pan-type drainage tube 500, thereby reducing the interface of the Pan-type drainage tube 500 from slipping off the Pan-type tube interface 300.
[0030] Then, the third round tube 130 is inserted into the interface of the pleural effusion copper tube 400, so that the external thread on the interface of the pleural effusion copper tube 400 is close to the second round tube 110, and the ring sleeve 140 is pushed to move along the extension direction of the tube body of the second round tube 110 until the internal thread 141 moves to intersect with the external thread, and the ring sleeve 140 is rotated until the internal thread 141 and the external thread are engaged with each other, so that the ring sleeve 140 is used to achieve a tight connection of the interface of the pleural effusion copper tube 400 and prevent the pleural effusion copper tube 400 from being loosened. Thus, the transition connection between the pleural effusion copper tube 400 and the Pan-type drainage tube 500 is achieved.
[0031] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
