[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the scope of protection of the present application.

[0032] As Figures 1-5 shown:

[0033] An embodiment of this application provides a cardiovascular drainage device, including a drainage tube 1, with a negative pressure drainage bottle 2 detachably connected to the connecting end of the drainage tube 1. Specifically, a drainage tube 3 is detachably connected to the connecting end of the drainage tube 1, and the drainage tube 3 is detachably connected to the negative pressure drainage bottle 2.

[0034] In this embodiment, the negative pressure drainage bottle 2, the drainage tube 3, and the detachable connection of the drainage tube 3 to the drainage tube 1 and the negative pressure drainage bottle 2 are all existing technologies and will not be described in detail.

[0035] An adhesive structure 4 is fitted and fixed on the drainage tube 1 near the connection end of the drainage tube 1.

[0036] It also includes an elastic strap 6 that can be fitted and fixed on the human body, with an operating port 604 in the middle of the elastic strap 6.

[0037] The adhesive structure 4 can be glued to the elastic strap 6.

[0038] In use, first use ultrasound or X-ray to determine the optimal puncture point on the patient's back, then fix the bandage around the patient's body, with the puncture point located in the middle of the operating port 604. Next, inject local anesthetic around the puncture point to numb the area. Then, insert the drainage tube 1 through the skin into the pleural cavity from the puncture point using a guide wire. When the drainage tube 1 is inserted through the skin into the pleural effusion location, the adhesive structure 4 comes into contact with and adheres to the elastic bandage 6, thus securing the drainage tube 1 to the elastic bandage 6. Finally, connect the negative pressure drainage bottle 2 to the connection end of the drainage tube 1 through the drainage tube 3 to perform the drainage work.

[0039] The cardiovascular drainage device provided in this embodiment features an adhesive structure 4 on the drainage tube 1 and an elastic bandage 6 that can be fitted and fixed to the human body. The elastic bandage 6 has an operating port 604 in the middle. The adhesive structure 4 can be glued to the elastic bandage 6. During drainage, after the elastic bandage 6 is fixed to the patient, the drainage tube 1 is glued to the bandage to fix the drainage tube 1. This method not only solves the problem of back pain for the patient, but also prevents adhesive residue from remaining on the patient's back, thus solving the problem of adhesive residue on the patient's back that is difficult to clean.

[0040] In some embodiments of this application, the adhesive structure 4 includes an installation strip 401, both ends of which are inlaid with a pressure-sensitive adhesive layer 402 that can be pasted onto a strap, and the pressure-sensitive adhesive layer 402 is provided with release paper 403.

[0041] The middle part of the mounting strip 401 is fixed on the drainage tube 1.

[0042] In this embodiment, the mounting strip 401 is made of elastic rubber, which allows the mounting strip 401 to adhere to the elastic strap 6, thereby improving the stability of the mounting strip 401 after it is glued to the elastic strap 6.

[0043] In use, first peel the release paper 403 off the pressure-sensitive adhesive layer 402, and then insert the drainage tube 1 into the pleural cavity. After the drainage tube 1 is inserted into the pleural effusion location, the pressure-sensitive adhesive layer 402 comes into contact with the elastic bandage 6, and the installation strip 401 is glued to the elastic bandage 6, that is, the drainage tube 1 is fixed to the elastic bandage 6, thus fixing the drainage tube 1.

[0044] In some embodiments of this application, a through hole 404 is provided in the middle of the mounting strip 401, and a locking structure 5 concentric with the through hole 404 is fixed on one side of the mounting strip 401.

[0045] The drainage tube 1 passes through both the locking structure 5 and the through hole 404, and the locking structure 5 can drive the mounting strip 401 to move along the drainage tube 1 and lock it. Specifically, after the drainage tube 1 passes through the through hole 404, it is slidably connected to the through hole 404.

[0046] In this embodiment, by setting the locking structure 5, the position of the installation strip 401 on the drainage tube 1 can be adjusted, thereby adjusting the length of the drainage tube 1 inserted into the pleural cavity to suit different patients.

[0047] In some embodiments of this application, the locking structure 5 includes a cylindrical box 501. Inside the box 501, there is a rubber ring 502 that is concentric with it and is elliptical. The two ends of the long axis of the rubber ring 502 are in contact with the inner wall of the box 501 and are respectively fixed with pressure rods 503. The pressure rods 503 extend out of the box 501 and are slidably connected to the box 501.

[0048] In this embodiment, both planar ends of the rubber ring 502 are in contact with the inner wall of the housing 501, further limiting the position of the rubber ring 502.

[0049] The drainage tube 1 passes through both the housing 501 and the rubber ring 502. When the rubber ring 502 is in a free state, the two ends of the short axis of the rubber ring 502 are clamped and fixed to the drainage tube 1. Specifically, after the drainage tube 1 passes through the housing 501, it is slidably connected to the housing 501. The housing 501 is concentric with the through hole 404 and is fixedly connected to the mounting strip 401.

[0050] In use, press both levers 503 simultaneously. The two levers 503 move towards each other at the same time, squeezing the rubber ring 502 along its long axis. The rubber ring 502 deforms, its long axis shortens, and its short axis lengthens. The force clamping the drainage tube 1 between the two ends of the short axis of the rubber ring 502 decreases, and the drainage tube 1 can be gently pulled to adjust the position of the mounting strip 401 on the drainage tube 1, which facilitates adjustment.

[0051] In some embodiments of this application, the inner wall of the rubber ring 502 is provided with two symmetrically distributed arc-shaped grooves 504, and the drainage tube 1 is clamped between the two arc-shaped grooves 504 to increase the contact area between the rubber ring 502 and the drainage tube 1 and improve the clamping and fixing effect of the drainage tube 1.

[0052] In some embodiments of this application, the contact surface between the arc groove 504 and the drainage tube 1 is provided with an anti-slip protrusion structure (not shown in the figure) to increase the friction between the drainage tube 1 and the arc groove 504, thereby further improving the effect of clamping and fixing the drainage tube 1.

[0053] In some embodiments of this application, the elastic strap 6 includes an elastic band 601, with a loop fastener 602 fixed to the inner side of one end of the elastic band 601 and a hook fastener 603 fixed to the outer side of the other end of the elastic band 601.

[0054] The operating port 604 is located in the middle of the elastic band 601.

[0055] When using, wrap the elastic band 601 tightly around the patient's body and attach the hook-and-loop fastener 602 to the loop fastener 603 so that the elastic band 601 is tightly wrapped around the patient's body in a ring. Then move the ring elastic band 601 to align the operating port 604 with the puncture point, that is, to make the puncture point located in the middle of the operating port 604.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
