Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a multifunctional chest closed channel drainage device. Background Art

[0002] Traditional closed chest drainage technology is still a routine clinical technology. Its main technical methods are: first, the patient's skin needs to be cut with a scalpel. The incision must be much larger than the drainage tube. Then, the subcutaneous layers are stretched with a vascular clamp, and the drainage tube is inserted and sewed to the skin for fixation. The other end of the drainage tube is connected to a water seal bottle. At the same time, since the drainage tube is sutured to the skin, it is difficult to adjust the drainage tube. Once the drainage tube is blocked, the skin must be stretched and placed again, causing secondary pain. In particular, now that hospitals mostly use rapid rehabilitation treatment, the tube is removed two days after the operation. Once gas and fluid accumulation occurs again after discharge, the patient needs to be re-hospitalized for intubation. The entire treatment process is likely to cause the patient multiple pains, while also increasing the cost of treatment and the burden on patients for medical treatment.

DETAILED DESCRIPTION

[0018] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 7 As shown, a multifunctional chest closed channel drainage device of this embodiment includes a chest tube 1, and a reverse umbrella structure is provided at the bottom of the outer surface of the chest tube 1; The reverse umbrella structure includes a reverse umbrella cloth 4, a first frame 41 and a second frame 42. The first frame 41 is installed on the inner end of the reverse umbrella cloth 4, the second frame 42 is movably connected to the middle part of the first frame 41, the end of the second frame 42 is movably installed on the end surface of the chest tube 1, and the bottom of the first frame 41 is connected to a driving slide 2; the driving slide 2 is slidably installed on the outer surface of the chest tube 1, and a fixing ring 21 is provided in the middle of the upper end of the driving slide 2, and the fixing ring 21 is installed on the outer surface of the chest tube 1, and the outer surface of the driving slide 2 is threadedly connected with a clamping cap 3; Among them, pushing the driving slide 2 can expand the reverse umbrella cloth 4 or retract the reverse umbrella cloth 4. When the reverse umbrella cloth 4 is in the expanded state, by rotating the fixing ring 21, the fixing ring 21 is threadedly connected to the upper end of the chest tube 1, so as to achieve the limit fixation of the back of the driving slide 2, to prevent the driving slide 2 from losing the artificial thrust and rebounding, and fix it through the fixing ring 21, so that the reverse umbrella cloth 4 is always in the umbrella open state. At this time, by rotating the clamping cap 3, the clamping cap 3 is threadedly rotated on the outer surface of the driving slide 2 until it contacts the patient's skin. At this time, the clamping cap 3 and the expanded reverse umbrella cloth 4 can clamp the patient's skin inside and outside, so as to achieve the installation and fixation of the chest tube 1.

[0019] In addition, an extension tube 13 is provided at the middle of the upper end of the chest tube 1. The extension tube 13 provides sufficient sliding space for the driving slide 2 and the fixing ring 21. When the reverse umbrella cloth 4 is in the expanded state, the extension tube 13 can be disassembled to shorten the volume of the chest tube 1 installed on the patient's skin, making it convenient for the patient to move. A puncture tube 5 is provided in the middle of the inner side of the chest tube 1 , and the puncture tube 5 passes through the extension tube 13 ; the puncture tube 5 mainly plays a role of puncturing the patient's skin.

[0020] In addition, after the chest tube 1 is installed, the puncture tube 5 needs to be disassembled and removed, and then the cover 6 and the drainage assembly are installed on the top of the chest tube 1; The cover 6 seals and covers the opening of the chest tube 1 exposed outside the body.

[0021] The drainage assembly includes a drainage bin 8, which is snap-fitted onto the top of the cover 6 so as to be fixedly installed. A one-way liquid discharge pipe 82 is provided in the middle of the right end of the drainage bin 8, a one-way exhaust pipe 83 is provided in the middle of the left end of the drainage bin 8, and a drainage tube 81 is provided in the middle of the bottom end of the drainage bin 8. The drainage tube 81 passes through the cover 6 and is installed in the middle of the inner side of the chest tube 1.

[0022] During the installation of the drainage chamber 8, the one-way liquid discharge pipe 82 faces downward, and the one-way exhaust pipe 83 faces upward. When the one-way liquid discharge pipe 82 is used, an external drainage bag is required.

[0023] In some examples, the middle of the outer surface of the chest tube 1 is provided with an external thread structure 11, and the fixing ring 21 is threadedly connected to the external thread structure 11. The inner bottom of the chest tube 1 is provided with a raised internal thread structure 12, and the bottom of the puncture tube 5 is threadedly connected to the internal thread structure 12, so that the puncture tube 5 is fixedly connected, so as to facilitate the puncture tube 5 to drive the chest tube 1 to puncture the skin.

[0024] In some examples, a sealing rubber ring 7 is provided in the upper opening of the cover 6, and the drainage tube 81 is inserted into the chest tube 1 through the sealing rubber ring 7. When the drainage tube 81 is pulled out, the sealing rubber ring 7 plays a sealing role.

[0025] In some examples, the end of the puncture tube 5 is configured as a conical head structure to facilitate puncture.

[0026] In some examples, a soft pad is attached to the clamping surface of the clamping cap 3 to improve the comfort when in contact with the skin.

[0027] In some examples, the number of the first skeleton 41 and the corresponding second skeleton 42 of the reverse umbrella cloth 4 of the present invention can be set to 4 or 6, so as to improve the stability of the reverse umbrella cloth 4 when it is unfolded.

[0028] In some examples, the drainage tube 81 is made of a silicone tube with a self-forming structure. The end of the drainage tube 81 can be bent. When inserted into the chest tube 1, the bent part can be straightened. After being inserted into the chest tube 1, it can be restored to the bent shape due to the effect of self-forming. The end of the drainage tube 81 is set to a cross-groove structure to avoid blockage.

[0029] In some examples, a partition plate 84 is provided in the middle of the inner side of the drainage chamber 8 to separate and divert the gas and liquid, so that the gas flows upward and the liquid flows downward.

[0030] The working principle of the present invention is: The present invention provides a reverse umbrella structure at the bottom of the chest tube 1. The reverse umbrella structure allows the reverse umbrella cloth 4 to be opened without requiring too much umbrella support space after the chest tube 1 enters the chest cavity. At the same time, when puncturing, the reverse umbrella cloth 4 can be folded into a straight line to facilitate puncture entry and prevent the reverse umbrella cloth 4 from getting stuck on the chest wall when the tube is removed. The specific use process is as follows: first, the puncture tube 5 is inserted into the chest tube 1 and threadedly connected and fixed. The puncture tube 5 passes through the skin, which can drive the chest tube 1 to pass through the skin. When the reverse umbrella cloth 4 passes through the skin and chest cavity, the driving slide 2 can be pushed to push the first frame 41, so that the reverse umbrella cloth 4 is opened and in an open umbrella state. Then, by rotating the fixing ring 21, the back of the driving slide 2 can be limited and locked by the fixing ring 21 to prevent the reverse umbrella cloth 4 from rebounding and retracting. After the reverse umbrella cloth 4 is opened and fixed, the clamping cap 3 is rotated until the clamping cap 3 contacts the patient's skin. At this time, the clamping cap 3 and the opened reverse umbrella cloth 4 can clamp the patient's skin inside and outside, thereby installing and fixing the chest tube 1. At this time, by rotating the puncture tube 5, the threaded connection between the puncture tube 5 and the chest tube 1 is loosened until it is completely detached, thereby making it convenient for medical staff to pull the puncture tube 5 out of the chest tube 1, disassemble the extension tube 13, and threadably install the cover 6 at the port of the chest tube 1 exposed outside the skin for sealing.

[0031] Through the above steps, the installation and fixation of the chest closed channel drainage device is completed; When using the channel drainage device, it is only necessary to insert the drainage tube 81 through the sealing rubber ring 7 in the inner cavity of the cover 6, and then pass through the chest tube 1 to insert the tube body of the drainage tube 81 into the chest cavity for exhaust or drainage; after the treatment is completed, it is only necessary to pull out the drainage tube 81 from the chest tube 1 to achieve rapid tube removal.

[0032] Compared with traditional technologies, this closed chest channel drainage device does not require additional suture fixation, is a minimally invasive treatment, reduces treatment wounds, and will not affect patients. Even if it is fixed on the skin, it will not affect the patient's discharge from the hospital. Once gas and fluid accumulation occurs, the drainage tube 81 can be installed again in the chest tube 1 for drainage, and the drainage tube 81 can also be adjusted or quickly removed. The device of the present invention has the characteristics of small diameter, one-way drainage, self-fixation, and controllable direction of the drainage tube 81. At the same time, minimally invasive instruments can be inserted through the chest tube 1 for operation, such as adjusting the tube, irrigation, suction, spraying, and biopsy, without the need for re-operation, reducing the patient's pain and economic burden, and providing convenience for subsequent rehabilitation treatment.

[0033] In addition, when the reverse umbrella cloth 4 is in a fully expanded state, it can cover the inner opening of the chest cavity to form a membrane, isolating the space around the tube, thereby effectively avoiding the occurrence of subcutaneous emphysema and perivascular exudation.

[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
