In addition, for the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.

[0047] In the present disclosure, it should be understood that terms such as "include" or "have" are intended to indicate the presence of features, numbers, steps, behaviors, components, parts, or a combination thereof disclosed in the present specification, and are not intended to exclude the possibility that one or more other features, numbers, steps, behaviors, components, parts, or a combination thereof exist or are added.

[0048] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] In the process of proposing the present disclosure, the inventors found that exudation often occurs in the puncture hole, which has a significant impact on the patient's quality of life. The dressing needs to be changed many times a day, which greatly increases the workload of medical staff. The cost of dressing changes also increases the financial burden on patients.

[0050] According to the technical solution provided in the embodiment of the present disclosure, a drainage tube is used for drainage; a supporting tube is connected around a specific position in the middle of the drainage tube and is used to support an opening and closing control device; an opening and closing control device is movably connected to the supporting tube, and the opening and closing control device guides the opening and closing device to expand when the opening and closing control device moves in a first direction toward the drainage inlet of the drainage tube, and guides the opening and closing device to close when the opening and closing control device moves in the opposite direction of the first direction; an opening and closing device, one end of the opening and closing device away from the drainage inlet of the drainage tube is connected to the opening and closing control device, and the other end of the opening and closing device close to the drainage inlet of the drainage tube is connected to the supporting tube, the opening and closing device is expanded when the two ends of the opening and closing device are close to each other, and the opening and closing device is closed when the two ends of the opening and closing device are away from each other, thereby preventing leakage from the puncture hole, improving patient comfort, reducing the labor intensity of medical staff, and saving costs.

[0051] Figure 1 FIG. 2 shows a schematic structural diagram of an anti-leakage drainage tube according to an embodiment of the present disclosure. Figure 1 As shown, the anti-leakage drainage tube 100 includes: a drainage tube 110 , a supporting tube 120 , an opening and closing control device 130 and an opening and closing device 140 .

[0052] The drainage tube 110 is used for drainage.

[0053] The supporting tube 120 is connected around a specific position in the middle of the drainage tube 110 to support the opening and closing control device 130 .

[0054] The opening and closing control device 130 is movably connected to the supporting tube 120. When the opening and closing control device 130 moves in a first direction toward the drainage inlet of the drainage tube 110, it guides the opening and closing device 140 to expand. When the opening and closing control device 130 moves in the opposite direction of the first direction, it guides the opening and closing device 140 to close.

[0055] For the opening and closing device 140, one end of the opening and closing device 140 away from the drainage inlet of the drainage tube 110 is connected to the opening and closing control device 130, and the other end of the opening and closing device 140 close to the drainage inlet of the drainage tube 110 is connected to the supporting tube 120. When the two ends of the opening and closing device 140 are close to each other, the opening and closing device 140 is expanded, and when the two ends of the opening and closing device 140 are away from each other, the opening and closing device 140 is closed.

[0056] In one embodiment of the present disclosure, the support tube 120 and the drainage tube 110 can be manufactured and formed at the same time, or they can be manufactured separately and then the support tube 120 is wrapped around the specific position in the middle of the drainage tube 110. The specific position in the middle can be any position in the middle of the drainage tube 110, such as a position at a specific distance from the drainage inlet of the drainage tube 110, so as to facilitate the use of medical staff, and facilitate the medical staff to cut the drainage tube according to different parts of the patient's drainage, thereby improving the patient's comfort. When the anti-leakage drainage tube 100 is placed in the patient's body, the opening and closing control device 130 guides the opening and closing device 140 to unfold in the patient's body and close to the puncture hole, thereby preventing liquid from seeping out of the puncture hole, improving the patient's comfort, reducing the repetitive work of medical staff, and reducing the economic burden on the patient. When the anti-leakage drainage tube 100 is taken out of the patient's body, the opening and closing control device 130 guides the opening and closing device 140 to close, and then takes it out from the puncture hole, avoiding harm to the patient and improving the patient's comfort. The insertion and removal process is convenient and quick and can be completed within one minute.

[0057] Figure 2 Shown according to Figure 1 The structural schematic diagram of the opening and closing device shown.

[0058] like Figure 2 As shown, the opening and closing device 140 includes: a first bracket 141 , a second bracket 142 and an anti-leakage membrane 143 .

[0059] With respect to the first bracket 141, the first end of the first bracket 141 is connected to Figure 1 The opening and closing control device 130 is shown.

[0060] Regarding the second bracket 142, the first end of the second bracket 142 is connected to Figure 1 In the illustrated supporting tube 120 , the second end of the second bracket 142 is connected to the first bracket 141 .

[0061] The anti-leakage membrane 143 is fixed on the first bracket 141 and the second bracket 142 .

[0062] In one embodiment of the present disclosure, the flexible deployment and closure of the opening and closing device 140 is achieved by the first bracket 141 and the second bracket 142 being movably connected, and the relative movement between the first bracket 141 and the second bracket 142. The anti-leakage membrane 143 is fixed on the first bracket 141 and the second bracket 142, and can be deployed with the relative movement between the first bracket 141 and the second bracket 142, thereby preventing the patient's liquid from leaking, and can also be closed with the relative movement between the first bracket 141 and the second bracket 142, so as to facilitate the removal from the patient's puncture hole, avoid harm to the patient, and improve the patient's comfort. It can be understood by those skilled in the art that the opening and closing device can also include other brackets besides the first bracket 141 and the second bracket 143, and the anti-leakage membrane 143 can also be fixed only on the first bracket 141, or only on the second bracket 142.

[0063] The opening and closing device includes: a first bracket, a first end of the first bracket is connected to the opening and closing control device; a second bracket, a first end of the second bracket is connected to the supporting tube, and the second end of the second bracket is connected to the first bracket; and an anti-leakage membrane is fixed on the first bracket and the second bracket, so that the opening and closing device can be easily unfolded and closed.

[0064] In one embodiment of the present disclosure, in the connection mode between the second bracket and the first bracket, the second end of the second bracket can be connected to the second end of the first bracket, and the anti-leakage membrane forms a complete double-layer structure after unfolding, and the sealing effect is better; the second end of the second bracket can also be connected to the middle part of the first bracket, thereby saving a certain amount of anti-leakage membrane material and bracket material. The two connection modes provide different connection design options, and both can achieve flexible opening and closing. It can be understood by those skilled in the art that other connection modes can also be used between the first bracket and the second bracket.

[0065] The second end of the second bracket is connected to the second end of the first bracket; or the second end of the second bracket is connected to the middle part of the first bracket, so as to achieve a flexible opening and closing method.

[0066] In one embodiment of the present disclosure, the first bracket and the second bracket can be divided into multiple groups, uniformly surrounding the opening and closing control device, so that the opening and closing device can be evenly deployed. The anti-leakage membrane completely covers the first bracket and the second bracket, ensuring that the anti-leakage membrane has a sufficiently large area after deployment, combined with the surrounding distribution and uniform deployment of the first bracket and the second bracket, thereby achieving a good sealing and anti-leakage effect.

[0067] Good sealing and anti-leakage are achieved by the first bracket and the second bracket comprising a plurality of groups surrounding the opening and closing control device; and / or the anti-leakage membrane completely covering the first bracket and the second bracket.

[0068] In one embodiment of the present disclosure, the radius of the anti-leakage membrane after it is deployed can be 2.5 cm, which improves the patient's comfort while ensuring the anti-leakage effect and is convenient for medical staff to operate. The first end of the second bracket can be 18 cm away from the drainage inlet of the drainage tube, thereby meeting the needs of most chest and abdominal puncture drainage. Medical staff can also cut it according to their needs to improve the patient's comfort and facilitate the use of medical staff. Those skilled in the art will understand that the radius of the anti-leakage membrane after it is deployed can also be other sizes, and the first end of the second bracket can also be other lengths away from the drainage inlet of the drainage tube. The support tube can be made of hard plastic material, and the opening and closing control device can also be made of hard plastic material, so as to facilitate the operation of medical staff.

[0069] The radius after unfolding through the anti-leakage membrane is 2.5 cm; and / or the first end of the second bracket is 18 cm away from the drainage inlet of the drainage tube; and / or the supporting tube is made of hard plastic; and / or the opening and closing control device is made of hard plastic, thereby improving the comfort of patients and the convenience of operation for medical staff.

[0070] In one embodiment of the present disclosure, the opening and closing control device and the bearing tube can be movably connected by a thread, so that the opening and closing control device and the bearing tube are reliably connected. The opening and closing control device can also be moved on the bearing tube by rotating the opening and closing control device, thereby guiding the opening and closing of the opening and closing device.

[0071] The opening and closing control device is movably connected to the bearing tube through threads, so that the opening and closing control device and the bearing tube are reliably connected and can flexibly move to guide the opening and closing of the opening and closing device.

[0072] In one embodiment of the present disclosure, the opening and closing control device can be sleeved on the supporting tube to achieve a reliable connection between the opening and closing control device and the supporting tube. The latch of the opening and closing control device can be embedded in the sliding groove of the supporting tube, slide along the sliding groove and be stuck in the latch groove, so that the opening and closing device is fixed in the unfolded state after being unfolded. The latch can also withdraw from the latch groove and slide along the sliding groove, thereby guiding the opening and closing device to close.

[0073] The opening and closing control device is sleeved on the supporting tube, and is connected with the sliding groove and the clamping groove on the supporting tube through the clamping hook on the opening and closing control device, so that the opening and closing control device and the supporting tube are reliably connected and can move flexibly to guide the opening and closing of the opening and closing device.

[0074] Those skilled in the art will appreciate that the opening and closing control device and the supporting tube may also be connected in other ways.

[0075] In one embodiment of the present disclosure, a scale may be provided on the side wall of the drainage tube near the drainage inlet. Medical staff can cut the drainage tube to a suitable length according to the scale as needed for easy use. Those skilled in the art will appreciate that a mark similar to a scale may also be provided on the side wall of the drainage tube near the drainage inlet to facilitate cutting by medical staff.

[0085] A through hole 411 may be provided on the side wall of the drainage tube 410 near the drainage inlet 415, and the drainage outlet of the drainage tube 410 is divided into two outlet conduits 413 and 414, and the outlet conduits are connected to the drainage bag 450. The through hole 411 and the double outlet conduits 413 and 414 prevent the drainage tube from being blocked and ensure smooth drainage. There may be multiple through holes 411, which are evenly distributed around the drainage tube, or they may be distributed sequentially or staggered along the drainage tube. The number of through holes may vary depending on the model of the drainage tube, or may be set to a fixed number, such as 5.

[0086] A scale 412 may be provided on the side wall of the drainage tube 410 near the drainage inlet 415 , and medical staff may cut the drainage tube 410 to a suitable length according to the scale 412 to meet the needs of different patients and different parts of the body.

[0087] The supporting tube 420 may be connected around a specific position in the middle of the drainage tube 410 , such as a suitable position close to the drainage inlet 415 .

[0088] The opening and closing control device 430 surrounds the bearing tube 420. The opening and closing control device 430 can be divided into a holding part 432 and an opening and closing device connecting part 431. The holding part 432 and the opening and closing device connecting part 431 can be movably connected through an annular groove and can be flexibly rotated. The bearing tube 420 has an external thread 421, and the holding part 432 has an internal thread 433, which is engaged with the external thread 421 on the bearing tube 420.

[0089] The opening and closing device 440 includes: a first bracket 441, a second bracket 442, and an anti-leakage membrane 443. The first end 441-1 of the first bracket 441 is connected to the opening and closing device connecting part 431 of the opening and closing control device 430; the second end 441-2 of the first bracket 441 is connected to the second end 442-2 of the second bracket 442; the first end 442-1 of the second bracket 442 is connected to the bearing tube 420; the anti-leakage membrane 443 is connected to the first bracket 441 and the second bracket 442, and completely covers the first bracket 441 and the second bracket 442, so as to ensure that the opening and closing device 440 can be well unfolded and closed, and the anti-leakage membrane 443 has enough area after unfolding, so as to achieve a good anti-leakage effect. There can be multiple groups of the first bracket 441 and the second bracket 442, which evenly surround the opening and closing control device 430 to achieve a good seal. The second end 442-2 of the second bracket can also be connected to the middle of the first bracket 441, and other connection methods can also be used between the first bracket and the second bracket. In addition to the first bracket and the second bracket, other brackets can also be used.

[0090] The radius of the opening and closing device 440 after unfolding can be 2.5 cm, and can also be designed to other sizes as needed.

When taking out the anti-leakage drainage tube 400, the medical staff can rotate the holding component 432 to move the holding component 432 in the opposite direction of 434, guiding the opening and closing device 440 to close, and take it out from the puncture hole.

[0092] Figure 5 A perspective view of an anti-leakage drainage tube according to another embodiment of the present disclosure is shown.

[0093] like Figure 5 As shown, the anti-leakage drainage tube 500 and Figure 4 Compared with the anti-leakage drainage tube 400 in the embodiment of the present invention, a different connection method is adopted between the bearing tube 420 and the opening and closing control device 430. The bearing tube 420 is not provided with an external thread, but is provided with a sliding groove 422 and a clamping groove 423; the holding part of the opening and closing control device 430 is not provided with an internal thread, but is provided with a clamping shoot 435, and the clamping shoot 435 is placed in the sliding groove 422. The medical staff pushes the clamping shoot 435 of the opening and closing control device 430 to move to one side of the sliding groove 422 along the direction 434 and places it in the clamping groove 423, so that the opening and closing device is unfolded and fixed. The clamping shoot 435 is withdrawn from the clamping groove 423 and slid to the other side of the sliding groove 422 along the opposite direction of 434, so that the opening and closing device is closed. The holding part and the opening and closing device connecting part in the opening and closing control device 430 can also be combined into one part, and no longer divided into two parts, so as to simplify the design and manufacturing.

[0094] Those skilled in the art will appreciate that the opening and closing control device and the supporting room, in addition to Figure 4 The threaded connection shown and Figure 5 In addition to the illustrated latch, slide slot, and latch slot connections, other connection methods may also be used.

[0095] The above description is only a preferred embodiment of the present disclosure and an explanation of the technical principles used.
