DETAILED DESCRIPTION

[0016] The utility model will be further described below in combination with the drawings and embodiments.

[0017] Please refer to Figures 1 to 3 An adjustable depth with air bag type chest and abdominal cavity drainage tube, including the drainage main pipe 1 for guiding the abdominal cavity effusion outflow, the main function of the pipe is to guide the effusion in abdominal cavity to flow out smoothly. Drainage main pipe 1 is carefully divided into two parts: built-in part 11, this part is designed to be placed in the abdominal cavity; And external part 12, it is left outside the abdominal cavity to facilitate operation and adjustment.

[0018] On the outer side wall of built-in part 11, a series of annular leather sheaths 13 are installed at equal distances, these leather sheaths not only provide additional support, but also together with built-in part enclose air bag space 15. Correspondingly, corrugated expansion part 14 is arranged on external part 12 in the opposite position of annular leather sheath 13, this design enables the drainage tube to be adjusted in length as needed.

[0019] In order to realize the inflation and deflation of air bag space 15, several branch air pipes 16 are arranged skillfully inside drainage main pipe 1. One end of these branch air pipes penetrates built-in part 11 and is directly embedded in air bag space 15; the other end extends to the outside through external part 12, which is convenient for operation. The connection between branch air pipe 16 and the side wall of drainage main pipe 1 adopts airtight sealing design to ensure that gas does not leak. In the middle of branch air pipe 16 outside external part 12, valve 17 is assembled, which is used to accurately control the flow of gas.

[0020] In use, first need to open a small hole in the belly, and then the built-in part 11 carefully inserted into the abdominal cavity. In order to ensure the depth of the drainage tube inserted both safe and effective, the outer part 12 side wall near the built-in part 11 location engraved with clear scale 20, doctors can be based on the patient's body characteristics to determine and adjust the depth of insertion. Built-in part 11 placed properly, by suture drainage main tube 1 with the contact part of the belly fixed, thus completing the initial installation.

[0021] In order to achieve the inflation and deflation of the balloon space 15, the bronchus 16 is located at the end of the outer part 12 equipped with a perfect match with the syringe head connector 18. By syringe and connector 18 tight connection, and in the premise of opening the corresponding valve 17, you can inject gas into the balloon space 15. With the increase of gas (in the safe range), the balloon space 15 will gradually expand, push the corrugated stretch 14 elongation, thus achieving fine adjustment of the depth of the drainage tube. After adjustment, just close the valve can lock the current depth. If you need to shorten the length of the balloon space 15, no need to connect the syringe, just open the valve 17, using the annular skin 13 itself shape deformation recovery ability, the corrugated stretch 14 will automatically retract to the original state. This design makes the drainage tube can adapt to different ages, different body shape and different amount of effusion of patients needs.

[0022] In addition, the end of the outer part 12 is also provided with a threaded part 19, this design greatly facilitates the connection and replacement of the collection bag. And each annular skin 13 outer wall and its corresponding bronchus 16 side wall are marked with consistent mark number 21, this detail design makes the medical staff in the adjustment of the corresponding balloon space 15 can be more accurate, efficient.

[0023] I. The basic structure of the drainage tube

[0024] Drainage main tube:

[0025] Built-in part: for setting in the abdominal cavity.

[0026] The outer part: for setting in the abdominal cavity outside, the side wall near the built-in part is provided with a scale for preliminary judgment of the depth of insertion.

[0027] Annular skin: equidistantly installed on the outer wall of the built-in part, with shape deformation recovery ability.

[0028] Corrugated stretch: opposite the annular skin is set on the outer part, connected with the balloon space, can realize elongation and recovery.

[0029] Balloon space: located between the built-in part and the annular skin, inflated and deflated by the bronchus.

[0030] Bronchus:

[0031] Position: one end embedded in the balloon space, the other end through the external part is set outside.

[0032] Sealing connection: the connection between the bronchial outer wall and the drainage main pipe side wall is sealed.

[0033] Valve: located in the middle of the bronchial tube outside the external part, used to control the filling and discharging of gas.

[0034] Connector: located at one end of the bronchial tube outside the external part, matched with the syringe head, used for filling and discharging gas.

[0035] Threaded part: located at the end of the external part, convenient for connecting the liquid collection bag.

[0036] Marked numbers: each annular leather sheath outer wall and its corresponding bronchial side wall are provided with consistent marked numbers, which is convenient for adjusting the corresponding balloon space.

[0037] II. Usage method

[0038] Initial installation:

[0039] Punch the skin puncture site.

[0040] Insert the built-in part into the abdominal cavity along the hole, and judge the initial depth of insertion according to the scale.

[0041] Suture the contact part of the drainage main pipe with the belly with thread.

[0042] Adjust the depth:

[0043] Connect the syringe with the connector, open the corresponding valve, inject gas into the balloon space, and make the corrugated expansion part elongate, so as to adjust the depth of the built-in part in the abdominal cavity.

[0044] After adjustment, close the valve.

[0045] When the balloon space needs to be shortened, open the valve, and due to the deformation recovery ability of the annular leather sheath, the corrugated expansion part will automatically recover.

[0046] Connect the liquid collection bag: connect the liquid collection bag to the end of the external part through the threaded part.
