Detailed Embodiment

[0018] The following will describe in detail the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described by referring to the drawings below are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] First Embodiment

[0020] Please refer to Figures 1 to 2 , Figure 1 which is a structural diagram of a nasobiliary tube 101 drainage assembly according to the first embodiment of the present invention, Figure 2 and is a partial cross-sectional view of a nasobiliary tube 101 drainage assembly according to the first embodiment of the present invention.

[0021] The present invention provides a nasobiliary tube 101 drainage assembly: including a nasobiliary tube 101 and a drainage member 102. The drainage member 102 includes a drainage bag 103, a connecting tube 104, an external threaded tube 105, an internal threaded tube 106, a cleaning tube 107, a control mechanism 108, a first liquid inlet hopper 109, a second liquid inlet hopper 110, an installation groove 111, a roller 112, a first control valve 113, a second control valve 114, a protective sleeve 115, and a round tube 116. Through the foregoing solution, the problem that in the actual use process of the existing device, the telescopic tube is blocked and the device cannot be cleaned, thus affecting the normal use of the patient, is solved.

[0022] In this embodiment, the nasobiliary duct 101 is inserted into a patient for bile drainage of the patient.

[0023] Among them, the first liquid inlet hopper 109 is communicated with the nasobiliary duct 101 and is located on one side of the nasobiliary duct 101. The external threaded pipe 105 is communicated with the first liquid inlet hopper 109 and is located on one side of the first liquid inlet hopper 109. The internal threaded pipe 106 is threadedly connected to the external threaded pipe 105 and is located outside the external threaded pipe 105. The second liquid inlet hopper 110 is communicated with the internal threaded pipe 106 and is located on one side of the internal threaded pipe 106. The connecting pipe 104 is communicated with the second liquid inlet hopper 110 and is located on one side of the second liquid inlet hopper 110. The drainage bag 103 is communicated with the connecting pipe 104 and is located on one side of the connecting pipe 104. The control mechanism 108 is arranged outside the connecting pipe 104. The cleaning pipe 107 is communicated with the connecting pipe 104 and is located on one side of the connecting pipe 104. The connecting pipe 104 is connected to the nasobiliary duct 101 through the external threaded pipe 105 and the internal threaded pipe 106. The threaded connection installation not only has sealing performance but also is convenient for disassembly and replacement, so that the drainage bag 103 can be replaced without removing the nasobiliary duct 101 when replacing, reducing the number of times of inserting into the patient's body and alleviating the pain of the patient. When the connecting pipe is blocked, the control mechanism 108 closes the connection between the connecting pipe and the nasobiliary duct 101, and flushes the blockage in the connecting pipe by injecting water into the cleaning pipe 107, thereby ensuring the smoothness of the connecting pipe 104. If it is difficult to clean, the connecting pipe 104 and the nasobiliary duct 101 can be disassembled for cleaning or replacement, solving the problem that in the actual use process of the existing device, the telescopic pipe is blocked and the device cannot be cleaned, thus affecting the normal use of the patient.

[0024] Secondly, the control mechanism 108 includes a mounting groove 111 and a roller 112. The mounting groove 111 is slidably connected to the connecting pipe 104 and is located outside the connecting pipe 104. The roller 112 is slidably connected to the mounting groove 111 and is located inside the mounting groove 111. The mounting groove 111 is used to mount the roller 112 and can slide on the connecting pipe 104 to control the position to be sealed. The inside of the mounting groove 111 is inclined, so that the roller 112 squeezes the connecting pipe 104 during the sliding process, thereby controlling the flow rate of the connecting pipe 104.

[0025] Again, the drainage assembly further includes a first control valve 113 and a second control valve 114. The first control valve 113 is connected to the cleaning tube 107 and is located on one side of the cleaning tube 107. The second control valve 114 is connected to the drainage bag 103 and is located on one side of the drainage bag 103. The first control valve 113 is used to control the closing of the cleaning tube 107 to prevent bile from flowing into it when the cleaning tube 107 is not in use. The second control valve 114 opens and closes the drainage bag 103 to discharge the liquid inside the drainage bag 103, thereby extending the service life of the device.

[0026] Finally, the drainage assembly further includes a protective sleeve 115 and a round tube 116. The round tube 116 is fixedly connected to the first liquid inlet hopper 109 and is located outside the first liquid inlet hopper 109. The protective sleeve 115 is slidably connected to the round tube 116 and is located outside the round tube 116. By sliding the protective sleeve 115 into the outside of the round tube 116, the nasal bile duct 101 is enclosed inside the protective sleeve 115 to reduce contact with the outside world, thereby reducing contamination of the device.

[0027] When using a drainage assembly of a nasal bile duct 101 of the present utility model, the nasal bile duct 101 is inserted into a patient for bile drainage of the patient. The connecting tube 104 is connected to the nasal bile duct 101 through the external thread tube 105 and the internal thread tube 106. The threaded connection installation not only has sealing performance but also can be conveniently disassembled and replaced, so that the drainage bag 103 can be replaced without removing the nasal bile duct 101, reducing the number of times of inserting into the patient's body and alleviating the patient's pain. When the communication tube is blocked, the control mechanism 108 closes the connection between the communication tube and the nasal bile duct 101, and the blockage in the communication tube is flushed by injecting water into the cleaning tube 107, thereby ensuring the smoothness of the connecting tube 104. If it is difficult to clean, the connecting tube 104 and the nasal bile duct 101 can be disassembled for cleaning or replacement, solving the problem that in the actual use process of the existing device, the telescopic tube is blocked and the device cannot be cleaned, thus affecting the normal use of the patient.

[0028] Second Embodiment

[0029] Please refer to Figure 3 , Figure 3 which is a front schematic view of a drainage assembly of a nasal bile duct 101 according to a second embodiment of the present utility model. On the basis of the first embodiment, the drainage assembly of a nasal bile duct 101 of the present utility model further includes a hanging rope 201 and a scale 202.

[0030] The lanyard 201 is fixedly connected to the drainage bag 103 and is located on one side of the drainage bag 103. The scale 202 is fixedly connected to the drainage bag 103 and is located outside the drainage bag 103. The drainage bag 103 can be suspended through the lanyard 201, and the scale 202 can be used to observe the amount of liquid inside the drainage bag 103, which is convenient for recording.

[0031] The above-disclosed is only a preferred embodiment of a nasal bile duct drainage assembly of the present utility model. Of course, the scope of the rights of the present utility model cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
