[0034] The hepatobiliary drainage and flushing device 100 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0035] Reference Figure 1-Figure 6 As shown, the hepatobiliary drainage and flushing device 100 according to the embodiment of the utility model may include: a seat body 10, a waste liquid collection bottle 20, a liquid medicine storage bottle 30, a first connecting tube 40 and a second connecting tube 50.

[0036] Specifically, the seat body 10 is provided with a first mounting structure 11 and a second mounting structure 15, and the first mounting structure 11 is used to mount the drainage needle assembly 90. The waste liquid collection bottle 20 is detachably fixed to the second mounting structure 15, and the liquid medicine storage bottle 30 is mounted on the seat body 10. One end of the first connecting tube 40 is connected to the waste liquid collection bottle 20 and the other end is used to communicate with the drainage needle assembly 90, and one end of the second connecting tube 50 is connected to the liquid medicine storage bottle 30 and the other end is used to communicate with the drainage needle assembly 90.

[0037] The waste liquid collection bottle 20, the liquid medicine storage bottle 30, the first connecting rod 174 and the second connecting rod 174 are installed together through the seat body 10, and the mobile seat body 10 can move a variety of required items to the vicinity of the patient at one time, which is conducive to adapting to different positions of different patients. And through a set of hepatobiliary drainage and flushing device 100, it is possible to perform drainage, flushing and disinfection operations on the patient, without repeatedly moving the waste liquid collection bottle 20 and the liquid medicine storage bottle 30 to perform drainage, flushing and disinfection operations respectively, reducing the waiting time between different operations and improving the efficiency of drainage, flushing and disinfection operations. For example, in some embodiments, Figure 1 As shown, a running wheel 18 (such as a universal wheel) is provided at the bottom of the seat body 10, and a push handle 19 is provided on one side of the seat body 10 for medical staff to push, so that the movement is more convenient.

[0038] The drainage needle assembly 90 can be inserted into the patient's body for drainage, flushing or disinfection operations. In some embodiments, the drainage needle assembly 90 includes a drainage needle 91 and a drainage tube 92. The drainage needle 91 is used to be inserted into the patient's body, and the drainage tube 92 is used to connect the drainage needle 91 with the first connecting tube 40 or connect the drainage needle 91 with the second drainage tube 92 to output waste liquid or deliver medicine for the drainage needle 91.

[0039] The waste liquid collection bottle 20 is detachably fixed to the second mounting structure 15, which can reduce the possibility of the waste liquid collection bottle 20 tipping over on the seat 10, reduce the shaking of the waste liquid collection bottle 20, and make the installation of the waste liquid collection bottle 20 on the second mounting structure 15 more stable, which is conducive to improving the drainage reliability and drainage efficiency. It is also convenient to pour out the waste liquid in the waste liquid collection bottle 20, clean and replace the waste liquid collection bottle 20, and reduce the possibility of bacteria breeding in the waste liquid collection bottle 20.

[0040] The drainage needle assembly 90 and the waste liquid collection bottle 20 are connected through the first connecting tube 40, and the drainage needle assembly 90 and the liquid medicine storage bottle 30 are connected through the second connecting tube 50, so as to facilitate drainage, flushing or disinfection of the patient's liver and gallbladder. For example, the effusion drawn from the patient's abdomen by the drainage needle assembly 90 can be led to the waste liquid collection bottle 20 for drainage operation through the first connecting tube 40, and the liquid medicine used for flushing in the liquid medicine storage bottle 30 can be led to the drainage needle assembly 90 and then flow into the patient's abdomen for flushing operation through the second connecting tube 50, and the disinfectant used for disinfection in the liquid medicine storage bottle 30 can be led to the drainage needle assembly 90 for disinfection operation through the second connecting tube 50, which is convenient for operation.

[0041] The hepatobiliary drainage and flushing device 100 may or may not include a drainage needle assembly 90. For example, in some embodiments, the hepatobiliary drainage and flushing device 100 includes a drainage needle assembly 90, which facilitates the installation of the drainage needle assembly 90 on the first mounting structure 11 to be more stable, and improves the stability of flushing, drainage or disinfection operations. In some embodiments, the hepatobiliary drainage and flushing device 100 does not include a drainage needle assembly 90, which facilitates the replacement of different drainage needle assemblies 90 for different patients, reduces the possibility of cross infection, and improves the safety of drainage, flushing and other operations.

[0042] According to the hepatobiliary drainage and flushing device 100 of the embodiment of the utility model, the waste liquid collection bottle 20 and the medicine storage bottle 30 can be integrated into one through the seat body 10, the first connecting tube 40 and the second connecting tube 50, which is convenient for drainage, flushing and other operations on the patient, and the waste liquid collection bottle 20 can be detachably fixed through the second mounting structure 15, reducing the possibility of the waste liquid collection bottle 20 tipping over on the seat body 10, improving the installation stability of the waste liquid collection bottle 20, and improving the drainage reliability.

[0043] In some embodiments, Figure 2 As shown, the hepatobiliary drainage and flushing device 100 includes a negative pressure pump 22, which is connected to the waste liquid collection bottle 20 and is used to suck the air in the waste liquid collection bottle 20 to put the waste liquid collection bottle 20 in a negative pressure state, thereby facilitating the suction of the patient's accumulated fluid into the waste liquid collection bottle 20 through the drainage needle assembly 90, thereby improving the drainage efficiency.

[0044] In some embodiments, Figure 3 As shown, an anti-overflow ball 21 is provided on the lower side of the portion where the waste liquid collection bottle 20 is connected to the first connecting tube 40. Too much liquid accumulated in the waste liquid collection bottle 20 will squeeze the anti-overflow ball 21, causing the anti-overflow ball 21 to move upward and block the connecting port connected to the first connecting tube 40, thereby reducing the possibility of backflow of the accumulated liquid in the waste liquid collection bottle 20 and improving drainage reliability.

[0045] The second mounting structure 15 may include one or more of a protrusion, a groove, a spring, etc., and can detachably fix the waste liquid collection bottle 20. For example, in some embodiments of the present invention, such as Figure 1-Figure 3 As shown, the second mounting structure 15 includes a retaining rib 16 and a spring-pressing member 17. The retaining rib 16 is protrudingly arranged on the upper surface of the base body 10 and defines a receiving area 161 for receiving the waste liquid collecting bottle 20. The spring-pressing member 17 is movably mounted on the retaining rib 16 and is used to press the waste liquid collecting bottle 20 located in the receiving area 161.

[0046] The retaining rib 16 is protrudingly arranged on the upper surface of the seat 10 and defines a receiving area 161. The waste liquid collection bottle 20 is placed in the receiving area 161. The retaining rib 16 can limit the waste liquid collection bottle 20 in the horizontal direction, reduce the possibility of the waste liquid collection bottle 20 being accidentally touched and tipping over in the horizontal direction, and improve the drainage reliability. And the elastic member 17 applies a pressing force to the waste liquid collection bottle 20, which can reduce the shaking that may occur when the waste liquid collection bottle 20 moves with the seat 10, reduce the possibility of the first connecting tube 40 and the drainage needle assembly 90 tilting or even falling off the tube with the waste liquid collection bottle 20, improve the stability of the waste liquid collection bottle 20 placed on the seat 10, and help protect the clinical safety of patients.

[0047] The waste liquid collection bottle 20 can be detachably fixed to the storage area 161 by the movable spring-pressing member 17. The waste liquid collection bottle 20 is placed in the storage area 161 and the spring-pressing member 17 applies a pressing force to the waste liquid collection bottle 20, which is conducive to fixing the waste liquid collection bottle 20 in the storage area 161, reducing the shaking of the waste liquid collection bottle 20, and facilitating medical personnel to fix the waste liquid collection bottle 20 for drainage and other operations. The spring-pressing member 17 is moved so that the spring-pressing member 17 no longer presses the waste liquid collection bottle 20, which is convenient for medical personnel to remove the waste liquid collection bottle 20 from the storage area 161 to pour out the waste liquid, clean or replace it.

[0048] In some embodiments, Figure 1-Figure 3 As shown, the retaining rib 16 extends in a ring shape along the circumference of the accommodation area 161, and the opposite side walls of the retaining rib 16 are respectively provided with spring-pressing members 17. The retaining rib 16 can limit the waste liquid collection bottle 20 along the circumference, and the spring-pressing members 17 on the opposite side walls of the retaining rib 16 provide a pressing force on the waste liquid collection bottle 20 on the opposite sides, thereby reducing the shaking of the waste liquid collection bottle 20 and achieving a better fixing effect on the waste liquid collection bottle 20.

[0049] In some embodiments, Figure 1-Figure 3 As shown, there can be two spring-pressing parts 17, which are respectively arranged on the two opposite side walls of the retaining rib 16, so as to reduce the number of spring-pressing parts 17 while fixing the waste liquid collection bottle 20, save materials, and make it convenient for medical staff to move the spring-pressing parts 17 with one hand, thereby facilitating the disassembly and assembly of the waste liquid collection bottle 20.

[0050] In some embodiments, Figure 1-Figure 3As shown, the elastic member 17 includes a pressing plate 171 and an elastic member 172. The pressing plate 171 is installed on the retaining rib 16 so as to be movable toward and away from the accommodating area 161 in the horizontal direction. The elastic member 172 is connected between the pressing plate 171 and the retaining rib 16 and is used to apply an elastic force toward the accommodating area 161 to the pressing plate 171. The elastic member 17 is deformed to apply an elastic force toward the waste liquid collection bottle 20 to the pressing plate 171, so that the pressing plate 171 can be moved toward the accommodating area 161 to press the waste liquid collection bottle 20; the pressing plate 171 is moved in a direction away from the accommodating area 161 to separate from the waste liquid collection bottle 20, so as to facilitate the taking of the waste liquid collection bottle 20. The contact area with the waste liquid collection bottle 20 can be increased by the pressing plate 171, and the reliability of pressing the waste liquid collection bottle 20 can be improved. The movement of the pressing plate 171 is achieved by the deformation of the elastic member 172, which is conducive to simplifying the structure and is easy to implement. The elastic member 172 can be a spring or the like.

[0051] In some embodiments, Figure 1-Figure 3 As shown, the elastic member 17 includes an operating portion 173 and a connecting rod 174, and the elastic member 172 is inserted through the connecting rod 174, and the deformation of the elastic member 172 can be limited by the connecting rod 174. The operating portion 173 is located on the outside of the retaining rib 16 (i.e., the side facing away from the accommodating area 161), and the pressing plate 171 is located on the inside of the retaining rib 16 (i.e., the side close to the accommodating area 161). The connecting rod 174 is inserted through the retaining rib, and one end of the connecting rod 174 is connected to the pressing plate 171 and the other end extends out of the accommodating area 161 and is connected to the operating portion 173, so that medical staff can operate the operating portion 173 and the connecting rod 174 outside the accommodating area 161, thereby controlling the movement of the pressing plate 171. For example, the operating portion 173 and the connecting rod 174 are pulled outward to compress and deform the elastic member 172, and the pressing plate 171 moves outward to separate from the waste liquid collection bottle 20, so as to facilitate the removal of the waste liquid collection bottle 20. The operating portion 173 and the connecting rod 174 are loosened, so that the pressing plate 171 moves inward under the elastic force of the elastic member 172 to press the waste liquid collection bottle 20, which is easy to operate.

[0052] In some embodiments, Figure 1-Figure 3 As shown, the retaining rib 16 extends in a ring shape along the circumference of the accommodating area 161, and the opposite side walls of the retaining rib 16 are respectively provided with spring-pressing parts 17, which include a pressure plate 171 and an elastic part 172. The spring-pressing parts 17 can provide a clamping force to the waste liquid collection bottle 20 on the opposite sides of the retaining rib 16 through the deformation of the elastic part 172, which is easy to implement.

[0053] In some embodiments of the present invention, Figure 1-Figure 2 and Figure 4As shown, the first mounting structure 11 includes a base 12 and a cover 13, the cover 13 can be opened and closed to cover the base 12, and the cover 13 cooperates with the base 12 to define a mounting channel 14, and the mounting channel 14 is used to accommodate the drainage needle assembly 90. The cover 13 and the base 12 can radially limit the drainage needle assembly 90 accommodated in the mounting channel 14, reduce the shaking or tilting of the drainage needle assembly 90, and improve the reliability of drainage, flushing, disinfection and other operations. Through the openable and closable connection between the base 12 and the cover 13, the drainage needle assembly 90 can be detachably mounted on the mounting channel 14, which is convenient for cleaning or replacing the drainage needle assembly 90.

[0054] For example, in some embodiments, Figure 4-Figure 5 As shown, one end of the cover 13 is hinged to the base 12 and the other end is magnetically coupled to the base 12, so that the base 12 and the cover 13 can be openably connected, and the opening and closing are achieved by magnetic attraction and hinge, the connection is more reliable, and the opening and closing operation is convenient. For example, in some embodiments, Figure 5 As shown, a first magnetic member 131 is disposed at the other end of the cover body 13, and a second magnetic member 123 is disposed at the other end of the base 12. The first magnetic member 131 and the second magnetic member 123 are magnetically matched, and the opening and closing operation is convenient.

[0055] In some embodiments, Figure 1-Figure 2 and Figure 4 As shown, the base 12 includes a base 121 and a support portion 122, the base 121 is mounted on the base 10, the support portion 122 is mounted on the base 121 so as to be movable up and down, and the cover 13 is covered on the support portion 122. The mounting channel 14 is moved up and down by the up and down movement of the support portion 122, so that the drainage needle assembly 90 mounted on the mounting channel 14 can be moved up and down, which is conducive to adjusting the drainage needle assembly 90 to an appropriate height to increase the drainage rate, and is conducive to adapting to the affected areas at different heights for drainage, flushing and other operations, and has a wide applicability.

[0056] In some embodiments, the base 12 is provided with a limiting portion, which is used to axially limit the drainage needle assembly 90, thereby reducing the possibility of the drainage needle assembly 90 being accidentally touched and causing axial movement or even falling out of the tube, thereby improving the reliability of drainage, flushing and other operations.

[0057] In some embodiments, the cover 13 is provided with a limiting portion, which can axially limit the drainage needle assembly 90, and as the cover 13 is opened and closed on the base 12, the limiting of the drainage needle assembly 90 can be controlled, which is convenient for taking or placing the drainage needle assembly 90. In some embodiments, the cover 13 and the base 12 are provided with limiting portions, which have a better limiting effect on the drainage needle assembly 90, and the reliability of drainage, flushing and other operations is higher.
