[0015] 1. This device occupies little space and can be delivered to the patient in a timely manner to drain ascites in special circumstances, making it more convenient to use. In addition, the device is simple and practical in design and has a low cost.

[0016] 2. When extracting ascites from the patient's abdominal cavity, the rotating valve will automatically close through the blocking mechanism, allowing the ascites to enter the transparent shell. After extraction, the rotating valve can be opened to allow the ascites to be discharged and collected through the discharge tube. This eliminates the need for manual removal of the support tube and needle removal, reducing some of the operation steps and improving efficiency in actual use.

[0017] 3. The counting mechanism can rotate the dial each time the pumping rod pumps out ascites, and the number of pumping times can be determined by the value on the dial indicated by the pointer, which makes it easy to judge the amount of ascites pumped out.

[0018] 4. Using an electric motor as a power source, it can move the suction rod to extract ascites without manual operation, which is more labor-saving and can also ensure uniform extraction speed, avoiding patient discomfort.

[0019] 5. By fixing the collection bag to the discharge pipe, it is convenient for people to collect some of the ascites for testing. Attached Figure Description

[0038] Example 1

[0039] A device for treating refractory ascites in patients with cirrhosis, such as Figure 1-4 As shown, the device includes a support cylinder 1, a transparent shell 2, a scale plate 3, a threaded sleeve 4, a connecting tube 5, a pumping rod 6, a drainage tube 7, a fixed tube 71, a needle 8, a blocking mechanism 10, a conveying mechanism 11, and a pushing mechanism 12. The transparent shell 2 is fixed on the support cylinder 1, and the scale plate 3 is fixedly connected to the transparent shell 2. The threaded sleeve 4 is fixedly connected to the left side of the support cylinder 1, and the threaded sleeve 4 is threaded with a connecting tube 5. The pumping rod 6, which can extract ascites, is slidably installed inside the support cylinder 1. The pumping rod 6 is slidably connected to the inside of the transparent shell 2. The fixed tube 71 is connected to the left side of the connecting tube 5, and the drainage tube 7 is connected to the fixed tube 71. The needle 8 is connected to the left end of the drainage tube 7. The blocking mechanism 10, which can control the flow direction of ascites, is installed inside the fixed tube 71. The conveying mechanism 11, which facilitates the drainage of ascites, is installed on the connecting tube 5. The pushing mechanism 12, which can play an auxiliary role, is installed on the blocking mechanism 10.

[0040] like Figure 2 , Figure 5 and Figure 6As shown, the blocking mechanism 10 includes a guide block 101, a blocking block 102, a fixing rod 103, and a compression spring 104. Guide blocks 101 are fixed on both the upper and lower sides of the fixed tube 71. A blocking block 102 capable of blocking ascites is slidably provided between the guide blocks 101. A fixing rod 103 is fixedly connected to the right side of the fixed tube 71. The blocking block 102 is slidably connected to the fixing rod 103. A compression spring 104 is connected between the blocking block 102 and the fixing rod 103.

[0041] like Figure 1 , Figure 7 and Figure 8 As shown, the conveying mechanism 11 includes a connecting pipe 111, a discharge pipe 112, a rotary valve 113, a torsion spring 114, and a one-way valve 115. The connecting pipe 5 is connected to the connecting pipe 111 at the front. The discharge pipe 112 for draining ascites is connected to the connecting pipe 111. The rotary valve 113 is rotatably installed on the connecting pipe 111. Torsion springs 114 are connected to the upper and lower sides of the rotary valve 113 and the interior of the connecting pipe 111. The one-way valve 115 is fixed to the front of the discharge pipe 112.

[0042] like Figure 2 , Figure 9 and Figure 10 As shown, the pushing mechanism 12 includes a pushing rod 121 and a contact rod 122. The pushing rod 121 is fixedly connected to the right side of the blocking block 102, and the contact rod 122 is fixedly connected to the right side of the pushing rod 121. Both the contact rod 122 and the pushing rod 121 are located inside the connecting pipe 5, and the contact rod 122 is in contact with the rotary valve 113.

[0043] This device can provide drainage treatment for patients with ascites caused by liver disease. The device is placed beside the bedside, and the collection container is connected to the discharge pipe 112. The patient can then hold the needle 8 and insert it into the patient's abdominal cavity. Pulling the suction rod 6 to the right prevents external air from entering through the discharge pipe 112 due to the one-way valve 115. The discharge pipe 112 can only discharge, not enter. The suction force of the suction rod 6 will move the blocking block 102 to the right, compressing the spring 104. This causes the blocking block 102 to move the push rod 121 and contact rod 122 to the right. The contact rod 122 then... When the rotary valve 113 is rotated, the torsion spring 114 deforms, causing the rotary valve 113 to rotate and block the connecting pipe 111. The blocking block 102 moves to the right and is no longer in contact with the guide block 101, creating a gap between the guide blocks 101. The suction rod 6 then pumps the ascites from the abdominal cavity into the drainage tube 7, which then flows into the fixed tube 71 and the connecting tube 5, finally entering the transparent shell 2. By observing the value on the scale plate 3, the amount of ascites pumped out can be determined. After the transparent shell 2 is filled with ascites, the suction rod 6 can be pushed to the left, causing the ascites to push to the left, thus pushing the block. Block 102 moves to the left, causing the compression spring 104 to reset. Block 102 blocks the gap between guide blocks 101, preventing the ascites fluid in the transparent shell 2 from flowing into the fixed tube 71. The leftward movement of block 102 also moves the push rod 121 and contact rod 122 to the left, causing the contact rod 122 to no longer contact the rotary valve 113. The rotary valve 113 then rotates in the opposite direction and opens under the reset action of the torsion spring 114. The pumping rod 6 continues to move to the left, allowing the ascites fluid to flow through the connecting pipe 111 into the discharge pipe 112, and then through the one-way valve 115 into the collection container. After the ascites fluid is collected, people can... Repeat the above operation to drain the ascites from the patient's abdominal cavity. Calculate the amount of ascites based on the number of drainage cycles. Once the standard drainage volume is reached, the needle 8 can be removed, and the patient's wound can be treated. Then, the connecting tube 5 can be rotated, causing the fixing tube 71, drainage tube 7, and needle 8 to rotate. The connecting tube 5 can then be unscrewed from the threaded sleeve 4 to facilitate disinfection of the drainage tube 7. At the same time, the entire device can be cleaned and disinfected. After disinfection, the connecting tube 5 can be tightened back onto the threaded sleeve 4. This device occupies little space, is easy to carry, has low cost, and is highly practical. In hospital use, there is less likelihood of running out of devices.

[0044] Example 2

[0045] Based on Example 1, such as Figure 1 , Figure 11 and Figure 12As shown, it also includes a counting mechanism 13, which includes a support rod 131, a small gear 132, a support column 133, a large gear 134, a pointer 135, a rotating disk 136, and a scale 137. The support rod 131 is fixedly connected to the upper side of the rotary valve 113, and the small gear 132 is fixedly connected to the upper part of the support rod 131. The small gear 132 is unidirectional. The top of the connecting pipe 5 is fixedly connected to the support column 133. The large gear 134 is rotatably mounted on the upper part of the support column 133. The large gear 134 meshes with the small gear 132. The pointer 135 is fixedly mounted on the upper part of the support column 133. The rotating disk 136 is rotatably mounted on the support column 133. The rotating disk 136 is connected to the large gear 134. The scale 137 is slidably and rotatably mounted on the support column 133 to facilitate the calculation of the amount of ascites collected. The scale 137 is located below the pointer 135 and has a large weight.

[0046] During abdominal drainage, the suction rod 6 is pulled to the right to suction ascites. Simultaneously, the push mechanism 12 closes the rotary valve 113. The rotary valve 113 then rotates the support rod 131 and the small gear 132, which in turn rotates the large gear 134. The large gear 134 then rotates the rotating disk 136. Because the scale 137 is heavier and presses down on the rotating disk 136, the rotating disk 136 rotates the scale 137 through friction, rotating it one notch. The number of times ascites has been suctioned is indicated by the pointer 135 pointing to the value on the scale 137. After the transparent shell 2 is full, the ascites is discharged through the discharge pipe 112, causing the rotary valve 113 to close. Open valve 13 to cause the rotating valve 113 to drive the support rod 131 and the pinion 132 to reverse. Since the pinion 132 is unidirectional, it will not drive the large gear 134 to reverse. This completes one drainage of ascites. Finally, after the pointer 135 points to the value after the dial 137 is rotated, the drainage work can be stopped. When the device is not in use, the dial 137 can be lifted up slightly to reduce the contact area between the dial 137 and the rotating disk 136. The dial 137 can then be rotated in the opposite direction to reset to the initial position for the next use. After the reset is completed, release the dial 137, and the dial 137 will slide down and reset to stick to the rotating disk 136 under its own weight.

[0047] like Figure 1 , Figure 13 and Figure 14As shown, it also includes a transmission mechanism 14, which includes a motor 141, a spur gear 142, and a screw 143. The motor 141, which enables the extraction rod to automatically extract ascites, is installed on the top right side of the support cylinder 1. The output shaft of the motor 141 is connected to the spur gear 142. The right side of the support cylinder 1 is also equipped with a rotating spur gear 142. The two spur gears 142 are distributed vertically and mesh with each other. The screw 143 is fixedly connected to the extraction rod 6. The screw 143 is located inside the transparent shell 2 and is slidably connected to the support cylinder 1. The screw 143 is threadedly connected to the spur gear 142 on the lower side.

[0048] When draining the patient's abdominal cavity, the motor 141 can be started, causing the output shaft of the motor 141 to rotate, which in turn drives the upper spur gear 142 to rotate, which in turn drives the lower spur gear 142 to rotate. The lower spur gear 142 drives the screw 143 and the suction rod 6 to move to the right, so that the suction rod 6 can pump out the ascites. After the transparent shell 2 is filled with ascites, the motor 141 can be controlled to rotate in reverse, causing the output shaft of the motor 141 to rotate in reverse, which drives the two spur gears 142 to rotate in reverse. The lower spur gear 142 then drives the screw 143 and the suction rod 6 to move to the left, which squeezes the ascites in the transparent shell 2 into the discharge pipe 112 and collects it in the collection container. After discharge, the motor 141 can be turned off, thus completing one ascites extraction. Using the motor 141 as the power source makes it more labor-saving and reduces the trouble of manual operation.

[0049] like Figure 1 , Figure 2 , Figure 15 and Figure 16 As shown, it also includes a collection mechanism 15, which includes a threaded block 152, a threaded connector 153 and a collection bag 154. The threaded block 152 is fixedly connected to the front side of the discharge pipe 112. The threaded connector 153 is threadedly connected to the threaded block 152, and the collection bag 154 for collecting ascites is connected to the threaded connector 153.

[0050] like Figure 1 and Figure 3 As shown, it also includes a placement rack 9, and the placement rack 9 is fixed to the bottom of the support cylinder 1.

[0051] When using this device, if it is necessary to extract a portion of ascites for testing, the collection bag 154 can be tightened onto the threaded block 152 via the threaded connector 153. When the ascites inside the transparent shell 2 is squeezed into the discharge pipe 112, it will flow into the collection bag 154. After the ascites is collected, people can hold the collection bag 154, unscrew the threaded connector 153 from the threaded block 152, and then plug the threaded connector 153. The collection bag 154 can then be temporarily stored on the placement rack 9. After a suitable amount of ascites is drained from the patient's abdominal cavity, the collection bag 154 containing the ascites can be taken out of the placement rack 9, and a portion can be sent for testing to determine the cause of the disease. In this way, collecting ascites through the collection bag 154 is more convenient when testing is needed, and there is no need to prepare a separate container for storage.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
