Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a stool softening device and a stool extraction device for constipated patients. Background Technology

[0002] Clinically, constipation is a common digestive system problem, mainly manifested as reduced bowel movement frequency and difficulty in defecation, such as feeling strained, taking a long time, feeling incomplete evacuation, or needing manual assistance, and the stool is often dry and hard.

[0003] Meanwhile, for bedridden patients, limited physical activity can naturally slow down intestinal peristalsis, making them prone to constipation. When bedridden patients experience constipation, a common clinical approach is to insert gloved fingers into the patient's anus to manually remove the stool. However, in practice, some family members or nurses find this procedure unsanitary, making it difficult for them to perform this manual stool removal. Furthermore, even when family members or nurses use manual assistance, the stool of constipated patients is usually hard, making it difficult for the operator to directly remove the hard stool from the anus. This hinders the expulsion of stool from constipated patients.

[0004] Therefore, improving the ease with which family members or nurses can manually assist patients with defecation, and enhancing the smoothness of their bowel movements, are urgent technical problems that need to be solved. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings of current methods for treating constipation by providing a stool softening device and a stool extraction device for constipation patients, thereby improving the convenience of manual assistance for defecation by family members or nurses and enhancing the smoothness of stool expulsion.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] A stool softening device for constipation patients includes a rod, a movable block, and a liquid tube. The rod is inserted into the anus, with the end of the rod that extends into the anus being the insertion end. One side of the rod is a first side, and the other side of the rod opposite the first side is a second side. The liquid tube is arranged along the first side, the insertion end, and the second side.

[0008] The rod body is provided with a first sliding groove, the movable block is disposed in the first sliding groove, a first chamber is formed between the movable block and the first sliding groove, the first chamber is connected to a control component, the control component is used to control the amount of gas in the first chamber, so that the movable block moves along the first sliding groove, so that the movable block extends out of the first side or retracts into the rod body;

[0009] The liquid pipe is arranged along the first side, the insertion end of the rod, and the second side, and the liquid pipe is fixed on the insertion end. The parts of the liquid pipe corresponding to the first side, the insertion end, and the second side are liquid pipe section one, liquid pipe section two, and liquid pipe section three, respectively. Each of the liquid pipe section one, liquid pipe section two, and liquid pipe section three is provided with a number of liquid outlets at intervals. The liquid pipe section one is connected to a water inlet pipe.

[0010] When the movable block retracts into the rod body, the first liquid pipe section, the second liquid pipe section, and the third liquid pipe section are connected to each other;

[0011] The width of the movable block is greater than the width of the first section of the liquid pipe. When the movable block extends out of the first side, the movable block abuts against and squeezes the first section of the liquid pipe, and can achieve the degree to isolate the liquid pipe, so that the first section of the liquid pipe is isolated from the second and third sections of the liquid pipe.

[0012] As a preferred technical solution of this application, an elastic component is connected to the end of the liquid tube section away from the liquid tube section 2, and the elastic component provides elastic force to pull the liquid tube section 1.

[0013] When the movable block retracts into the rod body, the elastic component pulls a section of the liquid tube so that the section of the liquid tube adheres to the surface of the first side portion;

[0014] When the movable block extends out of the first side, the elastic component pulls a section of the liquid tube so that the movable block abuts against and squeezes the section of the liquid tube, thereby achieving the degree to which the liquid tube is cut off.

[0015] As the preferred technical solution of this application, a limiting hole is provided on the first side, a section of the liquid tube passes through the limiting hole, and the part of the movable block extending out from the first side is located between the inserted end and the limiting hole.

[0016] As the preferred technical solution of this application, the elastic component includes a first spring and an adjusting member. The first spring is elastic, one end of the first spring is connected to a section of the liquid pipe, and the other end is connected to the adjusting member. The adjusting member is disposed on the rod body, and the position of the adjusting member is adjustable along the length direction of the rod body.

[0017] As the preferred technical solution of this application, the adjusting member is threadedly connected to the rod body.

[0018] As the preferred technical solution of this application, a first receiving groove is formed on the rod body. The first receiving groove is arranged along the first side, the extended end and the second side. The first receiving groove is adapted to the liquid tube and is used to receive the liquid tube.

[0019] As a preferred technical solution of this application, the movable block is provided with a groove so that the part of the movable block for extending out of the first side has an arc-shaped baffle structure, and the opening direction of the groove is opposite to the extension end.

[0020] As the preferred technical solution of this application, the control component includes an air pipe and an air supply device. The air pipe connects the first chamber and the air supply device. The air supply device is used to input or discharge gas into the first chamber so that the movable block moves along the first slide groove to drive the movable block to extend out of the first side or retract into the rod body.

[0021] The air supply component is an air bag or an air cylinder. A second spring is provided in the first chamber. The second spring is elastic and connects the movable block and the inner wall of the first chamber. When the second spring is in the initial state, the movable block retracts into the rod body.

[0022] As the preferred technical solution of this application, the water inlet pipe is connected to a water injector, which includes a water injection cylinder and a water injection piston. By pushing the water injection piston, the liquid in the water injection cylinder is injected into the liquid pipe through the water inlet pipe. The water injection cylinder is provided with a filling port for adding liquid into the water injection cylinder.

[0023] The present invention also provides a fecal extraction device for constipated patients, including a fecal softening device for constipated patients as described above, and a handle connected to a rod body, the handle being for the operator to hold.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. In the scheme of this application, when a constipated patient has difficulty defecating on their own, a family member or nurse can use the stool softening device to soften the hard stool in the patient's anus. Specifically, before the rod is inserted, the movable block is retracted into the rod body, and glycerin is injected into the inlet pipe so that the glycerin can flow out from the outlets on the first, second, and third sections of the liquid pipe, thereby pre-lubricating the first side, the inserted end, and the second side. Then, during the process of inserting the rod into the patient's anus, the rod body... Insert the rod into the area between the feces and the rectal wall, so that the first side contacts the feces and the second side contacts the rectal wall. At this time, the first, second and third sections of the liquid tube can still be in a conductive state. In this way, as the rod continues to be inserted, glycerin can be injected into the liquid tube midway, so that glycerin can flow out of the first, second and third sections of the liquid tube, thereby replenishing the glycerin on the surface of the rod, so as to maintain good lubrication on the surface of the rod during the continuous insertion of the rod, thereby improving the smoothness of the rod insertion.

[0026] Once the rod is inserted into the area between the feces and the rectal wall, the insertion can be stopped. At this point, the gas volume in the first chamber can be increased by controlling the control components, causing the movable block to extend out of the first side. When the movable block extends out of the first side, it can abut against and squeeze the first section of the liquid tube, thus isolating the first section of the liquid tube from the second and third sections. Then, glycerin can be injected into the liquid tube, so that the glycerin only flows out from the outlet on the first section of the liquid tube, which corresponds to the feces side. This facilitates the penetration of glycerin into the feces, thereby softening the feces. During this process, glycerin will not flow into the second and third sections of the liquid tube, thus avoiding excessive lubrication of the rectal wall by glycerin. In this case, the glycerin is dedicated to softening the feces, which can improve the feces softening effect and the effective utilization rate of glycerin.

[0027] Meanwhile, after the movable block extends out of the first side, the movable block can form a protruding structure that protrudes from the surface of the rod. During the subsequent removal of the rod from the anus, the movable block can drive the movement of the feces, causing the feces to move out of the anus, thereby facilitating the removal of the feces.

[0028] Furthermore, since the width of the movable block is greater than the width of the liquid tube section, after the movable block extends from the first side, it can abut against the liquid tube section. Thus, after the movable block extends from the first side and the liquid tube is blocked, the movable block can separate the feces into feces near the anus and feces far from the anus. When glycerin flows out from the outlet on the liquid tube section, it is more conducive to the absorption of glycerin by the feces near the anus, thereby softening the feces near the anus. This facilitates the removal of the softened feces near the anus from the patient's body during the removal of the rod. Simultaneously, the feces far from the anus absorb less glycerin, allowing the feces to remain dry and hard. This feces far from the anus is the subsequent feces to be removed. At this point, the relatively dry and hard subsequent feces to be removed are less likely to move relative to the rectal wall. This reduces the risk of pushing the subsequent feces deeper into the rectum during the subsequent insertion of the rod into the rectum. It improves the convenience of manual assistance for defecation by family members or nurses and improves the smoothness of fecal expulsion.

[0029] 2. By setting an elastic component, the elastic component can provide elastic force to pull a section of the liquid tube. In this way, when the movable block is retracted into the rod body, the elastic component pulls the section of the liquid tube so that the section of the liquid tube can be attached to the surface of the first side. Thus, during the process of the rod being inserted into the anus, the stability of the section of the liquid tube attached to the surface of the first side can be improved.

[0030] When the movable block extends out of the first side, a section of the liquid pipe is abutted by the movable block. Its elastic component can continuously pull the section of the liquid pipe, so that the movable block abuts and squeezes the section of the liquid pipe, and can isolate the liquid pipe. The elastic component can keep the section of the liquid pipe in a taut state.

[0031] 3. By forming a first receiving groove on the rod body, and arranging the first receiving groove along the first side, the insertion end and the second side, it is convenient to receive the liquid tube, so that the degree of compression of the liquid tube by the rectal wall or feces can be reduced during the process of the rod body being inserted into the body. This facilitates the flow of glycerol from the outlets on the first, second and third sections of the liquid tube during the injection of glycerol into the liquid tube, thereby improving the smoothness of the flow of glycerol from the outlets on the first, second and third sections of the liquid tube.

[0032] 4. By setting a groove, the part of the movable block that extends out of the first side is an arc-shaped baffle structure, which makes it easier for the movable block to push the feces to move during the subsequent process of the rod being pulled out of the patient's anus, and makes it easier to remove the feces.

[0033] Meanwhile, based on the groove, the part of the liquid tube corresponding to the groove is suspended, that is, the part of the liquid tube corresponding to the groove does not come into contact with other objects except for the feces. The part of the liquid tube corresponding to the groove is the suspended part of the liquid tube. When the liquid tube is thin, the suspended part of the liquid tube can play a cutting role, so that the suspended part of the liquid tube is embedded in the feces. When glycerin is injected into the liquid tube, the glycerin can flow out from the outlet on the suspended part of the liquid tube, which is more conducive to softening the feces to be removed.

[0045] Example 1: This example provides a stool softening device for constipated patients, see [link to example]. Figures 1-4As shown, it includes a rod 1, a movable block 2, and a liquid tube 3. The rod 1 is used to insert into the anus. The end of the rod 1 that inserts into the anus is the insertion end 4. One side of the rod 1 is the first side 5. The side of the rod 1 opposite to the first side 5 is the second side 6. The liquid tube 3 is arranged along the first side 5, the insertion end 4, and the second side 6.

[0046] The rod body 1 is provided with a first sliding groove 7, the movable block 2 is disposed in the first sliding groove 7, and a first chamber 8 is formed between the movable block 2 and the first sliding groove 7. The first chamber 8 is connected to a control component 9, which is used to control the amount of gas in the first chamber 8 so that the movable block 2 moves along the first sliding groove 7 so that the movable block 2 extends out of the first side 5 or retracts into the rod body 1.

[0047] The liquid pipe 3 is arranged along the first side 5, the extension end 4 of the rod 1, and the second side 6, and the liquid pipe 3 is fixed on the extension end 4. The parts of the liquid pipe 3 corresponding to the first side 5, the extension end 4, and the second side 6 are, in sequence, a first liquid pipe section 301, a second liquid pipe section 302, and a third liquid pipe section 303. Each of the first liquid pipe section 301, the second liquid pipe section 302, and the third liquid pipe section 303 is provided with a plurality of liquid outlets 10 at intervals. The first liquid pipe section 301 is connected to a water inlet pipe 11.

[0048] When the movable block 2 is retracted into the rod 1, the first liquid pipe 301, the second liquid pipe 302 and the third liquid pipe 303 are connected to each other;

[0049] The width of the movable block 2 is greater than the width of the first section of the liquid pipe 301. When the movable block 2 extends out of the first side 5, the movable block 2 abuts against and squeezes the first section of the liquid pipe 301, and can achieve the degree to isolate the liquid pipe 3, so that the first section of the liquid pipe 301 is isolated from the second section of the liquid pipe 302 and the third section of the liquid pipe 303.

[0050] In this application, when a constipated patient has difficulty defecating on their own, a family member or nurse can use this stool softening device to soften the hard stool in the patient's anus. Specifically, before the rod 1 is inserted, the movable block 2 is retracted into the rod 1, and glycerin is injected into the inlet pipe 11 so that the glycerin can flow out from the outlets 10 on the first section 301, the second section 302, and the third section 303 of the liquid pipe, thereby pre-lubricating the first side 5, the inserted end 4, and the second side 6. Then, during the process of inserting the rod 1 into the patient's anus, the rod 1 is inserted into the stool softening device. The area between the stool and the rectal wall allows the first side 5 to contact the stool and the second side 6 to contact the rectal wall. At this time, the first section 301, the second section 302, and the third section 303 of the liquid tube can still be in a conductive state. In this way, when the rod 1 is continuously inserted, glycerin can be injected into the liquid tube 3 midway, so that glycerin can flow out of the first section 301, the second section 302, and the third section 303 of the liquid tube, thereby replenishing the glycerin on the surface of the rod 1, so that the surface of the rod 1 can maintain good lubrication during the continuous insertion of the rod 1, thereby improving the smoothness of the insertion of the rod 1.

[0051] After the rod 1 is inserted into the area between the feces and the rectal wall, the insertion of the rod 1 can be stopped. At this time, the gas volume in the first chamber 8 can be increased by controlling its control component 9, so that the movable block 2 extends out of the first side 5. When the movable block 2 extends out of the first side 5, it can abut against and squeeze the first section of the liquid tube 301, so that the first section of the liquid tube 301 is isolated from the second section of the liquid tube 302 and the third section of the liquid tube 303. Then, glycerin can be injected into the liquid tube 3, so that the glycerin only flows out from the outlet 10 on the first section of the liquid tube 301. The outlet 10 on the first section of the liquid tube 301 corresponds to the feces side, so as to facilitate the penetration of glycerin into the feces and soften the feces. During this process, glycerin will not flow into the second section of the liquid tube 302 and the third section of the liquid tube 303, so as to avoid excessive lubrication of the rectal wall side by glycerin. In this case, the glycerin is dedicated to softening the feces, which can improve the effective utilization rate of glycerin while improving the feces softening effect.

[0052] Meanwhile, after the movable block 2 extends out of the first side 5, the movable block 2 can form a protruding structure protruding from the surface of the rod 1. In the subsequent process of removing the rod 1 from the anus, the movable block 2 can drive the feces to move out of the anus, thereby facilitating the removal of the feces.

[0053] Furthermore, since the width of the movable block 2 is greater than the width of the liquid pipe section 301, after the movable block 2 extends out of the first side portion 5, it can abut against the liquid pipe section 301. Therefore, after the movable block 2 extends out of the first side portion 5 and the liquid pipe 3 is blocked, the movable block 2 can separate the feces into feces near the anus and feces far from the anus. When glycerin flows out from the outlet 10 on the liquid pipe section 301, it is more conducive to the absorption of glycerin by the feces near the anus, thereby softening the feces near the anus and facilitating the removal of the rod 1. In this process, the softened stool near the anus is removed from the patient's body. At the same time, the stool further away from the anus absorbs less glycerol, allowing it to remain dry and hard. This stool further away from the anus is the stool to be removed later. At this point, the relatively dry and hard stool is less likely to move relative to the rectal wall. This reduces the risk of pushing the stool to be removed deeper into the rectum during the subsequent insertion of the rod 1 into the rectum. It can improve the convenience of manual assistance for defecation by family members or nurses and improve the smoothness of defecation.

[0054] As the preferred technical solution of this application, an elastic component 12 is connected to the end of the liquid tube section 301 that is away from the liquid tube section 302. The elastic component 12 provides elastic force to pull the liquid tube section 301.

[0055] When the movable block 2 retracts into the rod body 1, the elastic component 12 pulls the liquid tube section 301 so that the liquid tube section 301 adheres to the surface of the first side portion 5;

[0056] When the movable block 2 extends out of the first side portion 5, the elastic component 12 pulls a section of the liquid pipe 301 so that the movable block 2 abuts against and squeezes the section of the liquid pipe 301, and can achieve the degree to isolate the liquid pipe 3.

[0057] Furthermore, by providing an elastic component 12, which can provide elastic force to pull the liquid tube section 301, when the movable block 2 is retracted into the rod body 1, the elastic component 12 pulls the liquid tube section 301 so that the liquid tube section 301 can adhere to the surface of the first side portion 5. Thus, during the process of the rod body 1 being inserted into the anus, the stability of the liquid tube section 301 adhering to the surface of the first side portion 5 can be improved.

[0058] When the movable block 2 extends out of the first side 5, the section 301 of the liquid pipe is abutted by the movable block 2. Its elastic component 12 can continuously pull the section 301 of the liquid pipe, so that the movable block 2 abuts and squeezes the section 301 of the liquid pipe, and can separate the liquid pipe 3. The setting of its elastic component 12 can keep the section 301 of the liquid pipe in a taut state.

[0059] Furthermore, the width of the movable block 2 is at least twice the width of the liquid pipe section 301, and when the movable block 2 extends and abuts against the liquid pipe section 301, the liquid pipe section 301 contacts the central area on the movable block 2, thereby further ensuring that the movable block 2 can abut against the liquid pipe section 301 when it extends.

[0060] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-5 As shown, a limiting hole 13 is provided on the first side portion 5, and a section of the liquid tube 301 passes through the limiting hole 13. The part of the movable block 2 extending out of the first side portion 5 is located between the insertion end 4 and the limiting hole 13.

[0061] Furthermore, by providing a limiting hole 13, a section 301 of the liquid tube can pass through the limiting hole 13. During the process of the movable block 2 extending out of the first side portion 5, the movable block 2 abuts against the section 301 of the liquid tube, causing the section 301 of the liquid tube to bend at the limiting hole 13. The portion of the section 301 of the liquid tube below the limiting hole 13 can still adhere to the surface of the first side portion 5, while the portion of the section 301 of the liquid tube above the limiting hole 13 can be pushed out by the movable block 2. This facilitates the pushing out of the portion of the section 301 of the liquid tube corresponding to the movable block 2, while the portion of the section 301 of the liquid tube not corresponding to the movable block 2 adheres to the surface of the first side portion 5. At the same time, the orientation above the limiting hole 13 mentioned in this application refers to the orientation of the limiting hole 13 toward the insertion end 4.

[0062] As the preferred technical solution of this application, the elastic component 12 includes a first spring 14 and an adjusting member 15. The first spring 14 is elastic. One end of the first spring 14 is connected to a section of liquid pipe 301, and the other end is connected to the adjusting member 15. The adjusting member 15 is disposed on the rod body 1, and the position of the adjusting member 15 along the length direction of the rod body 1 is adjustable.

[0063] Furthermore, the position of the adjusting member 15 along the length of the rod 1 is adjustable, thereby adjusting the pulling force of the elastic component 12 when pulling a section 301 of the liquid tube, thereby improving the flexibility of the elastic component 12 in use.

[0064] As the preferred technical solution of this application, the adjusting member 15 is threadedly connected to the rod body 1.

[0065] Furthermore, the adjusting member 15 is threadedly connected to the rod body 1. When the adjusting member 15 is rotated, it can move along its own length direction, thereby changing the position of the adjusting member 15 and adjusting the pulling force of the elastic component 12 when pulling the section 301 of the liquid tube. This improves the convenience of adjusting the position of the adjusting member 15 along the length direction of the rod body 1. Specifically, the adjusting member 15 includes an adjusting member part 151 and an adjusting member part 152, which are rotatably connected. The adjusting member part 151 is threadedly connected to the rod body 1, and the adjusting member part 152 is connected to the first spring 14.

[0066] As the preferred technical solution of this application, a first receiving groove 16 is formed on the rod body 1. The first receiving groove 16 is arranged along the first side 5, the extension end 4 and the second side 6. The first receiving groove 16 is adapted to the liquid tube 3 and is used to receive the liquid tube 3.

[0067] Furthermore, by forming a first receiving groove 16 on the rod body 1, and arranging the first receiving groove 16 along the first side portion 5, the insertion end 4, and the second side portion 6, it is convenient to accommodate the liquid tube 3. This reduces the degree to which the liquid tube 3 is squeezed by the rectal wall or feces during the insertion of the rod body 1 into the body. As a result, during the injection of glycerol into the liquid tube 3, it is convenient for glycerol to flow out from the outlets 10 on the first section 301, the second section 302, and the third section 303 of the liquid tube. This improves the smoothness of the flow of glycerol from the outlets 10 on the first section 301, the second section 302, and the third section 303 of the liquid tube.

[0068] As the preferred technical solution of this application, the movable block 2 is provided with a groove 17 so that the part of the movable block 2 for extending the first side 5 is an arc-shaped baffle structure, and the opening direction of the groove 17 is away from the extension end 4.

[0069] Furthermore, by setting the groove 17, the part of the movable block 2 that extends out of the first side 5 is an arc-shaped baffle structure, which makes it easier for the movable block 2 to push the feces to move during the subsequent process of the rod 1 being pulled out of the patient's anus, and makes it easier to remove the feces.

[0070] Meanwhile, based on the groove 17, the part of the liquid tube section 301 corresponding to the groove 17 is suspended, that is, the part of the liquid tube section 301 corresponding to the groove 17 is not in contact with other objects except for contact with feces. The part of the liquid tube section 301 corresponding to the groove 17 is the suspended section 3011. When the liquid tube section 301 is in the shape of a thin tube, the suspended part of the liquid tube 3 can play a cutting role, so that the suspended part of the liquid tube 3 is embedded in the feces. When glycerin is injected into the liquid tube 3, the glycerin can flow out from the outlet 10 on the suspended part of the liquid tube 3, which is more conducive to softening the feces to be removed.

[0071] The limiting hole 13 is located below the movable block 2, so that when the movable block 2 extends out of the first side 5, the suspended section 3011 of the liquid pipe is inclined.

[0072] Example 3: Based on the technical solution of Example 2, further details are provided below. Figures 1-3 As shown, the control component 9 includes an air pipe 18 and an air supply component 19. The air pipe 18 connects the first chamber 8 and the air supply component 19. The air supply component 19 is used to input or discharge gas into the first chamber 8 so that the movable block 2 moves along the first slide groove 7 to drive the movable block 2 to extend out of the first side 5 or retract into the rod body 1.

[0073] The air supply component 19 is an air bag or an air cylinder. A second spring 20 is provided in the first chamber 8. The second spring 20 is elastic and connects the movable block 2 and the inner wall of the first chamber 8. When the second spring 20 is in the initial state, the movable block 2 is retracted into the rod 1.

[0074] Furthermore, by providing an air supply component 19 and a second spring 20, gas can be injected into or discharged from the first chamber 8, thereby facilitating the movement of the movable block 2 relative to the first sliding groove 7. This allows the movable block 2 to extend out of the first side portion 5 or retract into the rod body 1. When the air supply component 19 is an air bladder, pressing the air bladder allows the gas inside to be injected into the first chamber 8 through the air tube 18, causing the movable block 2 to extend out of the first side portion 5. When the external force on the air bladder is removed, the movable block 2 can gradually retract into the rod body 1 based on the restoration of the deformation of the second spring 20. When the air supply component 19 is an air injection cylinder, the principle of the air injection cylinder is the same as that of the commonly used syringe, so it will not be described in detail here.

[0075] As the preferred technical solution of this application, the water inlet pipe 11 is connected to a water injector 21, which includes a water injection cylinder 22 and a water injection piston 23. By pushing the water injection piston 23, the liquid in the water injection cylinder 22 is injected into the liquid pipe 3 through the water inlet pipe 11. The water injection cylinder 22 is provided with a filling port 24 so as to add liquid into the water injection cylinder 22.

[0076] Furthermore, by providing a water injector 21, the convenience of injecting glycerin into the liquid pipe 3 is improved, and the filling port 24 is equipped with a detachable cap to facilitate the replenishment of liquid into the water injector 21.

[0077] The rod 1 can be a square column structure with a width of 1-2cm and rounded edges, while the extended end 4 is rounded.

[0078] Example 4: This example provides a stool extraction device for constipated patients, including a stool softening device for constipated patients as described above, and also includes a handle 25, see [link to example]. Figure 1 As shown, the handle 25 is connected to the rod body 1, and the handle 25 is used for the operator to hold.

[0079] In this application, a handle 25 is provided to facilitate the operator's grip. When the air supply component 19 is an air bladder, the air bladder can be placed on the handle 25. This allows the operator to control the inflation and deflation of the air bladder with one hand while holding the handle 25, and the operator's other hand can control the water injector 21 to drive the piston movement. This improves the convenience of moving the movable block 2 and injecting liquid into the liquid pipe 3.
