Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a medical enema device and its method of use. Background Technology
[0002] Enemas are a common clinical medical procedure, widely used in bowel cleansing, drug administration, and preoperative preparation. For example, before abdominal surgery in general surgery, an enema is usually needed to clear feces from the intestinal lumen, providing a clear field of vision and operating space for the operation. Patients with intestinal obstruction or stomas also require an enema before undergoing colonoscopy. During the procedure, medical staff inject the prepared enema solution or medication into the patient's colon and rectum, stimulating intestinal peristalsis to promote defecation and gas expulsion, thereby achieving the purpose of cleansing the intestines, diagnosing diseases, or treating diseases. Traditional enema devices mostly use a single-tube structure, with flow rate controlled by a flow rate regulating valve. While this can meet routine flushing needs, it has significant shortcomings when dealing with hard, sticky, or large pieces of feces: the limited flow rate adjustment range of a single tube makes it difficult to generate sufficient flushing force, easily leading to incomplete flushing, prolonged operation time, and even patient discomfort. In addition, the single function and inability to flexibly adjust the flushing mode according to clinical conditions also limit its application effectiveness. Summary of the Invention
[0003] To address the shortcomings of the existing technology, the present invention provides a medical enema device and its usage method to solve the problems of insufficient flushing power, poor adjustment flexibility, and limited functionality of existing enema devices.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A medical enema device includes: an enema tube comprising: an outer tube with its inlet end connected to a liquid storage device; an inner tube coaxially disposed inside the outer tube; a sliding tube, the upper end of which communicates with the cavity of the outer tube and forms a sliding seal with the inner wall of the outer tube via a connecting ring, the sliding tube portion being placed within a first channel of the inner tube; a tube head connected to one end of the outer tube, the inner tube having a flushing chamber and a reflux chamber isolated from each other, the reflux chamber being connected to a collection device, and the outer wall of the tube head having a flushing hole communicating with the flushing chamber and a reflux hole communicating with the reflux chamber; and a first flushing tube, one end of which is connected to the sliding tube. The second channel of the tube is connected, and the other end is connected to the flushing chamber; the second flushing tube is coaxially disposed in the first channel, and its lower end is connected to the flushing chamber; wherein, the medical enema device further includes: a sealing component disposed at the upper end of the second flushing tube, used to block or open the inlet of the second flushing tube; an opening and closing component disposed at the bottom of the sliding tube, and its position corresponds to the position of the sealing component; a driving component, drivenly connected to the sliding tube, used to drive the sliding tube to move axially, so that the opening and closing component and the sealing component interact, thereby controlling the opening and closing between the second channel of the sliding tube and the second flushing tube.
[0005] This invention achieves switching between single-path and dual-path flushing modes by setting up a first flushing pipe and a second flushing pipe, along with an adjustable opening and closing structure. Under normal circumstances, only the first flushing pipe performs gentle flushing; when encountering dry, hard, sticky, or large pieces of feces, the second flushing pipe can be activated to form a dual-path confluence, significantly increasing the flow rate and flushing force, thereby effectively softening and dispersing the feces, improving cleaning efficiency, and reducing the risk of clogging.
[0006] Optionally, the sealing assembly includes: a sealing element movably disposed at the inlet of the second flushing pipe for sealing the inlet; and a limiting block disposed on the inner wall of the second flushing pipe. The opening and closing assembly includes: a plugging head movably disposed on the second outlet at the bottom of the slide pipe for sealing or opening the second outlet; a sliding element slidably connected to the slide pipe, with its upper end connected to the plugging head and its lower end extending downward and engaging with the limiting block; and an actuator connected to the bottom end of the slide pipe, positioned vertically corresponding to the sealing element. When the driving element drives the slide pipe downward, the actuator can press down on the sealing element to release its sealing of the inlet of the second flushing pipe, and the sliding element, under the action of the limiting block, causes the plugging head to disengage from the second outlet, thereby connecting the second channel with the second flushing pipe.
[0007] Optionally, the second flushing pipe includes, from top to bottom, a coaxially connected inlet section, a flared section, and a straight section, wherein the inner diameter of the flared section is larger than the inner diameter of the inlet section; the sealing assembly further includes: a sleeve, which is mounted on the upper part of the straight section via a bracket; the sealing element includes a sealing seat and a connecting rod, wherein the lower end of the sealing seat is slidably connected to the sleeve via the connecting rod, and a first elastic element is connected between the bottom of the connecting rod and the inner bottom wall of the sleeve; the upper and lower ends of the sealing seat are respectively tapered, and under the elastic force of the first elastic element, they are placed inside the inlet section to form a seal; when the actuator presses down on the sealing seat, the sealing seat moves down to the flared section to release the seal. By incorporating a flared section and inlet and straight sections at both ends within the second flushing tube, and equipping it with a sealing assembly consisting of a sealing seat, a limiting block, and a first elastic element, the second flushing tube can be adjusted to different states during use. These states include different opening degrees, closed states, or flowing states. This allows for adjustment of the fluid volume and flow rate according to the patient's specific condition, making it flexible, convenient, and widely applicable. Furthermore, the opening and closing of the second flushing tube allows for multiple, intensive flushing sessions. This avoids excessive fluid input at once and, by intermittently increasing the flow rate, generates a stronger flushing force.
[0008] Optionally, the medical enema device further includes: an air bladder, fitted over the outer tube; a sealed cavity is formed between the connecting ring and the top of the inner tube; a third channel is provided on the wall of the inner tube, connecting the cavity to the interior of the air bladder. When the sliding tube moves downward under the drive of the driving component, the connecting ring moves with the sliding tube, allowing air in the cavity to be introduced into the air bladder, causing the air bladder to inflate and effectively preventing liquid leakage during use, achieving a leak-proof effect; after use, the sliding tube returns to its initial position under the action of the driving component, and the air bladder deflates simultaneously, restoring its original state. The entire process requires no complicated operation and is simple and efficient.
[0009] Optionally, the airbag is equipped with a pressure sensor, which is electrically connected to a control element. The control element receives the pressure data sensed by the pressure sensor and displays it through a display module.
[0010] Optionally, a baffle is movably installed on the third channel. One end of the baffle is slidably connected to a mounting groove on the inner tube via a second elastic element, and the other end extends into the first channel. The end of the baffle inside the inner tube has a rounded head, and a flow hole is provided on the baffle. The flow hole can coincide with or be offset from the third channel by the extension and retraction of the baffle. Multiple flushing holes at the pipe head can disperse the liquid flow, further enhancing the flushing effect. A collection trough facilitates the recovery of contaminants.
[0011] Optionally, the medical enema device further includes: a filter assembly disposed above the slide tube; the filter assembly includes: a partition connected to the drive component, dividing the cavity into an upper heating chamber and a lower filtering chamber, the partition having a through hole; a first filter screen located within the filtering chamber and connected to the upper end of the slide tube; and a second filter screen, cylindrical in shape, fixed within the cavity by a support rod, the second filter screen slidingly engaging with the through hole of the partition, and having a sealing head at the end of the second filter screen for sealing the through hole; wherein, when the drive component moves the partition downward, the sealing head separates from the through hole, allowing the heating chamber and the filtering chamber to communicate through the internal space of the second filter screen. The partition divides the cavity into a heating chamber and a filtering chamber, allowing the heating chamber to heat the input liquid to a suitable temperature, preventing discomfort from affecting patient comfort and treatment effectiveness. After the liquid is heated, the slide tube moves the partition, simultaneously allowing the heated liquid to flow out. The outflowing liquid undergoes dual filtration through the first and second filter screens, significantly improving the filtration effect.
[0012] Optionally, the pipe head has a conical structure with a circular arc protrusion at its small end. The outer wall of the pipe head is provided with multiple sets of flushing holes at intervals, each set of flushing holes consisting of multiple flushing holes. There are multiple return holes, which are staggered with the flushing holes. A collection groove is provided between the return holes and the circular arc protrusion.
[0013] Optionally, the first flushing tube is a telescopic structure that can move synchronously with the slide tube.
[0014] Optionally, the sliding member is a sliding sleeve or a sliding rod, the upper end of the sliding member is connected to the sealing head, the lower end extends to the bottom of the sliding tube, and the actuator is located inside the sliding member.
[0015] Optionally, the upper surface of the limiting block is provided with a slot that is adapted to the sliding member.
[0016] Optionally, the liquid storage device includes a liquid storage tank, which is connected to the cavity via a conduit. A pump body is mounted on the conduit, and a sensor is mounted on the limiting block. Both the sensor and the pump body are electrically connected to a control element, which receives communication data from the sensor and regulates the output pressure of the pump body. Alternatively, the driving component is an electric telescopic rod, and the liquid storage device includes a liquid storage tank, which is connected to the cavity via a conduit. A pump body is mounted on the conduit, and both the pump body and the electric telescopic rod are electrically connected to a control element, which regulates the extension and retraction of the electric telescopic rod and the output pressure of the pump body.
[0017] Optionally, the driving component is a sliding rod, and the outer tube or the sliding rod is provided with a locking element for locking and fixing the sliding rod; within the cavity, a third elastic element is sleeved on the sliding tube. The third elastic element can cause the first filter screen to vibrate, preventing clogging and ensuring smooth liquid flow.
[0018] Optionally, the elastic element can be a spring.
[0019] Optionally, the outer wall of the drive component is provided with scales or markings. The markings or scales on the drive component can accurately display the movement depth of the slide tube, facilitating precise adjustment of the slide tube position and further improving the convenience and accuracy of operation.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a first flushing tube and a second flushing tube, and in conjunction with an adjustable opening and closing structure, enables switching between single-channel and dual-channel flushing modes. During use, doctors can flexibly adjust the flow rate according to the difficulty of flushing, meeting different flushing intensities. That is: under normal circumstances, only the first flushing tube is used for gentle flushing; when encountering dry, hard, sticky, or large pieces of feces, the second flushing tube can be activated to form a dual-channel confluence, significantly increasing the flow rate and flushing force. The increased liquid volume can more thoroughly soften dry, hard feces, making them easier to flush away. The enhanced flushing force can break down large pieces of feces into smaller particles, making them easier to expel. At the same time, the increased flow rate can also prevent adhering substances or feces from accumulating near the flushing holes, ensuring smooth liquid flow and reducing the risk of blockage.
[0021] 2. This invention features a flared section and inlet and straight sections at both ends within the second flushing tube, along with a sealing assembly consisting of a sealing seat, a limiting block, and a first elastic element. During use, the second flushing tube can be adjusted to different states—such as different opening degrees, closed states, or flowing states—by controlling the downward movement of the opening and closing assembly. This allows for adjustment of the fluid volume and flow rate according to the patient's specific condition, making it flexible, convenient, and widely applicable. The opening and closing of the second flushing tube allows for multiple, intensive flushing sessions, preventing excessive fluid input at once and generating stronger flushing force through intermittently increasing the flow rate. Furthermore, multiple flushing holes at the tube head disperse the fluid flow, further enhancing the flushing effect.
[0022] 3. By driving the slide tube to different depths, the system not only controls the opening and closing of the second flushing tube by coordinating the opening and closing components with the sealing components, but also simultaneously adjusts the inflation and deflation of the airbag and / or the heating and filtration functions of the liquid. The entire design features high interconnectivity, simple operation, and diverse functions, significantly improving the effectiveness of the device. Specifically, when the slide tube moves downwards under the drive of the drive, the connecting ring moves with the slide tube, introducing air from the cavity into the airbag, causing the airbag to inflate and effectively preventing liquid leakage during use. After use, the slide tube returns to its initial position under the action of the drive, and the airbag deflates synchronously, restoring its original state. The entire process requires no complex operation and is simple and efficient. A partition divides the cavity into a heating chamber and a filtration chamber. The heating chamber heats the input liquid to a suitable temperature, preventing discomfort to the patient and affecting the treatment effect. After the liquid is heated, the slide tube moves the partition, simultaneously allowing the heated liquid to flow out. The outflowing liquid undergoes double filtration through the first and second filters, significantly improving the filtration effect. Furthermore, the third elastic element vibrates the first filter screen, preventing clogging and ensuring smooth liquid flow. The drive mechanism features markings or scales that precisely display the sliding depth of the slide tube, facilitating accurate adjustment of its position and further enhancing operational convenience and accuracy.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1
[0035] like Figure 1 , Figure 2 , Figures 5-8 As shown in the figure, an embodiment of the present invention provides a medical enema device, including an enema tube 1, a liquid storage device 2, a collection device 3, a sealing component 4, an opening and closing component 5, and a driving component 6.
[0036] The enema tube 1 includes an outer tube 11, an inner tube 12, a slide tube 13, a tube head 14, a first flushing tube 15, and a second flushing tube 16. A liquid storage device 2 and a collection device 3 are connected and mounted on the enema tube 1. A sealing assembly 4 is located at the upper end of the second flushing tube 16 and is used to block or open the inlet of the second flushing tube 16. An opening and closing assembly 5 is located at the bottom of the slide tube 13, and its position corresponds to that of the sealing assembly 4. A driving member 6 is drivenly connected to the slide tube 13 and is used to drive the slide tube 13 to move axially, causing the opening and closing assembly 5 and the sealing assembly 4 to interact, thereby controlling the connection and disconnection between the second channel of the slide tube 13 and the second flushing tube 16.
[0037] Specifically, The inlet end of the outer tube 11 is connected to the output end of the liquid storage device 2. The inner tube 12 and the slide tube 13 are both located inside the outer tube 11. The inner tube 12 is located at the lower part of the outer tube 11, and the end of the outer tube 11 is formed with a tube head 14.
[0038] The slide tube 13 is slidably disposed above the inner tube 12, and a portion of the slide tube 13 is placed inside the inner tube 12. That is, the upper end of the inner tube 12 has an open structure and a first channel 121 inside. The upper end of the slide tube 13 is also open, and the cavity 111 of the outer tube 11 is connected to the second channel 131 of the slide tube 13 through this opening. That is, the outer tube 11 has a cavity 111 inside, and the slide tube 13 has a second channel 131 inside, and the cavity 111 and the second channel 131 are connected. A connecting ring 132 is formed at the upper end of the slide tube 13, and the connecting ring 132 is slidably and sealingly connected to the inner wall of the outer tube 11.
[0039] The tube head 14 is formed at the lower end of the outer tube 11. It has a flushing chamber 141 and a return chamber 142 inside. The outer wall of the tube head 14 is provided with a flushing hole 143 and a return hole 144. The flushing hole 143 is connected to the flushing chamber 141, and the return hole 144 is connected to the return chamber 142.
[0040] The bottom of the slide tube 13 is closed, and it is connected to the flushing chamber 141 through the first flushing tube 15 and the second flushing tube 16. A sealing component 4 is provided at the upper end of the second flushing tube 16, and an opening / closing component 5, which works in conjunction with the sealing component 4, is provided at the bottom of the slide tube 13 corresponding to the position of the sealing component 4. A driving component 6 is connected to the slide tube 13, allowing the slide tube 13 to move a preset distance under the drive of the driving component 6. The opening / closing component 5, in conjunction with the sealing component 4, controls the connection between the slide tube 13 and the second flushing tube 16. Specifically, the bottom of the slide tube 13 has a first outlet 133. One end of the first flushing tube 15 is connected to the first outlet 133, and the other end passes through the tube head 14 and connects to the flushing chamber 141. The first flushing tube 15 can move with the slide tube 13. The second flushing tube 16 is located within the first channel 121, and its lower end passes through the tube head 14 and connects to the flushing chamber 141.
[0041] Optionally, the first flushing pipe 15 is a telescopic structure that can move synchronously with the slide pipe. For example, the first flushing pipe is a flexible hose or a telescopic pipe, which can move upward or downward under the action of the slide pipe 13.
[0042] Optionally, the lower and / or upper parts of the first flushing pipe 15 are curved. The curved structure can reduce the speed of the first flushing pipe 15.
[0043] Optionally, the outlet ends of the first flushing pipe 15 and the second flushing pipe 16 are arranged to gradually expand.
[0044] Furthermore, the sealing assembly 4 includes a seal 41 and a limiting block 42. The seal 41 is disposed at the inlet of the second flushing pipe 16 to block the inlet end of the second flushing pipe 16. The limiting block 42 is fixed to the inner wall of the second flushing pipe 16.
[0045] The opening and closing assembly 5 includes a sealing head 51, a sliding member 52, and an actuator 53. A second outlet 134 is provided at the bottom of the slide tube 13. The sealing head 51 is movably mounted on the second outlet 134 via the sliding member 52, controlling the opening and closing of the second outlet 134. Specifically, the sealing head 51 seals the second outlet 134 when it is in contact with it, and opens when it is away from it. The sliding member 52 is located outside the second outlet 134 and corresponds to the position of the limiting block 42. The sliding member 52 slides with the slide tube 13, with one end connected to the bottom of the sealing head 51 and the other end extending below the slide tube 13. The actuator 53 is connected to the bottom of the slide tube 13 and corresponds to the position of the sealing member 41.
[0046] Optionally, there can be multiple second outlets 134, which are arranged in a ring, with the actuator 53 located below the inner side of the multiple second outlets 134.
[0047] In use, the actuator 53 and the sliding member 52 move synchronously with the movement of the slide tube 13. When the slide tube 13 moves downward, the actuator 53 can contact the seal 41 and release the seal 41 from blocking the second flushing pipe 16. That is, in the initial state, the seal 41 blocks the second flushing pipe 16. When the seal 41 moves downward under force, the blockage is released. At the same time, since the sliding member 52 also moves synchronously, when the sliding member 52 moves downward and contacts the limiting block 42, the sliding member 52 will push the sealing head 51 upward under the action of the limiting block 42 to disengage from the second outlet 134, thereby connecting the second channel 131 with the second flushing pipe 16.
[0048] In one embodiment, the sliding member 52 is a sliding sleeve, with its upper end connected to the sealing head 51 and its lower end extending below the sliding tube 13. Correspondingly, the limiting block 42 can also adopt an annular structure, with the second outlet 134 and the actuator 53 both located inside the sliding sleeve.
[0049] In another embodiment, the sliding member 52 comprises at least two sliding rods, the upper end of which is connected to the sealing head 51, and the lower end of which extends below the sliding tube 13. Correspondingly, the number of limiting blocks 42 is adapted to the number of sliding members 52, and the second outlet 134 and the actuator 53 are both located inside the two sliding rods.
[0050] Optionally, the upper surface of the limiting block 42 is provided with a slot that matches the slider 52, so that the slider 52 can be better restricted in the slot, which helps to improve the stability of pushing.
[0051] In one implementation scenario, the liquid storage device 2 includes a liquid storage tank. The output end of the liquid storage tank is connected to the cavity 111 via a conduit. A pump is installed on the conduit. In use, by activating the pump, the pump draws liquid from inside the liquid storage tank into the cavity 111. In another implementation scenario, the liquid storage device 2 includes a rubber liquid storage bladder. The output end of the rubber liquid storage bladder is connected to the cavity 111 via a conduit. In use, pressing the rubber liquid storage bladder allows liquid inside to be introduced into the cavity 111 through the conduit. During actual use, the liquid pressure entering the cavity 111 can be controlled by the pump or by pressing the rubber liquid storage bladder.
[0052] In one implementation scenario, the collection device 3 includes a collection box. The input end of the collection box is connected to the return chamber 142 via a conduit. A pump is installed on the conduit. In use, by activating the pump, the pump draws the waste liquid inside the return chamber 142 into the collection box. In another implementation scenario, the collection device 3 includes a rubber bladder. The input end of the rubber bladder is connected to the return chamber 142 via a conduit. In use, pressing the rubber bladder allows the liquid in the return chamber 142 to enter the collection box through the conduit. Optionally, the return conduit can be installed inside the inner tube 12. That is, one end of the conduit is connected to the return chamber 142, and the other end is connected to the collection box via the inner tube 12. Understandably, the inner tube 12 also has a return channel. One end of the return channel is connected to the return chamber 142, and the other end is connected to the conduit of the collection box.
[0053] In other implementation scenarios, the liquid storage device 2 and the collection device 3 may also employ other existing technologies.
[0054] In one embodiment, the outer wall of the drive member 6 is provided with scales or marks, which facilitate precise display and adjustment of the depth of the slide tube 13.
[0055] Optionally, the drive unit 6 may be one or more sets. For example, the drive unit 6 may be two sets, with its lower end connected to the slide tube 13 and its upper end extending out to the outer tube 11. The drive unit 6 can drive the slide tube 13 to move up or down.
[0056] In one implementation scenario, a locking member 61 is provided on the outer tube 11 or the driving component 6 to lock and fix the driving component 6. The driving component adopts a sliding rod, and the locking member restricts the movement of the sliding rod. For example, the locking member includes a locking platform with a screw movably mounted on it. When the locking platform is set on the outer tube 11, the movement of the sliding rod can be restricted by abutting the screw against the sliding rod when it needs to be fixed; when the locking platform is set on the sliding rod, the movement of the sliding rod can be restricted by abutting the screw against the outer tube 11 when it needs to be fixed. Of course, the locking member 61 can also adopt other existing structures, as long as it can fix the pushing rod. In another implementation scenario, the driving component 6 can also be directly adopted as an electric telescopic rod.
[0057] This invention, through the arrangement of a first flushing pipe 15 and a second flushing pipe 16, allows liquid to be input into the flushing chamber 141 under normal circumstances (for gentle flushing), i.e., the liquid storage device 2 inputs liquid into the cavity 111, and the liquid enters the first flushing pipe 15 through the second channel 131. When an increased or enhanced flow rate is required (for intensive flushing), intensive flushing can be performed by opening the second flushing pipe 16. Specifically, by operating the drive member 6, the slide tube 13 moves downward until the actuator 53 contacts the seal member 41, releasing the seal member 41 from blocking the second flushing pipe 16. Simultaneously, the slide member 52, under the action of the limiting block 42, pushes the sealing head 51 upward to disengage from the second outlet 134, thereby connecting the second channel 131 with the second flushing pipe 16. During use, this also reduces the risk of feces clogging the flushing hole 143 in the intestines.
[0058] Example 2 like Figure 3 and Figure 4 As shown, this invention application provides a medical enema device. Based on embodiment 1, in this embodiment, the sealing element 41 is an isolation membrane. The actuator 53 is a puncture cone that works in conjunction with the isolation membrane. The lower end of the puncture cone is pointed and can be made of plastic.
[0059] In use, when the piercing cone and the sliding member 52 move downward synchronously with the sliding tube 13, the piercing cone can penetrate the isolation membrane and pierce it, while the sliding member 52 will push the sealing head 51 upward under the action of the limiting block 42, so that the sealing head 51 will be separated from the second outlet 134, thereby realizing the connection between the second channel 131 and the second flushing pipe 16.
[0060] Example 3 This invention application provides a medical enema device, which is based on embodiment 1 and refers to... Figure 1 and Figure 7 As shown, in this embodiment, the second flushing pipe 16 includes, from top to bottom, an inlet section 161, a flared section 162, and a straight section 163. The flared section 162 is located between the inlet section 161 and the straight section 163, and the diameter of the flared section 162 is larger than that of the inlet section 161.
[0061] Optionally, the flared section 162 is recessed into the pipe wall, and a groove is provided outwardly in the pipe wall between the inlet section 161 and the straight section 163, forming the flared section 162. Optionally, the groove is arc-shaped, which can also be understood as the flared section 162 expanding outward from one end of the inlet section 161, and the flared section 162 also expanding outward from one end of the straight section 163. The straight section 163 has the same diameter as the inlet section 161.
[0062] Furthermore, the sealing assembly 4 includes: a seal 41, a limiting block 42, a sleeve 43, a connecting rod 412, and a first elastic member 44.
[0063] In this embodiment, the sealing element 41 includes a sealing seat 411 and a connecting rod 412. The sleeve 43 is fixed to the upper part of the straight section 163 by a bracket. The lower end of the sealing seat 411 is slidably connected to the sleeve 43 through the connecting rod 412, and a first elastic element 44 is connected between the bottom of the connecting rod 412 and the bottom of the sleeve 43. The limiting block 42 is fixed to the inner wall of the inlet section 161. The upper and lower ends of the sealing seat 411 are tapered. Specifically, the middle section of the sealing seat 411 is horizontal, and its upper and lower ends are tapered, that is, the tapered structure is set to converge from one end of the horizontal structure to the other end. In the initial state, the upper tapered structure is located inside the inlet section 161, and the horizontal structure is attached to the inner wall of the inlet section 161.
[0064] Optionally, a sealing ring can be installed in the horizontal middle section of the sealing seat 411 to better fit the inner wall of the inlet section 161 and ensure its sealing performance. The actuator 53 is used in conjunction with the sealing seat 411. Specifically, the actuator 53 includes a push rod and a push block. The upper end of the push rod is connected to the slide tube 13, and the lower end is connected to the push block. The push block is adapted to the top of the sealing seat 411.
[0065] In use, the actuator 53 and the sliding member 52 move synchronously with the movement of the slide tube 13. When the slide tube 13 drives it to move downward, the actuator 53 can contact the sealing seat 411 and push the sealing seat 411 to move towards the flared section 162. That is, in the initial state, the sealing seat 411 is attached to the inner wall of the inlet section 161 and blocks it under the action of the first elastic member 44. When the sealing seat 411 moves downward under force, the inlet section 161 and the flared section 162 are connected. At the same time, since the sliding member 52 also moves synchronously, when the sliding member 52 moves downward and contacts the limiting block 42, the sliding member 52 will push the sealing head 51 upward under the action of the limiting block 42 to make it disengage from the second outlet 134, thereby connecting the second channel 131 with the second flushing pipe 16.
[0066] In this embodiment, the first elastic element 44 cooperates with the sealing seat 411, making it more flexible in use. When the second flushing pipe 16 does not need to be connected, the sealing seat 411 blocks the inlet section 161. When it is necessary to increase the liquid flow rate, the sealing seat 411 can be moved to the flared section 162 to connect the pipe. Compared with embodiment 2, this method allows for repeated adjustment of the opening and closing of the second flushing pipe 16. In use, the liquid flow rate can be intermittently adjusted by controlling the opening and closing of the second flushing pipe 16, making it more flexible and convenient. By intermittently increasing the flow rate, a stronger flushing force can also be generated. At the same time, by adjusting the downward position of the sealing seat 411, the opening degree of the second flushing pipe 16 can be adjusted, thereby adjusting the liquid volume in the second flushing pipe 16 and thus adjusting the overall flow rate.
[0067] Example 4 This invention application provides a tube head for the above-mentioned medical enema device. In this embodiment, reference is made to... Figure 1 and Figure 8 As shown, the tube head 14 has a conical structure.
[0068] Optionally, the large end of the tube head 14 is integrally formed with the outer tube 11. Multiple flushing holes 143 are provided, spaced apart along the outer wall of the tube head and connected to the flushing chamber 141. Multiple flushing holes 143 facilitate the dispersion of liquid flow and enhance the flushing effect.
[0069] Optionally, the small end of the tube head 14 is provided with an arc protrusion, and a flushing hole 143 is also provided on the arc protrusion.
[0070] Optionally, multiple reflux holes 144 are provided, and the multiple reflux holes 144 are spaced apart along the outer wall of the pipe head and connected to the reflux cavity 142.
[0071] In this implementation scenario, the return hole 144 and the flushing hole 143 are staggered, that is, multiple flushing holes are distributed in multiple groups on the pipe head 14, and a return hole 144 is provided between two adjacent groups of flushing holes. A collection groove 145 is provided between the return hole 144 and the small end of the pipe head 14, that is, there is a collection groove 145 between two adjacent groups of flushing holes. The collection groove 145 facilitates the recycling of waste.
[0072] Example 5 This invention application provides a medical enema device, which, based on any of the above embodiments, such as... Figure 1-8 As shown, in this embodiment, the medical enema device also includes an air bladder 7 disposed outside the outer tube 11.
[0073] The outer diameter of the slide tube 13 is adapted to the inner diameter of the inner tube 12 and is slidably and sealingly connected to the inner tube 12. The outer diameter of the inner tube 12 is adapted to the inner diameter of the outer tube 11, thereby forming a sealed cavity 112 on the outside of the slide tube 13 between the connecting ring 132 and the top of the inner tube 12. The airbag 7 is located on the wall of the outer tube 11 connected to the outside of the inner tube 12. A third channel 122 is provided on the inner tube 12 to connect the cavity 112 and the airbag 7.
[0074] Optionally, there may be multiple third channels 122, which are evenly distributed on the inner tube 12.
[0075] In use, when the slide tube 13 moves downward under the drive of the drive member 6, as the connecting ring 132 moves, the air in the cavity 112 enters the airbag 7 through the third channel 122, causing the airbag 7 to inflate. The airbag 7 prevents liquid from flowing out, achieving a leak-proof effect and effectively preventing dirt in the rectum from flowing out through gaps. The inflation and deflation of the airbag 7 can be achieved simultaneously through the formed third channel 122.
[0076] As an implementation scenario, in this scenario, for example, the driving component 6 is provided with a first mark and a second mark (not shown in the figure). When the driving component 6 pushes the slide tube 13 downward to the first mark, the slide tube 13 is at a first depth. At this depth, the slide tube 13 is still above the second flushing tube 16, but some air in the cavity 112 can enter the airbag 7 through the third channel 122. The airbag 7 will inflate to a predetermined size to prevent leakage. When it is necessary to open the second flushing tube 16, the driving component 6 pushes the slide tube 13 downward to the second mark. At this depth, the slide tube 13 is at a second depth. At this depth, the actuator 53 at the bottom of the slide tube 13 will puncture or push the seal 41 to release the seal on the second flushing tube 16, so that the liquid in the second channel 131 simultaneously enters the flushing chamber 141 through the first flushing tube 15 and the second flushing tube 16. When the slide tube 13 is moved upward back to the initial position after use, the internal airflow can smoothly return to the cavity 112. The airbag is made of a material with high elastic modulus and durability. When the slide tube 13 moves to the first depth position, it can be adjacent to the second flushing tube 16. In this way, when the slide tube 13 moves from the first depth to the second depth, the air entering the airbag has little impact on the change in its internal pressure. When the sealing element 41 adopts a sealing seat structure, the opening degree of the second flushing tube 16 or the intermittent start of the second flushing tube 16 can be controlled by adjusting the position of the slide tube 13 during use. For example, when the slide tube 13 is at the second depth, the second flushing tube 16 is not fully open, that is, the horizontal structure of the sealing seat 411 has just moved out of the inlet section 161 and is still located at the upper part of the flared section 162. When the slide tube 13 continues to move down to the third depth, the second flushing tube 16 is fully open, that is, the horizontal structure of the sealing seat 411 is located at the middle position of the flared section 162. After the slide tube 13 has been flushed at the second or third depth for a certain period of time, it can be moved upward back to the first depth. At this time, the second flush tube 16 is in the closed state, and the first flush tube 15 is used to continue the enema operation.
[0077] Optionally, the airbag 7 may be equipped with a deflation valve or an inflation valve, with an inflation device connected to the inflation valve. When the airflow into the airbag 7 is insufficient, i.e., when the airbag 7 is too small and does not reach the predetermined target, the inflation device can be used to supplement the airflow. When the internal pressure is too high and the airbag volume is too large, a certain amount of air can be released through the deflation valve.
[0078] Optionally, the airbag 7 is equipped with a pressure sensor for sensing airbag pressure. The pressure sensor is electrically connected to a control element, which receives the pressure data sensed by the pressure sensor and displays it through a display module. The displayed pressure value allows for convenient control of the airbag 7's volume, facilitating its use. During use, the initial volume of the airbag 7 and the initial position of the sliding tube 13, i.e., the size of the cavity, can be adaptively adjusted according to the pressure value of the pressure sensor. For example, at the initial position of the sliding tube, the initial airbag volume is A; when the sliding tube moves to the first depth and / or the second depth, the airbag volume is A+B, ensuring that the airbag can prevent liquid leakage without affecting patient comfort. The specific setting method is not limited here and can be adaptively designed according to the size of the tube and the airbag.
[0079] Example 6 This invention application provides a medical enema device, which is based on embodiment 5 and refers to... Figure 1 and Figure 5 As shown, in this embodiment, a baffle 123 is movably disposed on the third channel 122. Specifically, the inner tube 12 located on one side of the third channel 122 has an installation groove. One end of the baffle 123 is slidably connected to the installation groove through a second elastic member 124, and the other end of the baffle 123 extends into the first channel 121 inside the inner tube 12. A flow hole 1231 is provided on the baffle 123. The flow hole 1231 can coincide with or be offset from the third channel 122. When it coincides with the third channel 122, the third channel 122 is in a flow state. When it is offset, the flow of the third channel is blocked.
[0080] Optionally, the baffle 123 has a rounded end inside the inner tube 12, and the inner tube 12 corresponding to the mounting groove has a sliding groove for the baffle 123 to slide in a sealing manner. The sliding groove is adapted to the baffle and the rounded end of the baffle. The inner wall of the sliding groove is provided with a sealing structure.
[0081] In one implementation scenario, when the driving component 6 pushes the slide tube 13 downward to the first mark, the slide tube 13 is at a first depth. This first depth is when the bottom wall of the slide tube 13 is above the round head of the baffle 123, and the sliding component 52 is located on one side of the round head. That is, when the slide tube 13 is in the position between the initial position and the first depth (including the first depth), the third channel 122 is in a flowing state. When it is necessary to open the second flushing tube 16, as the driving component 6 pushes the slide tube 13 to continue moving to the second depth, the slide tube 13 will push the round head of the baffle 123 to move towards the third channel 122. The baffle 123 exerts pressure on the second elastic component 124 until the flow hole 1231 on the baffle 123 is placed in the mounting groove. At this time, the flow hole 1231 is misaligned with the third channel 122, and the baffle 123 closes the third channel 122. Simultaneously, the slide tube 13 reaches the second depth, and the actuator 53 at its bottom punctures or pushes the seal 41 to release it from the seal on the second flushing tube 16. The liquid in the second channel 131 then enters the flushing chamber 141 through the second flushing tube 16. After use, when the slide tube returns to its initial position or the first depth position, the baffle 123 returns to its initial state under the action of the second elastic member 124, that is, the third channel 122 is in a flowing state, and the airflow inside the airbag 7 can also smoothly return to the cavity 112.
[0082] When the sealing element 41 adopts a sealing seat structure, the opening degree of the second flushing pipe 16 can be adjusted or the second flushing pipe 16 can be intermittently started by adjusting the position of the sliding pipe 13 during use. For example, when the sliding pipe 13 is at the second depth, the second flushing pipe 16 is not fully open, that is, the horizontal structure of the sealing seat 411 has just moved out of the inlet section 161 and is still located at the upper part of the flared section 162. When the sliding pipe 13 continues to move down to the third depth, the second flushing pipe 16 is fully open, that is, the horizontal structure of the sealing seat 411 is located at the middle position of the flared section 162. At the same time, after flushing at the second or third depth for a certain period of time, the sliding pipe 13 can move upward back to the first depth. At this time, the second flushing pipe 16 is in the closed state, and the first flushing pipe 15 continues to be used for enema operation. This achieves intermittent enhancement of flow rate, which can be adjusted according to actual needs. Intermittent enhancement of flow rate can also generate stronger flushing force.
[0083] In another implementation scenario, when the slide tube 13 is at the first depth, the flow hole 1231 can be offset from the third channel 122. When the slide tube 13 continues to move to the second depth, the air in the cavity 112 can be discharged through a separately provided buffer space. Specifically, a compressible buffer space is provided in the cavity 112 to accommodate excess air generated when the slide tube 13 continues to move downward. When the baffle 123 blocks the air from entering the airbag 7, the excess air generated when the slide tube 13 continues to move downward enters the buffer space. The buffer space absorbs the excess air to avoid excessive pressure. When the slide tube 13 returns to its initial position, the buffer space releases the air and returns to the cavity. The buffer space utilizes existing technologies, such as elastic diaphragms or airbags. For example, an elastic diaphragm divides cavity 112 into a main cavity and a buffer cavity. The main cavity is connected to the third channel 122, and the buffer cavity is connected to the main cavity through a small hole to accommodate excess air. When the slide tube moves downward, the air in the main cavity is forced into the airbag 7 through the third channel 122. When the slide tube 13 contacts the baffle 123 and pushes the baffle 123 to close the third channel 122, if the slide tube 13 needs to continue moving downward, the excess air enters the buffer cavity through the small hole, and the elastic diaphragm expands. When the slide tube moves upward, the volume of the main cavity increases, the elastic diaphragm contracts, and the air in the buffer cavity is forced back into the main cavity. In the design, the pressure difference control principle can be used. For example, the pressure generated by the downward movement of the slide tube 13 causes air to preferentially enter the airbag 7. When the baffle 123 closes the third channel, the pressure inside cavity 112 increases, and only then will air enter the buffer cavity.
[0084] In this embodiment, the opening and closing of the third channel 122 is controlled by the added baffle 123. When the flushing tube is flushing, the baffle 123 can effectively prevent the airflow in the airbag 7 from flowing back into the cavity, thereby affecting the stability of the slide tube 13. Of course, the pressure of the driving component 6 can also ensure the stability of the slide tube 13, but the dual action of the baffle 123 and the driving component 6 further ensures its stability.
[0085] Example 7 In actual use, each sliding part is equipped with a sealing structure, such as between the connecting ring 132 and the inner wall of the outer tube 11, and between the sliding tube 13 and the inner tube 12. The sealing structure can be made of rubber.
[0086] As a preferred implementation scenario, refer to Figure 1 and Figure 6As shown, in this scenario, a sealing structure 17 is provided between the connecting ring 132 and the inner wall of the outer tube 11. This sealing structure 17 includes a sealing layer 171 and a fixing layer 172. The sealing layer 171 has a U-shaped structure, with its upper and lower layers embedded in the upper and lower surfaces of the connecting ring 132, respectively. The fixing layer 172 is disposed within the inner groove of the sealing layer 171, and an annular groove is formed on the outer side of the connecting ring 132, within which the fixing layer 172 is engaged. A groove is formed on the sealing layer 171 on the side away from the fixing layer 172. This groove reduces the frictional force between the sealing structure and the inner wall of the outer tube 11 when the sliding tube 13 moves, thereby reducing the pulling force required to move the sliding tube 13.
[0087] Optionally, protrusions can be provided on both sides of the fixing layer 172, and correspondingly, a groove is provided in the annular groove to accommodate the protrusions. This ensures the stability of the sealing structure and ensures that the slide tube 13 has strong stability even after multiple slidings.
[0088] Optionally, medical lubricant can be applied to the inner walls of the outer tube 11 and the inner tube 12 to ensure good sliding performance of the slide tube 13 during use.
[0089] Example 8 This invention application provides a medical enema device, see reference. Figure 1 As shown, in this embodiment, the medical enema device further includes a filter assembly 8 disposed above the slide tube. The filter assembly 8 includes a partition 81 and a second filter screen 83.
[0090] A partition 81 is movably disposed within the cavity 111 above the slide tube 13. The partition 81 is connected to the outer wall of the drive component 6, i.e., a connection hole is provided on the partition 81, and the outer wall of the drive component 6 located in the cavity 111 is connected to this connection hole. The outer wall of the partition 81 is in a sealed sliding fit with the inner wall of the outer tube 11, i.e., the partition 81 can move synchronously with the drive component 6. The partition 81 divides the cavity 111 from top to bottom into a heating chamber and a filtering chamber. A heating element and a temperature sensor are provided on the heating chamber. The heating element is used to heat the liquid in the heating chamber, and the temperature sensor monitors the temperature of the liquid in real time. The heating element is not shown in the figure, but uses existing technology, such as a heating element embedded in the wall of the outer tube 11. In use, both the temperature sensor and the heating element can be electrically connected to the control element to facilitate the stable control of the liquid at 36°C~38°C, with a target temperature preferably of 37°C. By setting a heating chamber inside the cavity, when dealing with temporarily added liquids (which are usually too cold), the liquids can be heated directly, so that the overall temperature can be controlled within a suitable range after the addition of new liquids.
[0091] In one embodiment, the filter assembly 8 further includes a first filter screen 82 disposed above the slide tube 13.
[0092] Specifically, a fixed platform 135 is fixedly installed at the top of the slide tube 13. A circular hole is opened in the middle of the fixed platform 135, which is connected to the cavity 111 and the second channel 131. The first filter screen 82 is connected to the fixed platform 135 and covers the circular hole. The lower end of the driving member 6 is connected to the fixed platform 135, and the sliding tube 13 and the first filter screen 82 at its top are moved under the drive of the driving member 6.
[0093] Optionally, the first filter screen 82 has a U-shaped or arched structure, with its open end fixed to the mounting platform 135. The arched or U-shaped design can increase the filtration area and improve the filtration effect.
[0094] In one embodiment, a third elastic element 136 is fitted onto the slide tube 13 located within the cavity 112. In this embodiment, the driving element 6 is a sliding rod, and a locking element 61 for locking and fixing the sliding rod is provided on the upper end of the outer tube 11 or on the sliding rod. In use, by applying pressure to the sliding rod, the sliding rod pushes the fixed platform 135 and the slide tube 13 downward. When it moves to the designated position, the locking element 61 positions the sliding rod, making the slide tube 13 positioned at the designated depth. After use, the locking element 61 is released, i.e., the external force on the sliding rod is released. At this time, under the action of the third elastic element 136, the slide tube 13 will be pushed back to the initial position quickly. At the same time, it can also be coordinated with the deflation of the airbag 7 to make it return to its original position quickly. By setting the third elastic element 136, not only can the slide tube 13 return to its position quickly, but when the third elastic element 136 rebounds and releases the pressure, it will cause the first filter screen 82 above the slide tube 13 to vibrate, which can effectively remove impurities or particles attached to the first filter screen 82, ensure smooth liquid flow, and extend service life.
[0095] Optionally, the second filter screen 83 has a cylindrical structure and is fixed above the first filter screen 82 by a support rod (not shown in the figure), and the upper end of the second filter screen 83 has a sealing head 84. A through hole is provided in the middle of the partition plate 81, and the size of the through hole is adapted to the diameter of the cylindrical second filter screen 83, so that the partition plate 81 can slide along the second filter screen 83 during the up and down movement.
[0096] In use, liquid is first introduced into the heating chamber of cavity 111 through the liquid storage device 2. After the liquid enters the heating chamber, the heating element heats the liquid. When the target temperature is reached, the driving component 6 is operated to move it downward. At this time, the partition 81 will move downward synchronously with the push rod. Since the second filter screen 83 is fixedly set, the partition 81 slides along the second filter screen 83 through the through hole. When the partition 81 moves a certain distance away from the sealing head 84, the liquid in the heating chamber enters the lower filter chamber through the second filter screen 83.
[0097] This embodiment not only allows for the heating of liquids before use, but also enables convenient and rapid control of liquid flow through the cooperation of the partition 81, the second filter screen 83, and the sealing head 84. Furthermore, in conjunction with the first filter screen 82, it achieves double filtration, ensuring effective filtration. A sealing ring can be installed on the inner wall of the through-hole. As the partition 81 moves downward, the sealing ring can scrape the second filter screen 83 to remove impurities or particles adhering to it, ensuring smooth liquid flow.
[0098] The initial setting position of the partition 81 can be set as needed. For example, in one implementation scenario, the partition 81 is adapted to the first depth required by the slide tube 13, that is: when the driving component 6 moves the slide tube to the first depth position, the heating chamber and the filtering chamber are in a connected state, and the airbag 7 is also in an inflated state.
[0099] It should be noted that the positions of components such as partition 81, slide tube 13 and filter screen in the accompanying drawings of this invention are only schematically shown. Their specific positions can be adjusted according to the length of outer tube 11. The size and length of each component are also schematic and are only used to express the concept of this technical solution. They do not involve the limitation of specific positions and sizes in actual embodiments.
[0100] Example 9 This invention application provides a method for using a medical enema device, which is any one of the enema devices described in Examples 1-8, specifically including the following steps: Step S1: Liquid is introduced into the heating chamber of cavity 111 through liquid storage device 2; In step S2, the liquid is heated in the heating chamber by the heating element. When the target temperature is reached, such as 37°C, the heating element is turned off.
[0101] In step S3, the drive unit 6 is operated to apply downward pressure to the slide tube 13, causing the slide tube 13 to be positioned at a specified first depth. During this process, the partition 81 moves downward synchronously, moving away from the sealing head 84, thereby allowing the liquid in the heating chamber to enter the filtering chamber through the second filter screen 83; the air in the cavity 112 enters the air bladder through the third channel 122, and the air bladder, after being inflated, can prevent the liquid from flowing out.
[0102] In step S4, the locking member 61 is operated to fix the driving member 6, so that the slide tube 13 is held at the first depth. The liquid entering the filter chamber is filtered by the first filter screen 82 and then enters the second channel 131. At the first depth, the liquid entering the second channel 131 enters the flushing chamber 141 through the first flushing pipe 15.
[0103] In one embodiment, step S5 is further included, in which the locking member 61 is operated to release the fixation of the driving member 6, and the locking member continues to apply downward pressure to the slide tube 13, so that the slide tube 13 is located at a specified second depth position. At this time, the second channel 131 is connected to the second flushing tube 16, so that the liquid in the second channel 131 enters the flushing chamber 141 through two paths.
[0104] In one embodiment, when it is necessary to return from the second depth position to the first depth position, the sealing assembly 4 adopts the structure described in embodiment 3. By releasing the locking member 61, the slide tube 13 is returned to the first depth position and then fixed. At this time, the sealing seat 411 is sealed on the inlet section of the second flushing tube 16.
[0105] After use, operate the locking element 61 to release the fixation of the driving element 6, and the slide tube 13 returns to its initial position. During rinsing, the collecting device 3 includes a rubber bladder, the output end of which is connected to the return chamber 142 via a conduit. In use, under the action of the collecting device, the liquid in the return chamber 142 enters the collecting device 3 for collection. The first depth position can be precisely controlled by a mark or scale set on the push rod.
[0106] In one embodiment, in step S1, the liquid storage device 2 is preferably a liquid storage tank connected to the cavity 111 via a conduit. An intelligent pump is installed on the conduit. The intelligent pump enables precise control of pressure and flow rate, facilitating real-time monitoring and adjustment. During use, the output pressure of the pump is adjusted to ensure the pressure of the enema fluid remains within a safe range. The flow rate can also be adjusted as needed. For example, when only the first flushing pipe 15 is used for ordinary flushing, the pumped pressure can be 5-8 kPa. When the second flushing pipe 16 is simultaneously activated, the pumped pressure increases to 8-11 kPa. The pump adaptively adjusts in real time according to the activation status of the second flushing pipe 16. The output pressure of the pump is not limited here and can be adjusted according to different usage scenarios.
[0107] Furthermore, in one embodiment, a sensor can be installed on the limiting block 42. This sensor, along with the pump body, is electrically connected to the control element. When the sliding member 52 abuts against the limiting block 42, the sensor transmits communication data to the input terminal of the control element. Upon receiving the signal, the control element adjusts the pump body, increasing the output pressure. When the sliding member 52 is not in contact with the limiting block 42, the pump body automatically switches to normal pressure mode. The sensor is not shown in the diagram and can be an existing pressure sensor.
[0108] In one embodiment, the medical enema device also includes a viewing mirror. The viewing mirror allows for real-time observation of the enema tube entering the intestine during operation, and also helps doctors adjust the flushing pressure promptly based on intestinal issues, improving the safety and accuracy of the enema procedure. The viewing mirror is not shown in the diagram and uses existing technology. For example, the viewing mirror can be a miniature camera, whose installation position and angle can be carefully designed to observe different parts and changes in the intestine, such as at the front end of the tube head, or on the side wall of the tube head. Multiple miniature LEDs can be installed around the viewing mirror to provide uniform illumination. Data transmission can be wireless, transmitting image data to an external display via a wireless module, or via cable. When using a cable, a viewing channel for the viewing mirror can be formed inside the enema tube. For example, a viewing channel is formed between the inner tube and the tube head, with one end of the viewing channel on the inner tube connected to a branch tube. The viewing mirror extends into the tube head through the branch tube and the viewing channel.
[0109] In another usage method, the driving component 6 is directly selected as an electric telescopic rod. That is, in this embodiment, there is no need to operate the locking component; the slide tube 13 can be moved downward or upward simply by adjusting the extension or retraction of the driving component 6. In one embodiment, the liquid storage device 2 is preferably a liquid storage tank connected to the cavity 111 through a conduit. An intelligent pump body is provided on the conduit. The difference is that, in this scenario, the limit block 42 does not need to be equipped with a sensor. The electric telescopic rod is electrically connected to the control element. In this way, when the electric telescopic rod extends and pushes the slide tube 13 to the second depth position, the output pressure of the pump body automatically switches from normal pressure to high pressure. When the electric telescopic rod is in the initial state or the slide tube 13 is placed in the first depth position, the output pressure of the pump body is in the normal pressure state.
[0110] In the foregoing, only certain exemplary embodiments have been briefly described.
