Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a laxative care device for patients with constipation in the gastroenterology department. Background Technology

[0002] Constipation is a common condition in gastroenterology clinical nursing that significantly impacts patients' quality of life, especially among elderly, postoperative, and chronically ill patients. Constipation not only leads to difficulty in defecation but can also cause discomfort such as bloating, abdominal pain, and anal pain. In severe cases, it can even cause complications such as intestinal obstruction and fecal impaction.

[0003] Existing laxatives typically employ a crushing mechanism to process stool for easier passage. The basic principle is to mechanically break down hardened stool into smaller particles, thereby reducing resistance during defecation. However, during insertion of the crushing mechanism, the relatively rigid front end may push the stool back, causing it to accumulate in the rectum and actually worsening constipation. This back-pushing phenomenon not only affects the efficiency of stool passage but may also cause fear in the patient, affecting their cooperation with subsequent care. Summary of the Invention

[0004] This invention provides a laxative device for patients with constipation in the gastroenterology department, which solves the technical problem that existing crushing mechanisms push the feces back during insertion, causing feces to accumulate in the rectum and aggravating constipation symptoms.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A bowel-regulating care device for patients with constipation in the gastroenterology department includes a cylindrical body with an expander mounted on it. The expander has a receiving groove containing an elastic sleeve. A pushing mechanism is mounted on the cylindrical body, with its output end contacting the elastic sleeve. In a first working state, the pushing mechanism is in a position where the elastic sleeve is located within the receiving groove. In a second working state, the elastic sleeve is pushed into the patient's intestine by the output end of the pushing mechanism. In a third working state, the output end of the pushing mechanism is retracted, and the elastic sleeve is located within the patient's intestine and envelops the feces. A crushing mechanism is mounted on the cylindrical body, with an adjustable angle between the crushing mechanism and the axis of the cylindrical body. The crushing mechanism crushes the feces.

[0007] Optionally, a shrink ring is installed on one side of the elastic sleeve at the opening of the receiving groove. Both the elastic sleeve and the side wall of the cylinder have a double-layer structure. The ejection mechanism includes a first annular plate and an annular pressure plate disposed inside the side wall of the cylinder. A sliding groove is formed on the surface of the cylinder. Parts of the first annular plate and the annular pressure plate protrude out of the cylinder through the sliding groove. A groove is formed inside the first annular plate. Multiple sets of annularly distributed push rods are installed on the surface of the first annular plate. One end of each push rod penetrates into the side wall of the elastic sleeve. The push rod is hollow and each push rod is provided with a connecting rope. One end of each connecting rope is fixedly connected to the shrink ring. The other end of each connecting rope is located inside the groove. One side of the annular pressure plate is located on the inner wall of the groove and presses the connecting rope. The surface of the annular pressure plate is connected to the first annular plate by insert connecting bolts.

[0008] Optionally, the chute and push rod are both arranged along the axis parallel to the cylinder and the expander.

[0009] Optionally, the crushing mechanism includes a connecting rod and a spiral drill bit. The connecting rod movably passes through the closed end of the cylinder. The closed end of the cylinder is provided with an angle adjustment mechanism for adjusting the angle of the connecting rod. The spiral drill bit is fixedly installed at the end of the connecting rod located inside the cylinder, and an installation component is provided at the end of the connecting rod located outside the cylinder.

[0010] Optionally, the mounting component includes a mounting base fixedly mounted on one end of the connecting rod located outside the cylinder. The mounting base is plugged into the output end of the external rotating mechanism, and a fixing bolt is socketed on the mounting base. The fixing bolt is perpendicular to the plugging direction between the mounting base and the output end of the external rotating mechanism.

[0011] Optionally, the angle adjustment mechanism includes a circular groove formed at the closed end of the cylinder, a second annular plate and a connecting socket are provided inside the circular groove, the connecting socket is I-shaped along its axial section, the outer edge of the second annular plate is fixedly connected to the inner surface of the circular groove, the inner edge of the second annular plate is disposed between the two side plates of the connecting socket, a flexible membrane is fixedly connected between the two side plates of the connecting socket and the second annular plate, and the connecting rod movably passes through the center of the connecting socket.

[0012] Optionally, the outer diameter of the two side plates of the connecting socket is smaller than the inner diameter of the circular groove, but larger than the inner diameter of the second annular plate.

[0013] Optionally, the end of the cylinder is provided with a collection box and a handle, the collection box being used to collect crushed or ejected feces.

[0014] Optionally, a brush plate is fixedly connected to the inner surface of the cylinder, the brush plate is located above the collection box, and the brush bristles of the brush plate contact the connecting rod or the auger bit.

[0015] Optionally, the outer wall of the expander is provided with multiple anti-slip protrusions, and the expander is arranged in a wave-like or sawtooth shape to increase friction; the outer surface of the elastic sleeve is coated with a medical lubricant, which is a water-soluble or silicon-based material.

[0016] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0017] In the above solution, a receiving groove is set inside the expander, and a double-layered elastic sleeve is installed in the receiving groove. A push rod is set inside the elastic sleeve, and in conjunction with the linkage of the ejection mechanism, the feces in the intestine are effectively wrapped and fixed. During insertion, the elastic sleeve unfolds and fits against the intestinal wall under the action of the push rod, and then contracts after being ejected by the ejection mechanism, wrapping the feces inside. This effectively prevents the feces from being pushed back into the deep intestine during the crushing process, thus avoiding aggravating constipation symptoms.

[0018] By incorporating a crushing mechanism, the auger bit rotates and advances under power or manual operation, penetrating deep into hardened fecal masses. Through rotational shearing, it breaks the feces into smaller particles. This process significantly reduces the overall volume and hardness of the feces, making it easier to expel. After crushing the feces, the auger bit also carries the crushed feces out of the body during its withdrawal. This function is achieved through the structural characteristics of the auger bit: its helical blades have a pushing effect as they rotate and withdraw, effectively reducing fecal residue, preventing re-accumulation or blockage, and improving bowel movement efficiency.

[0019] By setting a brush plate on the inner surface of the cylinder, the brush bristles of the brush plate can contact the connecting rod or the auger bit, automatically cleaning the surface residue during the rotation of the crushing mechanism, thus ensuring the crushing effect of the auger bit.

[0034] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figures 1-4 As shown, an embodiment of the present invention provides a laxative device for patients with constipation in the gastroenterology department, including a cylindrical body 1 and a dilator 2. The dilator 2 is disposed at the insertion end of the cylindrical body 1. The dilator 2 includes a dilator 2, which is configured as an annular tube for dilating the anus. In practical applications, the outer wall of the dilator 2 can be provided with multiple anti-slip protrusions, which are arranged in a wavy or serrated shape. The main function of these protrusions is to increase the friction between the dilator and the intestinal wall during dilation, thereby improving the stability of dilation, preventing the dilator 2 from sliding during operation, and ensuring the dilation effect. Figure 3 As shown. The inner wall of the expander 2 is provided with a receiving groove 21, and an elastic sleeve 22 is provided inside the receiving groove 21. A contraction ring 23 is installed on the side of the elastic sleeve 22 located at the opening of the receiving groove 21. The outer surfaces of both the elastic sleeve 22 and the contraction ring 23 are coated with a medical lubricant, which is a water-soluble or silicone-based material. The purpose is to reduce frictional resistance with intestinal tissue during insertion, making it easier for the device to enter the body, improving the smoothness of operation, and reducing the risk of irritation and damage to patient tissues. The nursing device in this embodiment also includes a crushing mechanism 3, which can enter the intestine through the expander 2 to crush feces.

[0036] like Figure 4As shown, a pushing mechanism 4 is installed on the cylinder 1. In the first working state, the elastic sleeve 22 is located in the receiving groove 21. In the second working state, the elastic sleeve 22 is pushed into the patient's intestine by the output section of the pushing mechanism 4. In the third working state, the output end of the pushing mechanism 4 is retracted, and the elastic sleeve 22 is located in the patient's intestine and encloses the feces. Both the elastic sleeve 22 and the side wall of the cylinder 1 are double-layered structures. The pushing mechanism 4 includes a first annular plate 41 and an annular pressure plate 46 disposed within the side wall of the cylinder 1. A sliding groove 42 is formed on the surface of the cylinder 1. Parts of component 6 protrude from the cylinder 1 through the groove 42. A groove 45 is formed within the first annular plate 41. Multiple sets of annularly distributed push rods 43 are mounted on the surface of the first annular plate 41. One end of each push rod 43 penetrates into the side wall of the elastic sleeve 22. Each push rod 43 is hollow and contains a connecting rope 44. One end of each connecting rope 44 is fixedly connected to the contraction ring 23, and the other end is located within the groove 45. One side of the annular pressure plate 46 is located on the inner wall of the groove 45 and presses against the connecting rope 44. The surface of the annular pressure plate 46 is connected to the first annular plate 41 via insert bolts 47. The groove 42 and push rods 43 are arranged parallel to the axis of the cylinder 1 and the expander 2. This arrangement allows the push rods 43 to move along the axis under the drive of the push mechanism 4, thereby driving the elastic sleeve 22 along the intestinal wall into the rectum.

[0037] In this embodiment, the contraction ring 23 has a stronger contraction capacity than the elastic sleeve 22, and can effectively clamp the feces. In the first and second working states, the annular pressure plate 46 in the push mechanism 4 presses tightly against the connecting rope 44, the connecting rope 44 is taut, the push rod 43 abuts against the surface of the contraction ring 23, and the contraction ring 23 is in an expanded state.

[0038] In use, the dilator 2 is first inserted into the patient's anus to dilate it. Then, the operator pushes the first annular plate 41 along the groove 42 towards the dilator 2. The first annular plate 41 is connected to the push rod 43, causing the push rod 43 to move inward simultaneously. Because the push rod 43 has a certain rigidity, during its movement, it causes the elastic sleeve 22 to expand, conforming to the intestinal wall and enveloping the feces. As the push rod 43 moves the elastic sleeve 22 inward along the intestinal wall, the force applied by the push rod 43 is relatively small; it mainly guides the elastic sleeve 22 to conform to the intestinal wall and smoothly envelop the feces, rather than applying a large pushing force to the feces. This effectively avoids pushing the feces back into the intestines, ensuring that the elastic sleeve 22 can smoothly fit over the feces.

[0039] When the device reaches the appropriate insertion depth, the operator needs to move the push rod 43 back. First, loosen the connecting bolt 47 and pull out the annular pressure plate 46. One end of the connecting rope 44 loses the restriction of the annular pressure plate 46, that is, the contraction ring 23 loses the pull of the connecting rope 44. The contraction ring 23 changes from an expanding state to a contracting state, clamping the feces. At this time, the user moves the first annular plate 41 back, driving the push rod 43 back, causing the push rod 43 to move out of the elastic sleeve 22. The elastic sleeve 22 loses the support of the push rod 43 and contracts, wrapping the feces and preventing the feces from being pushed back or overflowing during the crushing process. During the retraction of the push rod 43, due to the clamping and positioning effect of the contraction ring 23, the push rod 43 will not drive the elastic sleeve 22 and the contraction ring 23 out.

[0040] In this embodiment, by setting the push-out mechanism 4, the elastic sleeve 22 and the push rod 43 to work together, the elastic sleeve 22 is stably inserted and the feces in the intestine are effectively wrapped, thereby preventing the feces from being pushed back during the subsequent crushing process, and improving the efficiency and safety of bowel care.

[0041] like Figure 2 and Figure 5 As shown, the crushing mechanism 3 includes a connecting rod 31 and a spiral drill bit 32. The connecting rod 31 movably passes through the closed end of the cylinder 1. The closed end of the cylinder 1 is provided with an angle adjustment mechanism 5, which is used to adjust the angle of the connecting rod 31. The spiral drill bit 32 is fixedly installed at one end of the connecting rod 31 located inside the cylinder 1. The end of the connecting rod 31 located outside the cylinder 1 is provided with a mounting component. The mounting component includes a mounting seat 33 fixedly installed at one end of the connecting rod 31 located outside the cylinder 1. The mounting seat 33 is plugged into the output end of the external rotating mechanism, and a fixing bolt 34 is socketed on the mounting seat 33. The fixing bolt 34 is perpendicular to the plugging direction of the mounting seat 33 and the output end of the external rotating mechanism. The end of the cylinder 1 is provided with a collection box 6 and a handle 7. The collection box 6 is used to collect the crushed or pushed-out feces. A brush plate 8 is fixedly connected to the inner surface of the cylinder 1. The brush plate 8 is located above the collection box 6, and the bristle structure of the brush plate 8 contacts the connecting rod 31 or the spiral drill bit 32.

[0042] In this embodiment, one end of the mounting base 33 is designed to fit the shape of the output end of the external rotating mechanism, such as a cylindrical or square socket, allowing it to be smoothly inserted and remain stable. This plug-in connection facilitates quick installation and disassembly, improving the ease of use of the device. After the mounting base 33 is plugged into the output end of the external rotating mechanism, the fixing bolt 34 is screwed into the mounting base 33 to secure its connection with the external rotating mechanism. The external rotating mechanism is typically an electric or manual drive device that drives the mounting base 33 to rotate via its output end, thereby driving the connecting rod 31 and the auger drill bit 32 to rotate.

[0043] In actual operation, after connecting the connecting rod 31 to the external rotating mechanism using the mounting component, the connecting rod 31 is pushed to move axially along the cylinder 1, allowing the auger drill bit 32 to enter the rectum through the expander 2 and come into contact with the feces. At this time, the external rotating mechanism drives the mounting component, connecting rod 31, and auger drill bit 32 to rotate. When the auger drill bit 32 crushes the feces, its rotational motion drives the feces to move into the cylinder 1. At the same time, through cutting and squeezing, the feces are broken into smaller particles. During the crushing process, the operator can periodically move the connecting rod 31 backward, moving the auger drill bit 32 to the brush plate 8. The bristles of the brush plate 8 come into contact with the surface of the auger drill bit 32. Through rotation or sliding friction, the bristle structure on the brush plate 8 can effectively remove the residue on the surface of the auger drill bit 32. The bristles of the brush plate 8 are usually made of soft, corrosion-resistant materials, such as medical-grade silicone or nylon bristles.

[0044] After the feces are broken down, the elastic sleeve 22 and the contraction ring 23 contract, reducing the diameter of the feces and making it easier to expel. At the same time, after the feces are broken down, the contraction ring 23 further contracts, closing the end of the elastic sleeve 22 to form a pocket-shaped structure. As the elastic sleeve 22 exits the intestine with the expander 2, it can carry the feces out of the body, thereby improving the efficiency of defecation, reducing residue, and improving the nursing effect and patient comfort.

[0045] like Figure 2 , Figure 6 as well as Figure 7 As shown, the angle adjustment mechanism 5 includes a circular groove 51 opened at the closed end of the cylinder 1. The circular groove 51 is provided with a second annular plate 52 and a connecting socket 53. The connecting socket 53 is I-shaped along its axial section. The inner edge of the second annular plate 52 is located between the two side plates of the connecting socket 53. The two side plates of the connecting socket 53 are connected to the second annular plate 52 by a flexible membrane 54. The connecting rod 31 moves through the center of the connecting socket 53. The outer diameter of the two side plates of the connecting socket 53 is smaller than the inner diameter of the circular groove 51 and larger than the inner diameter of the second annular plate 52.

[0046] In this embodiment, the connecting socket 53 has an "I"-shaped axial cross-section structure, and its two side plates are connected to the second annular plate 52 by a flexible membrane 54. This design provides adjustable movement space for the connecting rod 31. When the operator adjusts the angle of the connecting rod 31 through an external mechanism, the connecting rod 31 will deflect around the center of the connecting socket 53. The angle change is limited by the relative dimensions between the two side plates of the connecting socket 53 and the second annular plate 52. Since the outer diameter of the two side plates of the connecting socket 53 is smaller than the inner diameter of the circular groove 51, but larger than the inner diameter of the second annular plate 52, when the connecting rod 31 deflects to a certain angle, the structure of the connecting socket 53 will contact the second annular plate 52 and form a blockage. This blocking effect limits the further deflection of the connecting rod 31, thereby ensuring that its adjustment angle does not exceed a reasonable range, that is, the angle is less than the attached... Figure 6 The design not only achieves flexibility in adjusting the angle of the connecting rod 31, but also effectively prevents the risk of structural instability or damage to the intestines due to excessive angle deflection, thus improving the safety and controllability of the device.

[0047] The size of the β angle can be rationally set according to actual clinical needs and for patients of different body types. In medical applications, considering individual patient differences, such as body size and intestinal curvature, the range of angle adjustment must have a certain degree of adaptability to ensure that the instrument can be flexibly adjusted during operation without causing tissue damage or operational difficulties due to excessive angle. Therefore, the design of the β angle is not fixed but can be optimized and adjusted according to the actual usage scenario. For example, for patients with smaller body size or greater intestinal curvature, the β angle can be appropriately reduced to improve operational safety; while for patients with larger body size or straighter intestinal structure, the β angle can be moderately increased to enhance the adaptability and ease of operation of the instrument.

[0048] In summary, this application aims to solve the technical problem that existing laxative devices tend to push feces deeper into the intestines during the fecal crushing process, thereby exacerbating constipation symptoms. This device integrates multiple functions such as expansion, wrapping, crushing, cleaning, and collection, improving the safety and efficiency of laxative care. First, the device uses an expander 2 to gently expand the anus and rectum. Its outer wall has anti-slip protrusions to increase friction and prevent slippage. Simultaneously, the inner wall of the expander 2 has a receiving groove 21, in which a double-layered elastic sleeve 22 is installed. The outer surface of the elastic sleeve 22 is coated with a medical lubricant to reduce irritation to the intestines during insertion. Inside the elastic sleeve 22 is a push rod 43, which connects to a push-out mechanism 4 inside the cylinder 1. Combined with the linkage of the push-out mechanism 4, effective wrapping and fixation of feces within the intestines is achieved. During insertion, the elastic sleeve 22 unfolds and fits the intestinal wall under the action of the push rod 43, and then contracts when the push mechanism 4 withdraws, wrapping the feces inside, thereby effectively preventing the feces from being pushed back into the deep intestine during the crushing process and avoiding aggravation of constipation symptoms.

[0049] like Figure 2 and Figure 5 As shown, the device is equipped with a crushing mechanism 3, including a connecting rod 31 and a spiral drill bit 32. This mechanism can enter the intestine through the expander 2 to crush feces. The connecting rod 31 is connected to an external rotating mechanism via a mounting component. Driven by rotational power, the spiral drill bit 32 can penetrate deep into the hard fecal mass and crush it into smaller particles through rotational shearing, reducing defecation resistance. The crushed feces can be carried out of the body by the spiral drill bit 32 during withdrawal, reducing residue and improving defecation efficiency. In this embodiment, an angle adjustment mechanism 5 is provided between the connecting rod 31 and the cylinder 1, including a circular groove 51, a second annular plate 52, a connecting socket 53, and a flexible membrane 54, allowing the connecting rod 31 to flexibly adjust its angle within a certain range to adapt to the intestinal curvature of different patients, improving the adaptability and safety of operation.

[0050] like Figure 2 As shown, this embodiment includes a collection box 6 and a handle 7. The collection box 6 is located at the end of the cylinder 1 and communicates with the inner surface of the cylinder 1. It is used to collect crushed or ejected feces for easy cleaning. The inner surface of the cylinder 1 is provided with a brush plate 8, whose bristle structure can contact the connecting rod 31 or the auger drill bit 32. During the rotation of the crushing mechanism 3, it automatically cleans the surface residue, ensuring the crushing effect and the hygiene of the device.

[0051] This device is designed with clinical ease of use and hygiene in mind. The connecting rod 31 is detachably connected to an external rotating mechanism via a mounting component. This design allows for easy removal of the connecting rod 31 and its connected functional components from the device after each use, facilitating the replacement of new sterile components and avoiding the risk of cross-infection, thus ensuring patient safety. Furthermore, the entire device is designed for single use and meets medical-grade material standards. The materials used not only possess excellent biocompatibility, allowing contact with human tissues and fluids without adverse reactions, but also have sufficient structural strength and flexibility to ensure no damage to the intestines during insertion and operation. For example, the expander 2 and the cylinder 1, as the main structure of the device, must have a certain rigidity to maintain their shape, while also having a certain flexibility to adapt to the physiological curvature of the intestine. Materials such as polypropylene and polyethylene, which have good wear resistance and tear resistance, can be selected. The elastic sleeve 22 must have good elasticity and fit to adapt to the intestinal wall and wrap the feces. Materials such as medical-grade silicone or thermoplastic polyurethane can be selected. Here, for the other components of this device, there is no need to describe the material selection one by one. All components are based on the principle of meeting medical standards and actual operation requirements.

[0052] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
