Description

Technical Field

[0001] The present application relates to the technical field of medical tools, and more specifically, to a stool collector. Background Art

[0002] During the process of intensive care, it is often necessary to collect the patient's feces. Clinically, a stoma bag is used to collect feces by sticking it to the anus, but the disadvantage is that the stoma bag is easy to fall off. Another method is drainage tube drainage, which drains the feces into a drainage bag outside the body through a drainage tube.

[0003] During the drainage process, a drainage tube is inserted into the patient's anus. Not only is it unstable, but feces can easily overflow from the anus along the wall of the drainage tube, causing redness, edema or ulceration of the skin around the anus. The patient is not comfortable, and the tube can also stain clothes and bed sheets, making care difficult.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0005] The purpose of the present application is to provide a stool collector, which solves the problem that the drainage tube used in the prior art collects stool, causing the stool to easily overflow from the anus along the drainage tube wall, making medical care difficult.

[0018] Optionally, the driving part includes: a driving airbag connected to the proximal end of the drainage tube, and the driving airbag expands by being inflated to squeeze the elastic part, so that the supporting part moves away from the central axis of the drainage tube.

[0019] Optionally, a ventilation pipe is provided in the drainage tube, and the ventilation pipe is connected to the limiting airbag and the driving airbag.

[0020] Optionally, the driving unit includes: a pulling assembly connected to the distal end of the drainage tube;

[0021] A plurality of pull ropes, one end of each of which is connected to the pulling assembly, and the other end of each of which is connected to a plurality of support bars;

[0022] The support part applies force to the elastic part by pulling the pull rope, so that the elastic part moves closer to or away from the central axis of the drainage tube.

[0023] Optionally, the pulling assembly comprises:

[0024] A pull ring, which is sleeved on the drainage tube;

[0025] A screw pipe, which is screwed onto the drainage tube, and one end of which is movably connected to the pull ring;

[0047] like Figure 1 As shown, this embodiment provides a stool collector, which is used to be inserted into the anus of a patient to discharge stool in the patient's rectum. For the convenience of structural description, the end inserted into the patient's body is the proximal end, which is also the front end, and the end opposite to the proximal end is the distal end, i.e., the rear end. The structural description of each component of this embodiment is based on this direction.

[0048] like Figure 1, Figure 2 As shown, the stool collector of this embodiment mainly includes: a drainage tube 100, a limiting airbag 200, an elastic bracket 300, a driving unit 400 and an elastic enclosure 500. The proximal end of the drainage tube 100 is used to be inserted into the anus of the patient, and the limiting airbag 200 is arranged on the outer wall of the drainage tube 100 near the proximal end. The limiting airbag 200 expands after the drainage tube 100 is inserted into the anus, so that the drainage tube 100 can be stuck in the anus of the patient for fixation. The elastic support 300 is arranged at the proximal end of the drainage tube 100, and the driving unit 400 is arranged on the drainage tube 100. The elastic support 300 is driven by the driving unit 400 to collapse toward the central axis of the drainage tube 100 or expand away from the central axis of the drainage tube 100; the elastic enclosure 500 is connected to the elastic support 300 and connected to the drainage tube 100, and the elastic enclosure 500 encloses a collection space; the elastic enclosure 500 shrinks by the collapse of the elastic support 300, or the elastic enclosure 500 opens the collection space by the expansion of the elastic support 300. A flushing pipe 110 is also arranged on the wall of the drainage tube 100, and a flushing port is opened at the proximal end of the drainage tube 100. The flushing pipe 110 is connected to the flushing port and can be flushed with external flushing water.

[0049] like Figure 1 , Figure 2 As shown, a stool collector of this embodiment is provided, by inserting the front end of the drainage tube 100 into the anus of the patient, and inserting the elastic support 300 into the rectum. The limiting airbag 200 is inflated and pressed against the anus, so that the drainage tube 100 can be fixed in the anus; under the action of the driving unit 400, the elastic support 300 is driven away from the central axis of the drainage tube 100, so as to be unfolded, and the elastic enclosure 500 outside the elastic support 300 is unfolded as the elastic support 300 is opened, and a trumpet-shaped collection space is formed therein, and the edge of the elastic enclosure 500 can be pressed against the inner wall of the patient's rectum under the elastic force of the elastic support 300, so that the excrement in the rectum is directly diverted into the drainage tube 100 through the trumpet-shaped collection space, so as to be collected at the far end of the drainage tube 100. In this way, the problem of stool overflowing from the anus along the wall of the drainage tube 100 is avoided, making the medical care process more convenient. When defecation is completed, the elastic support 300 is retracted toward the central axis of the drainage tube 100, so that the elastic cover 500 is contracted by the retraction of the elastic support 300, so that the volume of the elastic cover 500 becomes smaller after contraction, thereby facilitating its removal from the anus.

[0050] like Figure 1 , Figure 2 , Figure 3As shown, further, the elastic support 300 of this embodiment specifically includes: a plurality of support bars 310, one end of each of the plurality of support bars 310 is connected to the drainage tube 100, and the plurality of support bars 310 are arranged at intervals around the central axis of the drainage tube 100. The drainage tube 100 adopts a round tube, and the middle of the drainage tube 100 is a drainage channel, and the drainage channel is surrounded by a plurality of support bars 310, and the lower end of each support bar 310 is connected to the top and upper end of the drainage tube 100 and is movably arranged. By moving the upper end of each support bar 310 toward the central axis of the drainage tube 100 (moving inward), the elastic support 300 is folded, and the elastic enclosure 500 is folded. By moving the upper end of each support bar 310 away from the central axis of the drainage tube 100 (moving outward), the elastic support 300 is unfolded, and the elastic enclosure 500 is unfolded.

[0051] like Figure 1 , Figure 2 , Figure 3 As shown, further, each support bar 310 of this embodiment includes: an elastic part 320 and a support part 330. The elastic part 320 is arranged on the proximal end of the drainage tube 100, the support part 330 is connected to the elastic part 320, and the elastic cover 500 is connected to the support part 330. The support part 330 is close to or away from the central axis of the drainage tube 100 through the elastic action of the elastic part 320. In the specific structure, the elastic part 320 generates an elastic force, which cooperates with the driving part 400 to control the movement of the support part 330; when the driving part 400 pushes the upper part of the support part 330 away from the central axis, the elastic part 320 generates an elastic force that makes the upper part of the support part 330 close to the central axis. Alternatively, when the elastic force of the elastic part 320 pushes the upper part of the support part 330 away from the central axis, the driving part 400 can pull the support part 330 to make the upper part of the support part 330 close to the central axis.

[0052] According to different driving modes, the specific structure of the corresponding driving unit 400 can adopt various forms, as follows:

[0053] like Figure 2 , Figure 3As shown, in the first structural form of the driving part 400, the driving part 400 specifically includes: a driving airbag 410, the driving airbag 410 is connected to the proximal end of the drainage tube 100, and the driving airbag 410 is expanded by inflation to squeeze the elastic part 320, so that the support part 330 moves away from the central axis of the drainage tube 100. The driving airbag 410 is driven, and after the driving airbag 410 is inflated, the elastic part 320 can be squeezed, so that the elastic part 320 is deformed outward, and then the support part 330 on it is tilted outward, so that the upper end of the support part 330 is outward away from the central axis, so that the elastic enclosure 500 is opened. When the driving airbag 410 is deflated and contracted, the elastic part 320 returns the support part 330 under the action of its own elastic force, so that the upper end of the support part 330 moves inward, and then the elastic enclosure 500 is contracted.

[0054] like Figure 2 , Figure 3 As shown, in this embodiment, the elastic part 320 specifically includes: a connecting plate 321 and a bending plate 322, the connecting plate 321 is fixedly connected to the drainage tube 100, the bending plate 322 is connected to the rear end of the connecting plate 321, and is located on the outside of the connecting plate 321 after bending forward, so that a U-shaped groove 323 is formed between the bending plate 322 and the connecting plate 321, and the opening of the U-shaped groove 323 faces forward. The bending plate 322 protrudes forward from the upper surface of the drainage tube, the support part 330 is fixedly connected to the front end of the bending plate 322, and the driving airbag 410 is fixed on the upper surface of the drainage tube. When the driving airbag 410 expands, it squeezes the bending plate 322 located on the outside, so that the upper end of the bending plate 322 is outwardly away from the central axis, and the bending plate 322 is deformed and tilted, thereby driving the upper end of the support part 330 to move outward. Since the U-shaped groove 323 opens upward, when the bending plate 322 is squeezed, the upper part is easily deformed, driving the elastic enclosure 500 to achieve an expansion effect. After the driving airbag 410 is deflated, the elastic structure of the U-shaped groove 323 is more likely to return to its original position, thereby driving the elastic enclosure 500 to achieve contraction. The elastic enclosure 500 is folded and contracted, for example, like an umbrella.

[0055] like Figure 2 , Figure 3As shown, further, the elastic part 320 also includes: a limiting plate 324, the limiting plate 324 is connected to the bending plate 322 and is located above the connecting plate 321, and there is a gap between the limiting plate 324 and the top of the drainage tube 100, so that the driving airbag 410 is located in the gap. In this way, the driving airbag 410 is located below the limiting plate 324. When the driving airbag 410 is inflated, due to the obstruction of the limiting plate 324 above, the deformation tendency of the driving airbag 410 is concentrated on the bending plate 322, so that the extrusion force of the driving airbag 410 toward the outside increases and the bending plate 322 is pushed toward the outside, so that the bending plate 322 is more easily deformed, which is convenient for pushing the bending plate 322.

[0056] like Figure 2 , Figure 3 As shown, further, the lower part of the driving airbag 410 in this embodiment is partially connected to the top of the drainage tube 100, and the other part extends into the U-shaped groove 323. For example, it can be bonded and fixed to the inner wall of the connecting plate 321. When the driving airbag 410 is inflated, the part located in the U-shaped groove 323 can also squeeze and apply force to the bending plate 322 in the U-shaped groove 323, so that the bending plate 322 is more easily deformed. In addition, by the driving airbag 410 to expand and fill the U-shaped groove 323, it is also difficult for excrement to enter the U-shaped groove 323, avoiding the problem of inconvenience in subsequent cleaning.

[0057] like Figure 2 , Figure 3 As shown, further, a mounting groove 120 is provided on the outer wall of the front end of the drainage tube 100 of this embodiment, the front opening of the mounting groove 120 is located at the front end of the drainage tube 100, and the notch of the mounting groove 120 is located on the outer wall of the drainage tube 100. The elastic part 320 is fixedly arranged in the mounting groove 120, and after the driving airbag 410 is deflated and contracted, the connecting plate 321 can return to its original position and be accommodated in the mounting groove 120, so that the contracted elastic bracket 300 and the elastic enclosure 500 are as close to the central axis as possible, and the outer diameter after contraction becomes smaller, which is conducive to inserting the drainage tube 100 in the contracted state into the patient's anus.

[0058] like Figure 2 , Figure 3 As shown, further, a ventilation pipe 130 is provided in the drainage tube 100 of this embodiment, and the ventilation pipe 130 is connected to the limiting airbag 200 and the driving airbag 410. A trachea joint is connected to the distal end of the ventilation pipe 130, and after the trachea joint is connected with a syringe, the limiting airbag 200 and the driving airbag 410 can be inflated at the same time by the syringe, which has a simple structure, is easy to process and produce, and is more convenient to use, and is convenient for medical staff to use.

[0059] like Figure 1 , Figure 4 , Figure 5 As shown, in the second structural form of the driving part 400, the driving part 400 specifically includes: a pulling assembly 420 and a plurality of pull ropes 430. The pulling assembly 420 is connected to the distal end of the drainage tube 100, and one end of the plurality of pull ropes 430 is connected to the pulling assembly 420, and the other end is respectively connected to a plurality of support bars 310; the support part 330 applies force to the elastic part 320 by pulling the pull rope 430, so as to approach or move away from the central axis of the drainage tube 100 under the elastic action of the elastic part 320. In the specific structure, the elastic part 320 may also include: a connecting plate 321 and a bending plate 322. The connecting plate 321 is fixedly connected to the drainage tube 100, and the bending plate 322 is connected to the rear end of the connecting plate 321, and is located on the outside of the connecting plate 321 after bending forward, so that a U-shaped groove 323 is formed between the bending plate 322 and the connecting plate 321, and the opening of the U-shaped groove 323 faces forward. The difference from the above structure is that the initial state of the elastic part 320 (the state in which no deformation is generated and elastic force is generated) is a state in which the upper end of the support part 330 is away from the central axis. Therefore, when the elastic enclosure 500 is in a contracted state, the pulling assembly 420 tightens the support bar 310 through a plurality of pull ropes 430; when the pulling assembly 420 moves toward the front (proximal end) along the drainage tube 100, the pull ropes 430 are loosened, so that the elastic part 320 in the contracted state, under the action of its own elastic force, causes the bending plate 322 to spring open, and the upper end of the bending plate 322 moves outward away from the central axis, and the bending plate 322 deforms and tilts, thereby driving the upper end of the support part 330 to move outward, driving the elastic enclosure 500 to achieve the unfolding effect. When the pulling assembly 420 moves toward the rear (distal end) along the drainage tube 100, the pull rope 430 is tightened, so that the elastic part 320 in the open state is deformed under the pulling force of the pull rope 430 to generate elastic force, and the bending plate 322 returns to the inside, thereby driving the upper end of the support part 330 to move inward, driving the elastic cover 500 to achieve a contraction effect.

[0060] like Figure 4 , Figure 6 , Figure 7 As shown, further, the pulling assembly 420 of this embodiment specifically includes: a pull ring 421 and a screw pipe 425. The pull ring 421 is sleeved on the drainage tube 100, the screw pipe 425 is screwed on the drainage tube 100, and one end of the screw pipe 425 is movably connected to the pull ring 421; the pull ring 421 is driven to move along the axial direction of the drainage tube 100 by screwing the screw pipe 425. The screw pipe 425 can move forward and backward along the axial direction of the drainage tube 100 by screwing, thereby driving the pull ring 421 to move forward and backward, and the pull ring 421 then pulls the pull rope 430 to achieve control of the pull rope 430.

[0061] like Figure 4 , Figure 6 , Figure 7As shown, specifically, a threading hole 140 is provided on the drainage tube 100, and the pull rope 430 is inserted into the threading hole 140. A guide groove 150 is provided on the outer wall of the drainage tube 100, and a plurality of guide grooves 150 are provided, and the plurality of guide grooves 150 correspond to the threading hole 140, so that the threading hole 140 penetrates the front inner wall of the guide groove 150. The guide groove 150 is extended in the front-back direction, and its length is the same as the moving length of the pull rope 430. The pull ring 421 includes a ring body 422 and a plurality of inner protrusions 423, and the plurality of inner protrusions 423 are opposite to the guide groove 150 one by one and are slidably arranged in the guide groove 150. The ring body 422 is sleeved on the outer side of the drainage tube 100. Since the outer side of the drainage tube 100 needs to be provided with an external thread 160, the inner wall of the ring body 422 is on the outer side of the external thread 160. A T-shaped ring groove 424 is provided at the distal end of the ring body 422, and a T-shaped ring head 426 is provided at the proximal end of the screw tube 425. The T-shaped ring head 426 is sleeved outside the drainage tube 100 and movably embedded in the T-shaped ring groove 424. An internal thread 427 is provided on the inner wall of the screw tube 425. The internal thread 427 of the screw tube 425 cooperates with the external thread 160 on the drainage tube 100, so that the screw tube 425 can be screwed to move forward or backward along the drainage tube 100. Since the T-shaped ring head 426 can rotate in the T-shaped ring groove 424, the forward and backward movement of the screw tube 425 can drive the ring body 422 to move forward and backward along the drainage tube 100.

[0062] like Figure 5 As shown, further, in order to prevent excrement from leaking out of the threading hole 140, a sealing ring 141 is provided on the inner wall of the front end of the threading hole 140, and the pull rope 430 is passed through the sealing ring 141. The opening of the threading hole 140 is blocked by the sealing ring 141, so that the threading rope can be pulled without leakage of the threading hole 140.

[0063] like Figure 4 , Figure 8As shown, further, since the elastic member 333 is relatively small in a small space, when the deformation amplitude of the elastic member 333 is relatively small, for a rectum with a relatively large diameter, the opening inner diameter of the elastic enclosure 500 needs to be increased so that it can be against the rectum. Therefore, it is necessary to increase the length of the support portion 330. Under a limited tilt deformation angle, the longer the support portion 330 is, the larger the opening diameter of the elastic enclosure 500 is. In addition, the problem of convenient insertion into the patient's anus and being able to adapt to the patient's rectal contour is considered. The support portion 330 is set to a retractable shape, which can specifically include: a main support rod 331 and a movable support rod 334. The main support rod 331 is connected to the elastic portion 320, the movable support rod 334 is telescopically arranged on the main support rod 331, and the pull rope 430 is connected to the movable support rod 334. Through the movable arrangement of the movable support rod 334 and the main support rod 331, when the pull rope 430 is released, the movable support rod 334 and the main support rod 331 are tilted outward under the action of the elastic part 320, and then the movable support rod 334 is extended from the main support rod 331. The tilted extension of the movable support rod 334 causes the elastic enclosure 500 to expand outward, and the opening inner diameter of the elastic enclosure 500 becomes larger and abuts against the inner wall of the rectum. The front end of the elastic enclosure 500 is fixed to the front end of the movable support rod 334, and the elastic enclosure 500 can be folded to a certain extent in the front-to-back direction to facilitate its extension.

[0064] like Figure 8 As shown, further, in this embodiment, a receiving chamber 332 is provided in the main support rod 331, and a movable support rod 334 is telescopically provided in the receiving chamber 332; an elastic member 333 is provided in the receiving chamber 332, and the elastic member 333 is connected to the movable support rod 334, and pushes the movable support rod 334 out of the receiving chamber 332 through elastic force. The movable support rod 334 can enter and exit the receiving chamber 332 through the action of the elastic member 333, thereby realizing the telescopic function.

[0065] like Figure 8As shown, the elastic member 333 in this embodiment can be a spring, and the elastic coefficient of the elastic member 333 is smaller than that of the elastic part 320. That is, in the process of being subjected to force, the elastic member 333 is more easily deformed while the elastic part 320 is not easily deformed. Therefore, when the elastic support 300 is in the process of being unfolded, it is necessary to screw the screw tube 425 to move forward, so as to release the drawstring 430 through the pull ring 421 that moves forward. Since the elastic part 320 is more difficult to deform, the elastic potential energy generated after its compression is relatively large, so it will first respond to the space released by releasing the drawstring 430, so as to first deform toward the outside, so that the movable support rod 334 and the main support rod 331 are tilted outward under the action of the elastic part 320. When the entire elastic part 320 is fully unfolded, the drawstring 430 is continuously released. At this time, the movable support rod 334 is extended outward under the action of the elastic member 333, and the front end is pressed against the inner wall of the rectum. Thereby, the elastic bracket 300 can ensure that the supporting part 330 is tilted as a whole first and then the movable support rod 334 is extended during the unfolding process. Such a gradual unfolding process can make the elastic cover 500 fully unfolded and stably rest against the inner wall of the patient's rectum, and it is not easy to cause the problem of insufficient expansion.

[0066] During the folding process of the elastic support 300, the screw tube 425 needs to be screwed to move backward, so that the pull rope 430 is pulled backward through the pull ring 421 that moves backward. Since the elastic member 333 is more easily deformed and the pull rope 430 is pulled on the movable support rod 334, the movable support rod 334 will first respond to the force applied by tightening the pull rope 430, and thus first shrink into the main support rod 331. When the movable support rod 334 receives the limit position of the main support rod 331, the pull rope 430 is continuously tightened, and at this time, the elastic part 320 begins to respond to the pulling force of the pull rope 430, so that the movable support rod 334 and the main support rod 331 shrink inward together under the action of the elastic part 320. Therefore, during the folding process of the elastic support 300, the movable support rod 334 is first folded, and then the support part 330 is folded as a whole. Such a gradual folding process can make the folding process more stable.

[0067] like Figure 1 , Figure 4 As shown, on the basis of the above structure, the front end of the elastic enclosure 500 of this embodiment is provided with a flexible protective layer 510, and the flexible protective layer 510 covers the proximal end of the elastic support 300. The flexible protective layer 510 has a certain elasticity, and it covers the front end of the elastic support 300 to prevent the elastic support 300 from damaging the rectum during the deployment process.

[0068] In summary, the stool collector provided by the present application can expand or contract the elastic cover by driving the elastic bracket. After the elastic cover is inserted into the anus, it is expanded in the rectum, and a trumpet-shaped collection space is formed therein. The edge of the elastic cover can be pressed against the inner wall of the patient's rectum under the elastic force of the elastic bracket, so that the excrement in the rectum is directly guided into the drainage tube through the trumpet-shaped collection space, and then collected at the far end of the drainage tube. In this way, the problem of stool overflowing from the anus along the drainage tube wall is avoided, making the medical care process more convenient.

[0069] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
