Description

Technical Field

[0001] This invention relates to the field of medical device examination technology, specifically a waste collection device for emergency endoscopy. Background Technology

[0002] During emergency endoscopy for patients with gastrointestinal bleeding, nausea and vomiting often result in the expulsion of large amounts of blood, gastric contents, and other waste. Current clinical procedures typically use disposable drapes or basins to collect this waste. However, drapes offer poor leak-proof performance and easily contaminate the examination bed; basins require staff to hold and secure them, increasing their workload and posing a risk of spillage, which hinders infection control. Therefore, there is an urgent need for a dedicated waste collection device that can quickly secure, prevent leakage, and is suitable for endoscopic procedures.

[0003] When collecting vomit, efficient vomit recovery relies heavily on the shape stability of the vomit bag, and "full and well-formed, without wrinkles" is a key prerequisite for achieving this goal. If the vomit bag has wrinkles or collapses, it will not only obstruct the flow path of the vomit, causing some vomit to remain in the wrinkles and unable to flow smoothly into the recovery bag, but may also cause leakage due to the gaps formed by the wrinkles. At the same time, the retained vomit is difficult to clean, easily breeds bacteria, further increases the risk of infection, and makes it impossible to accurately count the amount of vomit (especially bleeding), affecting medical staff's judgment of the patient's condition. Therefore, an emergency endoscopy vomit recovery device is provided to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a waste collection device for emergency endoscopy, which achieves the effect of supporting and positioning the vomit bag to prevent wrinkles and prevents vomit from being blocked by wrinkles in the vomit bag.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0010] As a further embodiment of the present invention: a vertical guide rail is fixedly connected to the inner left side of the fixed frame, and the guide rail is slidably connected to the movable clamping block; a locking bolt is threadedly connected to the bottom of the fixed frame.

[0011] As a further embodiment of the present invention: the adjusting mechanism includes an adjusting box fixedly connected to a connecting ring. A guide rail three is fixedly connected to the right side of the adjusting box. A sliding block is slidably connected to the outer side of the guide rail three. A through groove is formed on the right side of the sliding block. A fixed rod is rotatably connected to both the front and rear sides of the through groove. The fixed rod extends outward and is fixedly connected to a crossbar on the corresponding side of the fixed frame. A pair of sliding grooves arranged horizontally are formed inside the sliding block, with the right sliding groove communicating with the through groove. Guide rail two is fixedly connected to the upper and lower sides of the two sliding grooves respectively. A slider is slidably connected to the inner side of the pair of guide rail two on the right side. A positioning block is fixedly connected to the right side of the slider, and a support spring is fixedly connected to the left side of the slider. The left side of the support spring is fixedly connected to the inner wall of the right sliding groove. A positioning ring is provided inside the through groove. A set of evenly arranged circumferential positioning grooves is formed on the outer side of the positioning ring. The positioning block is inserted into one of the positioning grooves.

[0012] As a further embodiment of the present invention: a plug is slidably connected to the inner side of a pair of guide rails on the left side, a connecting spring is fixedly connected to the right side of the plug, and the right side of the connecting spring is fixedly connected to the inner wall of the left sliding groove; a set of longitudinally evenly arranged slots are opened on the inner left wall of the adjustment box, and the plug is inserted into a slot.

[0013] As a further embodiment of the present invention: guide grooves are provided on the front sides of the interior of the two sliding grooves, and a moving block is slidably connected inside the interior of the two guide grooves.

The inner side of the stud is rotatably connected to the surface of the sliding block through a bearing. A turntable is fixedly connected to the outer side of the stud. Triangular rod one is hinged to the opposite sides of the two moving blocks through a hinge. Triangular rod two is hinged to the other end of triangular rod one through a hinge. The inner end of triangular rod two is hinged to the inner wall of the corresponding sliding groove through a hinge. The lengths of triangular rod one and triangular rod two are the same.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This emergency endoscopy waste collection device places a disposable vomit bag inside a conical cylinder. By manually stretching or gently inflating the bag, it is fully expanded to its full size, ensuring that the bottom and sidewalls of the bag fit snugly against the inner wall of the conical cylinder without any wrinkles. Then, the excess portion of the vomit bag is slipped over the outside of the collar, completely covering its outer circumference. Finally, the cover ring is aligned with the top of the collar and inserted to secure it, clamping and locking the upper edge of the vomit bag. This provides support, positioning, and wrinkle prevention for the vomit bag, preventing vomit from being blocked by wrinkles.

[0016] In addition, this emergency endoscopy waste collection device, after the vomit bag is placed and initially shaped, aligns the empty space on the right side of the fixing frame with the bed rail crossbar and inserts it into place. Then, tightening the locking bolt causes it to move upwards during rotation, pressing against the bottom of the movable clamping block and causing it to slide upwards along the guide rail until the clamping grooves of the movable and fixed clamping blocks are tightly clamped against the outside of the bed rail crossbar. This provides positioning support for the shaping mechanism and the vomit bag, ensuring no loosening or displacement during use. This further enhances the support for the vomit bag.

Detailed Implementation

[0024] like Figures 1-6 As shown, an emergency endoscopy waste collection device includes a vomit bag 10, which is conical in shape and made of medical-grade leak-proof PE+TPU composite film (thickness 0.15-0.2mm). The bottom of the vomit bag 10 has a pre-drilled opening (with an elastic sealing edge). A flexible tube 11 is connected to the bottom of the vomit bag 10 through the opening. The flexible tube 11 is made of medical-grade transparent, expandable corrugated tubing with an ultra-smooth coating on the inner wall to reduce waste residue. The bottom of the flexible tube 11 is connected to a collection bag 12 via a sealed connector. The collection bag 12 is a transparent infusion bag (capacity 500-1000ml) with precise 0-1000ml graduations printed on the side wall (thickened for every 100ml). An adjustable-length hook (with a load capacity ≥2kg) is provided at the top for easy hanging on the bed frame.

[0025] The vomit bag 10 is provided with a shaping mechanism 20 on its outer side. The shaping mechanism 20 includes a conical cylinder 201. The conical cylinder 201 is made of medical-grade transparent PVC material. Its inner side is perfectly adapted to the shape of the bottom of the vomit bag 10, which can provide external support for the vomit bag 10. The top of the conical cylinder 201 is integrally formed with a connecting ring 202 (diameter 25-30cm). The top of the connecting ring 202 is fixedly connected with a pair of front and rear mirror-symmetrical inclined rods 203 (length 10-12cm, material of medical ABS plastic). The tops of the two inclined rods 203 are fixedly connected with a collar 204 (diameter 26-31cm, with anti-slip texture on the outer side). The top of the collar 204 is inserted with a cover ring 205 (diameter 27-32cm, with a groove on the inner side that is adapted to the collar 204).

[0026] When using it, first place the disposable vomit bag 10 inside the conical cylinder 201, and stretch or blow air slightly to fully expand the vomit bag 10 to a full shape, ensuring that the bottom and side walls of the vomit bag 10 are completely attached to the inner wall of the conical cylinder 201 without any wrinkles; then, put the excess part of the vomit bag 10 on the outside of the collar 204, completely covering the outer circumference of the collar 204, and finally insert and fix the covering ring 205 with the top of the collar 204, so that the upper edge of the vomit bag 10 is clamped and locked, thereby achieving the effect of initial shaping of the vomit bag 10 and preventing it from shifting or collapsing.

[0027] Furthermore, a shaping tube 206 is provided on the inner bottom of the vomit bag 10. The shaping tube 206 is made of medical-grade transparent ABS material, is conical in shape to fit the bottom of the conical tube 201, and is hollow inside. The top boundary of the shaping tube 206 is provided with an arc-shaped transition to avoid scratching the vomit bag 10 or obstructing the flow of vomit. An insert is integrally formed at the bottom of the shaping tube 206. The insert passes through the reserved through-hole of the vomit bag 10 and through the opening at the bottom of the conical tube 201. The insert fits tightly with the elastic sealing edge of the through-hole of the vomit bag 10. The bottom of the insert is fixedly connected to the hose 11 through a sealed connector to ensure no leakage at the connection. An iron ring 208 is embedded and fixed on the outer wall of the shaping tube 206, and a ring-shaped magnet 207 is embedded and fixed at the corresponding position on the inner wall of the conical tube 201. The iron ring 208 and the magnet 207 are magnetically connected to achieve a precise fit between the shaping tube 206 and the conical tube 201.

[0028] After the vomit bag 10 is initially shaped, the shaping tube 206 is inserted into the bottom of the vomit bag 10 from the inside. The insertion tube at the bottom of the shaping tube 206 pierces through the reserved through-hole of the vomit bag 10 (the elastic sealing edge automatically tightens to fit the insertion tube) and passes through the bottom opening of the conical tube 201 until the bottom of the shaping tube 206 is in complete contact with the inner wall of the bottom of the conical tube 201. At this time, the iron ring 208 and the magnet 207 are precisely attracted, so that the vomit bag 10 located between the shaping tube 206 and the conical tube 201 is double-clamped and shaped, which can effectively prevent wrinkles from forming on the inner wall of the vomit bag 10. This design can prevent vomit from being blocked or retained by the wrinkles inside the vomit bag 10 when the patient vomits, ensuring that the vomit can be completely recovered. When a patient vomits into the vomit bag 10, the vomit slides down the smooth inner wall of the vomit bag 10, is guided into the hose 11 through the hollow channel of the shaping tube 206, and then flows into the interior of the recovery bag 12 along with the hose 11. When in use, the recovery bag 12 is suspended from the crossbar under the bed by the top hook, keeping the hose at a natural flow slope of 15-20°.

[0029] Since patients typically vomit at their bedside, the device needs to be fixed near the bed, and the vomit bag 10 needs to be tilted at a certain angle—patients are weak after surgery and find it difficult to get up and move; ideally, the patient can vomit by turning their head to the side. Therefore, this device is equipped with a clamping mechanism 30 and an adjusting mechanism 40.

[0030] refer to Figures 1-6 The clamping mechanism 30 includes a fixed frame 301, and a connecting frame 302 is fixedly connected to the left side of the fixed frame 301. The connecting frame 302 consists of a vertical rod and a horizontal rod that is perpendicularly connected to both ends of the vertical rod. The inner sides of the two horizontal rods are respectively connected to the connecting rings 202 of the shaping mechanism 20 through the adjusting mechanism 40. A fixed clamping block 304 is fixedly connected to the top of the inner side of the fixed frame 301. The bottom of the fixed clamping block 304 is provided with a triangular clamping groove. The bottom of the fixed clamping block 304 is provided with a movable clamping block 305 that can move up and down. The movable clamping block 305 is mirror-symmetrical to the fixed clamping block 304. Its top is also provided with a triangular clamping groove and an anti-slip silicone pad to adapt to the shape of the crossbar of the hospital bed guardrail.

[0031] Specifically, a vertical guide rail 303 is fixedly connected to the left side of the inside of the fixed frame 301. The guide rail 303 is slidably connected to the movable clamping block 305 to ensure that the movable clamping block 305 moves up and down smoothly. A locking bolt 306 is threadedly connected to the bottom of the fixed frame 301.

[0032] When in use, after the vomit bag 10 is placed and initially shaped, align the empty space on the right side of the fixing frame 301 with the guardrail crossbar of the hospital bed and insert it into place. Then, tighten the locking bolt 306. During the rotation, the locking bolt 306 moves upward and abuts against the bottom of the movable clamping block 305, causing the movable clamping block 305 to slide upward along the guide rail 303 until the movable clamping block 305 and the clamping groove of the fixed clamping block 304 are tightly clamped on the outside of the guardrail crossbar, thereby achieving positioning support for the shaping mechanism 20 and the vomit bag 10, ensuring that there is no loosening or displacement during use.

[0033] refer to Figure 4 The adjusting mechanism 40 includes an adjusting box 401 fixedly connected to the connecting ring 202. A guide rail three (vertical direction) is fixedly connected to the right side of the adjusting box 401. A sliding block 402 is slidably connected to the outer side of the guide rail three. A through groove 403 is formed on the right side of the sliding block 402. A fixed rod 404 is rotatably connected to both the front and rear sides of the through groove 403. The fixed rod 404 extends outward and is fixedly connected to the corresponding horizontal bar in the fixed frame 301. A pair of sliding grooves 405 arranged horizontally are formed inside the sliding block 402, wherein the right sliding groove 405 is connected to the through groove 402. 3. The two sliding grooves 405 are connected to the upper and lower sides of the inner sides of the two sliding grooves 405 respectively. The inner sides of the two guide rails 406 on the right side are slidably connected to the slider 407. The right side of the slider 407 is fixedly connected to the positioning block 408, and the left side of the slider 407 is fixedly connected to the support spring 409. The left side of the support spring 409 is fixedly connected to the inner wall of the right sliding groove 405. The through groove 403 is provided with a positioning ring 410 inside. The outer side of the positioning ring 410 is provided with a set of circumferentially evenly arranged positioning grooves 411. The positioning block 408 is inserted into and engaged with a certain positioning groove 411.

[0034] Furthermore, a plug 412 is slidably connected to the inner side of a pair of guide rails 406 on the left side. A connecting spring 413 is fixedly connected to the right side of the plug 412. The right side of the connecting spring 413 is fixedly connected to the inner wall of the left sliding groove 405. A set of longitudinally evenly arranged slots 414 are opened on the inner left wall of the adjustment box 401. The plug 412 is inserted into a slot 414.

[0035] In the unlocked state, only the arc portion of the insert block 412 is inserted into the slot 414, and only the semicircular portion of the positioning block 408 is inserted into the positioning groove 411. At this time, the position and angle of the sliding block 402 cannot be completely fixed. In this state, rotating the conical cylinder 201 clockwise will cause the vomit bag 10 to rotate as well: during rotation, the adjusting box 401 causes the sliding block 402 to rotate around the fixing rod 404. The rotation force causes the semicircular portion of the positioning block 408 to contact the boundary of the positioning groove 411. The contact force pushes the positioning block 408 to move to the left and disengage from the positioning groove 411, while simultaneously compressing the support spring 409. When rotated to the appropriate angle, the support spring 409 rebounds, causing the positioning block 408 to engage with the corresponding positioning groove 411, completing the angle adjustment. This design allows the opening of the vomit bag 10 to face the patient—the vertical vomit bag 10 requires the patient to stand up and bend over to vomit, while the tilted vomit bag 10 allows the patient to vomit simply by turning their head to the side, significantly reducing the patient's physical exertion and adapting to the weakened state after surgery.

[0036] Similarly, in the unlocked state, when the conical cylinder 201 is pulled up or down, since the conical cylinder 201 is fixedly connected to the adjustment box 401, the pulling force acts on the insert 412, causing the arc-shaped end of the insert 412 to contact the boundary of the slot 414. The contact force pushes the insert 412 inward and compresses the connecting spring 413. When it slides to the next slot 414, the connecting spring 413 rebounds, pushing the insert 412 into the slot 414. For continued adjustment, only a continuous force needs to be applied, and the insert 412 will sequentially insert into and disengage from each slot 414 along the path. The resulting click helps the operator determine whether the insert 412 is accurately inserted. During this adjustment process, the relative position of the sliding block 402 and the fixed rod 404 remains unchanged, and the heights of the adjustment box 401, the shaping mechanism 20, and the vomit bag 10 change synchronously, allowing for precise adjustment of the distance between the opening of the vomit bag 10 and the patient's head, providing the patient with a more comfortable vomiting posture.

[0037] Furthermore, guide grooves 415 (horizontal direction) are provided on the front side of the interior of the two sliding grooves 405. The interior of the two guide grooves 415 is slidably connected to a moving block 416. The exterior of the two moving blocks 416 is fixedly connected to a horizontal plate. The interior of the horizontal plate is threadedly connected to a stud 417. The interior of the stud 417 is rotatably connected to the surface of the sliding block 402 through a bearing. The exterior of the stud 417 is fixedly connected to a turntable. The opposite sides of the two moving blocks 416 are hinged to a triangular rod 418 through a hinge. The other end of the triangular rod 418 is hinged to a triangular rod 419 through a hinge. The interior end of the triangular rod 419 is hinged to the inner wall of the corresponding sliding groove 405 through a hinge. The lengths of the triangular rod 418 and the triangular rod 419 are the same, forming a symmetrical triangular support structure.

[0038] After adjusting the tilt angle and height of the vomit bag 10, it needs to be locked and positioned: Rotating the turntable causes the stud 417 to rotate. Since the stud 417 is threadedly connected to the horizontal plate, during rotation, it pushes the horizontal plate and the moving block 416 inward along the guide groove 415. As the moving block 416 moves, it causes the hinged end of the first triangular rod 418 to move inward, gradually reducing the angle between the first triangular rod 418 and the second triangular rod 419, while simultaneously increasing the horizontal length of the triangle formed by them. During this process, the outer ends of the two triangular rods 418 and 419 respectively abut against the inner sides of the insert block 412 and the slider 407, and apply an outward pushing force, causing the insert block 412 and the slider 407 to move outward along the corresponding guide rail 406. Finally, the insert block 412 is firmly inserted into the corresponding slot 414, and the positioning block 408 is firmly inserted into the corresponding positioning groove 411, so as to achieve stable positioning of the vomit bag 10 after adjustment, and avoid angle and height deviation caused by changes in body position or impact of vomit during use.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
