Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a patient vomit collection device. Background Technology
[0002] In patient care, vomiting management is a common aspect. Patients typically use vomit bags, where they vomit directly into the bag and then dispose of it in a recycling bin. However, the amount of vomit escaping per episode varies depending on the patient's condition. Vomit bags are relatively soft, requiring the opening to be stretched, making them inconvenient to use and prone to tearing. Furthermore, for patients with frequent, intermittent vomiting and small amounts vomited at a time, requiring a separate vomit bag for each episode is also very wasteful of supplies.
[0003] Therefore, some cup-shaped (or bottle-shaped) vomiting devices, or simply vomit cups, are available on the market. Vomit is poured in through the rim of the cup, making them suitable for frequent vomiting. However, using a vomit cup can result in odor leakage. A baffle can be added to the rim of the cup, which is opened before use and closed afterward. However, this type of device is still somewhat inconvenient to operate. Therefore, there is an urgent need to design a device that can solve both the odor leakage problem of vomit cups and overcome the inconvenience caused by the baffle, thereby improving the patient's nursing experience. Summary of the Invention
[0004] The purpose of this invention is to provide a patient vomit collection device that solves the problems of odor leakage from the vomit cup and inconvenient operation in patient care.
[0005] To achieve this objective, the technical solution of this utility model is as follows: a patient vomit collection device, comprising a cup lid assembly, an elastic telescopic tube, and a cup body, wherein the cup lid assembly is vertically elastically connected to the cup body through the elastic telescopic tube;
[0006] The cup lid assembly includes a cup lid and a vomiting tube located at the center of the cup lid and extending downwards. The lower end of the vomiting tube has circumferentially spaced drain ports and a baffle at the bottom to close the ports.
[0007] The top of the cup body is provided with an annular partition along the inner wall. The outer edge of the partition is connected to the inner wall of the cup body. The vomiting catheter is vertically movably inserted through the annular inner hole of the partition, and the vomiting catheter is provided with a limiting member below the partition to limit the vertical movement of the partition.
[0008] Furthermore, the limiting member is an annular limiting edge formed by the outward extension of the baffle, and the limiting edge contacts the bottom surface of the partition for vertical limiting.
[0009] Furthermore, the inner edge of the partition extends upward to form a guide sleeve, and the vomiting catheter is vertically movably inserted through the guide sleeve.
[0010] Furthermore, a spring is provided between the guide sleeve and the cup lid to provide vertical restoring force after the elastic telescopic tube is compressed.
[0011] Furthermore, the spring is sleeved on the outer wall of the vomiting tube and its upper and lower ends are respectively connected to the cup lid and the guide sleeve.
[0012] Furthermore, the spring is sleeved on the outer wall of the guide sleeve and its upper and lower ends are respectively connected to the cup lid and the partition.
[0013] Furthermore, the baffle has an upward protrusion at its center, forming a guide cone.
[0014] Furthermore, the lower end of the drain outlet is connected to the top surface of the baffle.
[0015] Furthermore, a handle is provided on the outer wall of the cup.
[0016] Furthermore, the upper end of the vomiting catheter protrudes from the cup lid and is connected to the cup lid via an arc transition.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. Due to the elasticity of the flexible telescopic tube, it is compressed when the cup lid is pressed down and automatically resets when the lid is released. When using this product, the patient holds the cup, aligns their mouth with the opening of the vomiting catheter, and moves their face downwards or upwards, causing the flexible telescopic tube to compress. This moves the vomiting catheter's discharge port below the partition. After normal vomiting, the vomit flows from the discharge port into the cup. After vomiting, the product can be removed, and the vomiting catheter resets. The baffle at its bottom blocks the round hole and is secured to the bottom of the partition by a limiting component. This not only prevents odor leakage but also prevents the vomiting catheter from detaching from the partition due to excessive rebound force. This invention is very simple to use, requiring no opening or closing operations. The flexible telescopic tube automatically blocks the round hole, effectively preventing the odor of vomit from escaping.
[0019] 2. This device is designed with a limiting edge that is locked on the bottom surface of the annular inner hole of the partition for vertical limiting. This can further ensure the sealing of the device and also prevent the compressed elastic telescopic tube from automatically rebounding after the patient uses it. Excessive rebound impact force could cause the lower end of the vomiting catheter to detach from the partition, which could easily damage the device and reduce its service life.
[0020] 3. This device has a guide sleeve that matches the outer diameter of the vomiting tube. This ensures that the vomiting tube moves stably during the pressing and restoring of the cup lid, avoiding damage to the device due to excessive pressing force and excessive rebound force, increasing the service life of the device, and further enhancing the sealing of the device to prevent odor leakage.
[0021] 4. A spring is installed between the guide sleeve and the cup lid to further enhance the restoring force after the device is used, assist the elastic telescopic tube to rebound, and enable the device to quickly reset and seal, preventing odor leakage.
[0022] 5. When pressing down the cup lid, the guide sleeve, with the help of the vertical support force of the partition, compresses the spring. After using the device, the compressed spring provides a vertical restoring force to help the device quickly return to its original position.
[0023] 6. When pressing down the cup lid, since the lower end of the spring is connected to the partition, the spring can be compressed with the help of the vertical support force of the partition. After use, the spring rebounds and the device can be quickly reset.
[0024] 7. A guide cone is installed. The structure of the guide cone allows liquid vomit to flow from a high point to a low point at the drain outlet, ensuring that the liquid vomit enters and leaves the drain outlet smoothly and avoiding blockage of the vomiting tube due to incomplete downward pressure.
[0025] 8. Connect the bottom of the drain outlet to the top of the baffle so that the top of the baffle is not lower than the bottom of the drain outlet. This ensures that vomit is discharged from the drain outlet as much as possible, avoiding residue left on the baffle, which would cause odor leakage from the device and make subsequent cleaning of the device inconvenient.
[0026] 9. A handle is provided for comfortable gripping by the user, preventing the device from falling off and being damaged;
[0027] 10. The design of the vomiting catheter protruding from the cup lid is ergonomic. It not only makes it easier for the patient to align the catheter, but also reduces facial pressure points, increases user comfort, avoids injury to the patient's face, and facilitates cleaning of the device, extending its service life. It is safe and hygienic. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0036] This utility model relates to a patient vomit collection device for convenient, quick, safe, and hygienic collection of patient vomit. Conventional vomit collection devices suffer from problems such as odor leakage from the vomit cup and inconvenient operation during patient care. When using this device, the patient holds the cup, aligns their mouth with the opening of the vomiting catheter 5, and moves their face downwards or upwards, compressing the elastic telescopic tube 3. The drain port 6 of the vomiting catheter 5 moves below the partition 4. After the patient vomits normally, the vomit flows from the drain port 6 into the cup 2. After vomiting, the device is removed, and the vomiting catheter 5 returns to its original position. The baffle 7 at its bottom blocks the round hole and is secured to the bottom of the partition 4 by a limiting member. This not only prevents odor leakage but also prevents the vomiting catheter 5 from detaching from the partition 4 due to excessive rebound force. This solves the problems of odor leakage from the vomit cup and inconvenient operation when patients use vomit collection devices, making operation simple and quick.
[0037] A patient vomit collection device, specifically, such as Figure 1-3 As shown, it includes a cup lid assembly, an elastic telescopic tube 3, and a cup body 2. The cup lid assembly is vertically elastically connected to the cup body 2 through the elastic telescopic tube 3.
[0038] The cup lid assembly includes a cup lid 1 and a vomiting tube 5 located at the center of the cup lid 1 and extending downward. The lower end of the vomiting tube 5 has circumferentially spaced drain ports 6 and a baffle 7 at the bottom to close the ports.
[0039] A ring-shaped partition 4 is provided around the inner wall of the cup body 2. The outer edge of the partition 4 is connected to the inner wall of the cup body 2. The vomiting tube 5 is vertically movably inserted through the ring-shaped inner hole of the partition 4, and the vomiting tube 5 is provided with a limiting member below the partition 4 to limit the vertical movement of the partition 4.
[0040] The cup lid 1 and the vomiting catheter 5 are integrated. Multiple drainage ports are spaced circumferentially along the lower end of the vomiting catheter 5. Figure 2 There are 6 drain outlets shown. The flexible expansion fitting 3 includes a flexible expansion corrugated sleeve. The expansion corrugated sleeve has good flexibility and elasticity, and can also maintain a good sealing effect to prevent odor leakage.
[0041] When not in use, the drain port 6 is located above the partition 4, the elastic telescopic tube 3 is extended, and the baffle 7 at the bottom of the vomiting catheter 5 can block the annular inner hole of the partition 4. The limiting component is stuck on the bottom surface of the annular inner hole of the partition 4 to provide vertical limitation. When in use, the cup lid 1 is pressed down directly or indirectly, causing the elastic telescopic tube 3 to be compressed, so that the drain port 6 of the vomiting catheter 5 can move below the partition 4. After the patient vomits normally, the vomit flows from the drain port 6 into the cup body 2. After vomiting, the product can be removed. The compressed elastic telescopic component 3 rebounds and unfolds again, and the vomiting catheter 5 returns to its original position. The baffle 7 at its bottom blocks the annular inner hole of the partition 4, which can effectively prevent odor from overflowing. The limiting component is stuck at the bottom of the partition 4 to prevent the vomiting catheter 5 from detaching from the partition 4 due to excessive rebound force, which would cause damage to the device.
[0042] In one embodiment, the bottom of the cup body 2 may be provided with a movable opening or a detachable cup bottom or a threaded cup bottom. By opening the movable opening or the cup bottom, vomit can be poured out, avoiding pouring out from the vomiting catheter 5 opening, which would contaminate the vomiting catheter 5 opening and cause secondary infection after patient contact. It is also convenient to clean. When cleaning, the cup lid can be pressed to pour clean water into the vomiting catheter 5 opening. Clean water enters the cup body from the drain port 6 to clean the inner wall. The movable opening at the bottom of the cup body 2 or the detachable cup bottom or threaded cup bottom can be opened to drain the sewage. This reduces the chance of direct contact between the hands and vomit, reduces the risk of infection, makes the cleaning process more convenient and faster, and improves the safety of operation.
[0043] In one embodiment, such as Figure 2-3As shown, the limiting component is an annular limiting edge 72 formed by the outward extension of the baffle 7. The limiting edge 72 contacts the bottom surface of the partition 4 for vertical limiting. When the device is not in use, the limiting edge 72 is engaged with the bottom surface of the annular inner hole of the partition 4 to play a vertical limiting role, preventing the lower end of the vomiting tube 5 from detaching from the partition 4 due to excessive elastic rebound force of the elastic telescopic tube 3, which could lead to odor leakage and damage to the device.
[0044] In one embodiment, such as Figure 2 As shown, the inner edge of the partition 4 extends upward to form a guide sleeve 41, and the vomiting tube 5 is vertically and movably inserted through the guide sleeve 41. The inner diameter of the guide sleeve 41 matches the outer diameter of the vomiting tube 5, ensuring stable movement of the vomiting tube 5 during the pressing and restoring of the cup lid 1. This provides good guidance and prevents instability of the vomiting tube 5 during the pressing and restoring of the lid 1, which could lead to device damage and reduce the device's service life. In addition, it also strengthens the device's sealing measures to prevent odor leakage.
[0045] In one embodiment, such as Figure 2 As shown, a spring 8 is also provided between the guide sleeve 41 and the cup lid 1 to provide vertical restoring force after the elastic telescopic tube 3 is compressed. Under normal circumstances, the elastic telescopic corrugated sleeve has sufficient restoring force to reset the vomiting tube after compression. However, the spring 8 can be set to further enhance the vertical restoring force of the device to ensure timely rebound after use. That is, when the cup lid 1 is pressed down, the spring 8 is compressed, and the spring 8 can be used to provide vertical restoring force to ensure that the vomiting tube 5 is reset, and the baffle 7 at its bottom blocks the round hole.
[0046] In one embodiment, such as Figure 2 As shown, the spring 8 is sleeved on the outer wall of the vomiting tube 5 and its upper and lower ends are connected to the cup lid 1 and the guide sleeve 41, respectively. Since the guide sleeve 41 is fixed to the partition 4 and the outer edge of the partition 4 is connected to the inner wall of the cup body 2, the spring 8 can be compressed when the cup lid 1 is pressed down, and it can also provide a vertical restoring force when the pressing stops.
[0047] In one embodiment, the spring 8 can also be sleeved on the outer wall of the guide sleeve 41 and its upper and lower ends are respectively connected to the cup lid 1 and the partition 4. The outer edge of the partition 4 is connected to the inner wall of the cup body 2, so when the cup lid 1 is pressed down, the partition 4 can provide vertical support force, which can compress the spring 8. When the pressing stops, it can also provide vertical restoring force.
[0048] In one embodiment, such as Figure 2 As shown, the baffle 7 has an upward protrusion at its center, forming a guide cone 71. The guide cone 71 allows vomit to enter and leave the drain outlet 6 more smoothly, preventing blockage of the vomiting tube 5.
[0049] In one embodiment, such as Figure 2As shown, the lower end of the drain outlet 6 is connected to the top surface of the baffle 7. Connecting the lower end of the drain outlet 6 to the top surface of the baffle 7 prevents residue from forming above the baffle 7 because the top surface of the baffle 7 is lower than the lower end of the drain outlet 6, ensuring that vomit is discharged from the drain outlet 6 as much as possible.
[0050] In one embodiment, such as Figure 2 As shown, the outer wall of the cup is equipped with a handle 9. This allows the user to hold the cup comfortably and prevents it from slipping off during use and causing damage.
[0051] In one embodiment, such as Figure 2 As shown, the upper end of the vomiting catheter 5 protrudes from the cup lid 1 and is connected to the cup lid 1 with a rounded transition. The design of the vomiting catheter 5 protruding from the cup lid 1 is ergonomic, making it easier for the patient to align the vomiting catheter 5 opening, reducing facial pressure points, increasing comfort, avoiding injury to the patient's face, and improving safety and hygiene. In addition, this design makes it easy to pour out the liquid inside the device, facilitating cleaning and thus increasing the service life of the device.
[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
