Description

Technical Field

[0001] This invention belongs to the field of emetic technology, specifically referring to an emetic device for use in the emergency department. Background Technology

[0002] In medical emergencies (such as gastric lavage after poisoning) or before certain examinations, it is often necessary to induce vomiting in patients. Traditional methods of inducing vomiting mostly rely on medical staff using tools such as tongue depressors to directly stimulate the patient's throat, or instructing the patient to stimulate it themselves. This method has significant drawbacks: First, the intensity, frequency, and location of stimulation are difficult to control precisely, resulting in inconsistent effects and potential damage to the throat mucosa; second, the procedure causes great discomfort and fear for the patient, leading to low cooperation; third, when vomiting occurs, the vomit and its volatile irritating odor quickly contaminate the examination room environment, causing discomfort to those around them, potentially leading to cross-infection and psychological burden, seriously affecting the operational experience and work efficiency of medical staff.

[0003] Existing technologies have also developed some emetic aids in an attempt to address some of the problems. For example, some devices simulate stimulation through mechanical structures. However, these devices are often single-function and have significant shortcomings: First, they cannot flexibly adapt to patients of different heights, leading to discomfort during use, affecting the emetic effect and increasing pain; second, the movement frequency of their stimulation components is usually fixed and cannot be adjusted according to individual differences in the patient's sensitivity to pharyngeal stimulation, resulting in overstimulation for sensitive individuals and poor emetic effect for insensitive individuals, leading to low efficiency; third, they generally lack effective mechanisms for handling the harmful odors produced during vomiting, failing to improve the harsh operating environment.

[0004] Therefore, there is an urgent need in the field for an integrated emetic device that can achieve personalized adaptation, intelligent adjustment of stimulation parameters, and effective air purification, in order to overcome the above-mentioned defects of the prior art. Summary of the Invention

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. High degree of personalization and user-friendly experience: Height adaptation: By setting a height-adjustable electric actuator, the support plate can be raised and lowered, easily adapting to patients of different heights. This allows the patient's upper body to bend in a more natural and comfortable posture and fit the mask, reducing additional pain caused by discomfort in the body position and improving the versatility and humanistic care of the device. Adjustable stimulation frequency: Through a unique adjustable cam linkage mechanism (specifically, by moving the position of the adjusting stud in the adjusting slot to change the distance between the two adjusting studs), the reciprocating motion interval of the pharyngeal stimulation rod is infinitely adjustable. This design allows medical staff to accurately set the most effective stimulation frequency according to the different patients' sensitivity to pharyngeal stimulation, avoiding insufficient or excessive stimulation, and significantly improving the success rate and efficiency of vomiting. 2. Revolutionary improvement in the operating environment: Innovatively integrating an air purifier, the device allows for bidirectional airflow control through simple squeezing and releasing of the pressure bag by medical staff. When squeezed, the airflow blows the fragrance pad, causing the fresh scent to diffuse rapidly, effectively neutralizing and masking the pungent odor of vomit, purifying the air in the examination room, greatly alleviating discomfort for patients and medical staff, and preventing a chain reaction of nausea. When released, the generated negative pressure is used to assist in suction through the patient's mouth and nose via a mask. This negative pressure environment itself also serves as an auxiliary stimulus, further enhancing the emetic effect. 3. Excellent hygiene and ease of use: The combination of a pull-out collection box and medical waste bags makes the collection and disposal of vomit simple and hygienic, effectively preventing leakage and cross-infection. Key contact components, such as the mask and pharyngeal stimulation stick, are designed to be detachable for thorough cleaning and disinfection, ensuring safe reuse of the device and meeting stringent medical and health standards. The entire operation process is integrated and mechanized, which reduces the labor intensity and operational difficulty for medical staff. At the same time, physical isolation reduces direct contact with patients' vomit, ensuring the safety of medical staff. Attached Figure Description

The stimulation balloon 21 is located on the detachable bendable rod 20. A locking post 22 is provided on the detachable bendable rod 20. A locking cavity 23 is provided on the telescopic rod 8. A locking channel 24 is provided on the side wall of the locking cavity 23. The disassembly bending rod 20 is snapped into the snap-fit ​​cavity 23, and the snap-fit ​​post 22 is snapped into the snap-fit ​​channel 24; the drive adjustment component 5 includes a feed electric push rod 25, a fixed block 26, a drive disk 27, and a drive motor 28.

The drive motor 28 is mounted on the fixed block 26, and the output end of the drive motor 28 is connected to the drive disk 27.

[0025] like Figure 1 , Figure 17 , Figure 18 As shown, the vomit collection device 4 includes a pull-out collection box 51, a locking protrusion 52, and a locking slide rail 53. The locking protrusion 52 is located on the upper wall of the pull-out collection box 51, and the locking slide rail 53 is located on the bottom wall of the support plate 56. The locking protrusion 52 is locked and slidably disposed in the locking slide rail 53.

[0026] In practical use, a medical waste bag is placed in the pull-out collection box 51. Based on the height of the person to be induced to vomit, the height-adjusting electric actuator 55 is activated. The height-adjusting electric actuator 55 extends and retracts, causing the support plate 56 to rise and fall to accommodate different patient heights. This causes the patient's upper body to bend and their face to fit the mask 32. The feed electric actuator 25 is then activated. The feed electric actuator 25 extends and retracts, causing the fixing block 26 to move. The movement of the fixing block 26 causes the L-shaped support rod 15 to move. The movement of the L-shaped support rod 15 causes the locking fixing plate 18 to move. The movement of the locking fixing plate 18 causes the telescopic rod 8 to move. The movement of the telescopic rod 8 causes the pharyngeal stimulation balloon 10 to move until the stimulation balloon 21 contacts the patient's throat. The drive motor 28 is then activated, and its rotation drives the... When the rotating disc 27 rotates, and the incomplete protrusion 29 contacts the adjusting stud 13, it pushes the adjusting stud 13 to move closer to the mask 32. The movement of the adjusting stud 13 causes the arc-shaped bent plate 11 to move closer to the mask 32. The movement of the arc-shaped bent plate 11 causes the telescopic rod 8 to move closer to the mask 32. The movement of the telescopic rod 8 causes the detachable bent rod 20 to move towards the patient's pharynx. The movement of the detachable bent rod 20 causes the stimulation balloon 21 to stimulate the patient's pharynx. When the incomplete protrusion 29 disengages from the adjusting stud 13, the adjusting stud 13 moves away from the mask 32 under the action of the spring 17, which in turn causes the telescopic rod 8 to move away from the mask 32. The movement of the telescopic rod 8 causes the detachable bent rod 20 to move away from the patient. The detachable, bendable rod 20 moves, causing the stimulation balloon 21 to move away from the patient's pharynx. This cycle repeats, inducing a gagging sensation. Since different patients have varying sensitivities to pharyngeal stimulation, a fixed reciprocating time cannot meet the needs of different patients. The pharyngeal stimulation device 3 can adjust the reciprocating interval according to the patient's sensitivity. By rotating the locking nut 14 and loosening the adjusting stud 13, the position of the adjusting stud 13 in the adjusting groove 12 is adjusted. A greater distance between the two adjusting studs 13 results in a longer reciprocating interval, and vice versa. This achieves the technical effect of adjusting the reciprocating interval, better meeting the needs of different patients and enhancing the efficiency of vomiting. During vomiting, the volatile vomit stimulates... The pungent odor can spread rapidly, causing the examination room environment to deteriorate, making people around feel uncomfortable, and may even trigger a chain reaction of nausea in other patients. At the same time, the pungent odor also brings great psychological burden to the medical staff. The air freshener 33 can solve the above problems. When the medical staff squeezes the pressure bag 38, the gas is transmitted to the lower cavity through the gas transmission hose 37, pushing the piston 35 to move upward and press the gas into the negative pressure tube 31. The inhalation sealing ball 49 presses the inhalation limiting ring 50 to prevent the gas from entering the mask 32, while the exhaust sealing ball 41 is blown away from the exhaust limiting ring 40, the exhaust pipe 39 is opened, and the gas blows the fragrance plate 44, allowing the fragrance to spread rapidly, thereby freshening the surrounding air and reducing the pain of the medical staff.When medical staff release the pressure bag 38, the piston 35 moves downward under the action of the negative pressure spring 36, causing the negative pressure tube 31 to generate negative pressure suction. At this time, the inhalation sealing ball 49 moves away from the inhalation limiting ring 50, and the negative pressure tube 31 connects with the mask 32, achieving the technical effect of negative pressure suction-assisted vomiting. When the patient feels nauseous, the pull-out collection box 51 can be pulled out randomly to induce vomiting. After vomiting, the medical waste bag can be collected. The mask 32 and the pharyngeal stimulation ball rod 10 can be disassembled for cleaning and disinfection. The above is the specific working process of this invention. This step can be repeated for the next use.
