Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an emergency clinical emetic device. Background Art

[0002] Medical emesis is usually a treatment method used in emergency situations. For example, when poisoned or having ingested something by mistake, it is necessary to immediately remove the poison in the stomach. Medical emesis does not refer to encouraging or supporting spontaneous vomiting behavior, but is used as a medical first aid method. Common medical emesis methods include gastric lavage and using emetic drugs. However, the existing methods of using emetic drugs and gastric lavage both cause certain harm to the human body after use.

[0003] Currently, the method of using a tongue depressor or inserting a finger into the patient's throat is adopted for emesis. In this way, the tongue depressor or finger is likely to contuse the patient's throat, and the effect is poor. Most of the existing emetic devices stimulate the patient's tonsils to make the patient vomit and expel the poison in the stomach. When the patient is about to vomit under stimulation, the emetic device cannot be retracted in time. The body's stress response during vomiting will cause the patient's body to shake to a certain extent, resulting in the patient's mouth, tongue, teeth, etc. touching the emetic device and causing certain harm to the patient.

[0004] An emergency clinical emetic device with the Chinese authorized announcement number CN118058887B currently disclosed includes a bench, and also includes a stimulation component. The stimulation component includes an emetic part and a positioning rod. The emetic part is detachably installed at the end of the positioning rod; a first driving mechanism for driving the emetic part to move along the length direction of the positioning rod; a limiting mechanism, the limiting mechanism includes two symmetrically arranged expanding parts, one end of each of the two expanding parts is fixedly connected with a positioning cylinder, and one side of the positioning cylinder is connected with a driving component for driving it to rotate around its own axis; a second driving mechanism, one side of the second driving mechanism is connected with the first driving mechanism. After the first driving mechanism drives the emetic part to move along the length direction of the positioning rod into the patient's oral cavity, the second driving mechanism drives the emetic part to rotate around the axis of the positioning rod and reciprocate along the length direction of the positioning rod.

[0005] According to the above patent, when the patient is about to vomit under the stimulation of the emetic part, the patient can rotate the connecting cylinder. Under the action of the damping spring, the damping spring pulls the sliding frame to move, so that the support cylinder and the positioning rod retract synchronously. While the expanding parts are reset, the emetic part quickly retracts, avoiding the body shaking caused by the stress response of the patient during vomiting, resulting in the patient's mouth touching the device and getting injured. However, although the emetic part and the expanding parts can be reset, they cannot automatically leave the patient's mouth after reset, which is likely to affect the patient's vomiting process. Therefore, there is a need for an emetic device that can quickly reset the emetic part and safely withdraw from the patient's mouth. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses the expansion member to smoothly open the oral cavity without hurting the patient, so that the emetic member can smoothly enter and effectively stimulate the patient's throat to induce vomiting reflex. During the emetic process, the first resetting member and the second resetting member are in a standby state to immediately protect the patient from the phenomenon of back aspiration during vomiting.

[0019] When the patient feels a strong sense of nausea and is about to vomit, the control switch is pressed in advance, thereby controlling the emetic driver, the expansion driver and the retraction driver in sequence. Before the emetic device is retracted as a whole, the emetic component and the expansion component are in a reset state under the action of the first resetting component and the second resetting component, avoiding the retraction action from causing damage to the patient's oral cavity. This makes the vomiting process smooth, thereby avoiding the risk of vomitus blocking the airway and accidental inhalation, thereby ensuring the safety and effectiveness of the entire emetic process.

[0020] 2. After the patient's mouth is stretched open twice by two expansion pieces, the doctor inserts the emetic piece into the patient's mouth again. As the emetic piece is filled with clean water, the clean water flows into the inner cavity of the emetic part through the water inlet channel and is sprayed out from the water outlet holes on the surface of the emetic part to continuously rinse the patient's mouth.

[0021] As the clean water is sprayed into the patient's mouth, the inside of the patient's mouth is ensured to be thoroughly cleaned, residues are effectively removed, oral hygiene is maintained, and the patient's overall comfort is improved.

[0022] 3. The present invention realizes a slight vibration of the emetic component by a vibration device between the slider and the resistance rod, so that the emetic component is gentler than a large-scale movement, that is, the emetic part of the spherical structure and the patient's throat are gently released, reducing the discomfort and injury risk to the patient's throat.

[0023] At the same time, through the mutual repulsion between the first fixed magnet and the first movable magnet and the effect of the flexible extrusion layer, the resistance rod can stably position the vomiting member and can transmit the vibration source to the vomiting member through the vibration device. The triggering efficiency of the vomiting reflex is improved, and after the positioning is released, the compression spring can drive the resistance rod to quickly reset, thereby releasing the fixation of the vomiting member, so that the vomiting member can be quickly reset under the action of the first reset member, thereby improving the vomiting effect.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figures 1 - 8As shown, an emergency clinical emetic device comprises a support 1, an emetic member 2 arranged on the support 1, and expansion members 3 symmetrically arranged on both sides of the emetic member 2, wherein the support 1 is provided with an emetic driver 4 for driving the emetic member 2 to vibrate in the throat of a patient and an expansion driver for driving the two expansion members 3 to rotate in opposite directions to open the patient's mouth, and further comprises a retraction component for driving the support 1 to move so that the expansion member 3 and the emetic member 2 exit the patient's oral cavity, wherein the retraction component comprises a guide rail 5 and a retraction driver drivingly connected to the support 1 6. The support 1 is slidably arranged on the guide rail 5. The support 1 is provided with a first restoring member 11 capable of quickly moving the emetic member 2 away from the throat. The support 1 is provided with a second restoring member 12 capable of quickly closing the two expansion members 3. The guide rail 5 is provided with a control switch 51 electrically connected to the emetic driver 4, the expansion driver and the retraction driver 6. When the patient presses the control switch 51 before vomiting, the emetic member 2, the expansion member 3 and the support 1 are in the return state in turn, so that the emetic device can be completely away from the patient's mouth when the patient vomits.

[0037] The expansion drive is not shown in the figure.

[0038] When the doctor prepares the emetic device, the doctor adjusts it to the best position for insertion into the patient's mouth.

[0039] Before inducing vomiting, the doctor will set the working parameters of the vomiting driver 4 according to the specific situation of the patient, such as vibration frequency, amplitude, etc., to ensure that the patient's throat can be effectively stimulated to induce vomiting reflex. At the same time, the expansion driver is also set to an appropriate torque output to ensure that the expansion member 3 can smoothly open the patient's mouth without causing harm, and ensure that the vomiting member 2 has enough space to enter and work.

[0040] When everything is ready, the doctor will slowly push the support 1 together with the emetic component 2 and the expansion component 3 into the patient's oral cavity. At this time, the expansion component 3 will gradually rotate outward under the action of the expansion driver, gently spread the patient's upper and lower teeth, so that the emetic component 2 can accurately reach the patient's throat. As the emetic driver 4 drives the emetic component 2 to produce regular vibrations, it acts on the laryngeal mucosa through physical stimulation, activating the sensory nerve endings in this area, thereby triggering the vomiting center in the brain, causing nausea until vomiting is finally achieved.

[0041] During the vomiting process, the first restoring member 11 and the second restoring member 12 installed on the support 1 are in a standby state. Once the patient feels that he is about to vomit, the vomiting member 2 can be quickly moved away from the throat and the expansion member 3 can be closed, so that the patient can vomit smoothly without the occurrence of back aspiration due to blockage by vomitus.

[0042] When the patient feels a strong sense of nausea and is about to vomit, the patient presses the control switch 51 located on the guide rail 5 in advance, and the emetic driver 4, the expansion driver, and the retraction driver 6 are immediately activated. First, the emetic driver 4 releases the driving state of the emetic member 2, so that the emetic member 2 moves away from the patient's larynx under the action of the first reset member 11. Then the expansion driver releases the driving state of the expansion member 3, so that the two expansion members 3 close under the action of the second reset member 12. Finally, after receiving the signal, the retraction driver 6 runs in the reverse direction rapidly, pushing the support 1 to slide outward along the guide rail 5, and the emetic member 2 and the expansion member 3 attached thereto are also taken away from the patient's oral cavity. The reset actions of the emetic member 2, the expansion member 3, and the support 1 are carried out in sequence, avoiding damage to the patient's mouth caused by the retraction action of the entire emetic device, thereby effectively avoiding the risk of foreign objects being accidentally inhaled into the airway during emesis.

[0043] See Figures 1 - 8 As shown, the emetic member 2 is specifically a rod structure. A sleeve 21 is vertically provided on the support 1, and the emetic member 2 is inserted into the sleeve 21. A vomiting part 22 for contacting the patient's larynx is provided at the front end of the emetic member 2. The vomiting part 22 is a spherical structure. An anti - detachment ring 23 is provided at the rear end of the emetic member 2. The first reset member 11 is provided between the anti - detachment ring 23 and the support 1. The first reset member 11 is a spring structure. When the doctor pushes the emetic member 2 to move until the vomiting part 22 contacts the patient's larynx, the first reset member 11 is in a compressed state.

[0044] When the doctor pushes the emetic member 2, the emetic member 2 moves forward along the vertical sleeve 21 on the support 1, and the spherical vomiting part 22 at the front end gradually approaches and finally contacts the patient's larynx. The spherical structure of the vomiting part 22 avoids unnecessary harm to the patient due to its smooth surface.

[0045] Meanwhile, the first reset member 11 between the anti - detachment ring 23 at the rear end of the emetic member 2 and the support 1 is gradually compressed, accumulating elastic potential energy to prepare for the subsequent rapid reset. Once the vomiting part 22 accurately touches the larynx, the doctor stops pushing. The emetic driver 4 keeps the vomiting part 22 in contact with the larynx and applies vibration until the emetic operation is completed.

[0046] See Figures 1 - 8 As shown, a rubber sleeve 221 is provided at the connection between the emetic member 2 and the vomiting part 22. A rubber pad 222 capable of supporting the rubber sleeve 221 to buffer the reset impact force of the vomiting part 22 is provided on the sleeve 21. Elastic draw ropes 2211 for further resetting the vomiting part 22 are provided between both sides of the rubber sleeve 221 and the support 1. When the vomiting part 22 contacts the patient's larynx, the elastic draw ropes 2211 are in a stretched state.

[0047] When the emetic part 22 is in contact with the patient's larynx, the first resetting member 11 is in a compressed state, and the elastic drawstring 2211 is in a stretched state.

[0048] When the emetic part 22 moves away from the patient's larynx under the action of the first resetting member 11 and the elastic drawstring 2211, the rubber sleeve 221 at the connection between the emetic member 2 and the emetic part 22 contacts the rubber pad 222 on the sleeve 21, and the rubber pad 222 plays a buffering role to reduce the impact force when the emetic part 22 resets.

[0049] The elastic drawstring 2211 provides additional resetting assistance for the emetic part 22 to ensure that the emetic part 22 can reset smoothly and quickly, improving the reset speed.

[0050] See Figures 1 - 8 and Figure 10 As shown in

[0051] and

[0052] shown, the emetic member 2 has a water inlet channel 24 penetrating through both ends thereof, the emetic part 22 has an inner cavity 223 communicating with the water inlet channel 24, and water outlet spray holes 2231 communicating with the inner cavity 223 are formed on the surface of the emetic part 22. When the patient's mouth is secondarily opened by the two expansion members 3 after vomiting, the patient's oral cavity is in a state of being cleaned by the water sprayed from the emetic part 22.

[0053] See Figures 4 - 9 shown, the emetic driver 4 includes a positioning structure 41 disposed between the two expansion members 3 for keeping the emetic part 22 in contact with the patient's larynx and a vibration device 42 for transmitting the vibration force to the emetic member 2 through the positioning structure 41.

[0054] The specific structure of the vibration device 42 is not shown in the figure.

[0055] When the emetic driver 4 works, the positioning structure 41 disposed between the two expansion members 3 ensures that the emetic part 22 is stably in contact with the patient's larynx.

[0056] Meanwhile, the vibration force generated by the vibration device 42 is transmitted to the emetic member 2 through the positioning structure 41, enabling the emetic part 22 to generate slight vibrations while in contact with the larynx, enhancing the emetic effect and improving the operation stability.

[0057] See Figures 4 - 9 As shown, the positioning structure 41 has a contact rod 411 slidably arranged on each expansion member 3 and a linear actuator 412 arranged on each expansion member 3 for driving the corresponding contact rod 411 to move. The end of the contact rod 411 extending towards the emetic member 2 is provided with a flexible extrusion layer 4111, and the outward extending end of the contact rod 411 is in transmission connection with the linear actuator 412.

[0058] When the positioning structure 41 works, the contact rod 411 slidably arranged on each expansion member 3 is driven by the linear actuator 412 to move. The end of the contact rod 411 extending towards the emetic member 2 is provided with a flexible extrusion layer 4111 to ensure softness when contacting the patient's throat.

[0059] As the emetic member 2 is clamped between the two flexible extrusion layers 4111, the movement of the emetic member 2 is restricted, and the position where the emetic part 22 contacts the throat is maintained.

[0060] See Figures 4 - 9 As shown, the linear actuator 412 has a slide rail 4121 extending outward from the expansion member 3 and a slider 4122 slidably arranged on the slide rail 4121 and connected to the contact rod 411. The outward extending end of the slide rail 4121 is provided with a first fixed magnet 4123, the slider 4122 is provided with a first movable magnet 4124, and a compression spring 4125 is arranged between the slider 4122 and the guide rail 5. When the contact rod 411 contacts the emetic member 2 through the flexible extrusion layer 4111, the first fixed magnet 4123 and the first movable magnet 4124 are in a mutually repulsive state, and the compression spring 4125 is in a simultaneously stretched state.

[0061] Both the first fixed magnet 4123 and the first movable magnet 4124 are electromagnets.

[0062] When the contact rod 411 contacts the emetic member 2 through the flexible extrusion layer 4111, the slider 4122 on the linear actuator 412 slides along the slide rail 4121, and the compression spring 4125 between the slider 4122 and the slide rail 4121 is in a stretched state. At the same time, a mutually repulsive magnetic force is generated between the first fixed magnet 4123 at the outward extending end of the slide rail 4121 and the first movable magnet 4124 on the slider 4122, further enhancing the tensile force of the slider 4122 to ensure that the contact rod 411 can stably and softly contact the emetic member 2.

[0063] When the patient presses the control switch 51, both the first fixed magnet 4123 and the first movable magnet 4124 are powered off. Under the action of the compression spring 4125, the slider 4122 is reset, driving the abutting rod 411 to retract away from the emetic member 2. Since the positioning state of the emetic member 2 is released, under the action of the first reset member 11, the emetic part 22 quickly moves away from the patient's throat, achieving a quick reset effect.

[0064] See Figures 4 - 9 As shown, a vibration device 42 is connected between the slider 4122 and the abutting rod 411, and a gap is left between the abutting rod 411 and the slider 4122 for the vibration device 42 to trigger the relative movement of the abutting rod 411 with respect to the slider 4122.

[0065] When the vibration force generated by the vibration device 42 during operation is transmitted to the abutting rod 411, the abutting rod 411 can generate slight vibration and displacement while remaining connected to the slider 4122, thereby ensuring that the emetic part 22 can effectively transmit vibration and enhance the emetic effect.

[0066] Compared with large - scale movement, the small - scale vibration of the emetic part 22 is gentler to the patient's throat, can act on the patient's throat at a high frequency within a small range, and helps to more effectively trigger a physiological reaction.

[0067] See Figures 4 - 9 As shown, the expansion member 3 is in a plate - like structure. One end of the expansion member 3 is rotatably connected to the support 1, and the other end of the expansion member 3 extends outward. A rubber strip 31 for the patient's teeth to touch is provided at the end of each expansion member 3 that extends outward. A second reset member 12 is provided between both sides of each expansion member 3 and the support 1. The second reset member 12 is a spring structure. When the two expansion members 3 expand the patient's mouth outward, the second reset member 12 is in a compressed state.

[0068] When the two expansion members 3 expand the patient's mouth outward, the plate - like structure of the expansion member 3 unfolds around the rotation connection point with the support 1. When the patient opens the mouth and bites the expansion member 3, the patient's teeth come into contact with the rubber strip 31, ensuring that the patient's teeth can firmly bite on the rubber strip 31 and preventing damage to the patient's teeth.

[0069] At the same time, the second reset member 12 between both sides of each expansion member 3 and the support 1 is compressed, storing elastic potential energy. When the expansion member 3 resets, the two expansion members 3 are quickly closed by the resilience of the second reset member 12 to ensure that the expansion member 3 does not cause damage to the oral cavity in the unfolded state when it exits the patient's oral cavity.

[0070] See Figures 1 - 4As shown in the figure, the retraction driver 6 has a second fixed magnet 61 provided at the front end of the guide rail 5 and a second movable magnet 62 provided on the support 1. A limit plate 63 for supporting the support 1 after it returns to its position is provided at the rear end of the guide rail 5. A buffer cushion layer 631 is provided on the limit plate 63. When the control switch 51 is not activated, the second fixed magnet 61 and the second movable magnet 62 are in a state of mutual attraction. When the control switch 51 is activated, the second fixed magnet 61 and the second movable magnet 62 are in a state of mutual repulsion.

[0071] Both the second fixed magnet 61 and the second movable magnet 62 are electromagnets.

[0072] When the control switch 51 is not activated, the second fixed magnet 61 provided at the front end of the guide rail 5 and the second movable magnet 62 provided on the support 1 are in a state of mutual attraction, causing the support 1 to closely adhere to the front end of the guide rail 5.

[0073] When the control switch 51 is activated, the current direction between the second fixed magnet 61 and the second movable magnet 62 changes, resulting in a state of mutual repulsion between the two. As a result, the support 1 is pushed along the guide rail 5 towards the limit plate 63 until the limit plate 63 supports the support 1. At this time, both the emetic member 2 and the dilator 3 follow the support 1 to withdraw from the patient's oral cavity, achieving the retraction action and ensuring an unobstructed state for the patient during vomiting.

[0074] In the present invention, the first reset member 11 and the second reset member 12 are in a standby state during the emetic process, immediately protecting the patient from the phenomenon of backflow during vomiting. When the patient feels a strong sense of nausea and is about to have a vomiting reaction, the control switch 51 is pressed in advance. Before the overall retraction of the emetic device, the emetic member 2 and the dilator 3 quickly return to their original positions under the action of the first reset member 11 and the second reset member 12, avoiding damage to the oral cavity caused by the retraction action, ensuring a smooth vomiting process, and avoiding the risk of vomitus blocking or being accidentally aspirated into the airway.

[0075] In addition, after the two dilators 3 expand the patient's mouth for the second time, the doctor can insert the emetic member 2 again and fill it with cleaning water. The cleaning water is sprayed out from the water outlet spray holes 2231 through the water inlet channel 24 to thoroughly clean the inside of the oral cavity, remove residues, and improve the patient's comfort and hygiene conditions.

[0076] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
