Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a soft oral gastric lavage opening device. Background Technology

[0002] A mouth opener, also known as a trismus device, is an instrument used to open the mouth of patients with trismus, difficulty breathing, or impaired consciousness, for purposes such as gastric lavage or suctioning. Existing mouth openers are U-shaped, with a handle fixed to each of the two ends. The mouth opener body is elastic; when subjected to external pressure, the two side arms can bend inwards or outwards, and when the external pressure is removed, the two side arms return to their original position.

[0003] Chinese patent application number CN202322369839.X discloses an oral cavity opener, comprising an opening assembly and a bite assembly. The opening assembly is used to open the patient's oral cavity, and the bite assembly is used to support the patient's oral cavity, keeping the patient's oral cavity in an open state to facilitate the insertion of a gastric tube. The opening assembly includes a first opening plate, a second opening plate, and a driving mechanism. The first opening plate is a fixed plate and cannot move, while the second opening plate is a movable plate that can move to increase or decrease the distance between the first and second opening plates. Both the first and second opening plates are connected to the driving mechanism. The oral cavity opener provided by this utility model allows for fewer obstacles near the patient's oral cavity, thus facilitating the insertion of a gastric tube by medical personnel.

[0004] Regarding the aforementioned techniques, the fixation method mainly relies on elastic bands, which are not very secure. During medical staff operation, this may cause the tube to shift during intubation, making intubation difficult. In emergency situations, repeated intubation not only wastes time but may also increase the patient's pain and discomfort. More importantly, repeated intubation can easily damage the nasal, pharyngeal, and esophageal mucosa, increasing the risk of infection. Utility Model Content

[0005] The purpose of this invention is to provide a soft oral gastric lavage mouth opening device, which aims to solve the problem that traditional mouth opening devices are not securely fixed and are prone to displacement, making it inconvenient for medical staff to operate and posing safety hazards to patients.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A soft oral gastric lavage mouth opener includes a mouth opener body, characterized in that a tongue depressor plate is integrally formed at one end of the mouth opener body, and hooks are provided on both opposite sides of the mouth opener body. Non-woven fabric loops are connected to the hooks, and the non-woven fabric loops have ear holes for the ears to pass through. The ends of the two non-woven fabric loops away from the hooks are connected to a fastening member.

[0008] In one alternative: the hook is an S-shaped hook, and the non-woven fabric loop is detachably attached to the body of the opening device via the hook.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0023] Example 1:

[0024] like Figures 1-2 As shown, this utility model provides a soft oral gastric lavage mouth opener, which includes a mouth opener body 1. The mouth opener body 1 is made of medical plastic, specifically PVC, PP, PE, etc. A tongue depressor 2 is integrally formed at one end of the mouth opener body 1. Hooks 3 are provided on both opposite sides of the mouth opener body 1. Non-woven fabric ear loops 4 are connected to the hooks 3. The non-woven fabric ear loops 4 have ear holes 41 for the ear to pass through. The ends of the two non-woven fabric ear loops 4 away from the hooks 3 are connected to a fastening member 5.

[0025] When medical staff need to perform gastric lavage on a patient, the mouth opener body 1 is gently placed into the patient's mouth. The hooks and clamping device 5 are used to fix the mouth opener to the patient's head, ensuring that the mouth opener can stably open the oral cavity. At this time, the tongue depressor 2 will naturally press down on the patient's tongue to prevent the tongue from falling back or obstructing intubation. Through the combined action of the tongue depressor 2 and the mouth opener, the obstructed pharyngeal passage can be successfully opened, solving the problem of difficult intubation in clinical practice and greatly improving the success rate of first-time intubation.

[0026] The non-woven fabric ear loops 4 allow the patient's ear to pass through the ear hole 41, providing excellent positioning and effectively preventing lateral displacement of the mouth opener body 1 during wear. Furthermore, the design of the outer edge of the non-woven fabric ear loops 4 being at least 10mm from the ear hole 41 reduces the feeling of tightness on the patient's ear, improving wearing comfort. The tightening element 5 then secures the two non-woven fabric ear loops 4, further reducing the possibility of the mouth opener body 1 falling off during surgery. The design of the non-woven fabric ear loops 4 and the tightening element 5 ensures the mouth opener is stably fixed to the patient's head, preventing it from falling off or shifting during gastric lavage. Simultaneously, the non-woven fabric ear loops 4 and the tightening element 5 facilitate operation and adjustment by medical staff. These features effectively solve the problems of traditional mouth openers being unstable and prone to displacement, making gastric lavage procedures more convenient for medical staff. The mouth opener material is also softer than that of commonly used mouth openers, reducing patient discomfort and safety risks.

[0027] Specifically, such as Figures 1-3 The hook 3 shown is set as an S-shaped hook, and the non-woven fabric ear 4 is detachably attached to the mouth opener body 1 through the hook 3. This design makes the mouth opener very flexible and stable during use. Medical staff can adjust the position of the non-woven fabric ear 4 on the S-shaped hook according to the size and shape of the patient's mouth to ensure that the mouth opener can fit tightly in the patient's mouth.

[0028] And such as Figures 1-3 The free end of the tongue depressor 2 is arc-shaped, facing away from the middle of the mouth opening device body 1. The arc-shaped tongue depressor 2 can better fit the patient's tongue and oral cavity structure, reducing the discomfort caused to the patient. At the same time, the arc-shaped tongue depressor 2 can better fix the tongue and prevent the tongue from moving or falling back during the intubation process. This helps to keep the pharynx open and improve the success rate of intubation. In addition, the arc-shaped tongue depressor 2 may provide a more natural intubation path for the gastric tube, reducing the resistance and difficulty during intubation. This helps medical staff to perform gastric lavage more smoothly.

[0029] In addition, such as Figures 1-2 As shown, the fastening element 5 can be any one of Velcro, elastic cord, or cotton rope, which can be selected according to specific usage needs and scenarios to meet different fixing and binding requirements and facilitate the operation of medical staff.

[0030] Example 2:

[0031] like Figures 1-4 As shown, the difference between this embodiment and Embodiment 1 is that:

[0032] The mouthpiece body has a tooth-cushioning platform 6 at the end facing the tongue depressor 2. The tooth-cushioning platform 6 is usually made of a soft and elastic material, such as medical-grade silicone or plastic. The design of the tooth-cushioning platform 6 can increase the contact area of ​​the mouthpiece in the oral cavity, thereby improving its stability and further preventing the mouthpiece from falling off or shifting during gastric lavage and other procedures, ensuring the smooth progress of the operation.

[0033] And such as Figures 1-4 As shown, the tooth-mounting platform 6 is tapered along the opening direction of the mouth opener body 1. The tapered tooth-mounting platform 6 can better adapt to oral cavity of different sizes and shapes. Due to the gradual tapering of the cone, it can fit more closely to the patient's teeth and gums, reducing gaps and improving the stability of the mouth opener. At the same time, the tapered tooth-mounting platform 6 provides medical staff with a clearer insertion path. During procedures such as gastric lavage, medical staff can more easily see and avoid teeth, ensuring that the gastric tube or other instruments can be inserted smoothly.

[0034] And as Figures 1-4 As shown, the overall cross-section of the mouth opener 6 is elliptical. The elliptical cross-section design allows the mouth opener 6 to fit better on the patient's teeth. Especially for patients with irregular tooth arrangement or special oral cavity shape, this design provides a larger contact area, thereby enhancing the stability of the mouth opener in the oral cavity. Furthermore, the elliptical cross-section design of the mouth opener 6 provides better adaptability and stability for the mouth opener, while reducing patient discomfort. This design also facilitates operation by medical staff and protects the patient's teeth.

[0035] At the same time, such as Figures 1-4 As shown, the outer peripheral surface of the tooth-mounting platform 6 is provided with a tooth groove 61 for tooth insertion and positioning. The design of the tooth groove 61 on the outer peripheral surface of the tooth-mounting platform 6 provides better fit and stability for the mouth opener, while improving patient comfort and the ease of operation for medical staff.

[0036] The specific working effects of this utility model are as follows:

[0037] When using the device, gently place the mouth opener body 1 into the patient's mouth, and use the loops and clamping device 5 to fix the mouth opener to the patient's head, ensuring that the mouth opener can stably open the oral cavity. At this time, the tongue depressor 2 will naturally press on the patient's tongue to prevent the tongue from falling back or obstructing intubation. Through the combined action of the tongue depressor 2 and the mouth opener, the obstructed pharyngeal passage can be successfully opened, solving the problem of difficult intubation in clinical practice and greatly improving the success rate of first-time intubation.

[0038] The non-woven fabric ear loops 4 allow the patient's ear to pass through the ear hole 41, providing excellent positioning and effectively preventing lateral displacement of the mouth opener body 1 during wear. Furthermore, the design of the outer edge of the non-woven fabric ear loops 4 being at least 10mm from the ear hole 41 reduces the feeling of tightness on the patient's ear, improving wearing comfort. The tightening element 5 then secures the two non-woven fabric ear loops 4, further reducing the possibility of the mouth opener body 1 falling off during surgery. The design of the ear loops and tightening element 5 ensures the mouth opener is stably fixed to the patient's head, preventing it from falling off or shifting during gastric lavage. Simultaneously, the non-woven fabric ear loops 4 and tightening element 5 facilitate operation and adjustment by medical staff. This effectively solves the problem of traditional mouth openers being unstable and prone to displacement, making gastric lavage procedures more convenient for medical staff. The mouth opener material is softer than that of commonly used mouth openers, reducing patient discomfort and safety risks.
