Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anesthesia laryngoscope cover. Background Art

[0002] An anesthetic laryngoscope is a medical device inserted through the mouth or nose into the patient's throat during laryngeal surgery or examination, allowing the doctor to observe laryngeal lesions or administer treatment. It can be used to diagnose and treat laryngeal conditions such as vocal cord polyps, vocal cord paralysis, vocal cord nodules, vocal cord leukoplakia, and vocal cord inflammation. It can be used under general or local anesthesia. Before surgery or examination, the patient must be adequately prepared and anesthetized to ensure the safety and effectiveness of the procedure.

[0003] However, during anesthesia laryngoscope examination, since the laryngoscope blade is expensive and not suitable for disposable use, most of the current tracheal intubation operations use disposable laryngoscopes. However, their high strength will greatly affect the effect of the operation, and it will increase the cost, thereby greatly increasing the medical burden on patients. Therefore, most still use reusable laryngoscopes for surgery. In order to protect the laryngoscope, disposable laryngoscope covers are often used clinically, and the laryngoscope covers are put on high-end laryngoscope blades for use. However, the disposable laryngoscope covers currently used in clinical practice are not only hard, but also have relatively single functions and cannot meet the needs of laryngoscope blades of different specifications and sizes.

[0004] Therefore, there is a need for an anesthesia laryngoscope cover that can adapt to laryngoscopes of different sizes, provide support for the patient's mouth, and improve the effect of laryngoscopy. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes an anesthesia laryngoscope cover, which has the characteristics of strong adaptability and easy operation.

[0006] In order to achieve the above objectives, the present invention proposes the following specific solutions:

[0007] An anesthesia laryngoscope cover comprises a rectangular tube, a laryngoscope cover body is fixed in the middle of one side wall of the rectangular tube, the laryngoscope cover body is connected to the inner side of the rectangular tube, an observation slot is provided at one end of the laryngoscope cover body, a transparent glass plate is fixed to the inner wall of the observation slot, a receiving slot is provided at the edge of the inner top surface of the rectangular tube, a threaded tube is fixed at the edge of the top surface of the rectangular tube, the threaded tube is connected to the inner side of the receiving slot, an extrusion screw is threadedly connected to the inner side of the threaded tube, a connecting rod is fixed to the lower end of the extrusion screw, a limiting disk is fixed to the lower end of the connecting rod, an extrusion plate is movably inserted into the inner side of the receiving slot, and the extrusion plate A connecting hole is provided in the middle of the top surface, and a limiting groove is provided at the lower end of the connecting hole. The limiting plate is movably sleeved on the inner side of the limiting groove. The connecting rod passes through the connecting hole, and a fixing bracket is fixed on the other side of the top surface of the rectangular tube. A rotating hole is provided in the middle of the top surface of the fixing bracket, and a rotating rod is movably inserted into the inner side of the rotating hole. A threaded column is fixed at the lower end of the rotating rod, and a movable plate is threadedly connected to the outer side of the threaded column. The movable plate is movably inserted into the inner side of the fixing bracket, and a fixed plate is fixed at one end of the movable plate. The fixed plate is located on one side of the rectangular tube, and a second mouth pad is fixed to the edge of one side wall of the fixed plate.

[0008] As an optimal technical solution for the anesthesia laryngoscope cover of the utility model, a threaded hole is provided on the top surface of the movable plate, and the threaded column is threadedly connected to the inner side of the threaded hole.

[0009] As an optimal technical solution for the anesthesia laryngoscope cover of the utility model, a first pad is fixed to the middle of the bottom surface of the extrusion plate.

[0010] As an optimal technical solution for the anesthesia laryngoscope cover of the utility model, a second pad is fixed to the edge of the inner bottom surface of the rectangular tube.

[0011] As an optimal technical solution for an anesthesia laryngoscope cover of the utility model, a first mouth pad is fixed to an edge of one side wall of the rectangular tube.

[0012] As an optimal technical solution of an anesthesia laryngoscope cover of the present invention, a protective ring is fixed at one end of the laryngoscope cover body.

[0013] As an optimal technical solution for an anesthesia laryngoscope cover of the present invention, the laryngoscope cover body, the protective ring, the first pad and the second pad are all made of flexible materials.

[0014] As an optimal technical solution for the anesthesia laryngoscope cover of the utility model, the size of the extrusion plate is adapted to the size of the storage slot.

[0015] Compared with the existing technology, the utility model has the following beneficial effects:

[0016] The laryngoscope cover body of the present invention can wrap and protect the laryngoscope blade. The laryngoscope blade is inserted into the interior of the laryngoscope cover body through the rectangular tube, and then the extrusion screw is turned to make the first pad on the bottom surface of the extrusion plate cooperate with the second pad on the inner bottom surface of the rectangular tube to squeeze and fix the laryngoscope blade, ensuring that the laryngoscope cover body will not fall off during use. For laryngoscope blades of different specifications and sizes, the distance between the first pad and the second pad can be controlled by the extrusion screw to fix laryngoscope blades of different sizes. In addition, the laryngoscope cover body is made of flexible material and can adapt to laryngoscope blades of different sizes through a certain degree of expansion and contraction. It has strong adaptability. In addition, this solution also ensures that the laryngoscope blade does not directly contact the patient during anesthesia laryngoscope examination. It only needs to replace a new laryngoscope cover for reuse, avoiding the problems of difficult disinfection and high replacement cost of laryngoscope blades.

[0017] The utility model supports the patient's mouth by providing a first mouth pad and a second mouth pad. After anesthesia, the patient may not be able to control the movement of the mouth independently. If the patient bites the laryngoscope cover body with his teeth, it may damage the laryngoscope cover body made of flexible material and contaminate the laryngoscope lens. Therefore, in this solution, the patient's upper and lower teeth bite the first mouth pad and the second mouth pad respectively to avoid damaging the laryngoscope cover body. The patient's mouth can also be opened. By rotating the rotating rod, the threaded column is driven to rotate, and the movable plate drives the second mouth pad to move, so as to control the size of the patient's mouth opening, which is more convenient for doctors to perform examinations.
