Description

Technical Field

[0001] The utility model relates to the technical field of gastroscope laryngeal masks, in particular to a disposable protective cover for a gastroscope laryngeal mask. Background Technique

[0002] A gastroscope is a medical examination method and also refers to the instrument used for this examination. Gastroscope examination can directly observe the true situation of the examined part. Moreover, through pathological biopsy and cytological examination of suspicious lesion sites, a more definite diagnosis can be made. It is the preferred examination method for upper digestive tract lesions. It uses a slender and flexible tube to extend into the stomach, and doctors can directly observe the lesions of the esophagus, stomach, and duodenum, especially for tiny lesions. A gastroscope laryngeal mask is a special artificial airway management technique, which is widely used in clinical practice, especially in painless gastroscopy and colonoscopy treatments, providing effective support for airway management. It is usually made of silicone or plastic. The front-end ventilation mask is oval in shape, which can surround the epiglottis and glottis to form a sealed ventilation space, ensuring that the patient can effectively ventilate and be anesthetized during the examination or treatment process;

[0003] In the "Laryngeal Mask for Painless Gastroscopy Diagnosis and Treatment" with the publication number CN213432369U, it includes a pharyngeal balloon, a pharyngeal trachea, and a gastroscope tube. The inner side wall of the pharyngeal balloon forms a circular trumpet opening. The opening size of the pharyngeal balloon is not less than the bottom size. It also includes at least one anesthetic liquid catheter. The front-end part of the anesthetic liquid catheter fits on the left or right side wall of the pharyngeal balloon. The rear-end part of the anesthetic liquid catheter extends outwards. The front-end part of the anesthetic liquid catheter is evenly provided with a plurality of side holes along the length direction. Each side hole faces the side wall of the pharyngeal balloon and forms an angle with the side wall of the pharyngeal balloon at the same time. The angle of the angle is 25-45°. The anesthetic liquid rushes out from each side hole and splashes onto the front of the pharyngeal balloon after hitting the side wall of the pharyngeal balloon, which not only avoids the anesthetic liquid directly flushing the patient's throat but also makes the anesthetic liquid evenly splash onto the front of the pharyngeal balloon;

[0004] Before the above-mentioned gastroscope laryngeal mask is used for examination, the sealing protective film of the gastroscope laryngeal mask is directly torn off, and then basically the gastroscope laryngeal mask is placed on the examination table in a naked state. However, this direct placement method is prone to falling and damage due to the accidental touch of medical staff, which is not convenient for the medical staff to assist in examining the patient's stomach later and is not convenient for the stable examination and use of the gastroscope laryngeal mask later;

[0005] Therefore, we propose a disposable protective cover for a gastroscope laryngeal mask, which can well solve the above problems. Summary of the Invention

[0006] The purpose of the present utility model is to provide a disposable protective cover for a gastroscope laryngeal mask, so as to solve the problems raised in the above background technology. Currently, on the market, the sealing protective film of the gastroscope laryngeal mask is directly torn off, and then the gastroscope laryngeal mask is basically placed on the examination table in a bare state. However, this direct placement method is likely to cause the laryngeal mask to fall and be damaged due to accidental contact by medical staff, which is inconvenient for medical staff to assist in examining the patient's stomach later and inconvenient for the stable examination of the gastroscope laryngeal mask later.

[0007] To achieve the above object, the present utility model provides the following technical solution: A disposable protective cover for a gastroscope laryngeal mask, including a positioning tube, the bottom of which is hermetically and penetratingly connected to a mounting seat, and the inside of the mounting seat is hermetically and penetratingly connected to an external connecting tube;

[0008] It further includes: a laryngeal mask body, the bottom of which is provided with a groove and hermetically and penetratingly connected to an air inlet and outlet pipe, and the bottom of the air inlet and outlet pipe is hermetically and penetratingly connected to a hand-held airbag. Moreover, a buffer airbag is arranged on the outer side of the laryngeal mask body, and the buffer airbag is hermetically and penetratingly connected to the air inlet and outlet pipe. The laryngeal mask body is nested and connected with a protective cover body on its outer side, and the protective cover body is in an arc shape and is made of plastic.

[0009] Preferably, a restraint rope is slidably connected through a groove inside the laryngeal mask body, and both ends of the restraint rope penetrate and extend to both ends of the bottom of the laryngeal mask body. The protective cover body can be contracted and positioned through the restraint rope, and the laryngeal mask body can be prevented from loosening and falling off through the restraint rope.

[0010] Preferably, a threaded groove is opened on the inner side of the bottom of the laryngeal mask body, and the positioning tube is threadedly penetrated and connected inside the threaded groove, so that the laryngeal mask body and the positioning tube can be quickly disassembled and replaced.

[0011] Preferably, positioning clamping plates are arranged at both ends inside the mounting seat, and the two positioning clamping plates are in a semi-circular shape. Moreover, an external connecting tube corresponds to the inner sides of the two positioning clamping plates. Anti-slip pads are arranged on the inner sides of the two positioning clamping plates, and the inner sides of the two anti-slip pads are attached to the outer side wall of the external connecting tube. The friction between the mounting seat and the connecting tube can be increased through the two anti-slip pads, and the loosening and falling off of the connecting tube due to the dragging force during use can be avoided later.

[0012] Preferably, the mounting seat has grooves at both inner ends thereof, and pressing rods are slidably connected through the grooves. On the outer sides of the two pressing rods, transmission gears are connected through racks in a meshing manner. On the outer sides of the two transmission gears, limiting rods are connected through racks in a meshing manner. The two limiting rods are slidably installed through the inner ends of the mounting seat. At the same time, positioning clamping plates are connected to the inner ends of the two limiting rods through screws. When pressing the two pressing rods to contract and move, the positioning clamping plates connected to the inner ends of the two limiting rods can be driven to move in position, so that the mounting seat and the connecting pipe can be quickly disassembled, assembled and replaced.

[0013] Preferably, torsion springs are arranged in grooves inside the two transmission gears. The inner ends of the two torsion springs are both connected to the inner side of the mounting seat. The two transmission gears are symmetrically arranged about the vertical center line of the mounting seat. The elastic reset of the positions of the two torsion springs after rotation can be facilitated through the elastic force of the two torsion springs themselves, so that the later repeated use can be facilitated.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By nesting a protective sleeve body in an arc shape outside the laryngeal mask body, the laryngeal mask body exposed to the outside can be buffered and protected against collision by the protective sleeve body, avoiding the phenomenon that the protective sleeve body falls due to accidental collision by medical staff, improving the service life of the laryngeal mask body, and having better practicability;

[0016] Further, a binding rope is slidably installed through a groove inside the protective sleeve body, and then both ends of the binding rope penetrate and extend out of both sides of the bottom of the protective sleeve body. After the protective sleeve body nests and protects the laryngeal mask body, the two ends of the binding rope can be manually pulled to contract and pull, and at this time, the protective sleeve body can be contracted and tightened to avoid the phenomenon that the laryngeal mask body loosens and falls off inside the protective sleeve body;

[0017] Furthermore, a threaded groove is opened inside the bottom of the laryngeal mask body, and a positioning pipe is threadedly connected through the threaded groove inside the threaded groove. When the positioning pipe and the laryngeal mask body need to be quickly disassembled, assembled and replaced in the later stage, the laryngeal mask body and the positioning pipe can be manually rotated to be separated, and then the laryngeal mask body can be quickly disassembled, assembled and replaced, which is more time-saving and labor-saving;

[0018] By slidably installing limiting rods through grooves at both inner ends of the mounting seat, positioning clamping plates are installed by screws at the inner ends of the two limiting rods, and anti-slip pads are attached to the inner ends of the two positioning clamping plates and attached to the outer side wall of the external connecting pipe, the friction between the positioning pipe and the connecting pipe can be increased through the anti-slip pads, avoiding the phenomenon that the positioning pipe loosens and falls off due to the use and dragging of medical staff in the later stage, and improving the use stability of the laryngeal mask body;

[0019] Furthermore, press rods are slidably installed through slots at both inner ends of the mounting base. Then, transmission gears are meshed and connected to the inner ends of the two press rods through racks, and limit rods are meshed and connected to the outer sides of the two transmission gears through racks. When the two press rods are pressed to contract and move, the two limit rods can be driven to move in position. At this time, the two positioning clamping plates can be driven to separate from the connecting pipe, and then the positioning pipe can be quickly disassembled, replaced, and finally, the elastic reset of the positions of the two transmission gears after rotation can be achieved by the elastic force of the two torsion springs, so as to facilitate repeated use in the later stage.
