Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to a pediatric anesthesia mask fixation device. Background Technology
[0002] During pediatric surgery, anesthesia is required. During anesthesia, a breathing mask is placed against the child's face to facilitate the inhalation of anesthetic gas. The breathing mask needs to be fixed to the child's head with a fixing device to prevent the mask from falling off due to the child's head shaking due to tension.
[0003] The prior art document CN219110524U provides a laryngeal mask airway fixator for pediatric ophthalmic surgery anesthesia, which includes: a main body cuff, a one-way inflation valve for the main body cuff, a main body, a strap connector, a laryngeal mask fastening element, and fastening bolts; the main body and the main body cuff are seamlessly connected, and the main body cuff is inflated and deflated by the main body cuff one-way inflation valve to adjust its fit to the face; the strap is connected to the main body through the strap connector; the laryngeal mask fastening element is provided with fastening bolts, and the size of the opening of the fastening element can be adjusted by rotating the fastening bolts, and its maximum opening can allow the ventilation tube of the largest laryngeal mask to pass through; the laryngeal mask fastening element is located directly above the main body of the fixator.
[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:
[0005] The mask is connected by only two strap connectors. The two straps are tightly wrapped around the child's head. The tightening area is small, and the mask can only be tightened in one direction. When the child's head moves, the mask is prone to tilting, which is not conducive to the mask fitting the child's face tightly, thus causing leakage of anesthetic gas.
[0006] Regarding the aforementioned related technologies, the inventor believes that simply connecting the straps with two strap connectors and binding them tightly around the child's head results in a small tightening area. This means the mask can only be tightened in one direction, which can easily cause the mask to tilt when the child's head moves. This makes it difficult for the mask to fit snugly against the child's face, potentially leading to leakage of anesthetic gas.
[0007] In view of this, we propose a pediatric anesthesia mask fixation device. Utility Model Content
[0008] 1. Technical problems to be solved
[0009] The purpose of this application is to provide a pediatric anesthesia mask fixation device, which solves the technical problems in the above-mentioned prior art where only two strap connectors are used to connect the straps, the two straps are wrapped tightly around the child's head, the tensioning area is small, the mask can only be tightened in one direction, and when the child's head shakes, the mask is prone to tilting, which is not conducive to the mask fitting the child's face tightly, thus leading to leakage of anesthetic gas. The application achieves the desired technical effect.
[0010] 2. Technical Solution
[0011] This application provides a pediatric anesthesia mask fixation device, comprising:
[0012] Mask body;
[0013] A connecting tube is fixedly sleeved on the mask body;
[0014] A breathing tube, on which the connecting tube is movably sleeved;
[0015] A limiting mechanism is installed on the outer wall of the connecting pipe;
[0016] The strap is movably connected to the limiting mechanism.
[0017] The above method connects the breathing tube to the anesthetic gas source and uses a limiting mechanism to lock the connecting tube in place. After the mask is fitted to the child's face, the straps tighten the child's head in multiple directions, providing multi-directional tension. Combined with the limiting mechanism's restraint of the mask, it prevents the mask from tilting, thus ensuring that the mask fits snugly against the child's face and preventing anesthetic gas leakage.
[0018] Optionally, the limiting mechanism includes a convex ring, the bottom of the connecting pipe is integrally formed with a convex ring, a connecting ring is movably sleeved on the convex ring, multiple limiting blocks are fixedly installed on the bottom of the outer wall of the convex ring, multiple limiting grooves are opened on the inner wall of the connecting ring, the limiting grooves are movably engaged with the limiting blocks, multiple insert rods are fixedly installed on the top edge of the connecting ring, and a nut ring is threaded onto the convex ring, and the nut ring presses on the connecting ring.
[0019] With the above solution, the connecting ring is sleeved on the convex ring, and the limiting groove is engaged with the limiting block. The nut ring presses and fixes the connecting ring. Then, multiple insert rods are connected to the straps, thereby limiting the mask body at multiple points and preventing it from tilting.
[0020] Optionally, the strap includes an annular band that is movably fitted onto the outside of the nut ring. The annular band has an insertion hole that is movably fitted onto a plug. Two short connecting bands are fixedly installed on one side of the annular band, and each short connecting band has a locking pin fixedly installed on it. Two long connecting bands are fixedly installed on the other side of the annular band, and each long connecting band has multiple adjustment holes that are movably engaged with the locking pins. The inner diameter of the annular band is equal to the outer diameter of the nut ring. The annular band, short connecting bands, and long connecting bands are all made of elastic rubber. The bottom of the locking pin is a cylindrical structure with a diameter equal to that of the adjustment hole, and the top of the locking pin is a hemispherical structure with a diameter greater than that of the adjustment hole.
[0021] The above solution involves using a ring-shaped strap with a nut ring to engage the insertion hole and insert rod. Multiple long connecting straps are then wrapped around the back of the child's head, and the adjustment hole is engaged with the locking post, thereby tightening the mask body in multiple directions. The engagement of multiple insertion holes and insert rods fully limits the mask body and prevents it from tilting.
[0022] Optionally, multiple O-rings are fixedly embedded in the connecting tube, the inner wall of the breathing tube is tightly fitted with the O-rings, the diameter of the O-rings is smaller than the outer diameter of the convex ring, and a soft pad is fixedly fitted to the bottom of the mask body.
