Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to an anesthesia mask. Background Art

[0002] Anesthesia mask is a common medical device. It is mainly used during anesthesia treatment for patients. It is connected to a ventilator to allow patients to inhale anesthetic gas to reduce the pain of patients during surgery. Most existing anesthesia masks are inflatable masks, which can meet the needs of most patients. However, some patients who have undergone abdominal surgery have gastric tubes in place. During the anesthesia induction process, the periphery of the conventional anesthesia mask cannot fit completely with the patient's face due to the presence of the gastric tube, resulting in a gap between the anesthesia mask and the patient's face. During ventilation, air leakage will occur, which greatly reduces the effectiveness of its use.

[0028] The technical solutions in the embodiments of the utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Those skilled in the art can easily understand other advantages and functions of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Figure 1 —2 shows the main technical content of this embodiment. This specific embodiment provides an anesthesia mask, which includes: a mask body 1;

[0030] A flexible pad 11 is formed along the edge of the mask body 1 to form a closed pattern, wherein the flexible pad 11 is formed with a groove 12 toward the mask body 1;

[0031] The closing member 121 is disposed on the inner wall of the groove 12 , wherein the closing member 121 is disposed along the edge of the groove 12 .

[0032] When in use, the mask body 1 is buckled onto the patient's face. The setting of the flexible pad 11 makes the edge of the mask body 1 fit the curve of the patient's face more closely. Then, the gastric tube worn by the patient is placed in the groove 12, and the gap between the inner wall of the groove 12 and the gastric tube is filled by the sealing member 121, thereby avoiding air leakage during oxygen administration.

[0033] refer to Figure 1 In this embodiment, the flexible pad 11 is constructed as a first airbag, and the width of the flexible pad 11 is greater than the thickness of the mask body 1; after the mask body 1 is buckled onto the patient's face, the first airbag is deformed to fit the patient's facial curve; or, the flexible pad 11 is made of one of silicone and rubber; wherein the cross-section of the flexible pad 11 is elliptical, and when in use, the flexible pad 11 can fit the patient's facial curve, reduce the pressure on the patient's face, and thereby reduce the chance of pressure sores to a certain extent.

[0034] refer to Figure 1In the present embodiment, the groove 12 is an arc-shaped groove having an arc-shaped inner wall, so that after the gastric tube retained by the patient is placed in the groove 12, the arc-shaped inner wall can fit with the outer wall of the gastric tube, thereby reducing the occurrence of air leakage. More specifically, the extending direction of the sealing member 121 is the same as the direction of the inner wall of the groove 12, thereby further reducing the gap between the groove 12 and the gastric tube of the patient, thereby achieving the effect of completely sealing the groove 12 after the gastric tube is placed in the groove 12.

[0035] refer to Figure 1 —2. In the present embodiment, the closing piece 121 is arranged on the inner wall of the groove 12 by bonding or integral connection; preferably, the closing piece 121 and the inner wall of the groove 12 are integrally connected.

[0036] refer to Figure 1 —3 and Figure 6 In this embodiment, the sealing member 121 includes: a balloon, wherein the balloon contains a gas / liquid medium, and the gas / liquid medium does not fill the balloon; when in use, after the gastric tube is placed in the groove 12, the balloon is squeezed and compressed, and then the gap between the inner wall of the groove 12 and the outer wall of the gastric tube is filled, so as to avoid the formation of a gap between the mask body 1 and the patient's face, so as to ensure that there is no air leakage during the ventilation process of the mask body 1.

[0037] In this setting, as an alternative, the groove 12 can be a rectangular groove; its bag body is arranged along the edge of the rectangular groove. After the gastric tube is placed in the groove 12, the bag body is squeezed and deformed, and then wraps the gastric tube, thereby preventing the mask body 1 from leaking during ventilation.

[0038] More preferably, the balloon body is constructed as a second airbag, wherein the second airbag is integrally connected to the inner wall of the groove 12, more specifically, the second airbag contains pre-filled air or inert gas, and the second airbag can be deformed after the outer wall of the second airbag is squeezed by the gastric tube, wherein the second airbag can be made of one of nylon, latex, silicone, PET, and POC materials.

[0039] As an alternative (not shown), the sealing member 121 can also be set as a rubber segment or a silicone segment, wherein the cross-section of the rubber segment or the silicone segment is circular. When in use, after the mask body 1 is fitted to the patient's face, the gastric tube is located in the groove 12, and at this time, the rubber segment or the silicone segment always maintains a tight fit with the outer wall of the gastric tube, thereby playing the role of sealing the mask body 1.

[0040] refer to Figure 2—3. In the present embodiment, the mask body 1 further has a ventilation interface 13, through which the mask body 1 can be connected to an external oxygen source or an anesthetic gas delivery pipeline; when in use, the oxygen source or the anesthetic gas delivery pipeline is pre-connected through the ventilation interface 13, and then the mask body 1 is buckled on the patient's face, and the gastric tube is placed in the groove 12; thereby oxygen supply or anesthesia operation is performed on the patient; more specifically, the ventilation interface 13 has a cylindrical extension section, through which the external oxygen source or the anesthetic gas delivery pipeline is realized.

[0041] refer to Figure 2 —5. In the present embodiment, the extension section is further provided with a fixing ring 14, wherein the fixing ring 14 can be externally connected to at least two straps 143, so that the mask body 1 can be fixed on the patient's face; more specifically, the fixing ring 14 has a pair of first connection points 141 and a pair of second connection points 142, wherein the pair of first connection points 141 are mirror images of each other, and the pair of second connection points 142 are also mirror images of each other; when in use, the two ends of the strap 143 are respectively connected to the two first connection points 141, and similarly, another strap 143 is used to connect its two ends to the two second connection points 142, and then the mask body 1 is buckled onto the patient's face, and the two straps 143 are wrapped around the outside of the patient's head, so as to achieve the wearing of the mask body 1.

[0042] The use of the utility model:

[0043] 1. First, connect two straps to the outside of the fixing ring and place the patient's head between the mask body and the straps so that the mask body always fits the patient's face;

[0044] 2. Place the gastric tube indwelling the patient in the groove. At this time, the sealing piece is squeezed and deformed, thereby filling the gap between the outer wall of the gastric tube and the inner wall of the groove; thereby avoiding air leakage in the mask body during ventilation and oxygen supply.

[0045] 3. Connect an external oxygen source or anesthesia gas delivery pipeline through the ventilation interface to supply oxygen or perform anesthesia on the patient.

[0046] The above-mentioned embodiments are only used to understand the present invention. It should be noted that, for those skilled in the art, several improvements can be made to the present invention without departing from the principle of the present invention, and these improvements will also fall within the scope of protection of the claims of the present invention.
