Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a breathing mask for anesthesia. Background Technology

[0002] Anesthesia is a series of methods used during surgery or diagnostic procedures to eliminate pain, ensure patient safety, and create favorable surgical conditions. During surgery or diagnostic procedures, patients experience pain and may also experience anxiety and adverse reflex reactions such as nausea and vomiting. Therefore, anesthesia is necessary to ensure the patient can undergo the procedure or examination in a comfortable and quiet environment, unresponsive to adverse stimuli, thus guaranteeing the smooth progress of the surgery or examination. Anesthesia masks are commonly used medical devices during anesthesia to provide anesthetic gases and oxygen to the patient.

[0003] However, in current breathing masks, the air inlet tube is usually fixed to the mask. During surgery, the patient's head may move, causing the mask to drag along the tube and potentially causing the mask to tilt and create gaps between it and the patient's face. This can lead to leakage of anesthetic gas or oxygen and cause considerable inconvenience. Therefore, the applicant proposes a breathing mask for anesthesia to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a breathing mask for anesthesia that can effectively reduce the dragging of the air intake tube by the mask when the patient's head shakes, and can prevent the mask from tilting and creating gaps between it and the patient's face, thereby reducing the leakage of anesthetic gas or oxygen.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anesthesia breathing mask, comprising:

[0007] A mask assembly and a fixing assembly mounted on the mask assembly, and an air intake assembly mounted on one side of the mask assembly;

[0008] The mask assembly includes a mask body, a silicone sleeve is snapped into the inner wall of the mask body, and a movable opening is provided on one side of the mask body, with a rubber curtain connected inside the movable opening.

[0009] The air intake assembly includes an air intake pipe rotatably mounted on one side of the rubber curtain, and a plurality of buffer springs are connected between the air intake pipe and the mask body, the plurality of buffer springs being distributed in a ring array.

[0010] Preferably, the fixing component includes a first elastic strap connected to both sides of the mask body, and a second elastic strap connected between the first elastic strap and the top of the mask body.

[0011] Preferably, an auxiliary elastic strap connects the second elastic strap to the first elastic strap, and the auxiliary elastic strap is located on both sides of the second elastic strap.

[0012] Preferably, the two sides of the mask body are connected to the first elastic strap by a first fixing ring, and the top of the mask body is connected to the second elastic strap by a second fixing ring.

[0013] Preferably, the mask body and the silicone sleeve are fixed together by a protruding post, and the mask body is provided with a limiting hole for the protruding post to engage.

[0014] Preferably, the rubber curtain and the air intake pipe are rotatably installed via a rotating shaft sleeve, and the bottom of the air intake pipe is connected to a connecting interface.

[0015] Preferably, one end of the buffer spring is connected to the air intake pipe via a fixing sleeve, the fixing sleeve and the air intake pipe are rotatably mounted, and the other end of the buffer spring is fixedly connected to the mask body via a fixing block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The present invention has a rubber curtain between the mask body and the air inlet tube. The softness of the rubber curtain allows the air inlet tube and the mask body to float in multiple directions. When the mask body moves with the patient's head, it can effectively reduce the drag on the air inlet tube and prevent the mask body from being dragged and causing the patient's face to tilt and create gaps. This makes it less likely for anesthetic gas or oxygen to leak. At the same time, the air inlet tube can be rotated to a suitable angle according to the arrangement of the tubes, so as not to affect the operation during surgery and treatment and improve the effect of use.

[0018] (2) The present invention has a buffer spring between the air intake pipe and the mask body. The buffer spring can provide buffer support for the air intake pipe through its elastic action, so that the air intake pipe can be buffered when subjected to drag force, and can be quickly reset after the drag force is released.

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an anesthesia breathing mask includes:

[0030] The mask assembly 2 and the fixing assembly 1 mounted on the mask assembly 2, and the air intake assembly 3 mounted on one side of the mask assembly 2;

[0031] The mask assembly 2 includes a mask body 21, a silicone sleeve 23 is snapped into the inner wall of the mask body 21, and an opening 27 is provided on one side of the mask body 21. A rubber curtain 28 is connected inside the opening 27.

[0032] The air intake assembly 3 includes an air intake pipe 31 rotatably mounted on one side of the rubber curtain 28. Several buffer springs 34 are connected between the air intake pipe 31 and the mask body 21. The several buffer springs 34 are arranged in a ring array.

[0033] As can be seen from the above, by using the fixing component 1 to fix the mask body 21 to the patient's face during use, the mask body 21 can cover the patient's mouth and nose. The silicone sleeve 23 can fit the facial skin, which can improve the sealing between the mask body 21 and the face. At the same time, the silicone sleeve 23 is detachable, so after one patient uses it, the silicone sleeve 23 can be replaced for the next patient to use. There is no need to replace the entire mask body 21, so the mask body 21 can be recycled, which effectively reduces the waste of resources.

[0034] By connecting the air inlet tube 31 to the gas supply equipment, anesthetic gas can be delivered into the mask body 21, facilitating anesthesia for patients. It can also be connected to the oxygen supply equipment for convenient oxygen delivery to patients. During the patient's surgery, the flexible rubber curtain 28 allows the air inlet tube 31 to float in multiple directions at the movable opening 27. This effectively reduces the drag on the air inlet tube 31 when the mask body 21 moves with the patient's head, preventing the mask body 21 from being pulled and causing it to tilt and create gaps with the patient's face. This also prevents leakage of anesthetic gas or oxygen. In addition, the air inlet tube 31 can be rotated to a suitable angle according to the arrangement of the tubing, avoiding interference with the operation during surgery and treatment, thus improving the effectiveness of use.

[0035] When displacement occurs between the mask body 21 and the air intake pipe 31, the elasticity of the buffer spring 34 can provide buffer support for the air intake pipe 31, so that the air intake pipe 31 can be buffered when subjected to dragging force. At the same time, the air intake pipe 31 can be quickly reset after the dragging force is released, which brings more convenience to the user.

[0036] Depend on Figure 1 and Figure 3 It is known that the fixing component 1 includes a first elastic strap 11 connected to both sides of the mask body 21, and a second elastic strap 12 connected between the first elastic strap 11 and the top of the mask body 21.

[0037] As can be seen from the above, the first elastic strap 11 can wrap around the patient's head, and the second elastic strap 12 can limit the position of the top of the patient's head, which makes it convenient to fix the mask body 21.

[0038] For details, please refer to Figure 3 As shown, an auxiliary elastic strap 13 is connected between the second elastic strap 12 and the first elastic strap 11, and the auxiliary elastic strap 13 is located on both sides of the second elastic strap 12.

[0039] As can be seen from the above, the auxiliary elastic bandage 13 can increase the force range of the second elastic bandage 12, and at the same time limit the second elastic bandage 12, so that the second elastic bandage 12 is not easy to become crooked and avoid falling off the patient's head.

[0040] For details, please refer to Figure 2 , Figure 3 and Figure 4 As shown, the two sides of the mask body 21 are connected to the first elastic strap 11 by the first fixing ring 25, and the top of the mask body 21 is connected to the second elastic strap 12 by the second fixing ring 26.

[0041] As can be seen from the above, the first fixing ring 25 can connect and fix both ends of the first elastic band 11, so that when the first elastic band 11 is put on the patient's head, it can apply a pulling force to both sides of the mask body 21 and limit the mask body 21. The second fixing ring 26 can connect and fix one end of the second elastic band 12, so that when the second elastic band 12 is put on the top of the patient's head, it can apply a pulling force to the top of the mask body 21 and form a triangular fixing effect with the first elastic band 11, which effectively improves the fixing effect of the mask body 21 and reduces the occurrence of falling off.

[0042] Example 2:

[0043] refer to Figure 4 As shown, the mask body 21 and the silicone sleeve 23 are fixed together by a protrusion 24, and the mask body 21 is provided with a limiting hole 22 for the protrusion 24 to be engaged.

[0044] As can be seen from the above, by inserting the protruding post 24 into the limiting hole 22, the silicone sleeve 23 can be easily installed and disassembled, making it convenient to replace it according to usage requirements.

[0045] refer to Figure 5 As shown, the rubber curtain 28 and the air intake pipe 31 are rotatably installed through the rotating shaft sleeve 29, and the bottom of the air intake pipe 31 is connected to the interface 32.

[0046] As can be seen from the above, the air inlet pipe 31 can be rotated by the rotating sleeve 29, so that the air inlet pipe 31 can be rotated to a suitable angle according to the arrangement of the air supply pipeline, avoiding large bending of the air supply pipeline. The air inlet pipe 31 can be connected to the air supply pipeline through the interface 32, which facilitates the operation of supplying air to the patient.

[0047] refer to Figure 5 As shown, one end of the buffer spring 34 is connected to the air intake pipe 31 through a fixing sleeve 33, and the fixing sleeve 33 and the air intake pipe 31 are rotatably installed. The other end of the buffer spring 34 is fixedly connected to the mask body 21 through a fixing block 35.

[0048] As can be seen from the above, the buffer spring 34 can be easily fixed by the fixing sleeve 33 and the fixing block 35, so that the buffer spring 34 can support the air intake pipe 31. At the same time, the fixing sleeve 33 can rotate around the air intake pipe 31 without affecting the rotation operation of the air intake pipe 31.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
