Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an oxygen mask. Background Art

[0002] After the operation, the patient's vital signs need to be observed in the recovery room. After a certain period of time when spontaneous breathing is restored and there are no abnormalities in vital signs, the patient will be sent back to the ward. Shortly after spontaneous breathing is restored, depending on the patient's physical condition, patients with poor spontaneous breathing ability may need to use an oxygen mask to provide oxygen.

[0003] In the prior art, the end of the oxygen mask does not match the opening size of the universal threaded tube (it is smaller than the threaded tube opening). Anesthesiologists usually use tape to block the gap between the two, but there is still a risk of falling off, affecting the patient's oxygen supply.

[0004] Therefore, it is necessary to provide an oxygen mask to solve the problem of size mismatch between the air inlet pipe of the existing oxygen mask and the oxygen supply pipe at the oxygen supply device end, so as to provide good air tightness for oxygen delivery. Utility Model Content

[0008] Furthermore, the deformable bag includes an air bag, wherein an air tube for inflation / deflation is provided on the air bag, so that the air bag can abut against the inner wall of the oxygen supply tube when inflated.

[0009] Furthermore, a limiting protrusion is provided on the circumference of the outer wall of the oxygen absorption tube; wherein, the length of the limiting protrusion is greater than or equal to the radius difference between the oxygen absorption tube and the oxygen supply tube; the limiting protrusion is made of flexible material, so that the limiting protrusion can abut against the side wall of the oxygen supply tube after the oxygen absorption tube is inserted into the oxygen supply tube; the limiting protrusion is located upstream of the oxygen flow in the oxygen supply tube relative to the airbag.

[0010] Furthermore, the limiting protrusion is bent; wherein the end of the limiting protrusion is bent in the opposite direction to the insertion direction of the oxygen absorption tube.

[0011] Furthermore, a rubber ring for sealing is provided near the end of the oxygen absorption tube to form a closed space between the oxygen absorption tube and the oxygen supply tube; wherein the rubber ring is provided upstream of the oxygen flow in the oxygen supply tube relative to the airbag.

[0012] Furthermore, a ring body is provided near the end of the oxygen absorption tube; the ring width of the ring body is equal to the radius difference between the oxygen absorption tube and the oxygen supply tube; a through hole is opened on the ring body; wherein the airbag and the through hole are connected through a ventilation tube, so that the airbag can be inflated by the oxygen flow in the oxygen supply tube.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0027] like Figure 1-2 As shown, the utility model provides an oxygen mask, comprising:

[0028] The cover body 1 is provided with an oxygen inhalation port 11, and the oxygen inhalation port 11 is connected with an oxygen inhalation tube 12;

[0029] One end of the oxygen absorption tube 12 is connected to the oxygen supply tube 13 to form an oxygen delivery channel;

[0030] Among them, the diameter of the oxygen absorption tube 12 is smaller than that of the oxygen supply tube 13 so that the end of the oxygen absorption tube 12 can be inserted into the oxygen supply tube 13; a deformation bag 2 is provided on the oxygen absorption tube 12 near its end; the deformation bag 2 is arranged around the outer wall of the oxygen absorption tube 12 to form a deformation part in the circumferential direction of the outer wall of the oxygen absorption tube 12.

[0031] The utility model aims to provide a deformable bag 2 on the oxygen inhalation tube 12, and utilize the deformation of the deformable bag 2 itself to ensure that the oxygen inhalation tube 12 can be firmly connected to the oxygen supply tube 13 when inserted, so as to avoid the problem that the oxygen inhalation tube 12 is disengaged from the oxygen supply tube 13 due to the change of air pressure when oxygen is introduced into the pipeline, thereby providing guarantee for the patient to inhale a stable oxygen flow. Specifically, during actual use of the oxygen mask provided by the utility model, the deformable bag 2 can be set to any kind of flexible bag, such as a rubber bag, a foam bag, an elastic plastic bag, etc., so as to ensure that it can produce adaptive deformation after being inserted into the oxygen supply tube 13. It should be noted that the thickness of the deformable bag 2 should be greater than the ring spacing between the oxygen inhalation tube 12 and the oxygen supply tube 13, so that the deformable bag 2 can produce elastic deformation after the oxygen inhalation tube 12 is inserted into the oxygen supply tube 13, so that the deformable bag 2 can be against the inner wall of the oxygen supply tube 13, so that the position of the oxygen inhalation tube 12 is relatively fixed, thereby reducing the leakage of the oxygen flow introduced from the oxygen supply tube 13 to the oxygen inhalation tube 12, thereby improving the patient's oxygen inhalation efficiency and oxygen purity.

[0032] In order to clearly illustrate the operation of the deformation capsule 2 in the present invention, a specific embodiment of the deformation capsule 2 is provided below.

[0033] like Figure 3 As shown, the deformation bag 2 includes an air bag 21;

[0034] The air bag 21 is provided with an air pipe 22 for inflation / deflation, so that the air bag 21 can abut against the inner wall of the oxygen supply tube 13 when inflated.

[0035] In this embodiment, the deformable bag 2 is configured as an air bag 21 that can be actively inflated and deflated, so that after the oxygen tube 12 is inserted into the oxygen supply tube 13, the inflated air bag 21 can be used to fix the oxygen tube 12, thereby maintaining the stability of the oxygen supply and preventing the end of the oxygen tube 12 from coming out due to changes in the air pressure in the pipeline, thereby affecting the patient's normal oxygen therapy.

[0036] In the above embodiment, when the airbag 21 is in the deflated state, the oxygen absorption tube 12 cannot immediately inflate the airbag 21 after being inserted into the oxygen supply tube 13 to support the two, which causes inconvenience in use.

[0037] To solve the above problems, please continue to refer to Figure 3 As shown, in the preferred embodiment provided by the utility model based on the above-mentioned embodiment, a limiting protrusion 121 is provided on the circumference of the outer wall of the oxygen absorption tube 12;

[0038] Among them, the length of the limiting protrusion 121 is greater than or equal to the radius difference between the oxygen absorption tube 12 and the oxygen supply tube 13; the limiting protrusion 121 is made of flexible material, so that the limiting protrusion 121 can abut against the side wall of the oxygen supply tube 13 after the oxygen absorption tube 12 is inserted into the oxygen supply tube 13; the limiting protrusion 121 is located upstream of the oxygen flow in the oxygen supply tube 13 relative to the airbag 21.

[0039] More specifically, in order to facilitate the insertion of the limiting protrusion 121, as Figure 4 As shown, in the preferred embodiment provided by the utility model based on the above embodiment, the limiting protrusion 121 is bent;

[0040] The end of the limiting protrusion 121 is bent in the opposite direction to the insertion direction of the oxygen absorption tube 12 .

[0041] In this embodiment, a limiting protrusion 121 is provided on the oxygen tube 12, so that the oxygen tube 12 can be pre-fixed by utilizing the elastic deformation of the limiting protrusion 121 after being inserted into the oxygen supply tube 13, thereby preventing the oxygen tube 12 from slipping out of the oxygen supply tube 13 again before the airbag 21 reaches a full state during inflation. Furthermore, the bent limiting protrusion 121 can guide the oxygen tube 13 in the process of entering the oxygen supply tube 13, so that the limiting protrusion 121 can enter the oxygen supply tube 13 more easily, thereby preventing the limiting protrusion 121 from conflicting with the side wall of the oxygen supply tube 13, making it difficult for the oxygen tube 12 to enter the oxygen supply tube 13, and affecting the normal use of the mask.

[0042] In the above embodiment, the connection between the oxygen inhalation tube 12 and the oxygen supply tube 13 is sealed only by the filling effect of the airbag 21 on the oxygen supply tube 13 in the inflated state, which may result in poor airtightness due to insufficient inflation pressure of the airbag 21.

[0043] In order to solve the above problems, Figure 6 As shown, in the preferred embodiment provided by the utility model based on the above embodiment, a rubber ring 14 for sealing is provided near the end of the oxygen absorption tube 12, so that a closed space is formed between the oxygen absorption tube 12 and the oxygen supply tube 13;

[0044] The rubber ring 14 is arranged upstream of the oxygen flow in the oxygen supply tube 13 relative to the air bag 21 .

[0045] In this embodiment, by providing the rubber ring 14, the oxygen inhalation tube 12 forms a double seal after entering the oxygen supply tube 13, thereby avoiding the problem of poor airtightness caused by insufficient inflation pressure of the airbag 21, thereby ensuring that the patient inhales a stable oxygen flow.

[0046] In order to realize automatic inflation and deflation of the airbag 21, Figure 7-8 As shown, in the preferred embodiment provided by the utility model based on the above-mentioned embodiment, a ring body 15 is provided near the end of the oxygen absorption tube 12;

[0047] The width of the ring body 15 is equal to the radius difference between the oxygen absorption tube 12 and the oxygen supply tube 13; a through hole 151 is formed on the ring body 15;

[0048] The airbag 21 and the through hole 151 are connected via the ventilation tube 16 , so that the airbag 21 can be inflated by the oxygen flow in the oxygen supply tube 13 .

[0049] In this embodiment, a communicating ventilation tube 16 is provided between the airbag 21 and the ring body 15, so that the airbag 21 can be inflated by utilizing the oxygen flow in the oxygen supply tube 13, and the inflation process is carried out synchronously with the oxygen supply, thereby avoiding the problem of untimely inflation of the airbag 21 and improving the use efficiency of the mask.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
