As shown in fig. 1 and 2, an embodiment of the present invention provides a simple respirator including: a balloon 100, a mask assembly 110, an outlet valve assembly 130, an inlet valve 140, an oxygen reservoir bag 160, and an inlet tube 170. Balloon 100 is used to store oxygen, and balloon 100 includes a first compression portion 101, a second compression portion 102, an air outlet 103, and an air inlet 104, and the area of first compression portion 101 is larger than the area of second compression portion 102.

The air outlet 103 of the balloon 100 is communicated with the mask assembly 110 through an air outlet valve assembly 130, and the air inlet 104 of the balloon is communicated with an oxygen storage bag 160 and an air inlet pipe 170 through an air inlet valve 140 respectively. Vent valve assembly 130 is used to control the flow of air between balloon 100 and mask assembly 110. The oxygen storage bag 160 is used for supplementing oxygen into the balloon 100, and the air inlet pipe 170 is communicated with an oxygen source and used for supplementing oxygen into the oxygen storage bag 160 and the balloon 100. The air inlet valve 140 is used for controlling the on-off of the air flow between the oxygen storage bag 160 and the balloon 100.

When first compression 101 or second compression 102 of balloon 100 is compressed, oxygen stored within balloon 100 flows out of mask assembly 110 through gas outlet valve assembly 130. Since the area of the first compression portion 101 is larger than the area of the second compression portion 102, the amount of deformation of the balloon 100 when the first compression portion 101 is compressed is larger than the amount of deformation of the balloon 100 when the second compression portion 102 is compressed. Thus, when the first squeeze portion 101 is squeezed, the mask assembly 110 will flow a greater amount of oxygen than when the second squeeze portion 102 is squeezed, and the mask assembly 110 will flow a greater amount of oxygen. The airflow volume includes at least one of an airflow flow rate and an airflow volume.

In summary, the balloon 100 is provided with the first pressing portion 101 and the second pressing portion 102, and the area of the first pressing portion 101 is larger than that of the second pressing portion 102; such that when the first squeeze portion 101 is squeezed, the mask assembly 110 will deliver a greater amount of oxygen than when the second squeeze portion 102 is squeezed, and the mask assembly 110 will deliver a greater amount of oxygen; the technical problem of among the prior art simple and easy respirator can't provide different air flow to the disease of different air flow demand is solved, reached and provided the technological effect of different air flow according to different disease demands, improved simple and easy respirator's suitability, need not to set up the simple and easy respirator of multiple model, saved the equipment spending of hospital.

In one embodiment, referring to fig. 3-5 in combination, balloon 100 includes a stent 105, and the stent 105 defines a first through hole (not shown) and a second through hole (not shown), wherein the area of the first through hole is larger than the area of the second through hole. And, the first through-hole is covered with a flexible material to form a first pressing portion 101, and the second through-hole is covered with a flexible material to form a second pressing portion 102. That is, the scaffold 105 of the balloon 100 is made of a hard material that is not easily deformed, such as a hard plastic or the like. A through hole is formed in the stent 105 of the balloon 100, and the inside and the outside of the balloon 100 are communicated through the first through hole and the second through hole. The surfaces of the first through hole and the second through hole can be covered with flexible materials, such as flexible silica gel films and the like, and sealing can be formed on the first through hole and the second through hole. When the balloon 100 is filled with oxygen, the flexible material covering the first through hole and the second through hole swells. At this time, the flexible material covering the first through hole and the second through hole may be pressed, so that the flexible material is pressed into the balloon through the first through hole and the second through hole, thereby pressing out the gas stored in the balloon through the mask assembly 110. Since the stent 105 is made of a material which is not easily deformed, when the first pressing part 101 and the second pressing part 102 are pressed, the stent 105 is not deformed, that is, oxygen in the balloon 100 only flows out from the air outlet 103 of the balloon 100 when the first pressing part 101 and the second pressing part 102 are pressed, so that no deformation of other parts causes extra oxygen to flow out. Therefore, the first squeezing portion 101 can squeeze out a first volume of oxygen gas when squeezed, and the second squeezing portion 102 can squeeze out a second volume of oxygen gas when squeezed, and the first volume is larger than the second volume.

Taking the simple respirator shown in fig. 1 as an example, in fig. 1, the flexible material of the first pressing portion 101 and the second pressing portion 102 filled with oxygen in the balloon 100 is bulged. In the case of the simple respirator shown in fig. 2, the first squeeze portion 101 is in a squeezed state and oxygen flows out of the mask assembly 110.

During actual medical work, when the simple respirator is used for an adult patient, the first pressing part 101 can be pressed to deliver a first volume of oxygen to the adult patient; when the ventilator is to be used with a pediatric patient, the second squeeze 102 may be depressed to deliver a second volume of oxygen to the pediatric patient. In this way, the problem of different oxygen needs of adult and child patients is solved.

In addition, the mask assembly 110 needs to be placed over the face of a patient during use of the compact respirator, and different patients may have different facial sizes, except for the different oxygen requirements. For example, adult patients have faces that are different in size than children. The mask assembly 110, which is not sized properly, may be easily deflated on the patient's face, which may affect the performance of the simple respirator.

In response to the above problems, as shown in fig. 6, in one embodiment, a mask assembly 110 includes: a first cover 111, a second cover 112, and a telescoping member 113. A telescopic piece 113 is arranged between the second cover piece 112 and the first cover piece 111, the first cover piece 111 and the second cover piece 112 are used for covering the face of a patient, and the covering area of the second cover piece 112 is larger than that of the first cover piece 111. As such, when a larger patient needs treatment, the second cover 112 may be used to cover the patient's face; when a smaller patient needs treatment, the first cover 111 may be used to cover the patient's face.

Further, the extensible member 113 has an extended state and a contracted state, and when the extensible member 113 is in the extended state, the second cover 112 covers the face of the patient; when the telescopic member 113 is in the contracted state, the first cover 111 covers the face of the patient.

Referring specifically to fig. 6, the extensible member 113 of the mask assembly 110 of fig. 6 is in a stretched state, and in use, the second cover member 112 may be placed over the patient's face. The health care provider grasps second cover 112 and presses second cover 112 against the patient's face, and then squeezes balloon 100. In fig. 7, the telescopic member 113 is in a contracted state, in which the first cover 111 is located inside the second cover 112, and the first cover 111 can be applied to the patient's face in use. The health care provider grasps the outer surface of the first cover 111, first presses the second cover 112 against the patient's face, and then continues to apply pressure to the first cover 111 so that the first cover 111 continues to move toward the patient's face. In the process, the expansion member 113 begins to contract until the first cover 111 is pressed against the patient's face. The medical staff presses balloon 110 to deliver oxygen while keeping pressure on first cover 111. At this time, the first covering piece 111 always supports the face of the patient under the action of pressure, so as to avoid oxygen leakage; while the second cover 112 is not applying pressure, it may be in contact with the patient's face but does not apply pressure to the patient's face causing discomfort to the patient.

In this embodiment, the first covering part 111 and the second covering part 112 may be made of rigid plastic, and the expansion part 113 may be made of a soft silicone material, such as a silicone film, which deforms and returns to its original shape. As shown in fig. 6 and 7, when the extensible member 113 is not applied with an external force, the silicone film is flattened and covers the patient's face with the second cover member 112 when the extensible member 113 is in a stretched state; when the extensible member 113 is applied with an external force, the silicone film is folded when the extensible member 113 is in a contracted state, and the patient's face is covered with the first cover member 111.

Through setting up first covering 111, second covering 112, being connected and have the connecting piece of tensile and shrink state with first covering 111 and second covering 112 for simple and easy respirator is applicable to the patient of facial size difference, need not to change mask assembly 110, and convenient and fast just can save the cost of equipment.

In one embodiment, referring collectively to fig. 6, mask assembly 110 further includes a connector 114. One end of the connector 114 is fixedly connected to the first cover 111 and is communicated with the first cover 111, and the other end of the connector 114 is communicated with the air outlet valve assembly 130. Oxygen within the balloon 100 flows through the outlet valve assembly 130 and the connector 114 into the mask assembly 110.

In actual use, since the first cover 111 and the second cover 112 need to be covered and pressed on the face of the patient, and the first cover 111 and the second cover 112 are made of hard materials, the long-term pressing is easy to cause pain and discomfort on the face of the patient. To address this issue, in one embodiment, the first cover 111 includes a first inflation 1111 and a first inflation port 1112. The first inflation piece 1111 is disposed on a side of the first covering piece 111 away from the connection head 114. When the first cover 111 is applied to the patient's face, the first inflation member 1111 contacts the patient's face. The first inflation port 1112 is adapted to be connected to an external gas source to inflate the first inflation member 1111.

The second cover 112 includes a second inflation 1121 and a second inflation port 1122. The second inflation piece 1121 is disposed on a side of the second cover piece 112 away from the first cover piece 111, and the second inflation piece 1122 is in contact with the patient's face when the second cover piece 112 is covered on the patient's face. The second inflation port 1122 is used for connecting with an external air source to inflate the second inflatable member 1121.

By arranging the first inflating part 1111 and the second inflating part 1121 on the first covering part 111 and the second covering part 112, the first inflating part 1111 and the second inflating part 1121 are inflated to expand and have certain elasticity, and the contact surface is soft when the first inflating part 1111 and the second inflating part 1121 are pressed against the face of a patient, so that pain or other discomfort cannot be caused to the patient.

Optionally, in one embodiment, referring to fig. 1 in combination, the simple respirator further comprises a pressure relief valve 120, the pressure relief valve 120 being disposed between the gas outlet 103 and the gas outlet valve 130 of the balloon 100. The pressure relief valve 120 is configured to open when the pressure of oxygen flowing from the balloon 100 to the outlet valve assembly 130 is greater than a predetermined threshold, so as to divert a portion of the oxygen to the outside of the ventilator, thereby preventing the oxygen with higher pressure from damaging the airway of the patient.

Optionally, in one embodiment, the outlet valve assembly 130 further comprises a one-way valve 131. The one-way valve 131 communicates between the outlet port 103 and the mask assembly 110 and opens only when oxygen flows from the outlet port 103 to the mask assembly 110. When first compression 101 or second compression 102 of balloon 100 is compressed, oxygen within balloon 100 flows out of gas outlet 103 into one-way valve 131, one-way valve 131 opens, and oxygen flows out of mask assembly 110 through one-way valve 131. When the compressed balloon 100 is restored, the check valve 131 is closed, and external air is prevented from flowing into the balloon 100 through the mask assembly 110.

Further, in one embodiment, the exhalation valve assembly 130 also includes an exhalation valve 132. Exhalation valve 132 communicates between mask assembly 110 and the exterior of the respirators and is only opened when gas enters outlet valve assembly 130 from mask assembly 110. When using the simple respirator, the patient exhales toward the mask assembly 110, and the exhaled air cannot be discharged because the mask assembly 110 is in communication with the one-way valve 131. At this time, the problem of patient exhalation is solved by arranging the exhalation valve 132 so that the gas exhaled by the patient can be exhausted to the outside of the simple respirator through the exhalation valve 132. Moreover, since the exhalation valve 132 is opened only when gas enters the exhalation valve assembly 130 from the mask assembly 110, the gas flowing out of the balloon 100 is prevented from being discharged from the exhalation valve 132, which affects the use effect.

Further, the simple respirator further comprises an air storage valve 150, the air storage valve 150 is arranged between the air inlet valve 140 and the oxygen storage bag 160, and the air storage valve 150 is used for controlling the on-off of oxygen between the air inlet valve 140 and the oxygen storage bag 160.

The simple respirator provided by the application selects to cover the first covering piece 111 or the second covering piece 112 on the face of a patient according to the size of the face of the patient when in use, and selects to press the first pressing part 101 or the second pressing part 102 according to the oxygen demand of the patient. When the first pressing part 101 or the second pressing part 102 is pressed, the check valve 131 is opened, the air inlet valve 140 is closed, and oxygen in the balloon 100 flows into the mask assembly 110 through the air outlet 103, the pressure safety valve 120 and the check valve 131 in sequence. When the pressure is removed, the one-way valve 131 is closed, the air inlet valve 140 is opened, and oxygen in the oxygen storage bag 160 enters the balloon 100 through the air storage valve 150 and the air inlet valve 140, so that the balloon 100 is filled with oxygen. Oxygen supplied from an external oxygen source is supplied into the oxygen storage bag 160 through the intake pipe 170 via the intake valve 140. Alternatively, an external oxygen source may supplement oxygen directly into balloon 100 through inlet valve 140. When the patient exhales, the exhaled gas flows from within mask assembly 110 to the exterior of the simple respirator via exhalation valve 132. This simple and easy respirator can be applicable to the patient of different face sizes, only need through the extensible member 113 switch first covering 111 or second covering 112 can, need not to change the face guard, convenient and fast, and save the equipment cost. The oxygen-enriched air compressor can also be suitable for patients with different oxygen requirements, and only the first pressing part 101 and the second pressing part 102 need to be pressed, so that the oxygen-enriched air compressor is simple and accurate. And the volume of the oxygen flowing out is the same when the first pressing part 101 or the second pressing part 102 is pressed completely each time, so that the difference of the oxygen flowing out at each pressing time caused by the strength of the user or the size of the palm is avoided, and the accuracy of oxygen flowing out is ensured.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
