Description

Technical Field

[0001] The present application relates to the technical field of respirators, and more particularly to a portable respirator. Background Art

[0002] When a patient experiences an emergency such as difficulty breathing, artificial respiration is a necessary rescue measure. The commonly used method now is for medical staff and patients to perform mouth-to-mouth artificial respiration directly. However, during normal rescue, mouth-to-mouth artificial respiration poses a risk of cross-infection, which is detrimental to the health of both medical staff and patients. For this reason, the hospital also provides a portable simple respirator, which is a very common facility in medical treatment to assist patients in breathing. Especially in some emergency situations, the respirator is a life-threatening facility that can quickly provide patients with the necessary respiratory support in emergency scenarios, which is of great significance to protecting patients' lives.

[0003] When using existing portable respirators, their portability leads to a relatively simple design. When treating patients, it is usually impossible to dynamically adjust the oxygen supply pressure according to the patient's hypoxia condition, which may cause the oxygen supply pressure to be too high or too low, thereby affecting the treatment effect. Excessively high oxygen supply pressure may cause oxygen poisoning or respiratory tract damage, while too low oxygen supply pressure may not be able to meet the patient's oxygen needs, resulting in hypoxia. Utility Model Content

[0005] The present application provides a portable respirator that adopts the following technical solutions:

[0006] A portable respirator includes a pressing portion, a top portion of the pressing portion is connected to a delivery tube, a top portion of the delivery tube is connected to an oxygen mask, and an adjustment component is provided inside the delivery tube;

[0007] The adjustment component includes a pressure plate with multiple pressure holes opened inside. The diameters of the pressure holes are different. The inside of the delivery pipe is rotatably connected to the adjustment plate, and the adjustment plate has adjustment holes opened inside. The adjustment plate is located above the pressure plate.

[0008] Through the above technical solution, the regulating component can dynamically adjust the oxygen supply pressure according to the actual situation of the patient, avoiding oxygen poisoning or respiratory tract damage caused by excessively high oxygen supply pressure, and preventing the oxygen supply pressure from being too low to meet the patient's oxygen needs, thereby improving the treatment effect.

[0009] Furthermore, a friction groove is provided at the gap where the delivery pipe and the adjusting disk are rotatably connected, and a sealing ring is provided inside the friction groove. The two sealing rings are respectively located at one end of the adjusting disk and the pressure disk.

[0010] Through the above technical solution, the sealing ring can prevent gas leakage on the one hand, ensuring the stability and safety of oxygen supply; on the other hand, the friction groove can provide a certain friction force, so that the adjustment disk can remain stable after being adjusted to a specific position and will not rotate easily.

[0011] Furthermore, a plurality of grooves are provided on the outer side of the adjusting disk, a plurality of marks are fixedly connected to the outer wall of the delivery pipe, and a pointer is provided at the outer end of the adjusting disk.

[0012] Through the above technical solution, these marks can correspond to different pressure levels, making it convenient for users to accurately adjust the required oxygen supply pressure.

[0013] Furthermore, a connecting tube is provided at the bottom of the pressing portion, a tube body is provided at the bottom of the connecting tube, and a sealing ring is provided between the connecting tube and the tube body.

[0014] Through the above technical solution, the connecting pipe and the pipe body are sealed by the sealing ring to prevent oxygen leakage.

[0015] Furthermore, cavities are provided at both ends of the tube body, and fixing plates are provided inside the two cavities. Elastic blocks are fixedly connected to the opposite ends of the two fixing plates. Card slots are provided at both ends of the connecting tube, and the two elastic blocks are respectively connected to the corresponding card slots.

[0017] Furthermore, an oxygen storage bag is provided at the bottom of the tube body, and one end of the delivery tube is connected to the oxygen inhalation mask via a thread.

[0018] Through the above technical solution, the threaded connection makes it very convenient to disassemble and replace the delivery tube and the oxygen mask.

[0019] Furthermore, a set of straps is provided at both ends of the oxygen mask, and the two sets of straps are symmetrically distributed along the central axis of the oxygen mask.

[0020] Furthermore, the outermost end of each strap is provided with a Velcro.

[0021] Through the above technical solution, the strap can firmly fix the oxygen mask on the patient's face to ensure that the oxygen mask will not fall off accidentally during use. The Velcro design makes it very convenient to fix and adjust the strap, and the user can quickly stick or unstick the Velcro as needed.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] Reference Figure 1-Figure 5 A portable respirator includes a pressing portion 1, a delivery tube 2 is connected to the top of the pressing portion 1, an oxygen mask 3 is connected to the top of the delivery tube 2, and an adjustment component is provided inside the delivery tube 2;

[0034] The adjustment assembly includes a pressure plate 10, which has multiple pressure holes 11 inside. The diameters of the pressure holes 11 are different. The inside of the delivery pipe 2 is rotatably connected to an adjustment plate 7, which has an adjustment hole 9 inside. The adjustment plate 7 is located above the pressure plate 10.

[0035] When using this portable respirator, the user rotates the adjustment dial 7 to align the adjustment hole 9 on the adjustment dial 7 with the pressure holes 11 of different diameters on the pressure plate 10. Since the pressure holes 11 have different diameters, when the adjustment hole 9 is connected to the pressure holes 11 of different diameters, the size of the gas passageway is changed, thereby adjusting the pressure of the oxygen supply. During the rotation of the adjustment dial 7, the pointer on the outside of the adjustment dial 7 will point to different markings 6 on the outer wall of the delivery tube 2. These markings 6 correspond to different pressure levels, allowing the user to accurately adjust the desired oxygen supply pressure.

[0036] By adjusting the settings of the components, the oxygen supply pressure can be dynamically adjusted according to the actual situation of the patient, avoiding oxygen poisoning or respiratory tract damage caused by excessively high oxygen supply pressure, and preventing the oxygen supply pressure from being too low to meet the patient's oxygen needs, thereby improving the treatment effect.

[0037] The overall structure of this application is compact and easy to carry, and is suitable for various occasions requiring emergency oxygen supply.

[0038] Reference Figure 3-Figure 4 A friction groove is provided at the gap where the delivery pipe 2 and the adjusting disk 7 are rotatably connected. A sealing ring 8 is provided on the inner side of the friction groove. The two sealing rings 8 are respectively located at one end of the adjusting disk 7 and the pressure disk 10. A plurality of grooves are provided on the outer side of the adjusting disk 7. A plurality of marks 6 are fixedly connected to the outer wall of the delivery pipe 2, and a pointer is provided on the outer end of the adjusting disk 7.

[0039] A friction groove and a sealing ring 8 are provided at the gap where the delivery pipe 2 and the adjustment disk 7 are rotatably connected. On the one hand, the sealing ring 8 can prevent gas leakage and ensure the stability and safety of oxygen delivery; on the other hand, the friction groove can provide a certain friction force so that the adjustment disk 7 can remain stable after being adjusted to a specific position and will not rotate easily.

[0040] Reference Figure 1-Figure 5The bottom of the pressing part 1 is connected to a connecting tube 12, and a tube body 13 is provided at the bottom of the connecting tube 12. A sealing ring 14 is provided between the connecting tube 12 and the tube body 13. Both ends of the tube body 13 are provided with cavities, and both cavities are provided with fixing plates 15. The opposite ends of the two fixing plates 15 are fixedly connected to elastic blocks 4. Both ends of the connecting tube 12 are provided with card slots, and the two elastic blocks 4 are respectively connected to the corresponding card slots.

[0041] When the portable respirator is used, when the pressing portion 1 is pressed, gas is drawn from the pressing portion 1, extracting oxygen from the oxygen storage bag 5, and passing through the connecting tube 12, the tube body 13, and ultimately delivered to the patient through the oxygen mask 3. The connecting tube 12 and the tube body 13 are sealed by a sealing ring 14 to prevent oxygen leakage. The fixing plates 15 at both ends of the tube body 13 are each provided with a spring (not shown in the figure) on the facing side. When the tube body 13 is inserted into the connecting tube 12, the end of the connecting tube 12 first contacts the elastic block 4. Because the spring is provided between the elastic block 4 and the fixing plate 15, the elastic block 4 compresses the spring and moves toward the fixing plate 15 under the thrust. As the tube body 13 continues to be inserted, when the elastic block 4 reaches the retaining grooves at the ends of the connecting tube 12, the spring force pushes the fixing plate 15, causing the elastic block 4 to snap into the retaining grooves, thus achieving a stable connection between the connecting tube 12 and the tube body 13.

[0042] When disassembling, press the elastic blocks 4 on both sides to disassemble.

[0043] Reference Figure 1-Figure 2 The bottom of the tube body 13 is connected to the oxygen storage bag 5, and one end of the delivery tube 2 is connected to the oxygen inhalation mask 3 through a thread.

[0044] The threaded connection makes it very convenient to disassemble and replace the delivery tube 2 and the oxygen mask 3. When the oxygen mask 3 needs to be replaced or the delivery tube 2 needs to be cleaned or disinfected, the two can be easily separated.

[0045] Reference Figure 1-Figure 2 A set of straps 16 are provided at both ends of the oxygen mask 3. The two sets of straps 16 are symmetrically distributed along the central axis of the oxygen mask 3. The outermost end of each strap 16 is provided with a Velcro 17.

[0046] The strap 16 can firmly fix the oxygen mask 3 on the patient's face to ensure that the oxygen mask 3 will not fall off accidentally during use. Regardless of whether the patient is moving, turning over or in an unconscious state, the strap 16 can effectively keep the mask in a stable position to ensure a continuous supply of oxygen.

[0047] The design of the magic tape 17 makes it very convenient to fix and adjust the strap 16. The user can quickly stick or undo the magic tape 17 as needed.

[0048] Working principle: When in use, fix the oxygen mask 3 to the patient's face with the straps 16 and Velcro 17. Then, carefully turn the adjustment dial 7 according to the patient's specific situation, such as the degree of hypoxia, the severity of the disease and the patient's physical condition. During the rotation, observe the correspondence between the pointer on the outside of the adjustment dial 7 and the mark 6 on the outer wall of the delivery tube 2 to ensure that the adjustment hole 9 is accurately aligned with the pressure hole 11 of the appropriate diameter on the pressure plate 10, so as to achieve precise adjustment of the oxygen supply pressure. This process requires medical staff to make judgments based on their professional knowledge and experience, so as to achieve the purpose of meeting the patient's oxygen needs while avoiding oxygen poisoning or respiratory damage due to excessive pressure.

[0049] Afterwards, the pressing part 1 is pressed moderately. At this time, the oxygen in the oxygen storage bag 5 passes through the connecting tube 12 and the tube body 13 in sequence under the action of pressure. In this process, it is necessary to ensure that the connecting tube 12 and the tube body 13 are firmly connected, and the sealing ring 14 plays a good sealing role to prevent oxygen leakage. After passing through the tube body 13, the oxygen enters the regulating component of the delivery tube 2. The regulating component finely adjusts the oxygen according to the set pressure parameters. Finally, the regulated oxygen is stably output from the oxygen mask 3 at one end of the delivery tube 2 and delivered to the patient, providing the patient with timely and effective oxygen treatment.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
