Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a medical oxygen regulating valve. Background Technology

[0002] In today's medical field, oxygen is an indispensable and crucial treatment method, widely used in the treatment of various diseases. Whether it is patients with respiratory diseases, such as COPD and pneumonia, who need oxygen to improve respiratory function and relieve hypoxia symptoms, or postoperative patients recovering from surgery, oxygen plays a key role in helping the body's functions recover quickly.

[0003] However, precise control of oxygen flow rate is crucial in actual oxygen therapy. Patients at different stages of their condition have vastly different oxygen flow requirements. For example, patients with mild hypoxia may only require a low and stable oxygen flow rate, while critically ill patients require a rapid and precise adjustment to a high flow rate in emergencies. However, existing medical oxygen regulators have several drawbacks. In terms of adjustment precision, they are difficult to finely adjust, resulting in either too much or too little oxygen being delivered to the patient, affecting treatment effectiveness. Furthermore, their structures are often overly complex, making oxygen flow control cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a medical oxygen regulating valve, which aims to solve the problem that existing medical oxygen regulating valves are difficult to achieve fine adjustment of oxygen and the adjustment process is time-consuming and laborious.

[0005] The present invention adopts the following technical solution:

[0006] The medical oxygen regulating valve includes a valve body, in which an air inlet chamber and a pair of air outlet chambers are formed at the front and rear respectively. The air inlet chamber is connected to the two air outlet chambers. An adjusting component is provided in the air outlet chamber. The adjusting component includes a fixing sleeve, a fixing ring at the front end of the fixing sleeve, and an air outlet plate at the rear end. The fixing ring and the air outlet plate are fixed to the inner wall of the air outlet chamber. A matching adjusting sleeve is provided in the fixing sleeve. The adjusting sleeve and the fixing sleeve are respectively provided with inner and outer air outlet grooves. A short post is provided on the adjusting sleeve, which extends out of the valve body and is provided with an adjusting lever.

[0007] Furthermore, both the fixing sleeve and the valve body have adjustment grooves corresponding to the short column.

[0008] Furthermore, the side wall of the fixed sleeve forms a sealing cavity within the air outlet cavity, and the adjusting groove is located within the sealing cavity.

[0009] Furthermore, the air outlet plate has several air outlet holes on the outer periphery of the fixed sleeve.

[0010] Furthermore, the inner wall of the front side of the valve body is provided with a matching plug corresponding to the inlet of the fixed sleeve.

[0011] Furthermore, an indicator mark is formed on the valve body corresponding to the adjusting lever, and an arrow is provided on the adjusting lever pointing towards the indicator mark.

[0012] Furthermore, the valve body has an air inlet connector and an air outlet connector respectively corresponding to the air inlet chamber and the air outlet chamber.

[0013] The beneficial effects of this utility model are:

[0014] 1. By coordinating the inner and outer air outlet grooves on the adjusting sleeve and the fixed sleeve, precise fine-tuning of oxygen flow can be achieved. Operators can precisely control the overlap area of ​​the inner and outer air outlet grooves by moving the adjusting lever back and forth according to the patient's specific needs, thereby accurately adjusting the oxygen flow to meet the treatment requirements of different patients.

[0015] 2. The adjustment lever and indicator marks make the operation of the regulating valve more intuitive and convenient. Operators can easily adjust the oxygen flow rate by simply observing the correspondence between the arrow and the indicator marks, thus improving the efficiency and accuracy of operation.

[0016] 3. The plug effectively prevents oxygen leakage and ensures the sealing of the regulating valve. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0024] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0025] Combination Figure 1-5 As shown, the medical oxygen regulating valve includes a valve body 1. An inlet chamber 2 and a pair of outlet chambers 3 are formed at the front and rear of the valve body 1, respectively. The inlet chamber 2 is connected to the two outlet chambers 3. An adjusting assembly is provided within each outlet chamber 3. The adjusting assembly includes a fixing sleeve 4, with a fixing ring 5 at the front end and an outlet plate 6 at the rear end. The fixing ring 5 and the outlet plate 6 are both fixed to the inner wall of the outlet chamber 3. A matching adjusting sleeve 7 is provided within the fixing sleeve 4. Inner and outer outlet grooves are respectively formed on the adjusting sleeve 7 and the fixing sleeve 4, with the inner outlet groove marked 91 and the outer outlet groove marked 92. A short post 10 is provided on the adjusting sleeve 7, extending out of the valve body 1 and equipped with an adjusting lever 11.

[0026] In today's medical field, oxygen is an indispensable and crucial therapeutic tool, widely used in the treatment of various diseases. When using oxygen for therapy, this medical oxygen regulating valve can be used to precisely control the oxygen flow rate, thus adapting to patients at different stages of their condition.

[0027] In this structure, the valve body is the main component of the regulating valve, with an inlet chamber and a pair of outlet chambers formed at its front and rear, respectively. The inlet chamber receives oxygen from the oxygen supply source, while the outlet chambers deliver the regulated oxygen to the patient's end. The inlet chamber is connected to the two outlet chambers to ensure that oxygen can flow smoothly from the inlet chamber to the outlet chamber.

[0028] The valve body 1 has an inlet connector 12 and an outlet connector 13 corresponding to the inlet chamber 2 and outlet chamber 3, respectively. The inlet connector is used to connect to oxygen supply equipment (such as oxygen cylinders, oxygen concentrators, etc.), and the outlet connector is used to connect to oxygen inhalation equipment (such as oxygen masks, nasal cannulas, etc.), facilitating the input and output of oxygen. Furthermore, the same oxygen regulating valve can supply oxygen to two patients simultaneously through the two outlet connectors.

[0029] As a specific structure, such as Figure 1-2 The fixed sleeve 4 and the valve body 1 each have an adjustment groove 14 corresponding to the short column 10. An adjustment component is provided in each air outlet chamber to adjust the oxygen flow rate. The two sets of adjustment components are set separately and can be adjusted independently during use without interfering with each other.

[0030] In practical use, when adjusting the oxygen flow rate from the outlet chamber using the adjustment component, simply move the adjustment lever. The lever, via the short column, moves the adjustment sleeve back and forth. During this process, the overlapping area of ​​the inner and outer outlet grooves on the adjustment sleeve and the fixed sleeve changes accordingly, and the oxygen flow rate also changes. That is, oxygen enters from the inlet of the fixed sleeve, passes through the overlapping portion of the inner and outer outlet grooves, and then flows from the outlet plate to the outlet connector. Of course, if the adjustment lever is stopped, it will not move due to friction.

[0031] The oxygen flow rate is adjusted by manipulating the adjusting lever, which moves the short column within the adjusting groove, causing the adjusting sleeve to slide back and forth within the fixed sleeve. The adjusting groove serves two purposes: it avoids the short column and it limits the distance the short column can move.

[0032] like Figure 4 The side wall of the fixed sleeve 4 forms a sealing cavity 19 within the air outlet cavity 3, and the adjusting groove 14 is located within the sealing cavity. The sealing cavity within the air outlet cavity effectively prevents oxygen leakage from the adjusting groove, thus improving the safety and stability of the regulating valve.

[0033] like Figure 3 The gas outlet plate 6 has several gas outlet holes 15 located on the outer periphery of the fixed sleeve 4. When oxygen enters from the inlet of the fixed sleeve, it passes through the overlapping part of the inner and outer gas outlet grooves, and then flows from the gas outlet holes on the gas outlet plate to the gas outlet connector. These gas outlet holes allow the oxygen flowing out from the inner and outer gas outlet grooves to diffuse evenly into the gas outlet chamber, avoiding concentrated oxygen outflow that would cause pressure unevenness and ensuring the stability of oxygen output.

[0034] In this structure, a matching plug 16 is provided on the inner front wall of the valve body 1 corresponding to the inlet of the fixed sleeve 4. As shown in the diagram, when the adjusting lever is moved forward, the short column drives the adjusting sleeve forward. During this process, the overlapping area of ​​the inner and outer air outlet grooves on the adjusting sleeve and fixed sleeve gradually decreases until the adjusting lever is moved to the closed position. At this point, the plug is inserted into the inlet of the fixed sleeve, the air outlet chamber is closed, and the inner and outer air outlet grooves no longer overlap, further closing the air outlet chamber and preventing oxygen from seeping into it, thus improving the sealing performance. Similarly, when the adjusting lever is moved backward, the overlapping area of ​​the inner and outer air outlet grooves gradually increases, and the oxygen flow rate through the air outlet chamber gradually increases.

[0035] like Figure 5 The valve body 1 has an indicator mark 17 corresponding to the adjusting lever 11, and the adjusting lever 11 has an arrow 18 pointing towards the indicator mark 17. The indicator mark and arrow allow the operator to intuitively understand the current oxygen flow rate adjustment, improving the accuracy and efficiency of adjustment. The operator can quickly determine the current oxygen flow rate based on the position of the arrow pointing to the indicator mark and make precise adjustments.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
