Description

Technical Field

[0001] The utility model relates to the technical field of right heart acoustic contrast examination equipment, and particularly relates to a Valsalva maneuver pressure tester. Background Art

[0002] A necessary condition for the diagnosis of patent foramen ovale is a Valsalva maneuver pressure tester. During the examination, doctors estimate the force exerted by the patient during the Valsalva maneuver to determine whether the patient's force is up to standard, and formulate standardized data based on the pressure value to assist in evaluating the severity of the patient's disease.

[0003] Currently, the method for judging whether a patient's Valsalva maneuver is up to standard by using a pressure tester to evaluate the pressure during the Valsalva maneuver is as follows: The patient blows air continuously through an air nozzle inserted into the mouth, and the air enters the pressure tester, causing the pressure of the pressure tester to reach 40 mmHg and maintain for 15 seconds.

[0004] In this way, since the air nozzle is inserted into the mouth, a certain amount of force is required to wrap it. At the same time, due to the requirements for the pressure value and the need for a continuous time, for some patients with insufficient lip muscle tone or endurance, when blowing air at the end, it is easy to cause air leakage between the air nozzle and the lips. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a Valsalva maneuver pressure tester, which can avoid the occurrence of air leakage between the air nozzle and the lips due to insufficient lip muscle tone or endurance during the blowing action of the Valsalva maneuver.

[0006] In order to achieve the above object, the utility model is realized by the following technical solutions: A Valsalva maneuver pressure tester, comprising:

[0007] An air pipe, connected to the tester body; and

[0008] A mouthpiece, the mouthpiece includes a connecting cover and a covering portion connected to the connecting cover. The connecting cover is connected to and communicates with the air pipe. The cross-section of the connecting cover gradually increases from the end close to the air pipe to the end away from the air pipe. The cross-section of the covering portion gradually decreases from the end close to the connecting cover to the end away from the connecting cover. An orifice is provided at the end of the covering portion away from the connecting cover, and the covering portion can cover the mouth through the orifice.

[0009] Further, the portions of the orifice on the left and right sides of the mouth protrude outward, and the portions on the upper and lower sides of the mouth contract inward.

[0010] Further, it further includes a sealing flexible pad, which is fixed along the edge of the cover opening.

[0011] Further, it further includes a side tube, which is arranged on the connecting cover and communicates with the outside. An overflow valve is tested on the side tube, and the overflow valve opens only when the detected pressure is at least greater than 40 mmg.

[0012] Further, it further includes a handle, which is arranged outside the connecting cover.

[0013] Further, there are two handles, and the two handles are arranged oppositely.

[0014] Advantages of the present utility model:

[0015] When the above-mentioned valsalva maneuver pressure tester is used, cover the cover of the covering part of the blowing nozzle on the mouth, and then continuously blow air into the blowing nozzle until the pressure detected by the tester body reaches 40 mmg and is maintained for 15 seconds to complete the test.

[0016] During the blowing process, since there is no need to wrap the mouth around the blowing nozzle, it is possible to avoid the phenomenon of air leakage between the air nozzle and the lips due to lack of muscle tension or endurance in the mouth in the later stage of blowing. In addition, since the cross-section of the connecting cover gradually increases from the end close to the trachea to the end far from the trachea, and the cross-section of the covering part gradually decreases from the end close to the connecting cover to the end far from the connecting cover, that is, the middle part of the blowing nozzle bulges outwards. During the blowing process, the mouth and face are in a suspended and separated state inside the blowing nozzle, so that part of the gas will not enter the gap between the face and the inner wall of the covering part, resulting in a sharp increase in the air pressure in the gap, and further resulting in the situation that the gas flows back out through the gap and the cover opening, further improving the test accuracy.

[0022] Hereinafter, embodiments of the technical solution of the present utility model will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 2 , the present utility model provides a tile-type action pressure tester, including a tester body 100, an air pipe 200 and a mouthpiece 300.

[0024] Specifically, the air pipe 200 is connected to the tester body 100. The mouthpiece 300 includes a connecting cover 310 and a covering part 320 connected to the connecting cover 310. The connecting cover 310 is connected to and communicates with the air pipe 200. The cross-section of the connecting cover 310 gradually increases from the end close to the air pipe 200 to the end far from the air pipe 200. The cross-section of the covering part 320 gradually decreases from the end close to the connecting cover 310 to the end far from the connecting cover 310. The end of the covering part 320 far from the connecting cover 310 is provided with a mouth 330 of the cover. The covering part 320 can cover the mouth through the mouth 330 of the cover.

[0025] During use, cover the mouth 330 of the covering part 320 of the mouthpiece 300 on the mouth, and then continuously blow air into the mouthpiece 300 until the pressure detected by the tester body 100 reaches 40mmg and is maintained for 15 seconds to complete the test.

[0026] During the blowing process, since it is not necessary to wrap the mouthpiece 300 with the mouth, the phenomenon of air leakage between the air nozzle and the lips due to lack of lip muscle tone or insufficient endurance in the later stage of blowing can be avoided. In addition, since the cross-section of the connecting cover 310 gradually increases from the end close to the air pipe 200 to the end far from the air pipe 200, and the cross-section of the covering part 320 gradually decreases from the end close to the connecting cover 310 to the end far from the connecting cover 310, that is, the middle part of the mouthpiece 300 bulges outwards. During the blowing process, the mouth and face are in a suspended and separated state inside the mouthpiece 300, so that part of the gas will not enter the gap between the face and the inner wall of the covering part 320, resulting in a sharp increase in the air pressure in the gap, and then the gas flowing back out through the gap and the mouth 330 of the cover. This further improves the test accuracy.

[0027] In specific implementation, the portions of the mask opening 330 on the left and right sides of the mouth can be protruded outward, and the portions on the upper and lower sides of the mouth can be contracted inward. That is, by making the shape of the mask opening 330 adapt to the shape of the human mouth, the sealing performance between the mask opening 330 and the face can be improved. In addition, a sealing flexible pad 400 can be fixed to the edge of the mask opening 330 to further enhance the sealing performance through the sealing flexible pad 400.

[0028] As a preferred implementation manner, the Valsalva maneuver pressure tester further includes a side tube 500. The side tube 500 is disposed on the connecting cover 310 and communicates with the outside. An overflow valve 510 is provided on the side tube 500, and the overflow valve 510 opens only when the detected pressure is greater than at least 40 mmg.

[0029] During the blowing process, when the patient blows too much gas into the mouthpiece 300, it is easy to cause the air pressure in the air nozzle to rise sharply. When the air pressure is too high, it is easy for the gas to leak back from the mask opening 330. Therefore, as a preference, the tester further includes a side tube 500. The side tube 500 is disposed on the connecting cover 310 and communicates with the outside. An overflow valve 510 is provided on the side tube 500, and the overflow valve 510 opens only when the detected pressure is at least greater than 40 mmg.

[0030] In the normal state, when the overflow valve 510 is in the closed state, when the overflow valve 510 detects that the air pressure is greater than 40 mmg, it opens, allowing some gas to flow out through the side tube 500, thereby ensuring that the air pressure in the air nozzle is maintained at least at 40 mmg. In specific implementation, for safety reasons, the safety value of the overflow valve 510 can be set to about 45 mmg.

[0031] As another preferred implementation manner, the pressure tester further includes a handle 600. The handle 600 is disposed outside the connecting cover 310. For convenient operation, two handles 600 can be provided, and the two handles 600 are disposed opposite to each other. This facilitates the operator to hold the handle 600 for operation.

[0032] The above-mentioned Valsalva maneuver pressure tester:

[0033] During the blowing process, since there is no need to wrap the blowing nozzle 300 with the mouth, the phenomenon of air leakage between the air nozzle and the lips caused by lack of lip muscle tension or insufficient endurance in the later stage of blowing can be avoided. In addition, since the cross-section of the connecting cover 310 gradually increases from the end close to the trachea 200 to the end far from the trachea 200, and the cross-section of the covering part 320 gradually decreases from the end close to the connecting cover 310 to the end far from the connecting cover 310, that is, the middle part of the blowing nozzle 300 bulges outwards. During the blowing process, the mouth and face are in a suspended and separated state inside the blowing nozzle 300, so that part of the gas will not enter the gap between the face and the inner wall of the covering part 320, resulting in a sharp increase in the air pressure in the gap, and further causing the gas to flow out reversely through the gap and the nozzle opening 330. This further improves the test accuracy.

[0034] Meanwhile, by setting the sealing flexible pad 400, the sealing performance between the nozzle opening 330 and the mouth can be further improved; through the side pipe 500 and the overflow valve 510, when the air pressure in the air nozzle is higher than the set value, pressure relief can be carried out to prevent the occurrence of reverse air leakage due to excessive air pressure in the air nozzle.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
