Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a front-end pressure test connector for assisting in the action of a valve. Background Technology
[0002] The Valsalva maneuver involves taking a deep breath, holding it, and then forcefully exhaling. During exhalation, the epiglottis is forced to close, thus blocking the airway. This action increases the pressure inside the chest cavity, thereby affecting blood circulation and the state of autonomic nervous system function.
[0003] In right ventricular echocardiography, doctors connect a pressure gauge to a syringe barrel and have the patient blow air into it. The pressure gauge then measures the pressure of the patient's exhalation, allowing the doctor to estimate the force exerted by the patient during the Vater exercise to determine if the effort level is within acceptable limits and to help assess the severity of the patient's condition. However, using a syringe barrel as a connector for the pressure gauge can be inconvenient for patients due to its small diameter, making the Vater exercise test difficult.
[0004] Therefore, this utility model provides a front-end pressure test connector for assisting the action of the bearing to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front-end pressure test connector for assisting the action of a valve, comprising a mouthpiece housing, an air inlet on the top surface of the mouthpiece housing and an air outlet on the bottom surface of the mouthpiece housing, a silicone pad connected to the top surface of the mouthpiece housing, and a connecting tube connected to the bottom surface of the mouthpiece housing outside the air outlet, one end of the connecting tube extending into a threaded groove, the threaded groove being formed on the inner surface of the top of the connector.
[0007] In order to facilitate the assembly and disassembly of the connecting pipe and the connector, as a preferred front-end pressure test connector for assisting the action of the bearing in this utility model, the outer surface of one end of the connecting pipe extending into the threaded groove is provided with surface threads, and the connecting pipe forms a threaded connection with the threaded groove through the surface threads.
[0008] In order to improve the sealing between the connecting pipe and the connector, as a preferred front-end pressure test connector for assisting the action of the valve in this utility model, a sealing ring is connected to the bottom surface of the threaded groove, and the top surface of the sealing ring is in contact with the bottom surface of the connecting pipe.
[0009] In order to enable the gas flowing inside the mouthpiece housing to be delivered to the connector through the connecting pipe, the position of the internal space of the connector is connected to the position of the internal space of the connecting pipe as a preferred front-end pressure test connector for assisting the valve action of this utility model.
[0010] To facilitate the fixing of the mouthpiece housing to the head, as a preferred front-end pressure test connector for assisting the valve-like action of this utility model, connecting blocks are connected to both sides of the top of the mouthpiece housing. A first elastic strap is connected to one side of one connecting block, and a second elastic strap is connected to one side of the other connecting block. The surface of the first elastic strap facing the mouthpiece housing is connected to a Velcro surface, and the surface of the second elastic strap away from the mouthpiece housing is connected to a Velcro hook surface. The size and position of the Velcro surface match the size and position of the Velcro hook surface.
[0011] In order to facilitate the assembly and disassembly of the first and second elastic straps, as a preferred front-end pressure test connector for assisting the action of the valve in this utility model, bolts are connected through the first and second elastic straps on the side surface away from the connecting block, and the other end of the bolts is threaded into a fixing hole opened on the side surface of the connecting block away from the mouthpiece housing.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention connects the connector at the bottom of the mouthpiece housing to the connector of the pressure gauge pipeline, and then fits the mouthpiece housing against the patient's face, allowing the patient's exhaled air to be delivered to the pressure gauge through the mouthpiece housing, thereby estimating the force exerted by the patient when performing the Valsalva maneuver. In this way, the patient can easily perform the blowing action through the mouthpiece housing with a large air inlet, which brings convenience to the Valsalva maneuver test.
[0014] This invention utilizes the interplay of a first elastic strap, a second elastic strap, and the hook and loop sides of the Velcro strap to allow the operator to secure the mouthpiece housing to the patient's head using the elastic straps.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a front pressure test connector for assisting the action of a blowpipe, comprising a mouthpiece housing 1, an air inlet 2 on the top surface of the mouthpiece housing 1, the arc shape of the air inlet 2 matching the arc shape of the face, and an air outlet 3 on the bottom surface of the mouthpiece housing 1, a silicone pad 4 connected to the top surface of the mouthpiece housing 1, the silicone pad 4 can increase the degree of fit with the patient's face, and at the same time improve the comfort of wearing the mouthpiece housing 1, a connecting tube 5 connected to the bottom surface of the mouthpiece housing 1 outside the air outlet 3, one end of the connecting tube 5 extending into a threaded groove 6, the threaded groove 6 being opened on the inner surface of the top of the connector 7.
[0023] Preferably, the outer surface of one end of the connecting pipe 5 extending into the threaded groove 6 is provided with surface threads 8, and the connecting pipe 5 forms a threaded connection with the threaded groove 6 through the surface threads 8.
[0024] In practical use, the connecting tube 5 can be screwed into the threaded groove 6 on the connector 7 through the surface thread 8, so that the connecting tube 5 and the connector 7 are connected together. Then, by turning the connecting tube 5 in the opposite direction, one end of the connecting tube 5 can be separated from the threaded groove 6, so that the mouthpiece housing 1 can be separated from the connector 7 through the connecting tube 5, allowing the operator to perform maintenance operations on the mouthpiece housing 1.
[0025] Preferably, a sealing ring 9 is connected to the bottom surface of the threaded groove 6, and the top surface of the sealing ring 9 is in contact with the bottom surface of the connecting pipe 5.
[0026] In practical use, when the connecting pipe 5 is screwed into the threaded groove 6 on the connector 7 through the surface thread 8, the sealing ring 9 will be between the connecting pipe 5 and the connector 7. At this time, the sealing ring 9 can improve the sealing between the connecting pipe 5 and the connector 7, ensuring that the flowing gas will not escape from the threaded groove 6.
[0027] Preferably, the position of the internal space of the connector 7 is connected to the position of the internal space of the connecting pipe 5.
[0028] In actual use, the patient blows air towards the air inlet 2, and the exhaled air enters the connecting tube 5 through the air outlet 3, and is then delivered to the pressure gauge pipeline through the connector 7 connected to the connecting tube 5.
[0029] Preferably, connecting blocks 10 are connected to both sides of the top end of the mouthpiece housing 1. A first elastic strap 11 is connected to one side of one connecting block 10, and a second elastic strap 12 is connected to one side of the other connecting block 10. A hook and loop fastener 15 is connected to the side of the first elastic strap 11 facing the mouthpiece housing 1, and a hook and loop fastener 16 is connected to the side of the second elastic strap 12 away from the mouthpiece housing 1. The size and position of the hook and loop fastener 15 match the size and position of the hook and loop fastener 16.
[0030] In actual use, the silicone pad 4 on the mouthpiece housing 1 is made to fit against the patient's face. Then, the first elastic strap 11 and the second elastic strap 12 are pulled to make the Velcro loop 15 on the first elastic strap 11 fit together with the Velcro hook 16 on the second elastic strap 12. In this way, the first elastic strap 11 and the second elastic strap 12 will fix the mouthpiece housing 1 on the patient's head.
[0031] Preferably, bolts 13 are connected through the first elastic strap 11 and the second elastic strap 12 on the side surface away from the connecting block 10, and the other end of the bolt 13 is threaded into the fixing hole 14 opened on the side surface of the connecting block 10 away from the mouthpiece housing 1.
[0032] In practical use, the bolt 13 is inserted through the first elastic strap 11 and the second elastic strap 12 and screwed into the fixing hole 14 to install and fix the first elastic strap 11 and the second elastic strap 12 on the connecting block 10. Then, the bolt 13 is screwed again to separate one end of the bolt 13 from the fixing hole 14, so that the first elastic strap 11 and the second elastic strap 12 can be removed for maintenance and replacement.
[0033] Working principle: When using the front pressure test connector of the auxiliary valve action, connect the connector 7 at the bottom of the mouthpiece housing 1 to the pressure gauge pipe connector for the valve action test. Then, make the silicone pad 4 on the mouthpiece housing 1 fit against the patient's face. Pull the first elastic strap 11 and the second elastic strap 12 to make the Velcro loop 15 on the first elastic strap 11 fit together with the Velcro hook 16 on the second elastic strap 12. In this way, the first elastic strap 11 and the second elastic strap 12 will fix the mouthpiece housing 1 on the patient's head, so that the patient's mouth is positioned at the air inlet 2 of the mouthpiece housing 1. When the patient blows air towards the air inlet 2, the exhaled air will enter the connecting tube 5 through the air outlet 3, and then be connected through the connecting tube 5. The connector 7 is connected to the pressure gauge pipeline, so that the pressure gauge will test the pressure of the patient's exhaled air. This helps the doctor to judge the force the patient exerts when performing the Watts maneuver, to determine whether the patient's Watts maneuver is up to standard, and to help the doctor classify the severity of the disease under different pressures. In this way, the patient can easily perform the blowing action through the mouthpiece housing 1 with the larger air inlet 2, which facilitates the testing of the Watts maneuver. Secondly, pulling the first elastic strap 11 and the second elastic strap 12 can make the hook and loop side 15 of the Velcro and the hook side 16 fit together, so that the mouthpiece housing 1 can be worn and fixed on the head of different patients. This prevents the mouthpiece housing 1 from falling off directly if the patient accidentally releases their hand, thus ensuring the stability of the test connector during use.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
