In addition, the deflation auxiliary part pulls the air-closing pad to automatically close the blowing port through the expansion effect of the exhalation bag during blowing, thereby prompting the patient that the amount of gas blown out has met the demand, realizing automatic closing and sealing during blowing, and also realizing automatic closing after the blowing is full, effectively ensuring sufficient blowing volume.

Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to an intestinal microecological methane and hydrogen breath detection device. Background Art

[0002] The medical breath detection device is a commonly used detection equipment in hospitals. It has high detection sensitivity, high detection rate and compliance rate, and is painless to patients. It is the most popular intestinal microecological gas detection device among patients.

[0003] The exhalation detection device mainly includes a detector and an exhalation bag. The exhalation bag is convenient, healthy and hygienic to use, and can effectively prevent cross-infection between patients. However, although the existing exhalation bags are convenient to use, they are not effective in collecting gas. This is mainly because patients cannot determine whether the amount of gas blown out meets the detection conditions when using them. In addition, the sealing of the existing exhalation bags is not good. As soon as the exhalation bag leaves the patient's mouth, gas leakage will occur, resulting in the exhaled volume failing to meet the detection requirements.

[0004] For this reason, we adopt this technical solution to solve the problem that the existing exhalation bag is not well used. Summary of the invention

[0005] The purpose of the present invention is to improve the exhalation bag in the prior art, and to provide an intestinal microecological methane and hydrogen exhalation detection device compared to the prior art, by adding a sealing pad on the basis of the existing exhalation bag, utilizing the blowing force during exhalation to open the sealing pad, and utilizing the elastic force to allow the sealing pad to automatically close after the exhalation is completed, thereby effectively preventing gas leakage and maintaining a sufficient amount of gas to meet the detection requirements, and by adding a deflation auxiliary part inside the exhalation bag, relying on the elastic force of the deflation auxiliary part, the exhalation bag can be automatically deflated after being inserted into the gas detector body, so as to effectively help all the gas in the exhalation bag be released into the gas detector body, in addition, through the expansion effect of the exhalation bag during blowing, the deflation auxiliary part pulls the air-closing pad to automatically close the blowing port, thereby prompting the patient that the amount of gas blown out has met the demand, effectively avoiding the occurrence of detection failure problems caused by insufficient blowing volume.

[0006] It can realize automatic closing and sealing during blowing, and can also realize automatic closing after full blowing, effectively ensuring sufficient blowing volume.

[0007] Furthermore, the sealing gasket includes a hollow plate, and the side walls of the two hollow plates that are in contact with each other are fixedly inlaid with magnetic strips that are magnetically attracted to each other, and the sides of the hollow plates are fixedly connected with sealing rings. When the two sealing gaskets are in a closed state, the magnetic attraction of the magnetic strips can make the two sealing gaskets tightly closed, and the sealing rings on the sides can also effectively prevent air leakage, thereby effectively improving the sealing effect after blowing.

[0008] Furthermore, a sealing groove matching the sealing ring is provided on the side wall of the mounting ring away from the blowing port, and the sealing ring is made of silicone material, which has a good sealing effect. When the sealing gasket is in a closed state, the sealing ring is in close contact with the sealing groove, thereby effectively improving the sealing effect.

[0009] Optionally, elastic mounting strips are fixedly connected to the upper and lower inner walls of the self-sealing air blowing tube away from the sealing pad, and an air-closing pad is fixedly connected to the elastic mounting strips. The upper and lower air-closing pads are closed and connected to each other, and pulling ropes are fixedly connected between the side walls of the two air-closing pads away from the sealing pad and the deflation auxiliary component. When gas is blown into the exhalation bag, the exhalation bag begins to expand. The pulling effect of the expansion of the exhalation bag causes the deflation auxiliary component to deform. When the deflation auxiliary component is deformed, the air-closing pad is pulled by the pulling rope. When the amount of gas in the exhalation bag is sufficient, the two air-closing pads will be in a closed state. At this time, the patient cannot continue to blow air into the exhalation bag, thereby reminding the patient that the gas volume has been blown enough, effectively avoiding the occurrence of detection failure caused by insufficient gas blowing.

[0010] Optionally, the elastic mounting strip is made of elastic material, and the air-sealing cushion is in a horizontal state in a natural state. During the blowing process, the exhalation bag continues to expand with the increase of the blowing amount. The expansion effect causes the deflation auxiliary component to continuously deform and pull the pulling rope. When the amount of gas blown in is sufficient, the pulling rope pulls the air-sealing cushion to a closed state. When the exhalation bag is inserted into the gas detector body for deflation, the rebound force of the deflation auxiliary component causes the air-sealing cushion to open, thereby realizing automatic deflation, effectively helping the exhalation bag to release all the gas.

[0011] Furthermore, the deflation auxiliary component includes multiple elastic support frames, and a connecting net is fixedly connected between two adjacent elastic support frames. The elastic support frames can deform when gas is blown into them, and can automatically restore the deformation when deflated, thereby achieving the purpose of automatic deflation, and the connecting net is to avoid affecting the blowing of gas.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] (1) This scheme adds a sealing pad to the existing exhalation bag, uses the blowing force during exhalation to open the sealing pad, and uses the elastic force to automatically close the sealing pad after exhalation, thereby effectively preventing gas leakage and maintaining a sufficient amount of gas to meet the detection requirements. In addition, a deflation auxiliary part is added to the inside of the exhalation bag. Relying on the elastic force of the deflation auxiliary part, the exhalation bag can be automatically deflated after being inserted into the gas detector body, effectively helping to release all the gas in the exhalation bag into the gas detector body. In addition, the deflation auxiliary part can pull the air-closing pad to automatically close the blowing port through the expansion effect of the exhalation bag during blowing, thereby prompting the patient that the amount of gas blown out has met the demand, effectively avoiding the problem of detection failure caused by insufficient blowing volume, realizing automatic closing and sealing during blowing, and also realizing automatic closing after full blowing, effectively ensuring sufficient blowing volume.

[0014] (2) The sealing gasket includes a hollow plate, and the side walls of the two hollow plates that are in contact with each other are fixedly embedded with magnetic strips that attract each other, and the sides of the hollow plates are fixedly connected with sealing rings. When the two sealing gaskets are in a closed state, the magnetic attraction of the magnetic strips can make the two sealing gaskets tightly closed, and the sealing rings on the sides can also effectively prevent air leakage, thereby effectively improving the sealing effect after blowing.

[0015] (3) A sealing groove matching the sealing ring is provided on the side wall of the mounting ring away from the blowing port, and the sealing ring is made of silicone material, which has a good sealing effect. When the sealing gasket is in a closed state, the sealing ring is in close contact with the sealing groove, thereby effectively improving the sealing effect.

[0016] (4) The inner walls of the upper and lower sides of the self-sealing insufflation tube away from the sealing pad are fixedly connected with elastic mounting strips, and the elastic mounting strips are fixedly connected with an air-closing pad. The upper and lower air-closing pads are closed and connected to each other. Pulling ropes are fixedly connected between the side walls of the two air-closing pads away from the sealing pad and the deflation auxiliary parts. When gas is blown into the exhalation bag, the exhalation bag begins to expand. The pulling effect of the inflated exhalation bag causes the deflation auxiliary parts to deform. When the deflation auxiliary parts are deformed, the air-closing pads are pulled by the pulling ropes. When the amount of gas in the exhalation bag is sufficient, the two air-closing pads are closed. At this time, the patient cannot continue to blow air into the exhalation bag, thereby reminding the patient that the amount of gas has been blown enough, effectively avoiding the problem of detection failure caused by insufficient gas insufflation.

[0017] (5) The elastic mounting strip is made of elastic material, and the air-sealing cushion is in a horizontal state under the natural state. During the blowing process, the exhalation bag expands continuously with the increase of the blowing amount. The expansion effect causes the deflation auxiliary component to continuously deform and pull the pull rope. When the amount of gas blown in is sufficient, the pull rope pulls the air-sealing cushion to a closed state. When the exhalation bag is inserted into the gas detector body for deflation, the rebound force of the deflation auxiliary component causes the air-sealing cushion to open, thereby achieving automatic deflation, effectively helping the exhalation bag to release all the gas.

[0018] (6) The deflation auxiliary component includes a plurality of elastic support frames, and a connecting net is fixedly connected between two adjacent elastic support frames. The elastic support frames can be deformed when gas is blown into them, and can automatically restore the deformation when deflated, thereby achieving the purpose of automatic deflation, and the connecting net is to avoid affecting the blowing of gas.

DETAILED DESCRIPTION

[0029] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] A device for detecting intestinal microecological methane and hydrogen breath, please refer to Figure 1 , 2 and Figure 4 , including a gas detector body 1, a plurality of exhalation bags 2 are inserted into the gas detector body 1, one end of the exhalation bag 2 is connected with an air blowing port 3, and the air blowing port 3 is located inside the exhalation bag 2, and one end is fixedly connected with a self-sealing air blowing tube 4, and the inner wall of the self-sealing air blowing tube 4 near the air blowing port 3 is fixedly connected with a mounting ring 5, and the upper and lower sides of the mounting ring 5 are rotatably connected with sealing pads 6;

[0032] See also Figure 4 , 5 and Figure 6 The sealing gasket 6 includes a hollow plate 601, and the side walls of the two hollow plates 601 that are in contact with each other are fixedly inlaid with magnetic strips 602 that are magnetically attracted to each other, and the sides of the hollow plates 601 are fixedly connected with sealing rings 603. When the two sealing gaskets 6 are in a closed state, the magnetic attraction of the magnetic strips 602 can make the two sealing gaskets 6 tightly closed, and the sealing rings 603 on the sides can also effectively avoid air leakage, thereby effectively improving the sealing effect after blowing. A sealing groove matching the sealing ring 603 is provided on the side wall of the mounting ring 5 away from the blowing port 3, and the sealing ring 603 is made of silicone material, which has a good sealing effect. When the sealing gasket 6 is in a closed state, the sealing ring 603 is in close contact with the sealing groove, thereby effectively improving the sealing effect;

[0033] See also Figure 7 , 8 An elastic rope 7 (preferably made of rubber material, and other materials can also be selected according to actual needs) is fixedly connected between the side walls of the two sealing pads 6 close to the blowing port 3 and the inner wall of the self-sealing blowing tube 4. Two symmetrically distributed deflation auxiliary parts 8 are fixedly connected between the inner walls on both sides of the exhalation bag 2. The deflation auxiliary parts 8 include multiple elastic support skeletons 801 (preferably made of polyurethane elastic material, and other materials can also be selected according to actual needs), and a connecting net 802 is fixedly connected between two adjacent elastic support skeletons 801. The elastic support skeleton 801 can be deformed when gas is blown in, and can automatically restore the deformation when deflated, thereby achieving the purpose of automatic deflation. The connecting net 802 is to prevent the blowing of gas, and multiple elastic connecting wires 9 are fixedly connected between the two deflation auxiliary parts 8.

[0034] Embodiment 2:

[0035] Based on Example 1, please refer to Figure 3 , 4 , the inner walls of the upper and lower sides of the self-sealing blowing tube 4 away from the sealing pad 6 are fixedly connected with elastic mounting strips 10, the elastic mounting strips 10 are made of elastic material (polyurethane elastic material is preferred, and other materials can also be selected according to actual needs), and the elastic mounting strips 10 are in a horizontal state in the natural state, and the air-closing pad 11 is in a horizontal state. During the blowing process, the exhalation bag 2 continues to expand with the increase of the blowing amount, and the expansion effect causes the deflation auxiliary component 8 to continuously deform and pull the pulling rope 12. When the amount of gas blown in is sufficient, the pulling rope 12 pulls the air-closing pad 11 to a closed state, and when the exhalation bag 2 is inserted into the gas detector body 1 for deflation, the rebound force of the deflation auxiliary component 8 causes the air-closing pad 11 to open, thereby realizing automatic deflation, which effectively helps exhalation. The bag 2 releases all the gas, and an air-locking pad 11 is fixedly connected to the elastic mounting strip 10. The upper and lower air-locking pads 11 are closed and connected to each other. A pulling rope 12 is fixedly connected between the side walls of the two air-locking pads 11 away from the sealing pad 6 and the deflation auxiliary component 8. When gas is blown into the exhalation bag 2, the exhalation bag 2 begins to expand. The pulling effect of the expansion of the exhalation bag 2 causes the deflation auxiliary component 8 to deform. When the deflation auxiliary component 8 is deformed, the air-locking pad 11 is pulled by the pulling rope 12. When the amount of gas in the exhalation bag 2 is sufficient, the two air-locking pads 11 will be in a closed state. At this time, the patient cannot continue to blow air into the exhalation bag 2, thereby reminding the patient that the amount of gas has been blown enough, effectively avoiding the problem of detection failure caused by insufficient gas blowing.

[0036] The working principle of this solution is as follows: when in use, the patient holds the exhalation bag 2 with his hand, then holds the blowing port 3 in his mouth and starts to blow gas into the exhalation bag 2. Under the action of the blowing force, the sealing pad 6 is blown open, and then the gas begins to enter the exhalation bag 2. As the amount of gas blown in increases, the exhalation bag 2 continues to expand. While the exhalation bag 2 expands, the deflation auxiliary component 8 is pulled and deformed. As a result, the deflation auxiliary component 8 has a rebound force. During the deformation process, the deflation auxiliary component 8 pulls the air-closing pad 11 from a horizontal state to a closed state by pulling the rope 12. When the amount of gas in the exhalation bag 2 is sufficient, the air-closing cushion 11 reaches a closed state. At this time, the patient cannot blow gas into the exhalation bag 2, which reminds the patient that the gas in the exhalation bag 2 is full. When the exhalation bag 2 is inserted into the gas detector body 1, the interface on the gas detector body 1 pushes the sealing pad 6 open and starts to pump air. At the same time, the deflation auxiliary component 8 restores its deformation under the action of the rebound force, which can effectively help the exhalation bag 2 to release all the gas inside, thereby ensuring that the amount of gas entering the gas detector body 1 meets the detection requirements.

[0037] The above description is only the best implementation mode adopted by the present invention in combination with current practical needs, but the protection scope of the present invention is not limited thereto.
