Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, specifically to a bite-resistant ventilation tube for cardiovascular nursing. Background Technology

[0002] Cardiovascular diseases are common heart problems in clinical practice. Common cardiovascular diseases include angina pectoris, hypertension, arrhythmia, sudden death, heart failure, and myocardial infarction. Cardiovascular patients often experience difficulty breathing. During emergency care, it is necessary to open the airway, insert an oropharyngeal airway, suction sputum, administer oxygen, or perform subdiaphragmatic abdominal thrusts and chest compressions to provide life support and improve the success rate of nursing care and emergency care. During the rescue process, patients often have difficulty suctioning sputum, the tongue may fall back, and the airway may not be opened properly. In the early stages of rescue, a ventilator can be used to solve these problems.

[0003] Application number CN202120024961.1 discloses an anti-bite ventilation tube for cardiovascular nursing, comprising a tube body, an anti-bite block on the tube body, the anti-bite block being open-shaped, an installation hole at the end of the anti-bite block away from the opening, the tube body passing through the installation hole and extending out, a fixing block inside the anti-bite block, a tongue hole and a tube hole inside the fixing block, and a buffer mechanism between the fixing block and the anti-bite block, the buffer mechanism including a first spring near the opening end of the anti-bite block, the first spring being fixedly connected to the fixing block, a first mounting plate connected above the first spring, and a first connecting rod above the first mounting plate, the first connecting rod being fixedly connected to the anti-bite block; this device can effectively prevent patients from accidentally or uncontrollably biting themselves or biting off the tube during treatment by setting the anti-bite block, further improving the safety of the device.

[0004] The existing ventilation tubes are made of soft, molded material and are inserted directly into the patient's mouth. This makes it easy for the patient to bite themselves or break the tube during emergency treatment due to convulsions, which increases the difficulty of the rescue. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bite-proof ventilation tube for cardiovascular nursing, so as to solve the problems existing in the background art.

[0006] This invention provides the following technical solution: a cardiovascular nursing anti-bite ventilation tube, comprising a flexible tube, the flexible tube comprising an outer connecting tube and an inner ventilation tube, wherein the outer connecting tube is provided with an inflation switch, a fixing device, an occlusal device and a mouth-holding device, the inflation switch being movably connected to the outer connecting tube, the fixing device being fixedly connected to the outer connecting tube, the occlusal device being fixedly connected to the outer connecting tube, an inflation tube being fixedly connected to the side of the occlusal device, an inflation control device being fixedly connected to the other end of the inflation tube, the mouth-holding device being rotatably connected to the outer connecting tube, a first pressure sensor being provided on the occlusal device, a second pressure sensor being provided on the mouth-holding device, and a controller and an inflation pump being provided inside the inflation control device.

[0007] Furthermore, the support device includes a support plate, a support member is rotatably connected to the side of the support plate, a spring damping device is fixedly connected to the side of the support member, and a connecting slider is fixedly connected to the side of the spring damping device.

[0008] Furthermore, the inflation switch includes a connecting block, which is located at the center of the connecting slider. A connecting hollow tube is fixedly connected to the side of the connecting block. The connecting block is a slanted wheel. The left side of the connecting hollow tube passes through the engagement device and is fixedly connected to the connecting block. An inflation disc is fixedly connected to the right side of the connecting hollow tube. The inflation tube on the engagement device is also connected to the inflation disc through the connecting hollow tube. The inflation disc can be moved left and right on the hose by venting air into it. The inflation amount of the inflation switch controlled by the inflation control device is recorded as C1. The connecting hollow tube is a medical latex tube and is sleeved on the inner ventilation tube.

[0009] During use, air is introduced through the inflation control device, passing through the inflation tube and connecting hollow tube to the interior of the inflation disc. This pushes the inflation disc to slide relative to the hose, causing the connecting block, which is fixedly connected to the inflation disc, to move. Increased airflow causes the inflation disc to move to the left, which in turn moves the connecting block to the left. During contact with the connecting block, the connecting slider moves inward, causing the mouth support disc to contract inward, reducing the opening of the mouth support device. Conversely, decreased airflow causes the inflation disc to move to the right, which in turn moves the connecting block to the right. During contact with the connecting block, the connecting slider moves outward, causing the mouth support disc to expand outward, increasing the opening of the mouth support device. This allows for better control of the mouth support device's opening during use, changing with bite force to prevent unintentional excessive opening that could damage the oral cavity, thus improving the device's safety.

[0010] Furthermore, a limiting ring is movably connected to the hollow connecting tube. The limiting ring is disposed between the connecting block and the engagement device, and the limiting ring is fixedly connected to the outer connecting tube.

[0011] Furthermore, the occlusal device includes a housing, on which a plurality of upper occlusal cavities and lower occlusal cavities are formed. A ventilation connecting tube is provided at the center of the housing. The upper occlusal cavities and the housing are alternately positioned and opposite in direction. The housing and the ventilation connecting tube are made of medical PVC material. The ventilation connecting tube is hexagonal in shape and has high hardness.

[0012] Furthermore, the first pressure sensor is disposed between the air connection pipe and the outer shell. The upper occlusal cavity and the interior of the outer shell are connected, and each upper occlusal cavity is interconnected. The air inflator is connected to the interior of the upper occlusal cavity. The first sensor needs to be calibrated. Before use, the signal parameter command is activated. The air inside the occlusal device is discharged through the air inflation control device. At this time, the pressure value displayed by the pressure sensor is set to zero. Then, the occlusal device is slowly inflated. When the air saturation inside the occlusal device reaches 85%, inflation is stopped. The inflation amount of the occlusal device is recorded as C2. At this time, the pressure value displayed by the first pressure sensor reaches a certain value A1. The pressure value currently displayed by the first sensor is recorded. The pressure value of the first sensor during occlusal use is recorded as A2.

[0013] When the user bites the outer shell, the upper occlusal cavity and the outer shell can convert the pressure of the upper and lower teeth on the occlusal device into pressure in more directions, expanding the force-bearing area during biting. At the same time, during biting, the air inside the upper occlusal cavity is squeezed into the lower occlusal cavity. The upper occlusal cavity and the outer shell fit together, which can protect the user from injury during biting. The pressure sensor between the outer shell and the air connection tube can detect the biting force. The structure and material of the air connection tube can prevent the air connection tube from undergoing large deformation when the occlusal device is bitten, so as not to affect the normal use of the air tube.

[0014] Furthermore, the second sensor is mounted on a support plate made of elastic silicone, and the pressure value of the second sensor during use is recorded as B.

[0015] Furthermore, the controller includes a signal receiving device, a signal processing device, and a control device. The signal receiving device is linearly connected to the first sensor and the second sensor and is used to receive the numerical signals from the sensors. The signal processing device is used to process the relationship between the sensor numerical signals and the inflation amount of the inflation switch. The control device controls the inflation of the inflation switch and the inflation control device by receiving the signal processing device's model number.

[0016] Furthermore, the inflation amount of the inflation switch is "C1=[B / A2-A1]C2"; Wherein, B is the pressure value when the second sensor is in use, A2 is the pressure value when the first sensor is in use, A1 is the pressure value of the first pressure sensor when the occlusal device is inflated to 85%, C2 is the inflation amount when the occlusal device is inflated to 85%, and C1 is the inflation amount when the inflation switch is in use.

[0017] Beneficial effects: 1. This anti-bite ventilation tube for cardiovascular nursing uses an inflation control device for ventilation. The air passes through the inflation tube and connecting hollow tube to the inflation disc. Pushing the inflation disc causes the tubing to slide relative to it, moving the connecting block fixedly connected to the disc. Increased ventilation causes the inflation disc to move to the left, which in turn moves the connecting block to the left. During contact with the connecting block, the connecting slider moves inward, causing the mouthguard to contract inward, reducing the opening of the mouthguard. Conversely, decreased ventilation causes the inflation disc to move to the right, which in turn moves the connecting block to the right. During contact with the connecting block, the connecting slider moves outward, causing the mouthguard to expand outward, increasing the opening of the mouthguard. This allows for better control of the mouthguard opening during use, changing with bite force to prevent unintentional bites that could cause oral damage and improve device safety.

[0018] 2. This cardiovascular nursing anti-bite ventilation tube, when the user bites the outer shell, the upper occlusal cavity and the outer shell can convert the pressure of the upper and lower teeth on the occlusal device into pressure in more directions, expanding the force-bearing area during biting. At the same time, during biting, the air inside the upper occlusal cavity is squeezed into the lower occlusal cavity. The upper occlusal cavity and the outer shell fit together, which can protect the user from injury during biting. The pressure sensor between the outer shell and the ventilation connecting tube can detect the biting force. The structure and materials of the ventilation connecting tube can prevent the ventilation connecting tube from undergoing large deformation when the occlusal device is bitten, so as not to affect the normal use of the ventilation tube.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figure 1-2 , Figure 4 A cardiovascular nursing anti-bite ventilation tube includes a flexible tube 1, which comprises an outer connecting tube 101 and an inner ventilation tube 102. The outer connecting tube 101 is equipped with an inflation switch 2, a fixing device 3, an occlusive device 4, and a mouth-holding device 5. The inflation switch 2 is movably connected to the outer connecting tube 101, the fixing device 3 is fixedly connected to the outer connecting tube 101, the occlusive device 4 is fixedly connected to the outer connecting tube 101, an inflation tube 6 is fixedly connected to the side of the occlusive device 4, and an inflation control device 7 is fixedly connected to the other end of the inflation tube 6. The mouth-holding device 5 is rotatably connected to the outer connecting tube 101. The occlusive device 4 is equipped with a first pressure sensor, the mouth-holding device 5 is equipped with a second pressure sensor, and the inflation control device 7 contains a controller and an inflation pump.

[0023] The support device 5 includes a support plate 501, a support member 502 is rotatably connected to the side of the support plate 501, a spring damping device 504 is fixedly connected to the side of the support member 502, and a connecting slider 503 is fixedly connected to the side of the spring damping device 504.

[0024] The inflation switch 2 includes a connecting block 203, which is located at the center of the connecting slider 503. A connecting hollow tube 202 is fixedly connected to the side of the connecting block 203. The connecting block 203 is a slanted wheel. The left side of the connecting hollow tube 202 passes through the engagement device 4 and is fixedly connected to the connecting block 203. An inflation disc 201 is fixedly connected to the right side of the connecting hollow tube 202. The inflation tube 6 on the engagement device 4 is also connected to the inflation disc 201 through the connecting hollow tube 202. The inflation disc 201 can move left and right on the hose 1 by venting air into it. The inflation control device 7 records the inflation amount of the inflation switch 2 as C1. The connecting hollow tube 202 is a medical latex tube and is sleeved on the inner ventilation tube 102.

[0025] During use, air is introduced via the inflation control device 7, passing through the inflation pipe 6 and the connecting hollow pipe 202 to the interior of the inflation disc 201. This pushes the inflation disc 201 to slide relative to the hose 1, causing the connecting block 203, which is fixedly connected to the inflation disc 201, to move. Increased airflow causes the inflation disc 201 to move to the left, which in turn causes the connecting block 203 to move to the left. During contact with the connecting block 203, the connecting slider 503 moves inward, causing the support plate 501 to retract inward, reducing the support... The mouth opening of the mouth device 5 is reduced; when the air volume decreases, the inflation disc 201 moves to the right, which in turn moves the connecting block 203 to the right. The connecting slider 503 moves outward during contact with the connecting block 203, causing the mouth support disc 501 to expand outward, thus increasing the opening of the mouth support device 5. During use, the opening of the mouth support device 5 can be better controlled. It changes with the bite force during use, avoiding damage to the oral cavity caused by the user's unconscious bite, thus improving the safety of the device.

[0027] The occlusal device 4 includes a housing 402, on which a plurality of upper occlusal cavities 401 and lower occlusal cavities 403 are provided. A ventilation connecting pipe 404 is provided at the center of the housing 402. The upper occlusal cavities 401 and the housing 402 are alternately positioned and opposite in direction. The housing 402 and the ventilation connecting pipe 404 are made of medical PVC material. The ventilation connecting pipe 404 is hexagonal in shape and has high hardness.

[0028] The first pressure sensor is located between the air connection pipe 404 and the outer shell 402. The upper occlusal cavity 401 and the outer shell 402 are connected, and each upper occlusal cavity 401 is interconnected. The air inflator 6 is connected to the inside of the upper occlusal cavity 401. The first sensor needs to be calibrated. Before use, the signal parameter command is activated. The air inside the occlusal device 4 is discharged through the air inflation control device 7. At this time, the pressure value displayed by the pressure sensor is set to zero. Then, the occlusal device 4 is slowly inflated. When the air saturation inside the occlusal device 4 reaches 85%, the inflation is stopped. The inflation amount of the occlusal device 4 is recorded as C2. At this time, the pressure value displayed by the first pressure sensor reaches a certain value A1. The pressure value currently displayed by the first sensor is recorded. The pressure value of the first sensor when in occlusal use is recorded as A2.

[0029] When the user bites the outer shell 402, the upper occlusal cavity 401 and the outer shell 402 can convert the pressure of the upper and lower teeth on the occlusal device 4 into pressure in more directions, expanding the force-bearing area during biting. At the same time, during biting, the gas inside the upper occlusal cavity 401 is squeezed into the lower occlusal cavity 403. The upper occlusal cavity 401 and the outer shell 402 fit together, which can protect the user from injury during biting. The pressure sensor between the outer shell 402 and the air connection tube 404 can detect the biting force. The structure and material of the air connection tube 404 can prevent the air connection tube 404 from undergoing large deformation when the occlusal device 4 is bitten, so as not to affect the normal use of the air tube.

[0030] The second sensor is mounted on the support plate 501, which is made of elastic silicone. The pressure value of the second sensor during use is recorded as B.

[0031] The controller includes a signal receiving device, a signal processing device, and a control device. The signal receiving device is linearly connected to the first sensor and the second sensor and is used to receive the numerical signals from the sensors. The signal processing device is used to process the relationship between the sensor numerical signals and the inflation amount of the inflation switch 2. The control device controls the inflation of the inflation switch 2 and the inflation control device 7 by receiving the signal processing device's model number.

[0032] The inflation amount for inflation switch 2 is "C1=[B / A2-A1]C2"; Wherein, B is the pressure value when the second sensor is in use, A2 is the pressure value when the first sensor is in use, A1 is the pressure value of the first pressure sensor when the biting device 4 is inflated to 85%, C2 is the inflation amount when the biting device 4 is inflated to 85%, and C1 is the inflation amount of the inflation switch 2 during use.
