Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical articles, and in particular to a simple breathing balloon. Background Art
[0002] The simple breathing bag is a portable medical device used to provide manual ventilation for patients with no spontaneous breathing or insufficient breathing in emergency situations. It can be operated without power and is suitable for cardiopulmonary resuscitation, patient transfer or temporary replacement when a ventilator fails.
[0003] Simple breathing balloon structure Figure 1 and Figure 2 As shown, the device comprises an elastic airbag, an output tube, and a face mask. The output tube is connected to the front end of the elastic airbag, which is then connected to the face mask. The rear end of the elastic airbag is equipped with an inlet check valve and other valves. The output tube is equipped with an exhaust check valve, an exhalation mechanism, and a pressure-mounted valve. To use the simple breathing balloon, the patient's mouth and nose are covered with a face mask and the elastic airbag is squeezed, forcing the gas inside into the output tube. The gas pressure opens the exhaust check valve, allowing gas to enter the face mask and then be squeezed into the patient's airway. The elastic airbag is then released, closing the exhaust check valve and opening the inlet check valve, allowing gas to be drawn into the airbag. Simultaneously, the exhalation mechanism opens, expelling the patient's exhaled gas. This process is repeated to assist the patient in breathing. The pressure-mounted valve prevents gas from being discharged when the gas pressure is too high, thus preventing excessive pressure on the patient's lungs.
[0004] The frequency of squeezing and releasing the Easy Breathing Balloon is set to 12 times per minute for adults. This means each squeezing and releasing should take 5 seconds, 2 seconds for squeezing, and 3 seconds for releasing, to match the patient's breathing rhythm. Currently, this squeezing and releasing timing is manually controlled by medical staff, who often silently count to keep track, making it difficult to accurately control the timing. This is further complicated by prolonged use or interference from other factors. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a simple breathing balloon which can automatically ensure the patient's inhalation and exhalation rhythm.
[0006] The technical solution adopted to solve the above technical problems is as follows: the simple breathing balloon includes an output tube, which includes an output horizontal tube and an output vertical tube; and also includes a timing drive device, a control device and a first spring;
[0007] The output vertical pipe includes a vertical pipe body and a lower horizontal plate. The vertical pipe body has a vertical pipe air hole. The lower horizontal plate is located in the vertical pipe body and connected to the vertical pipe body. The lower horizontal plate is located above the vertical pipe air hole and has a horizontal plate air hole.
[0008] The control device includes a valve plate, a valve stem, a connecting rod and a closing ring. The valve plate is located above the lower horizontal plate. The closing ring is located below the lower horizontal plate and cooperates with the vertical tube body. The connecting rod passes through the lower horizontal plate and is connected to the closing ring. The valve stem is vertically arranged above the valve plate and connected to the valve plate.
[0009] The first spring pushes up the valve stem; the timing drive device is located above the output pipe and is connected to the output pipe, and the timing drive device can automatically drive the valve stem to overcome the resistance of the first spring and move downward, thereby driving the valve plate and the closing ring to move downward; when the valve plate and the closing ring are in a high position, the gas in the vertical tube body can flow from the upper horizontal plate to the lower part through the horizontal plate air holes, and the closing ring closes the vertical tube air holes; when the valve plate and the closing ring are in a low position, the valve plate closes the horizontal plate air holes, and the closing ring and the vertical tube air holes are staggered.
[0010] Furthermore, within one movement cycle of the valve plate and the sealing ring, the time the valve plate and the sealing ring are located at the high position is 2 seconds, and the time the valve plate and the sealing ring are located at the low position is 3 seconds.
[0011] Furthermore, the timing drive device includes a driving cam, the driving cam includes a large-diameter wheel edge surface and a small-diameter wheel edge surface, and the large-diameter wheel edge surface and the small-diameter wheel edge surface have a smooth transition; the first spring causes the upper end of the valve stem to press against the wheel edge surface of the driving cam; when the upper end of the valve stem presses against the small-diameter wheel edge surface, the valve plate and the closing ring are located in a high position; when the upper end of the valve stem presses against the large-diameter wheel edge surface, the valve plate and the closing ring are located in a low position.
[0012] Furthermore, the timing drive device includes a housing, a mainspring, a first large gear, a first wheel group, a second wheel group, an escapement mechanism and a ratchet mechanism; the first large gear is mounted on the housing and connected to the mainspring; the first wheel group is mounted on the housing, the first wheel group includes a first small gear and a second large gear arranged coaxially, and the first small gear is meshed with the first large gear; the second wheel group is mounted on the housing, the second wheel group includes a second small gear coaxial with and connected to the driving cam, and the second small gear is meshed with the second large gear; the escapement mechanism is mounted on the housing, the escapement wheel of the escapement mechanism is coaxially arranged with the driving cam, and the escapement wheel is connected to the second wheel group through the ratchet mechanism.
[0013] Furthermore, the output vertical pipe includes an upper horizontal plate, which is located above the valve plate; the valve stem passes through the upper horizontal plate, and the valve stem has a valve stem flange located above the upper horizontal plate; the first spring is sleeved on the valve stem and is located between the upper horizontal plate and the valve stem flange.
[0014] Furthermore, a roller is provided on the top end of the valve stem, and the roller presses against the wheel edge surface of the driving cam.
[0015] Furthermore, the timing drive device includes a brake structure, which can stop the timing drive device from working.
[0016] Furthermore, the brake structure includes a first friction wheel, a second friction wheel, a guide rod, a second spring and a tightening screw. The first friction wheel is coaxially arranged and connected to the escapement wheel, the guide rod is coaxially arranged with the first friction wheel and connected to the housing, the second friction wheel is sleeved on the guide rod and cooperates with the guide rod, the second spring is sleeved on the guide rod and keeps the second friction wheel away from the first friction wheel, and the tightening screw is threadedly connected to the housing, and the tightening screw can push the second friction wheel toward the first friction wheel.
[0017] The beneficial effect of the present invention is that when the present invention is used, the timing drive device is turned on, and the timing drive device drives the valve stem according to the beat of the common breathing balloon. Figure 6 As shown, the timing drive device does not drive the valve stem to move downward. Under the action of the spring, the valve stem, valve plate and closing ring are in a high position. The valve plate does not close the air holes in the horizontal plate, and the closing ring closes the air holes in the vertical tube. Since the air holes in the horizontal plate are open, the elastic airbag can be flattened, and the elastic airbag is slowly squeezed. The gas inside the elastic airbag enters the mask through the air holes in the horizontal plate and then enters the patient's airway, thereby assisting the patient in breathing.
[0018] When the time comes, if Figure 3 As shown, the timing drive device drives the valve stem downward to overcome the resistance of the first spring. The valve stem, valve plate, and sealing ring are in a low position, the valve plate seals the air holes in the transverse plate, and the sealing ring is offset from the air holes in the vertical tube. At this time, because the valve plate seals the air holes in the transverse plate, the gas in the elastic airbag cannot be squeezed out, that is, the elastic airbag cannot be squeezed smaller or the pressure mounting valve is open. The operator can sense this and release the elastic airbag, which rebounds and quickly fully inflates from its rear end due to inhalation. At the same time, because the sealing ring is offset from the air holes in the vertical tube, the patient exhales, and gas is discharged from the air holes in the vertical tube.
[0019] After the operator completely releases the elastic airbag, he / she applies a small squeeze force. Figure 3 In the state shown (valve plate and closing ring are in the low position), the elastic airbag cannot be squeezed. Figure 6 The elastic airbag can be squeezed smaller again only when the valve plate and the closing ring are in the high position.
[0020] As can be seen, the elastic airbag of the present invention begins squeezing when the airbag inflates. It ends squeezing and releases when the airbag can no longer be squeezed (or the pressure-mounted valve opens). This eliminates the need for manual timing to control squeezing and releasing the airbag, ensuring accurate timing of the breathing bag's assisted inhalation and exhalation.

DETAILED DESCRIPTION
[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] The simple breathing balloon includes an output tube 1, including an output transverse tube 12 and an output vertical tube 11; it also includes a timing drive device 3, a control device 2 and a first spring 4; the output vertical tube 11 includes a vertical tube body 111 and a lower transverse plate 112, the vertical tube body 111 has a vertical tube air hole 1111, the lower transverse plate 112 is located in the vertical tube body 111 and is connected to the vertical tube body 111, the lower transverse plate 112 is located above the vertical tube air hole 1111, and the lower transverse plate 112 has a transverse plate air hole 1121; the control device 2 includes a valve plate 21, a valve stem 24, a connecting rod 22 and a closing ring 23, the valve plate 21 is located above the lower transverse plate 112, the closing ring 23 is located below the lower transverse plate 112 and cooperates with the vertical tube body 111, and the connecting rod 22 passes through the lower transverse plate 112 and is connected to the closed ring 23, the valve stem 24 is vertically arranged above the valve plate 21 and is connected to the valve plate 21; the first spring 4 pushes the valve stem 24; the timing drive device 3 is located above the output pipe 1 and is connected to the output pipe 1, the timing drive device 3 can automatically drive the valve stem 24 to overcome the resistance of the first spring 4 and move downward, thereby driving the valve plate 21 and the closed ring 23 to move downward; when the valve plate 21 and the closed ring 23 are in a high position, the gas in the vertical tube body 111 can flow from the top of the upper horizontal plate 113 to the bottom through the horizontal plate air holes 1121, and the closed ring 23 closes the vertical tube air holes 1111; when the valve plate 21 and the closed ring 23 are in a low position, the valve plate 21 closes the horizontal plate air holes 1121, and the closed ring 23 is staggered with the vertical tube air holes 1111.
[0030] The other structures of the present invention are the same as those of existing devices, namely, the simple breathing balloon still includes the elastic airbag 5, the mask 6, the pressure relief valve 7, and the air inlet check valve. The output tube 1 is connected to the front end of the elastic airbag 5, the mask 6 is connected to the lower end of the output tube 1, the air inlet check valve is located at the rear end of the elastic airbag 5, and the pressure relief valve 7 is located on the output tube 1.
[0031] When the present invention is used, the timing drive device 3 is turned on, and the timing drive device 3 drives the valve stem 22 according to the beat of the common breathing balloon. Figure 6 As shown, the timing drive device 3 does not drive the valve stem 24 to move downward. Under the action of the first spring 4, the valve stem 24, the valve plate 21 and the closing ring 23 are in a high position, the valve plate 21 does not close the transverse plate air hole 1121, and the closing ring 23 closes the vertical tube air hole 1111; since the transverse plate air hole 1121 is open, the elastic airbag 5 can be flattened, and the elastic airbag 5 is slowly squeezed. The gas inside the elastic airbag 5 enters the mask 6 through the transverse plate air hole 1121, and then enters the patient's airway, thereby assisting the patient in breathing.
[0032] When the time comes, if Figure 3As shown, the timing drive device 3 drives the valve stem 24 to overcome the resistance of the first spring 4 and move downward. The valve stem 24, valve plate 21, and closed ring 23 are in a low position. The valve plate 21 seals the cross plate air hole 1121, and the closed ring 23 is staggered with the vertical tube air hole 1111. At this time, because the valve plate 21 seals the cross plate air hole 1121, the gas in the elastic airbag 5 cannot be squeezed out, that is, the elastic airbag 5 cannot be squeezed smaller, or the pressure mounting valve 7 is opened. The operator can sense this and release the elastic airbag 5 upon sensing it. The elastic airbag 5 rebounds and quickly fully inflates from its rear end by inhaling air. At the same time, because the closed ring 23 is staggered with the vertical tube air hole 1111, the patient exhales and the gas is discharged from the vertical tube air hole 1111.
[0033] After the operator completely releases the elastic airbag 5, he or she applies a small squeezing force. At this time, the simple breathing balloon is still in the Figure 3 In the state shown (valve plate 21 and closing ring 23 are at the low position), the elastic airbag 5 cannot be squeezed (or the pressure mounting valve 7 is open). Figure 6 Only in the state shown (the valve plate 21 and the closing ring 23 are at the high position) can the elastic airbag 5 be squeezed smaller again.
[0034] As can be seen, the elastic airbag 5 of the present invention begins squeezing when it inflates. It ends squeezing and releases when it can no longer be squeezed or the pressure-mounted valve opens. This eliminates the need for manual timing to control the squeezing and releasing of the elastic airbag 5, ensuring accurate timing of the breathing balloon's assisted inhalation and exhalation.
[0035] According to the existing breathing bag squeezing time requirements, during one movement cycle of the valve plate 21 and the closing ring 23, the time the valve plate 21 and the closing ring 23 are in the high position is 2 seconds, and the time the valve plate 21 and the closing ring 23 are in the low position is 3 seconds.
[0036] The specific structure of the timing drive device 3 driving the valve stem 24 to move downward can be as follows: the timing drive device 3 includes a driving cam 352, and the driving cam 352 includes a large-diameter wheel edge surface 3522 and a small-diameter wheel edge surface 3521, and the large-diameter wheel edge surface 3522 and the small-diameter wheel edge surface 3521 have a smooth transition; the first spring 4 makes the upper end of the valve stem 24 press against the wheel edge surface of the driving cam 352; when the upper end of the valve stem 24 presses against the small-diameter wheel edge surface 3521, the valve plate 21 and the closing ring 23 are in a high position; when the upper end of the valve stem 24 presses against the large-diameter wheel edge surface 3522, the valve plate 21 and the closing ring 23 are in a low position. The time when the valve plate 21 and the sealing ring 23 are in the high position is 2 seconds, and the time when the valve plate 21 and the sealing ring 23 are in the low position is 3 seconds. The theoretical value of the central angle of the large-diameter wheel edge surface 3522 is 216°. Due to the presence of the transition surface, the actual value is slightly less than 216°. The theoretical value of the central angle of the small-diameter wheel edge surface 3521 is 144°. Due to the presence of the transition surface, the actual value is slightly less than 144°.
[0037] In this way, the driving cam 352 only needs to rotate at a constant speed or rotate intermittently at a constant speed, and the time for one rotation is five seconds. The timing drive device 3 can drive the valve stem 24 to move downward as required, and at the same time make space when the valve stem 24 needs to move upward, and the first spring 4 drives the valve stem 24 to move upward.
[0038] The power for driving the cam 352 to rotate can come from a motor, but in this case a plug needs to be provided to power the motor, affecting the portability of the simple breathing balloon; or a rechargeable battery needs to be provided, which significantly increases the weight of the simple breathing balloon. The preferred driving cam 352 of the present invention is driven in the following manner: the timing drive device 3 includes a housing 31, a mainspring 32, a first large gear 33, a first wheel group 34, a second wheel group 35, an escapement mechanism 37 and a ratchet mechanism 36; the first large gear 33 is mounted on the housing 31 and is connected to the mainspring 32; the first wheel group 34 is mounted on the housing 31, and the first wheel group 34 includes a first small gear 341 and a second large gear 342 arranged coaxially, and the first small gear 341 is engaged with the first large gear 33; the second wheel group 35 is mounted on the housing 31, and the second wheel group 35 includes a second small gear 351 that is coaxial with and connected to the driving cam 352, and the second small gear 351 is engaged with the second large gear 342; the escapement mechanism 37 is mounted on the housing 31, and the escapement wheel 371 of the escapement mechanism 37 is coaxially arranged with the driving cam 352, and the escapement wheel 371 is connected to the second wheel group 35 through the ratchet mechanism 36.
[0039] The above structure draws on some of the principles of mechanical timepieces. Mainspring 32 provides power. Escapement 37 is a conventional mechanism, comprising an escape wheel 371, a pallet fork 372, and a balance wheel with a hairspring 373. In mechanical timepieces, escapements control the punctual and uniform intermittent rotation of various components. Similarly, in the present invention, escapement 37 controls the punctual and uniform intermittent rotation of drive cam 352, ensuring that the drive cam 352 completes one rotation in 5 seconds.
[0040] The meshing of the first large gear 33, the first small gear 341, the second large gear 342, and the second small gear 351 allows the mainspring 32 to unwind more slowly, thereby increasing the time it can be wound up. The ratchet mechanism 36 ensures that the escapement wheel 371 rotates when the second wheel set 35 rotates forward. Furthermore, the escapement wheel 371 does not affect the reverse rotation of the second wheel set 35, thus preventing the escapement wheel 371 from affecting the winding of the mainspring 32.
[0041] The driving cam 352 is driven in the above manner, does not need to be connected to electricity, is more convenient to use, and is smaller in size and lighter in weight than the method of using a motor and a battery.
[0042] The control device 2 has a more specific structure as follows: the output riser 11 includes an upper transverse plate 113, which is located above the valve plate 21; the valve stem 24 passes through the upper transverse plate 113 and has a valve stem flange 241 located above the upper transverse plate 113; the first spring 4 is sleeved on the valve stem 24 and located between the upper transverse plate 113 and the valve stem flange 241. To reduce friction between the valve stem 24 and the drive cam 352, a roller 242 is preferably provided at the top of the valve stem 24, which abuts against the wheel edge of the drive cam 352.
[0043] Furthermore, the timing drive device 3 of the present invention preferably includes a brake structure 38, which can stop the timing drive device 3. Specifically, the brake structure 38 includes a first friction wheel 381, a second friction wheel 382, a guide rod 384, a second spring 383, and a tightening screw 385. The first friction wheel 381 is coaxially arranged and connected to the escape wheel 371. The guide rod 384 is coaxially arranged with the first friction wheel 381 and connected to the housing 31. The second friction wheel 382 is mounted on the guide rod 384 and cooperates with the guide rod 384. The second spring 383 is mounted on the guide rod 384 and moves the second friction wheel 382 away from the first friction wheel 381. The tightening screw 385 is threadedly connected to the housing 31 and can push the second friction wheel 382 toward the first friction wheel 381.
[0044] Brake mechanism 38 stops timing drive 3 when the easy-breathing balloon is not in use, preventing unnecessary energy consumption from mainspring 32. Tightening locking screw 385, which forces second friction wheel 382 into contact with first friction wheel 381 and maintains a certain pressure, restricts rotation of escape wheel 371 and stops timing drive 3, thus preventing unnecessary energy consumption. Loosening locking screw 385 allows second spring 383 to separate second friction wheel 382 from first friction wheel 381, resuming timing drive 3 operation.
