Description

Technical Field

[0001] The invention belongs to the technical field of cardiopulmonary rehabilitation training, in particular to a patient cardiopulmonary exercise rehabilitation training device. Background Art

[0002] Cardiopulmonary function refers to the ability of the human heart to pump blood and the lungs to inhale oxygen. The ability of both directly affects the activities of organs and muscles throughout the body, so it is very important. Oxygen is inhaled by the lungs, so the size of the lung capacity and the number of activities are very important; and the heart is responsible for sending oxygen to various organs and parts through the blood circulation system, so the strength of the heartbeat will affect the blood flow. Therefore, cardiopulmonary function includes the blood circulation speed, the strength of the heartbeat, the capacity and number of lung beats.

[0003] A cardiopulmonary exercise rehabilitation training device for patient care with publication number CN213884652U is provided. The device includes an oxygen pump, a telescopic hose, an oxygen cylinder, an air inlet pipe, a filter and a filter net. The inside of the ventilator is provided with an oxygen pump, and the inside of the connecting plate is provided with a filter. Under the action of the oxygen pump, oxygen is drawn from the oxygen cylinder through the intake pipe to provide oxygen for patients doing rehabilitation exercises, thereby avoiding wound deterioration caused by breathing polluted air, thereby facilitating the use of the patients.

[0004] When the patient is training, the breathing mask used for oxygen supply will move with the patient's head, thereby swinging the breathing mask. Although the telescopic hose can be adjusted in length, because the telescopic hose is passively stretched, the patient's face and the breathing mask may be briefly separated, causing the patient's breathing mask to shift and accompanied by oxygen leakage, which will also give the patient a sense of restraint, so improvements are needed.

[0008] Furthermore, the deflection component includes a joint ball, and through openings are evenly opened at the axis center of the inner cavity of the joint ball. The joint ball is a hollow ball shell filled with a filter element. An internal hard tube is fixedly connected to the axis center on the left side of the outer surface of the joint ball. The internal hard tube is a small section of hollow hard tube shell, which will passively deflect as the joint ball rotates. Extension rods are evenly arranged on the outer surface of the internal hard tube, and a rubber inner sleeve is fixedly connected to the left end of the internal hard tube. A pressing inner ring is arranged on the outer surface of the extension rod.

[0009] Furthermore, the outer surface of the joint ball is rotatably connected to the right end of the inner cavity of the sliding long cylinder, and an arc groove structure for clamping the joint ball is provided at the axis of the right end of the sliding long cylinder to ensure that the joint ball can rotate freely and will not fall off the sliding long cylinder. The left end of the output rubber tube is fixedly connected to the axis of the right side of the outer surface of the joint ball, and the outer surface of the pressing inner ring is fixedly connected to the right side of the inner cavity of the sliding long cylinder through the annular groove. The middle part of the outer surface of the outer cylinder shell is fixedly connected to the top of the inner wall of the limit frame, and the left and right sides of the outer surface of the sliding long cylinder are both slidably connected to the axis of the inner wall of the outer cylinder shell, and the outer surface of the rubber inner sleeve is fixedly connected to the axis of the inner wall of the sliding long cylinder.

[0010] Furthermore, spring inner cylinders are symmetrically arranged on the left and right sides of the inner wall of the outer cylinder shell, a side pressure cylinder is arranged on the side of the spring inner cylinder away from the sleeve bearing ring, and a force push rod is evenly arranged on the side of the inner cavity of the side pressure cylinder close to the spring inner cylinder, and the end of the force push rod away from the side pressure cylinder and the end of the spring inner cylinder are mutually squeezed, and when the sliding long cylinder slides directionally along the inner wall of the outer cylinder shell, it will press the force push rod on one side of the sliding direction by pushing the spring inner cylinder. There are two spring inner cylinders, the outer surface of the spring inner cylinder is slidably connected to the inner wall of the outer cylinder shell, the outer surface of the sleeve bearing ring is fixedly connected to the end of the spring inner cylinder away from the force push rod, and the outer surface of the sleeve bearing ring is slidably connected to the inner wall of the outer cylinder shell through an auxiliary ball.

[0011] Further, the internal pressure device includes a plug-in shell, and the two ends of the inner wall of the plug-in shell are symmetrically provided with bending rotating tubes, and the end of the bending rotating tube away from the plug-in shell is fixedly connected with a docking baffle, and the side of the outer surface of the docking baffle away from the bending rotating tube is fixedly connected with a pressure-sensitive baffle.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the patient is training, the breathing mask for oxygen supply will move with the patient's head, thereby swinging the breathing mask. Although the telescopic hose can be adjusted in length, because the telescopic hose is passively stretched, the patient's face and the breathing mask may be briefly separated at this time, which in turn causes the patient's breathing mask to shift and accompanied by oxygen leakage. The device adds a deflection component at the joint position of the output rubber tube. Through the stretchable sliding cylinder and the widely rotatable joint ball, the restriction of the breathing mask on the patient's head is reduced, and the breathing mask is ensured to always fit the patient's face, thereby avoiding the problem of oxygen leakage from the breathing mask.

[0014] 2. The oxygen of the device is transported to the inside of the adapter mask through the through-hole of the joint rotating ball. In order to avoid the problem of oxygen leakage from the gap between the joint rotating ball and the sliding long cylinder, a built-in hard tube and a rubber inner sleeve are arranged inside the sliding long cylinder to guide the oxygen to enter the joint rotating ball only, and prevent the oxygen from flowing out through the gap between the joint rotating ball and the sliding long cylinder, thereby effectively reducing the phenomenon of oxygen waste, while ensuring the safety and reliability of the device.

[0015] 3. A plurality of feedback devices are arranged inside the device. The deflection amplitude of the joint rotating ball is fed back by the squeezing force exerted by pressing the inner wall of the inner ring, and the moving distance of the sliding tube is fed back by the pressing force of the force-bearing push rod, so as to judge the intensity of the patient's exercise, and then appropriately adjust the oxygen supply according to the intensity of the patient's exercise. The device with structural changes can automatically recover and return to its initial state after the patient has finished using it.

[0016] 4. When supplying oxygen, oxygen will be delivered to the breathing mask through the channel of the sliding long cylinder axis. Since the left end of the sealed tube needs to be continuously pressurized to transport oxygen from left to right, there is a certain pressure in the sliding long cylinder axis channel. The pressure-sensitive baffle can measure the real-time pressure of the sliding long cylinder axis channel according to the bent rotating tube connected to the plug-in shell, and then select the pressure adjustment work according to the patient's breathing intensity, so as to avoid the patient's intense breathing and insufficient oxygen supply, which may cause the patient to suffer from hypoxia during training.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a patient cardiopulmonary exercise rehabilitation training device, comprising a control panel 1, a pressure control bottom cylinder 2 is fixedly connected to the right side of the control panel 1, an oxygen supply bottle 3 is fixedly connected to the top of the pressure control bottom cylinder 2, a limiting frame 4 is fixedly connected to the right side of the outer surface of the pressure control bottom cylinder 2, a drainage device 5 is arranged on the top of the limiting frame 4, and the drainage device 5 can directly output the oxygen inside the oxygen supply bottle 3 to the outside; the drainage device 5 comprises an outer cylinder shell 51, a connecting device 7 is slidably connected inside the outer cylinder shell 51, and a breathing mask 6 is arranged on the right end of the connecting device 7;

[0027] The connecting device 7 includes a sliding cylinder 71, a sleeve bearing ring 72 is fixedly connected to the middle of the outer surface of the sliding cylinder 71, and the inner cavity of the sleeve bearing ring 72 is evenly provided with auxiliary balls 73. A sealing tube 74 is fixedly connected to the left side of the inner cavity of the sliding cylinder 71, and a deflection component 9 is provided on the right side of the inner cavity of the sliding cylinder 71. The deflection component 9 can flexibly rotate with the breathing mask 6 component. An internal pressure device 8 is provided in the middle of the outer surface of the sliding cylinder 71, and the internal pressure device 8 can limit the movement of the sliding cylinder 71.

[0028] The breathing mask 6 includes an output rubber tube 61, and the right end of the output rubber tube 61 is fixedly connected to an adapting mask 62. The adapting mask 62 can be replaced at any time to facilitate disinfection work. The outer surface of the adapting mask 62 is symmetrically provided with belt reels 63 on both sides, and the inner sliding connection of the left belt reel 63 is a limiting belt 64, and the inner sliding connection of the right belt reel 63 is an extension plug belt 65. The right end of the limiting belt 64 is fixedly connected to a docking plate 66. Through the plug-in action of the docking plate 66 and the extension plug belt 65, the adapting mask 62 can be tied to the patient's head.

[0029] The deflection component 9 includes a joint rotating ball 93, and a through hole 94 is evenly opened at the axis center of the inner cavity of the joint rotating ball 93. The joint rotating ball 93 is a hollow ball shell filled with a filter element. An internal hard tube 91 is fixedly connected to the axis center on the left side of the outer surface of the joint rotating ball 93. The internal hard tube 91 is a small section of hollow hard tube shell, which will passively deflect with the rotation of the joint rotating ball 93. The outer surface of the internal hard tube 91 is evenly provided with an extension support rod 95, and the left end of the internal hard tube 91 is fixedly connected to a rubber inner sleeve 92, and the outer surface of the extension support rod 95 is provided with a pressing inner ring 96.

[0030] The outer surface of the joint ball 93 is rotatably connected to the right end of the inner cavity of the sliding long cylinder 71. An arc groove structure for clamping the joint ball 93 is provided at the axis of the right end of the sliding long cylinder 71 to ensure that the joint ball 93 can rotate freely and will not be separated from the sliding long cylinder 71. The left end of the output rubber tube 61 is fixedly connected to the axis of the right side of the outer surface of the joint ball 93. The outer surface of the pressing inner ring 96 is fixedly connected to the right side of the inner cavity of the sliding long cylinder 71 through the annular groove. The middle part of the outer surface of the outer cylinder shell 51 is fixedly connected to the top of the inner wall of the limit frame 4. The left and right sides of the outer surface of the sliding long cylinder 71 are both slidably connected to the axis of the inner wall of the outer cylinder shell 51. The outer surface of the rubber inner sleeve 92 is fixedly connected to the axis of the inner wall of the sliding long cylinder 71.

[0031] The patient buckles the disinfected adaptable mask 62 around the mouth and nose, then loosens the limiting belt 64 and the extension strap 65 through the belt reel 63, ties them around his head, inserts the extension strap 65 into the docking plug plate 66, adjusts the tightness of the strap, and uses the belt reels 63 on both sides to fix the straps on both sides to complete the preparation work.

[0032] When the patient is exercising in situ, the device starts the pressure-controlled bottom cylinder 2 through the control panel 1, pressurizes the oxygen supply bottle 3 according to the patient's heart rate, controls the oxygen supply, and then delivers the oxygen to the inside of the breathing mask 6 through the drainage device 5 and the output rubber tube 61 for the patient to breathe. Since the patient's head moves during exercise, the deflection component 9 is pulled by the output rubber tube 61 of the breathing mask 6. At this time, the internal sliding cylinder 71 will slide out from the inside of the sliding cylinder 71 under the traction of the output rubber tube 61. As the patient's head moves, the bottom end of the output rubber tube 61 will also drive the joint rotating ball 93 to deflect around the front end of the sliding cylinder 71. Since the bottom end of the output rubber tube 61 always wraps the through-opening 94 of the joint rotating ball 93, no matter how the joint rotating ball 93 deflects, oxygen is always delivered to the inside of the breathing mask 6 through the through-opening 94 and the output rubber tube 61.

[0033] Oxygen flows from left to right through the axis of the sliding cylinder 71, and enters the through-hole 94 of the joint rotating ball 93 under the guidance of the built-in hard tube 91. When the joint rotating ball 93 deflects with the output rubber tube 61, its built-in hard tube 91 will also deflect accordingly with the joint rotating ball 93, but the rubber inner sleeve 92 always separates the area between the built-in hard tube 91 and the sliding cylinder 71, ensuring that oxygen will not escape through the gap between the joint rotating ball 93 and the sliding cylinder 71.

[0034] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of the first embodiment, spring inner cylinders 52 are symmetrically arranged on the left and right sides of the inner wall of the outer cylinder shell 51, a side pressure cylinder 53 is arranged on the side of the spring inner cylinder 52 away from the sleeve bearing ring 72, and a force push rod 54 is evenly arranged on the side of the inner cavity of the side pressure cylinder 53 close to the spring inner cylinder 52, and the end of the force push rod 54 away from the side pressure cylinder 53 and the end of the spring inner cylinder 52 are pressed against each other, and when the sliding long cylinder 71 slides along the inner wall of the outer cylinder shell 51 in a directional manner, it will press the force push rod 54 on one side of the sliding direction by pushing the spring inner cylinder 52. There are two spring inner cylinders 52, the outer surface of the spring inner cylinder 52 is slidably connected to the inner wall of the outer cylinder shell 51, the outer surface of the sleeve bearing ring 72 is fixedly connected to the end of the spring inner cylinder 52 away from the force push rod 54, and the outer surface of the sleeve bearing ring 72 is slidably connected to the inner wall of the outer cylinder shell 51 through the auxiliary ball 73.

[0035] The internal pressure device 8 comprises a plug-in housing 81, and two ends of the inner wall of the plug-in housing 81 are symmetrically provided with bending rotating tubes 82, and one end of the bending rotating tube 82 away from the plug-in housing 81 is fixedly connected with a docking baffle 83, and one side of the outer surface of the docking baffle 83 away from the bending rotating tube 82 is fixedly connected with a pressure-sensitive baffle 84. There are six plug-in housings 81, and the bottom end of the plug-in housing 81 is fixedly connected to the middle of the inner wall of the sliding long cylinder 71 through a plug-in groove, and the bottom end of the plug-in housing 81 extends to the axis of the sliding long cylinder 71, and there are two docking baffles 83, and the outer surface of the docking baffle 83 is fixedly connected to the inner wall of the sliding long cylinder 71. One end of the bending rotating tube 82 away from the plug-in housing 81 is fixedly connected to the inner cavity of the pressure-sensitive baffle 84 through a docking interface, and one end of the bending rotating tube 82 away from the pressure-sensitive baffle 84 is fixedly connected to the inner cavity of the plug-in housing 81 through a plug-in interface.

[0036] When the built-in hard tube 91 deflects, the expansion support rod 95 on its outer surface will squeeze the inner wall of the pressing inner ring 96, thereby feeding back the deflection amplitude of the joint rotating ball 93, and then appropriately adjusting the oxygen supply according to the intensity of the patient's exercise.

[0037] When the sliding cylinder 71 is pulled out from the outer cylinder shell 51, the sleeve bearing ring 72 on its outer surface will squeeze the spring inner cylinder 52 at the corresponding position, thereby triggering the force-bearing push rod 54 on the outer cylinder shell 51. On the one hand, it can buffer the movement of the sliding cylinder 71, and on the other hand, the moving distance of the sliding cylinder 71 can be estimated according to the pressing force of the force-bearing push rod 54 of the sliding cylinder 71.

[0038] When supplying oxygen, oxygen will be delivered to the breathing mask 6 through the channel of the axis of the sliding long cylinder 71. Since the left end of the sealing tube 74 needs to be continuously pressurized to transport oxygen from left to right, there is a certain pressure in the axis channel of the sliding long cylinder 71. The pressure-sensitive baffle 84 can measure the real-time pressure of the axis channel of the sliding long cylinder 71 according to the bending rotating tube 82 connected to the plug-in shell 81, and then select the pressure adjustment work according to the patient's breathing intensity, so as to avoid the patient's intense breathing and insufficient oxygen supply, which will cause the patient to suffer from hypoxia during training.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
