Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a pulmonary hypertension treatment device. Background Art

[0002] Pulmonary hypertension is a serious circulatory disease, which is defined as the change of pulmonary vascular structure and (or) function caused by a variety of heterogeneous diseases and different pathogenesis. The ventilator is an auxiliary instrument for the treatment of pulmonary hypertension. By increasing the inhaled oxygen concentration and optimizing the ventilation / perfusion ratio, the ventilator can correct hypoxemia and reduce the pulmonary vasoconstriction caused by hypoxia, thereby indirectly alleviating the progression of pulmonary hypertension.

[0003] During the use of the existing ventilators, condensate will appear in the patient's inhalation tube. This is because when the air humidified and heated by the humidifying tank in the ventilator flows in the inhalation tube, due to the temperature difference between the inside and outside of the tube, water molecules will condense into water droplets, forming condensate. In addition to condensate, water droplets will also accumulate due to gravity at the bent or sagging parts of the inhalation tube. The generation of condensate will affect the normal use of the ventilator, may increase the risk of respiratory tract infection, and in severe cases, the condensate will flow back into the patient's lower respiratory tract, causing serious complications such as ventilator-associated pneumonia.

An extrusion assembly is installed inside the transparent cover 10 corresponding to the outer side of the hose 9. The number of the extrusion assemblies is two groups and they are symmetrically distributed. The extrusion assembly includes an extrusion block 28 that can move inside the transparent cover 10. A limiting rod 29 passes through the extrusion block 28. The extrusion block 28 is movably sleeved on the outer side of the limiting rod 29. Both ends of the limiting rod 29 are fixedly connected with positioning blocks 30. The positioning blocks 30 are fixedly connected to the transparent cover 10.

[0027] On one side of the two extrusion blocks 28 away from each other, a second spring 31 is movably abutted, and the second spring 31 is movably sleeved outside the limiting rod 29.

[0029] Embodiment 4: Please refer to Figure 2 、 Figure 7 , this embodiment further explains Embodiment 1. A locking component is installed between the rigid pipe 7 and the transparent cover 10. The locking component includes two socket seats 38 fixedly installed at the upper end of the transparent cover 10 and symmetrically distributed. A movable pin rod 39 penetrates through the inside of the socket seat 38. Hemispherical parts are arranged at both ends of the pin rod 39. A second limiting ring 40 is fixedly sleeved on the outside of the pin rod 39 corresponding to the inside of the socket seat 38. A third spring 41 is movably sleeved on the outside of the pin rod 39, and both ends of the third spring 41 are movably abutted against the socket seat 38 and the second limiting ring 40 respectively.

A retaining ring 42 is movably sleeved on the outside of the two pin rods 39, and the connection between the pin rod 39 and the retaining ring 42 is a sliding contact. When the solid parts of the pin rod 39 and the retaining ring 42 are abutted, the pin rod 39 cannot move inside the socket seat 38.

[0030] The upper end of the retaining ring 42 is provided with two symmetrically distributed notch portions 43. When the two notch portions 43 and the two pin rods 39 are located on the same horizontal line, the two pin rods 39 can move inside the socket 38. The outer side of the retaining ring 42 is fixedly sleeved with an anti-slip ring 44 near its lower end, and the outer side of the anti-slip ring 44 is movably sleeved with an annular seat 45, and the annular seat 45 is fixedly connected to the transparent cover 10. The retaining ring 42 is rotatably connected to the transparent cover 10 through the anti-slip ring 44 and the annular seat 45. The outer side of the fixed seat 6 is provided with two symmetrically distributed hemispherical grooves 46, and the hemispherical portion of the pin rod 39 is movably engaged with the fixed seat 6 through the hemispherical groove 46. When the pin rod 39 is embedded in the hemispherical groove 46 and one end is against the solid part of the retaining ring 42, the fixed seat 6 and the transparent cover 10 can be locked.

[0031] Working principle: When using the ventilator 1, the personnel install the positioning frame 15 on the bed board of the bed, and support the second catheter 4 located between the fixed sleeve 5 and the patient through the catheter bracket 47, so that the overall shape of the second catheter 4 is roughly V-shaped. During the operation of the ventilator 1, the condensed water generated in the second catheter 4 due to the temperature difference will enter the water collecting tank 12 through the hose 9. The condensed water in the second catheter 4 is collected by the water collecting tank 12, which can effectively prevent the condensed water in the second catheter 4 from affecting the normal operation of the ventilator 1 and endangering human health.

[0032] When it is necessary to drain the condensed water collected in the water collecting tank 12, the personnel rotate the adjusting bolt 18, and the adjusting bolt 18 rotates through the connecting plate 21 and the connecting rod 22 to drive the transparent cover 10 to move upward, so that the transparent cover 10 and the water collecting tank 12 are separated from each other. At this time, the personnel can remove the water collecting tank 12 from the socket 16 to drain the condensed water inside it. When it is necessary to sterilize the transparent cover 10, the personnel rotate the nut 27 to disengage it from the connecting rod 22. After that, the personnel can remove the transparent cover 10 and disinfect it for the reuse of the transparent cover 10, thereby effectively saving medical resources.

[0033] During the process of removing the water collecting tank 12 from the transparent cover 10, the two second springs 31 respectively drive the two extrusion blocks 28 to approach the hose 9, so that the two extrusion blocks 28 extrude the hose 9, thereby effectively avoiding the gas in the second conduit 4 being discharged through the hose 9 during the process of discharging the condensed water in the water collecting tank 12, which affects the gas flow rate entering the patient's body. When installing the water collecting tank 12, the operator inserts the water collecting tank 12 into the socket 16 through the two pin blocks 17, so that the water collecting tank 12 abuts against the positioning frame 15. Then, the adjusting bolt 18 is rotated in the reverse direction, so that the connecting plate 21 drives the transparent cover 10 to move downward through the connecting rod 22. During this process, the water collecting tank 12 drives the two ejector rods 32 and the two extrusion blocks 28 to move away from each other through the two guide rails 34 until the second sealing ring 14 abuts against the washer 13. (A certain length can be reserved for the hose 9 here, so that the hose 9 can be inserted into the water collecting tank 12 before the transparent cover 10 moves downward).

[0034] During the process of the two extrusion blocks 28 approaching each other, the two extrusion blocks 28 drive the sleeve 35 to move downward on the outer side of the hose 9 through the two inclined tie rods 36, so that the sleeve 35 moves out of the clamped area of the hose 9. When the two extrusion blocks 28 approach each other, the sleeve 35 will be driven by the inclined tie rod 36 to move upward to the clamped area of the hose 9. Since the inner diameter of the sleeve 35 is equal to the outer diameter of the hose 9, during the process of the sleeve 35 moving upward to the clamped area of the hose 9, it can assist the clamped area of the hose 9 to quickly recover, which is beneficial to the condensed water in the second conduit 4 to normally enter the water collecting tank 12 through the hose 9.

[0035] Before assembling the transparent cover 10 and the second conduit 4, the operator needs to confirm whether the two notch parts 43 and the two pin rods 39 are on the same horizontal line. Then, the operator passes the hose 9 and the rigid tube 7 through the transparent cover 10. During the insertion process, the operator needs to pay attention to the position of the limiting rib 8, so that the hemispherical part of the pin rod 39 can be directly stuck into the hemispherical card slot 46. Finally, the operator rotates the retaining ring 42 so that the pin rod 39 abuts against the solid part of the retaining ring 42, preventing the pin rod 39 from moving in the socket 38, so that the fixed seat 6 and the transparent cover 10 can be locked by the pin rod 39, preventing the transparent cover 10 from detaching from the second conduit 4 during the process of disassembling and assembling the water collecting tank 12.
