Description

Technical Field

[0001] The present invention relates to the field of ventilators, and more specifically, to a portable ventilator with a high degree of intelligence. Background Art

[0002] A ventilator is a device that can replace, control, or change a person's normal physiological respiration, increase pulmonary ventilation volume, improve respiratory function, reduce respiratory function consumption, and save the heart's reserve capacity. According to different working characteristics, ventilators can be divided into three categories: pressure-controlled type, volume-controlled type, and time-controlled type. In modern clinical medicine, as an effective means to artificially replace the autonomous ventilation function, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation, and occupy a very important position in the field of modern medicine.

[0003] Most traditional ventilators supply oxygen to patients by manually squeezing the airbag by medical staff, but this method is relatively labor-intensive for medical staff. Currently, it is usually achieved by automation to evenly squeeze the airbag, which can ensure continuous oxygen supply to patients.

[0004] However, the existing intelligent ventilators still have certain deficiencies in actual use. For example, when the ventilator loses power or the electrical components short-circuit, it cannot be used normally, and when squeezing the airbag, the degree of squeezing the airbag is inconvenient and cannot be adjusted according to the actual respiratory needs of the patient. Summary of the Invention

[0005] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a portable ventilator with a high degree of intelligence, which can squeeze the airbag to different degrees and can still supply oxygen to the patient when the servo motor fails to work properly.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] The present invention provides a highly intelligent portable ventilator, which includes a housing and a housing cover rotatably arranged on one side of the housing. A handle is fixedly arranged in the middle of the top end of the housing cover. A placement groove is arranged on one side inside the housing, and an airbag is placed in the placement groove. Both ends of the airbag are fixedly provided with connection components, and the connection components are arranged in semi-circular grooves opened on the housing and the housing cover. A push block in an arc convex shape is arranged on one side of the airbag inside the housing. A smart push component for pushing the position of the push block is arranged on one side of the push block. A hand-crank component for moving the push block is arranged on the side of the smart push component away from the push block. One end of the hand-crank component passes through the housing and is placed outside the housing. A travel switch is arranged on one side of the housing where the smart push component is located. An adjustment component for adjusting the position of the travel switch is arranged at the bottom of the travel switch. A trigger component corresponding to the travel switch is arranged on the smart push component. When the driving motor works, the position of the travel switch can be adjusted. When the servo motor works to drive the slide to move, the block can be driven to move at the same time. When the elastic pad on the block contacts the travel switch, at this time, the servo motor rotates in the reverse direction to drive the slide to move in the opposite direction. By adjusting the position of the travel switch, the moving distance of the slide can be adjusted, and further, the moving distance of the push block can be adjusted, so as to realize different degrees of extrusion of the airbag. When the servo motor cannot work properly, the crank can be rotated to drive the semi-gear to rotate, and the rotation of the semi-gear can drive the slide bar to move. When the slide bar contacts the slide, the push block can be driven to move. Therefore, even when the servo motor cannot work properly, oxygen supply and respiration for the patient can still be realized.

[0008] In a preferred technical solution of the present invention, the connection component includes a cylindrical fixed block. The fixed block is fixedly arranged on one side of the airbag, and an annular limiting card slot is opened on the outer wall of the fixed block. The fixed block is clamped in the semi-circular groove through the cooperation of the limiting card slot, and a connecting column is inserted into the inside of the semi-circular groove on the housing. A connecting groove matched with the connecting column is opened in the limiting card slot. Through the cooperation of the connecting column and the connecting groove, the limiting card slot is clamped and connected with the semi-circular groove. When the housing cover is closed, under the interaction of the two semi-circular grooves, the position of the airbag can be limited and fixed, and it is not necessary to install and fix the airbag, and it is also relatively convenient to disassemble the airbag.

[0009] In a preferred technical solution of the present invention, the connecting column is arranged in a circular cavity opened inside the housing, and a circular blocking block is fixedly arranged on the outside of the connecting column. A tightening spring is sleeved on the connecting column at the bottom of the blocking block in a matching manner. Both ends of the tightening spring are fixedly connected with the blocking block and the inner wall of the circular cavity respectively. Through the elastic action of the tightening spring, the stability of the clamping connection between the limiting card slot and the semi-circular groove can be improved.

[0010] In a preferred technical solution of the present invention, the intelligent pushing component includes a mounting base, the mounting base is fixedly arranged in the housing through fixing screws, and a sliding seat is arranged at the top end of the mounting base. One end of the sliding seat is fixedly connected to a pushing block. In the middle of the bottom end of the sliding seat, a limiting slider in an inverted T shape is fixedly arranged. The limiting slider is slidably arranged in a limiting sliding groove opened at the top end of the mounting base in a matching manner. A first rack is arranged at the top end of the sliding seat, a driving gear is meshed with the top of the first rack, and a servo motor for driving the driving gear is arranged on one side of the driving gear. When the servo motor works, it drives the first rack to move. The movement of the first rack can drive the pushing block to move. Through the pushing block, the airbag can be squeezed. By the matching sliding of the limiting slider and the limiting sliding groove, the stability of the position of the pushing block during movement can be improved.

[0011] In a preferred technical solution of the present invention, the hand-cranking component includes a movable frame. Slide bars are fixedly arranged on both sides of the movable frame. One of the slide bars is located on one side of the sliding seat. And limiting plates are slidably arranged on the outer parts of the two slide bars in a matching manner. The same limiting seat is fixedly connected to one side of the two limiting plates. The bottom end of the limiting seat is fixedly connected to the housing. By providing the limiting seat and the limiting plates, the position of the movable frame can be limited, so that the movable frame can only move horizontally along the slide bars.

[0012] In a preferred technical solution of the present invention, second racks are arranged on both the top end face and the bottom end face inside the movable frame. A turntable is arranged between the two second racks. A half gear is arranged on the outer part of the turntable. The half gear is meshed with both of the two second racks. A rotating shaft is fixedly arranged at the axis center of the turntable. One end of the rotating shaft passes through the housing and is fixedly provided with a hand crank. A flexible rubber sleeve is sleeved on the hand crank in a matching manner. Rotating the hand crank drives the half gear to rotate. When the half gear meshes with one of the second racks, it will push the movable frame to move. When the movable frame moves to the maximum distance, and then the half gear continues to rotate, the half gear will mesh with the other second rack. At this time, the second rack will drive the movable frame to move in the opposite direction. Therefore, when the hand crank is continuously rotated, the movable frame can be driven to move reciprocally. The movement of the movable frame can further drive the two slide bars to move reciprocally. Through the slide bars, the pushing block can be pushed.

[0013] In a preferred technical solution of the present invention, the adjusting assembly includes a connecting block. The travel switch is arranged on one side of the connecting block, and a fixing column is inserted at the bottom end of the connecting block. A sliding table is fixedly arranged at the bottom end of the fixing column. A lead screw is threadedly connected inside the sliding table. Fixed seats are rotatably arranged at both ends of the lead screw, and the fixed seats are fixedly connected to the housing. A driving motor for driving the lead screw is arranged on one side of one of the fixed seats. A limiting rod is slidably inserted at the bottom of the lead screw inside the sliding table, and both ends of the limiting rod are fixedly connected to the two fixed seats. When the driving motor works to drive the lead screw to rotate, the rotation of the lead screw can drive the sliding table threadedly connected thereto to move along the lead screw, and the movement of the sliding table can further adjust the position of the travel switch.

[0014] In a preferred technical solution of the present invention, the fixing column is inserted into a socket groove opened at the bottom end of the connecting block in a matching manner, and a positioning block is fixedly arranged on the outer wall of the fixing column. The positioning block is arranged in a positioning groove opened in the socket groove in a matching manner. The top end of the fixing column is provided in an arc convex shape, and a limiting groove is opened on one side of the fixing column. A spherical limiting block is arranged in the limiting groove in a matching manner. A push rod is fixedly arranged on the back side of the limiting block. One end of the push rod passes through the connecting block and is located outside the connecting block, and a pushing spring is arranged on the outer part of the push rod in a matching manner. Both ends of the pushing spring are fixedly connected to the limiting block and the connecting block respectively. By the cooperation of the positioning block and the positioning groove, the fixing column is inserted into the socket groove. When the top end of the fixing column contacts the limiting block, the limiting block will be pushed to move, and at this time, the pushing spring is stressed and in a compressed state. When the limiting block contacts the limiting groove, under the elastic action of the pushing spring, the limiting block will be pushed to be inserted and limited with the limiting groove in a matching manner, so that the connecting block and the fixing column can be inserted and fixed. When it is necessary to disassemble the travel switch, only need to pull the push rod to move the limiting block out of the limiting groove, and the separation of the connecting block and the fixing column can be realized.

[0015] In a preferred technical solution of the present invention, the triggering assembly includes a fixing rod. One end of the fixing rod is fixedly connected to the sliding seat, and a block body is fixedly arranged at the other end of the fixing rod. An active block is slidably arranged inside the block body on the side close to the travel switch. An elastic pad is fixedly arranged on the outer side of the active block. Spring blocks are fixedly arranged at the four corners on the inner side of the active block, and the other ends of the spring blocks are fixedly connected to the block body. By providing the spring blocks, when the elastic pad contacts the travel switch, the active block will be forced to move inward and compress the spring blocks. Through the elastic action of the spring blocks, the travel switch can be protected. By providing the elastic pad, the abrasion generated during the collision with the travel switch can be reduced.

[0016] The beneficial effects of the present invention are:

[0017] A highly intelligent portable ventilator provided by the present invention can adjust the position of the travel switch when the drive motor works. When the servo motor drives the slide to move, the block can be driven to move simultaneously. When the elastic pad on the block contacts the travel switch, the servo motor rotates in the reverse direction to drive the slide to move in the opposite direction. By adjusting the position of the travel switch, the moving distance of the slide can be adjusted, and then the moving distance of the push block can be adjusted to achieve different degrees of extrusion of the airbag. When the servo motor cannot work properly, the crank can be rotated to drive the half gear to rotate. The rotation of the half gear can drive the slide bar to move. When the slide bar contacts the slide, the push block can be driven to move. Therefore, even when the servo motor cannot work properly, oxygen supply and breathing for the patient can still be achieved.

[0018] For this highly intelligent portable ventilator, the connecting column and the connecting groove are matched to engage the limit card slot in the semi-circular groove. When the shell cover is closed, the position of the airbag can be limited and fixed under the interaction of the two semi-circular grooves. There is no need to install and fix the airbag, and it is also convenient to disassemble the airbag. Rotate the crank to drive the half gear to rotate. When the half gear meshes with one of the second racks, the movable frame will be pushed to move. When the movable frame moves to the maximum distance, continue to rotate the half gear, and the half gear will mesh with the other second rack. At this time, the second rack will drive the movable frame to move in the opposite direction. Therefore, when the crank is continuously rotated, the movable frame can be driven to move reciprocally.

[0019] For this highly intelligent portable ventilator, when the travel switch needs to be disassembled, just pull the push rod to move the limit block out of the limit slot, and the connection block can be separated from the fixed column. When the elastic pad contacts the travel switch, the movable block will move inward under force and compress the spring block. Through the elastic action of the spring block, the travel switch can be protected. With the provided elastic pad, the wear generated during the collision with the travel switch can be reduced.

A servo motor 807 for driving the driving gear 806 is arranged on one side of the driving gear 806. When the servo motor 807 works, it drives the first rack 805 to move. The movement of the first rack 805 can drive the pushing block 7 to move. The airbag 6 can be extruded through the pushing block 7. Through the sliding of the limiting slider 803 and the limiting sliding groove 804 in a matching manner, the stability of the position of the pushing block 7 during movement can be improved; the hand-cranking component 9 includes a movable frame 901. Slide bars 902 are fixedly arranged on both sides of the movable frame 901. One of the slide bars 902 is located on one side of the sliding seat 802.

When the servo motor 807 works to drive the sliding seat 802 to move, it can drive the block 1202 to move at the same time. When the elastic pad 1204 on the block 1202 contacts the travel switch 10, at this time, the servo motor 807 rotates in the reverse direction to drive the sliding seat 802 to move in the opposite direction. By adjusting the position of the travel switch 10, the moving distance of the sliding seat 802 can be adjusted, and then the moving distance of the push block 7 can be adjusted, so as to realize different degrees of extrusion of the airbag 6. When the servo motor 807 cannot work properly, the crank 908 can be rotated to drive the half gear 909 to rotate. The rotation of the half gear 909 can drive the sliding rod 902 to move. When the sliding rod 902 contacts the sliding seat 802, the push block 7 can move.
