[0001] The present application relates to the technical field of ventilators, and in particular to a simple ventilator. Background Art

[0002] In the prior art, a ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. Existing ventilators generally require an external power supply when in use. However, for some emergency treatment operations, the usage scenarios are often not equipped with power supply, resulting in the ventilator being unable to provide timely treatment to the patient, delaying the optimal treatment time. Utility Model Content

[0003] The problem to be solved by the present application is that the existing ventilators need to be connected to electricity, which makes them unusable in some emergency situations due to failure to connect to electricity, resulting in the ventilator being unable to provide timely treatment to the patient, delaying the optimal treatment time.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0015] The present application relates to a simple respirator, such as Figure 1-7 As shown, the respirator includes a shell 4 for supporting and covering, a ventilation assembly 5 for breathing ventilation is arranged inside the shell 4, and ducts 1 for gas transmission are arranged at both ends of the ventilation assembly 5. In order to facilitate the maintenance and repair of the ventilation assembly 5, a shell cover 2 detachably connected thereto is arranged on the top of the shell 4. In order to prevent the respirator from being unable to be used in a scenario where it cannot be powered on, a drive assembly 3 that can drive the ventilation assembly 5 electrically or manually is added inside the shell 4. In order to prevent electric and manual interference, a transmission assembly 6 that can transmit simultaneously without mutual interference is added between the drive assembly 3 and the ventilation assembly 5. With the help of the design of the transmission assembly 6, the free switching operation of electric or manual driving mode is realized.

[0016] The ventilation assembly 5 includes an airbag 17, a cover plate 18, a connecting rod 19, and a roller 20. There are two airbags 17, which are symmetrically arranged at the two ends of the shell 4. One end of the shell 4 is provided with a cover plate 18 for supporting force, and the end of the cover plate 18 is provided with a roller 20 for rolling contact and force movement. In order to realize the alternating telescopic movement of the two cylinders, connecting rods 19 for linkage are symmetrically arranged on the upper part of the cover plate 18, so that the airbag 17 can achieve alternating telescopic air replacement action with the help of the connecting rod 19.

[0017] The transmission assembly 6 includes a gear set 11, a cam 10, and a worm 16. The cam 10 is arranged inside the housing 4 and abuts against the roller 20, so that the two airbags 17 can be pressed to perform alternating telescopic operations by means of the rotation of the cam 10. A gear set 11 and a worm 16 for realizing power transmission operations are arranged on one side of the cam 10. The gear set 11 is connected to the cam 10, and the worm 16 is meshed with the gear set 11, so that the cam 10 can be driven to rotate by the self-rotation of the gear set 11, and the worm 16 can be rotated, and then the cam 10 can be driven to rotate by the gear set 11, thereby realizing two power input methods without mutual interference.

[0018] The gear set 11 includes an internal gear 15, an external gear 12, a ring gear 13, and a support ring 14. The internal gear 15 is arranged at the position of the gear set 11. A shaft 8 is arranged at one end of the internal gear 15. There are multiple external gears 12, which are evenly arranged in the circumferential direction of the internal gear 15 and meshed with it. A ring gear 13 meshed with it is also arranged on the outer edge of the external gear 12, and the outer side of the ring gear 13 is meshed with the worm 16. In order to realize the linkage movement between the multiple external gears 12, a support ring 14 connected to the multiple external gears 12 is added on one side of the ring gear 13, so that the ring gear 13 can drive the internal gear 15 to rotate with the help of the transmission of the external gear 12, and the internal gear 15 can also rotate independently.

[0019] The driving assembly 3 includes a motor 9, a lever 7, and a handle 21. The motor 9 is arranged inside the housing 4 and connected to one end of the worm 16, so that the worm 16 is driven to operate by means of the motor 9, and the lever 7 is arranged at one end of the shaft 8, so that the lever 7 drives the internal gear 15 to operate by means of the shaft 8. In order to facilitate manual driving of the lever 7, a handle 21 that is easy to hold is arranged at the end of the lever 7, and a groove that can fold and store the handle 21 is also arranged on the upper part of the lever 7, so that the ventilator can be electrically driven with the help of the motor 9, and the ventilator can also be manually driven with the help of the handle 21.

[0020] When in use, first connect the cylinder to the external oxygen cylinder, and then in a power supply scenario, connect the external power supply to make the motor 9 drive the worm 16 to rotate, and the worm 16 will drive the ring gear 13 meshing with it, and then the ring gear 13 drives the outer gear 12 to rotate in place, and as the outer gear 12 rotates, it will drive the inner gear 15 meshing with it to rotate synchronously, and the inner gear 15 will drive the cam 10 to rotate. At this moment, the inner cam 10 will rotate synchronously, and the roller 20 abutting against the surface of the cam 10 will press the cylinder to perform telescopic ventilation movement as the cam 10 rotates. Since two groups of air bags 17 are arranged inside the shell 4, breathing and air supply operations can be performed on two patients at the same time. If only a single patient is supplied with air, only the external An oxygen cylinder is enough; when the respirator does not have an external power supply, an emergency manual drive operation can be performed at this moment. At this time, by removing the handle 21 from the groove of the lever 7, and then rotating the handle 21 clockwise, the handle 21 will directly drive the internal gear 15 to rotate with the help of the shaft 8 connected to the lever 7, and then the internal gear 15 will drive the cam 10 to rotate synchronously, so that the cylinder extension and ventilation operation can still be realized. Because the rotation of the internal gear 15 will drive the external gear 12 to rotate, and the ring gear 13 outside the external gear 12 is meshed with the worm 16, the external gear 12 cannot rotate, so as to avoid burning the motor 9 during manual rotation, thereby realizing that the respirator can seamlessly switch between electric drive and manual drive mode, ensuring that the patient can receive timely exhalation and ventilation rescue.

In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application.
