Description

Severe medical science branch of academic or vocational study is supported with breathing with unobstructed ware of gas channel

Technical Field

The invention belongs to the technical field of medical equipment, and particularly relates to an airway clearing device for respiratory support in severe medical science.

Background

The airway is the respiratory passage of a human being, and is the accessory organs of the lungs, including the trachea, the throat and the nasal passages. In the department of critical care medicine, the most common medical means is to adopt an airway patency device to perform respiratory management and respiratory management support on patients with acute respiratory insufficiency or other various acute and critical patients. Because the patient of severe medical science branch of academic or vocational study often is accompanied respiratory tract phlegm or the obstructed condition of clot, not only influences the normal work of the unobstructed ware of air flue, still can bring very big inconvenience for doctor's treatment, so breathe the management and breathe the management support to the patient before, still need guarantee that the air flue is unobstructed, need clear up patient's air flue promptly.

The prior airway patency device has the following problems:

(1) because the foreign matter in the mode suction air flue through bleeding, during the absorption, because the foreign matter is comparatively thick, perhaps discontinuous, can be interrupted in the intubate and the negative pressure is shrivelled, the unstable condition of intubate head suction, not only can not be quick, abundant thorough suction foreign matter, still can be in the twinkling of an eye that the foreign matter got into the intubate, the suction is too big, arouses the uncomfortable problem of patient.

(2) The device does not have an airway expansion function, and cannot effectively carry out respiratory management support on a patient with tracheal stenosis.

(3) The existing airway patency device is too complex in structure and inconvenient to use.

Disclosure of Invention

The invention aims to provide an airway smoothing device for supporting respiration for severe medical science, which solves the problems that the existing airway smoothing device cannot rapidly, fully and thoroughly suck out foreign matters, and the suction force is too large at the moment when the foreign matters enter an intubation tube, so that the patient is uncomfortable.

In order to achieve the purpose, the technical scheme of the invention is as follows:

As shown in fig. 2, the right end of the outer layer pipe 101 is connected to the outer connection pipe 2 through an outer connection port, and the right end of the middle layer pipe 102 is connected to the middle connection pipe 3 through a middle connection port 105.

The left end of inner core 103 is connected with end 8 as an organic whole, and the cross section of end 8 is greater than the cross section of inner core 103, and inner core 103 can be closed well gas outlet through end 8.

Referring to fig. 1, the respiratory management support chamber 5 is provided with a plurality of sets of first pulling members 6 capable of controlling the distance between the outer tube 101 and the middle tube 102 to be changed along the central line direction of the outer tube 101 and the middle tube 102, and specifically, the first pulling members 6 include hooks 602 integrally connected to the inner side wall of the middle tube 102 and hanging rings 601 integrally connected to the inner core 103.

As shown in fig. 2, the longitudinal section of the outer connecting pipe 2 is shaped like a T, the outer connecting pipe 2 includes an air suction part 201 and a foreign matter discharging part 202 which are oppositely arranged, and the air suction part 201 is connected with an external air suction pump. The longitudinal section of the middle connecting pipe 3 is L-shaped. Specifically, a filter net for preventing foreign matters from entering the suction pump is fixedly connected to the suction portion 201 of the outer connection pipe 2 through a bolt.

The embodiment further comprises a second pulling part capable of controlling the movement of the inner core 103, specifically, the second pulling part comprises a supporting rod 701, a supporting block 703 and a handle 702, the supporting block 703 is integrally connected in the middle connecting pipe 3, vent holes are formed in the circumferential direction of the supporting block 703, the supporting rod 701 penetrates through the supporting block 703 and is slidably connected with the supporting block 703, the left end of the supporting rod 701 is in threaded connection with the inner core 103, and the right end of the supporting rod 701 penetrates through the middle connecting pipe 3 and is fixedly connected with the handle 702 through a bolt. The medical staff can control the inner core 103 to move by the support rod 701 by pushing the handle 702.

When the airway patency device for supporting respiration works, an inhalation cavity 4 for removing foreign matters and a respiration management support cavity 5 for supporting respiration management are separated.

Firstly, the outer connecting port at the right end of the outer pipe 101 is connected with the outer connecting pipe 2, the middle connecting port 105 at the right end of the middle pipe 102 is connected with the middle connecting pipe 3, the inner core 103 is inserted from the middle air outlet at the left end of the middle pipe 102, and the inner core 103 is rotated to lead the inner core 103 to be in threaded connection with the support rod 701.
