Abstract

A kind of trachea cannula, including main tracheae, the main tracheae top of installation gas-tpe fitting, be arranged on air bag, the gas tube being connected with air bag, the charge valve installed in gas tube top of main tracheae bottom, in main tracheae both sides, suction tube on left and right capsule is set, it is located at two groups of side openings that left and right arrangement is set above air bag at 5mm-10mm in main tracheae, every group of side opening is respectively 2-4, infratubal port is attracted to correspond to two groups of side openings respectively on the left and right capsule, one of which side opening is air inlet, and another group of side opening is leakage fluid dram.The secretion such as its sputum that can produce patients with respiratory tract, extravasated blood suction out, and balance pressure in respiratory tract, avoid the occurrence of respiratory distress, the symptom such as oxygen saturation declines rapidly, reduce patient and be critically ill risk.

Description

Trachea cannula

Technical field

The present invention relates to medical instrument, more particularly to trachea cannula.

Background technology

Trachea cannula be CPR and with respiratory dysfunction Severe acute disease patient rescue during important doctor Apparatus is treated, trachea cannula can be that patient is sufficiently fed oxygen, keeps respiratory passage unblocked at any time, meanwhile, trachea cannula is also to rob Rescue Cavity in Critical Patients and establish that artificial airway is most effective, efficiently method.Due to carrying out in endotracheal intubation, trunnion can produce phlegm The secretion such as liquid, extravasated blood, existing trachea cannula cannot remove the secretion of trunnion generation in time, when trunnion excess secretion, When cannot be flowed out at mouth, nose or cutting opening again, pressure in patients with respiratory tract can be caused to increase, respiratory distress, oxygen saturation occur The symptoms such as the rapid decline of degree, the risk that patient is critically ill are high.

The content of the invention

In order to solve the above-mentioned technical problem the present invention is, there is provided a kind of trachea cannula, it can produce patients with respiratory tract Sputum, the secretion such as extravasated blood suction out, balance pressure in respiratory tract, avoid the occurrence of respiratory distress, oxygen saturation declines rapidly etc. Symptom, reduces patient and is critically ill risk.

The present invention technical solution be：

A kind of trachea cannula, including main tracheae, the main tracheae top of installation gas-tpe fitting, be arranged on the gas of main tracheae bottom Capsule, the gas tube being connected with air bag, the charge valve installed in gas tube top, it is characterized in that：Set in main tracheae both sides Suction tube on left and right capsule is put, two groups of side openings that left and right arrangement is set above air bag at 5mm-10mm are located in main tracheae, often Group side opening is respectively 2-4, attracts infratubal port to correspond to two groups of side openings respectively on the left and right capsule, one of which side is opened Mouth is air inlet, and another group of side opening is leakage fluid dram.

Further preferably, the left and right side opening is respectively 3 or 4, suction tube lower end on the corresponding left and right capsule The quantity of mouth is 2 or 3 and is located at respectively between two adjacent side openings.

Further preferably, left and right side open amount differs, the side that the side opening more than quantity is air inlet, quantity is few It is open as leakage fluid dram.

Further preferably, the left and right side opening protrudes from main tracheae outer wall and outer end face is spherical, avoids scratch patient Trunnion.

Further preferably, suction tube is pasted on main inner surface of trachea on the capsule.

The beneficial effects of the invention are as follows：

Two groups of side openings of left and right arrangement, left and right capsule are set due to being located in main tracheae above air bag at 5mm-10mm Upper attraction infratubal port corresponds to two groups of side openings respectively, and one of which side opening is air inlet, and another group of side opening is leakage fluid dram. When suction sputum operates, main tracheae tail end is inserted into patient's trunnion first, by the syringe that is connected on charge valve to airbag aeration, Make air bag is swollen to be attached to patient's trunnion inner wall, avoid sputum, extravasated blood from entering patients with respiratory tract；Again by suction tube connection note on two capsules Emitter, the syringe connected with air inlet inject air pressure into patient's trunnion, the sputum of air inlet side, extravasated blood are blowed to leakage fluid dram Side, the syringe connected with leakage fluid dram outwards suction out air pressure, will be pooled to the sputum of leakage fluid dram side, extravasated blood all suctions out patient's larynx Pipe, sputum, extravasated blood are suctioned out without dead angle, balance pressure in respiratory tract, avoid the occurrence of the decline etc. rapidly of respiratory distress, oxygen saturation Symptom, reduces patient and is critically ill risk.

Fig. 2 is A-A sectional views in Fig. 1；

In figure：The main tracheaes of 1-, 2- gas-tpe fittings, 3- air bags, 4- gas tubes, 5- charge valves, suction tube on 6- capsules, 7- discharge opeings Mouthful, 8- air inlets.

Embodiment

As shown in Figure 1 and Figure 2, a kind of trachea cannula, including main tracheae 1, the gas-tpe fitting 2, viscous on main 1 top of tracheae of installation Air bag 3, the gas tube 4 being connected with air bag 3, the charge valve 5 installed in 4 top of gas tube of main 1 bottom of tracheae are attached to, in main gas Suction tube 6 on left and right capsule is pasted in 1 inner wall both sides of pipe, is located in main tracheae 1 above air bag 3 and the two of left and right arrangement is equipped with 10mm Group side opening, the left and right side opening protrudes from main 1 outer wall of tracheae and outer end face is spherical, and left side opening is leakage fluid dram 7, number Measure as 3, right openings are air inlet 8, and quantity is 4, and the quantity of 6 lower port of suction tube is 2 on left bladder, on left bladder 6 lower port of suction tube is between adjacent two leakage fluid drams 7, and 6 lower port quantity of suction tube is 3 on right side bladder, on right side bladder 6 lower port of suction tube is between adjacent two air inlets 8.

When suction sputum operates, main 1 tail end of tracheae is inserted into patient's trunnion first, air bag 3 is located at trunnion place on the lower side, then will Charge valve 5 connects syringe, injects air pressure to air bag 3 by syringe, makes air bag 3 is swollen to be attached to patient's trunnion inner wall, avoid phlegm Liquid, extravasated blood enter patients with respiratory tract；Suction tube 6 on two root pockets is connected into syringe again, the syringe connected with air inlet 8 is to trouble Injection air pressure, 7 side of leakage fluid dram is blowed to by the sputum of 8 side of air inlet, extravasated blood in person's trunnion, with the syringe that leakage fluid dram 7 is connected to Outer sucking-off air pressure, will be pooled to the sputum of 7 side of leakage fluid dram, extravasated blood suctions out patient's trunnion.

It these are only the specific embodiment of the present invention, be not intended to limit the invention, for those skilled in the art For member, the invention may be variously modified and varied.Any modification within the spirit and principles of the invention, being made, Equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
