Description

It can continue the trachea cannula of inflation

Technical field

The utility model relates to manufacture technology field of medical appliance, especially a kind of trachea cannula that can continue inflation.

Background technique

Trachea cannula is the intubation by a special endotracheal tube through patient's glottis merging tracheae, is the gas of patient with severe symptoms Road is unobstructed, ventilation oxygen-supplying, respiratory tract attract and prevents from accidentally inhaling etc. provides optimum condition.Existing trachea cannula generally comprises bending Tube body, one end of tube body is equipped with connector, and another end opening protheca has an air bag for being inserted into patient airway, with support Patient airway's inner wall has a gas tube to pass through and protrudes into air bag, to guarantee that air bag enters in patient airway always for air bag inflation Keep specific pressure value (25~30cmH₂O), hypertonia will affect air flue mucous membrane blood supply, and result of study is shown, work as air bag Pressure is more than 30cmH₂When O, mucous membrane capillary blood flow starts to reduce；When air bag is pressed more than 50cmH₂When O, blood flow is blocked completely. Tracheal mucosa compressing is more than certain time, will lead to the even necrosis of tracheal mucosa ischemia injury, tracheae food can occur when serious Pipe fistula；On the contrary, air bag can not be closed with gas tube junction if gasbag pressure is insufficient, the secretion of patient's upper respiratory tract holds Lung easily is fallen into, leads to mechanical ventilation gas leakage, accidentally suction, Ventilator Associated Pneumonia etc..And to maintain gasbag pressure in normal model It encloses, needs every 6 to 8 hours measurement pressure 1 time, labor intensive resource, working efficiency is greatly affected.

Summary of the invention

The problem to be solved by the utility model is to provide a kind of trachea cannulas that can continue inflation, to solve existing tracheae It is intubated and is difficult to control gasbag pressure, ineffective problem.

To solve the above-mentioned problems, the technical solution of the utility model is: the trachea cannula that instinct is persistently inflated includes one End is equipped with the tube body that air bag is cased with outside connector other end front, further includes the gas tube for being passed through air bag, and the gas tube is from institute It states by being passed through the air bag in the tube wall of tube body outside tube body, the one end of the gas tube except the tube body is connected to pressure control Air bag, the pressure control air bag are equipped with the gas-charging connection for connecting charger, the air bag and the pressure control air bag and institute State gas tube sealed connection.

In above-mentioned technical proposal, more specifically scheme may is that the pressure control air bag is set to the gas tube in described The exit of tube body tube wall.

Further: the air bag and the pressure control air bag are that silica gel material is made.

Further: the air bag is silica gel air bag, and the pressure control air bag is rubber pressure control air bag.

Further: the gas tube is silica gel gas tube.

By adopting the above-described technical solution, the utility model has the following beneficial effects: compared with prior art

The trachea cannula that instinct is persistently inflated uses the additional air bag of gas tube, i.e. pressure control air bag and gas tube and air bag For a closed space, make air bag no longer gas leakage；Before use, rousing them without enough gas in air bag and pressure control air bag It rises, in use, the balloon sites of this intubation enter patient airway, charger connects the gas-charging connection on pressure control air bag, pressure control Air bag and air bag, which are inflated, to be heaved, and after being inflated to gasbag pressure optimum value, is stopped inflation, due to air bag, pressure control air bag and is filled Tracheae is air tight, and the air pressure in air bag remains unchanged, only when patient's postural change is intratracheally pressed with microvariations, air bag pressure Power is bigger, then gas is forced into automatically in pressure control air bag, and pressure control air bag volume becomes larger a bit, and gasbag pressure is smaller, pressure control air bag Gas enter air bag, pressure control air bag volume becomes smaller a bit, when needing to increase larger pressure, need to just open charger inflation, The difficult problem of intracapsular pressure control has been well solved, without using single-way gas-discharge valve, while having solved air resource wave again Take, the problem that charger energy consumption is high；Gas tube mistake in tube body tube wall, when selecting silica gel material to do gas tube, gas tube Will not volume expansion it is too many, and overall structure is simple, and solving existing trachea cannula, structure is complicated, problem inconvenient for use；

The trachea cannula that instinct is persistently inflated can constantly stablize gasbag pressure in 25~30cmH₂O, without in addition Increase manpower control, greatly improve working efficiency, and easy to use, manufacturing cost is low, low energy consumption, can be widely applied to weight The clinical application of disease monitoring.

Detailed description of the invention

Fig. 1 is the main view of the utility model embodiment.

Specific embodiment

The utility model embodiment is described in further detail with reference to the accompanying drawing:

The trachea cannula that instinct as shown in Figure 1 is persistently inflated, it includes that one end is equipped with 1 other end front housing of connector There is the tube body 2 of air bag 6, further includes the gas tube 5 for being passed through air bag 6, gas tube 5 is outside tube body by being passed through in the tube wall of tube body 1 Air bag 6, opening 7 of the gas from gas tube 5 to air bag 6 enter air bag, and the one end of gas tube 5 except tube body 1 is connected to pressure control Air bag 3, pressure control air bag 3 is equipped with the gas-charging connection 4 for connecting charger, air bag 6 and pressure control air bag 3 and gas tube 5 is close Envelope connection.Using the additional air bag of gas tube 5, i.e. pressure control air bag 3 and gas tube and air bag is a closed space, makes air bag 6 No longer gas leakage, before use, heaving them without enough gas in air bag and pressure control air bag, in use, the gas of this intubation Capsule position enters patient airway, and charger connects the gas-charging connection 4 on pressure control air bag 3, pressure control air bag and the equal aeration drum of air bag It rises, after being inflated to 6 pressure optimum value of air bag, stops inflation, since air bag 6, pressure control air bag 3 and gas tube 5 are air tight, air bag Air pressure in 6 remains unchanged, and only when patient's postural change is intratracheally pressed with microvariations, 6 pressure of air bag is bigger, then gas Automatically it is forced into pressure control air bag 3,3 volume of pressure control air bag becomes larger a bit；6 pressure of air bag is smaller, and the gas of pressure control air bag 3 enters Air bag, 3 volume of pressure control air bag becomes smaller a bit, when needing to increase larger pressure, need to just open charger inflation, well solve The difficult problem of pressure control in air bag 6, without using single-way gas-discharge valve, while again solve air resource waste, inflation is set The standby high problem of energy consumption.

Pressure control air bag 3 is set to gas tube 5 in the exit of 1 tube wall of tube body, and gas tube 5 is silica gel gas tube, air bag 6 and control Pressuring gasbag 3 is that silica gel material is made, and gas tube mistake in tube body tube wall, when silica gel material does gas tube 5, gas tube will not Volume expansion is too many, and overall structure is simple, and solving existing trachea cannula, structure is complicated, problem inconvenient for use.Instinct is held The trachea cannula of continuous inflation can constantly stablize gasbag pressure in 25~30cmH₂O, without in addition increasing manpower control, pole The earth improves work efficiency, and easy to use, and manufacturing cost is low, low energy consumption, and the clinic that can be widely applied to Intensive Care Therapy is answered With.

In other embodiments, air bag can also be selected as silica gel air bag, and pressure control air bag can select rubber pressure control air bag.
