Description

Disposable sterile silica gel trachea cannula

Technical Field

The utility model relates to the technical field of medical equipment, especially a disposable aseptic silica gel trachea cannula.

Background

The trachea cannula is an important measure for establishing an artificial respiratory tract, ensuring the smoothness of the respiratory tract and meeting the oxygen requirement of the organism and the excretion of CO2, is an indispensable basic technology in modern anesthesiology and modern emergency medicine, is a key technology for ventilation support and respiratory therapy, and plays a key role in rescue and treatment of critically ill and difficult patients and cardiopulmonary resuscitation.

At present, the traditional tracheal cannula has a complex structure and high cost, is usually used repeatedly, and cannot ensure the safe use among patients; moreover, the traditional trachea cannula is inconvenient to use and easy to shift and separate; in addition, most of the traditional trachea cannula is made of PVC materials and is not suitable for long-term intubation.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model provides a disposable sterile silica gel trachea cannula.

The utility model adopts the technical proposal that:

a disposable sterile silica gel trachea cannula comprises a silica gel catheter, a spring, a cuff, an inflation tube and a connector; the spring is arranged in the silica gel guide pipe, and the length of the spring is matched with that of the silica gel guide pipe; one end of the silica gel catheter is a patient end provided with a patient using port, and the other end of the silica gel catheter is a machine end provided with a machine connecting port; the cuff is sleeved on the part, close to the end of the patient, of the silica gel catheter; one end of the inflation tube extends into the silica gel guide tube from the part, close to the machine end, on the silica gel guide tube and is connected with the cuff, and the other end of the inflation tube is connected with a one-way valve through a clamping ring; the machine end of silica gel pipe is connected with the joint, the other end that connects relative with the silica gel pipe is connected with the seal wire fixer, the center of seal wire fixer is equipped with the design seal wire.

Preferably, an indicating balloon is connected between the clamping ring and the inflation tube.

Preferably, the linker is a 15mm standard linker.

Preferably, the port of the patient end of the silicone catheter has a bevel angle.

The utility model has the advantages that:

1. the structure is simple, the cost is low, the disposable use is realized, and the safety and cleanness among patients are ensured;

2. the silica gel material is adopted, compared with the traditional PVC material, the silica gel has excellent physiological inertia, no toxicity, no odor, no corrosion, anticoagulation, good compatibility with organisms and capability of enduring harsh disinfection conditions, and the silica gel trachea cannula made of the silica gel material is soft, has small damage to the oropharynx and the airway mucosa of a human body, generates mucosal congestion after operation and has low hoarseness probability;

3. when the silica gel trachea cannula is used, a syringe is used for injecting gas with a certain volume into the cuff through the one-way valve and the inflation tube, and after the cuff is inflated, the outer wall of the trachea cannula and the trachea wall form sealing besides the fixing function; after the injector is pulled out, the valve of the one-way valve is closed to prevent the cuff gas from leaking out, and the doctor can monitor whether the balloon is in a normal working state or not by indicating the deflated or inflated state of the balloon.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

reference numerals: 10. the device comprises a silica gel catheter, 11, a patient end, 12, a machine end, 20, a spring, 30, a cuff, 40, an inflation tube, 41, an indication balloon, 42, a clamping ring, 43, a one-way valve, 50, a connector, 51, a guide wire fixer, 52 and a shaping guide wire.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

As shown in fig. 1, a disposable sterile silica gel trachea cannula comprises a silica gel catheter 10, a spring 20, a cuff 30, an inflation tube 40 and a connector 50; the spring 20 is arranged in the silica gel guide tube 10, and the length of the spring 20 is matched with that of the silica gel guide tube 10; one end of the silica gel catheter 10 is a patient end 11 provided with a patient using port, and the other end is a machine end 12 provided with a machine connecting port; the cuff 30 is sleeved on the part, close to the patient end 11, of the silica gel catheter 10; one end of the inflation tube 40 extends into the silica gel guide tube 10 from the part, close to the machine end 12, on the silica gel guide tube 10 and is connected with the cuff 30, and the other end of the inflation tube 40 is connected with a one-way valve 43 through a clamping ring 42; the machine end 12 of silica gel pipe 10 is connected with connects 50, the other end that connects 50 and silica gel pipe 10 relative is connected with seal wire fixer 51, the center of seal wire fixer 51 is equipped with design seal wire 52.

When in use, the cuff 30 is inflated by injecting a certain volume of gas into the cuff 30 through the one-way valve 43 and the inflation tube 40, and the cuff 30 plays a role in fixing and also forms a seal between the outer wall of the tracheal cannula and the tracheal wall. After the syringe is pulled off, the valve of the one-way valve 43 is closed to prevent the gas in the cuff 30 from leaking out.

The shaping guide wire 52 can be bent into an arc shape to shape and bend the silica gel catheter 10, so that the patient end 11 of the silica gel catheter 10 can conveniently reach the throat, and the spring 20 can prevent the silica gel catheter 10 from being bent excessively, so as to avoid the silica gel catheter 10 from damaging the throat.

In one embodiment, an indicator balloon 41 is connected between the snap ring 42 and the inflation tube 40.

The physician can monitor whether the balloon is functioning properly by indicating the deflated or inflated state of the balloon 41. Before tube drawing, the balloon is deflated and then the tube is drawn.

In one embodiment, the fitting 50 is a 15mm standard fitting 50.

In one embodiment, the patient end 11 of the silicone catheter 10 is ported with a beveled angle.

The bevel angle can facilitate the introduction of the silica gel catheter 10 into the trachea, and can increase the area of the port, so that foreign matters such as sputum and the like can be sucked out quickly.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
