Abstract
The utility model discloses a closed tracheal catheter inflation cuff. The upper end of an air storage display bag is provided with an upper interface, and the lower end is provided with a lower interface; a cylindrical inflation tube is arranged in the upper interface; the orifice of the inflation tube is covered with a rubber gland; a pressure hoop is sealed on the outer side of the gland; an inflation cuff inflation tube is arranged in the lower interface; and the bottom end of the inflation cuff inflation tube is provided with an inner inflation cuff. In the assembly and production process, the inner inflation cuff is sheathed and fixed on the outer wall of the tracheal catheter, the inner inflation cuff inflation tube closely abuts against the inner wall of the tracheal catheter, and the upper end is led out of the catheter through the outlet orifice of the inflation tube. When in use, air can be injected by penetrating an injector into the gland through an inflation hole in the upper end surface of the pressure hoop.
Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of inflatable cuff that is used for endotracheal tube.
Background technology
Endotracheal tube is the anesthesia and the common tool of rescuing the critical patient, and inflatable cuff is that cuff for endotracheal catheter is inflated or shown sheathed catheter capsule air pressure size, and the anti-key operation monitoring capsule of letting out leak-stopping.Existing inflatable cuff is in the inflation inlet of cover capsule, to be provided with spring pressure flap valve on the market; Utilize the turnover of the flap valve effect control gas of spring bearer plate during use; But because the volume of sleeve bag gas-filling mouth is limited, the volume of equipped elastic force flap valve is less, and production and processing technology is complicated; Required precision is high, gas leakage easily in the use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of closed endotracheal tube inflatable cuff is provided, and with easy producing process, prevents gas leakage.
The scheme of this utility model shows that by gas storage bag, rubber gland reach interior inflatable cuff and form; Its construction features is that described gas storage shows that bag is transparent pouch, shows that in gas storage the upper end of bag is provided with interface, and the lower end is provided with lower interface; Cylindrical gas tube is housed in the last interface; Be stamped rubber gland on the mouth of pipe of gas tube, the outer side seal of gland has the hoop of pressure, presses the upper surface of hoop to leave air-filled pore; Inflatable cuff gas tube in being equipped with in the lower interface, the bottom of interior inflatable cuff gas tube is provided with interior inflatable cuff.During the assembling processing; Interior inflatable cuff suit is fixed on the outer wall of endotracheal tube; Be close to interior inflatable cuff gas tube on the inwall of endotracheal tube, the upper end shows that bag and cylindrical gas tube are arranged on the lower end of endotracheal tube connector to gas storage by outside the gas tube outlet spout extraction catheter.During use, can inject air with syringe by pressing the air-filled pore that binds round the upper surface to thrust in the gland, described gland can be selected the material seal of flexible plastic or other good toughness for use.
This utility model is simple in structure, and is reasonable in design, easy to install, the operation good fixing effect.
Do further explain below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is this utility model structural representation;
Fig. 2 uses sketch map for assembling.
The specific embodiment
Gas storage shown in Fig. 1-2 shows that the upper end of bag 4 is provided with interface 5; The lower end is provided with lower interface 3, and cylindrical gas tube 6 is housed in the last interface, is stamped rubber gland 8 on the mouth of pipe of gas tube; The outer side seal of rubber gland has the hoop of pressure 7; Press the upper surface of hoop to leave air-filled pore, inflatable cuff gas tube 2 in being equipped with in the lower interface, the bottom of interior inflatable cuff gas tube is provided with interior inflatable cuff 1.
Interior inflatable cuff 1 suit shown in Fig. 2 is fixed on the outer wall of endotracheal tube 9; Interior inflatable cuff gas tube 2 is close on the inwall of endotracheal tube; The upper end is by outside gas tube outlet spout 10 extraction catheters, and gas storage shows that bag 4 and cylindrical gas tube 7 are arranged on the lower end of endotracheal tube connector 11.
