| titleOfInvention | Anti-backflow positive-pressure transfusion needleless connector |
| abstract | The utility model discloses an anti-backflow positive pressure transfusion needleless connector, which relates to the field of medical appliances, and comprises a connector upper cover and a connector lower cover, wherein the connector upper cover and the connector lower cover are connected into a closed shell, a valve core is arranged in the shell, and the bottom of the valve core is sealed with the connector lower cover; the inner cavity of the joint upper cover is provided with 6 water flow grooves, the upper portion of the valve core is relatively provided with a first arc-shaped notch and a second arc-shaped notch, the radian of the first arc-shaped notch is larger than that of the second arc-shaped notch, the lower portion of the valve core is provided with a hollow cavity, the joint lower cover is provided with a liquid channel, the top of each water flow groove is communicated with the first arc-shaped notch or the second arc-shaped notch, and the hollow cavity is communicated with the outside through a lower cover vent hole. The utility model discloses a needleless connector not only can prevent that the particle from dropping into the liquid medicine when using, and is relatively safe, can avoid producing the negative pressure moreover, prevents to flow backwards. |
