Abstract
The utility model discloses a nursing type pressure regulating needle head, comprising a head part (4) which is connected with an injector, and a needle tube (1) which is connected to the head part (4), an air duct (2) is arranged along the axial direction of the needle tube (1), the air duct (2) is provided with an opening which is near to the top part of the needle tube (1) and is provided with an air outlet (3) which is near the bottom part of the needle tube (1). The nursing type pressure regulating needle head can be used conveniently to inject medical liquid into a sealed bottle or draw the medical liquid from the sealed bottle, the structure is simple and the production is convenient.
Description
Technical field
This utility model relates to a kind of syringe needle, particularly relates to a kind of nursing technical ability adjust blood pressure syringe needle.
Background technology
Clinical care is made up a prescription and common syringe needle is generally used in the drawing liquid operation, the structure of common syringe needle comprises the head that is connected with syringe and is connected needle tubing on the head, need be in the sealing fluid bottle injection or therefrom during pumping liquid, the needle tubing of common syringe needle is inserted into carries out injection or suction in the air-tight bottle, usually because pressure of the inside of a bottle becomes and is higher or lower than atmospheric pressure and causes and make up a prescription or the difficulty of drawing liquid body.
The utility model content
Technical problem to be solved in the utility model provide a kind of can be easily in the sealing fluid bottle injection or the nursing technical ability adjust blood pressure syringe needle of pumping liquid therefrom.
In order to solve the problems of the technologies described above, the nursing technical ability adjust blood pressure syringe needle that this utility model provides, comprise the head that is connected with syringe and be connected needle tubing on the head, it is axially arranged with airway in described needle tubing upper edge, it is opening that described airway closes on described needle tubing top, closes on described needle tubing root and is provided with venthole.
Adopt the nursing technical ability adjust blood pressure syringe needle of technique scheme, because it is axially arranged with airway in the needle tubing upper edge, it is opening that airway closes on the needle tubing top, close on the needle tubing root and be provided with venthole, need be in the sealing fluid bottle injection or pumping liquid therefrom, the needle tubing of syringe needle is inserted into when carrying out injection or suction in the air-tight bottle, airway makes interior the connection with atmosphere of bottle regulate pressure, make pressure of the inside of a bottle can not be higher or lower than atmospheric pressure, make it keep balance with atmosphere all the time, thereby overcome in the bottle problem with making up a prescription of causing of atmospheric pressure imbalance or drawing liquid body difficulty.This utility model is only in that it is axially arranged with airway in the needle tubing upper edge, and is simple in structure, easily manufactured.
In sum, this utility model be a kind of can be easily in the sealing fluid bottle injection or therefrom pumping liquid and simple in structure, easily manufactured nursing technical ability adjust blood pressure syringe needle.
Description of drawings
Accompanying drawing is this utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to accompanying drawing, the head 4 that is connected with syringe is provided with needle tubing 1, and it is axially arranged with airway 2 in needle tubing 1 upper edge, and it is opening that airway 2 closes on needle tubing 1 top, closes on needle tubing 2 roots and is provided with venthole 3.
Referring to accompanying drawing, the needle point of needle tubing 1 is passed air-tight bottle rubber seal, airway 2 is communicated with the outer atmosphere of bottle, during drawing liquid air-tight bottle is inverted, make pin be dipped in the liquid for a short time; Air-tight bottle is upright during injection, and the pushing syringe piston gets final product.Adopt the nursing technical ability adjust blood pressure syringe needle of technique scheme, because it is axially arranged with airway 2 in needle tubing 1 upper edge, it is opening that airway 2 closes on needle tubing 1 top, close on needle tubing 1 root and be provided with venthole 3, need be in the sealing fluid bottle injection or pumping liquid therefrom, the needle tubing 1 of syringe needle is inserted into when carrying out injection or suction in the air-tight bottle, airway 2 makes interior the connection with atmosphere of bottle regulate pressure, make pressure of the inside of a bottle can not be higher or lower than atmospheric pressure, make it keep balance with atmosphere all the time, thereby overcome in the bottle problem with making up a prescription of causing of atmospheric pressure imbalance or drawing liquid body difficulty.This utility model is only in that it is axially arranged with airway 2 in needle tubing 1 upper edge, and is simple in structure, easily manufactured.
Claims (1)
