Description
Technical field
The utility model relates to venous blood-taking apparatus under medical appliance field more particularly to a kind of varied angle hysteroscope.
Background technique
Clinically, it in order to more be apparent from the state of an illness, needs to carry out venous blood collection to intracorporeal organ.Current blood sampling
Mode is to clamp the needle tubing of blood taking needle using tweezers to be operated, due to intracorporeal organ complex distribution, vein blood vessel caliber in addition
It is smaller, it is easy to vein blood vessel be penetrated, blood loss is caused, therefore blood collection procedure difficulty is larger, expend a large amount of physical strength and energy.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides venous blood-taking apparatus under a kind of varied angle hysteroscope, convenient pair
Intracorporeal organ carries out venous blood collection, greatly reduces blood sampling difficulty.
The utility model is achieved by the following technical solution, and provides venous blood-taking apparatus under a kind of varied angle hysteroscope,
Including casing and blood taking needle, the blood taking needle includes the needle tubing being slidably connected in described sleeve pipe, and is sequentially connected from the needle tubing
Interconnecting piece, preceding hose, hard tube and rear hose, the outer diameter of the interconnecting piece is greater than the needle tubing outer diameter；Described sleeve pipe includes sky
Heart pipe and the syringe needle guide portion for being fixed in the hollow pipe front end, the syringe needle guide portion, which is equipped with towards hollow pipe axis, to be extended
Guide surface, the through slot being adapted to the needle tubing is offered in the guide surface, the through slot two sides are equipped with guiding wall, and two sides are drawn
The spacing of guide wall is adapted to interconnecting piece outer diameter.
This programme when in use, first will needle tubing be retracted hollow pipe in, wait hollow pipes in place after, push hard tube, pass through needle tubing
It crosses through slot to skid off along guiding wall, when syringe needle guide portion slides to guide surface, due to the setting of preceding hose, needle tubing becomes along guide surface
To avoiding penetrating blood vessel to make needle tubing is oblique to penetrate blood vessel；When hollow pipe enters and finds position in vivo, due to needle tubing
In hollow pipe, avoids and puncture other organs；The setting of rear hose keeps the movement of needle tubing more flexible, be also easier to and other
Component connection.
Preferably, the guiding wall is parallel with the hollow pipe axis.After so that operator is more preferably grasped needle tubing deflecting
Direction guarantees going on smoothly for blood sampling convenient for control acupuncture treatment direction.
Preferably, the diameter of the preceding hose is not more than the outer diameter of the interconnecting piece.Hose is in two guiding walls before avoiding
Between be squeezed, ensure that passing through for reliability that preceding hose is connected with interconnecting piece and blood.
Preferably, the front end face of the guide surface and interconnecting piece is compatible curved surface.By curved face contact, make needle tubing
Propulsion it is more smooth and smooth, further reduced the difficulty of acupuncture treatment, improve blood sampling efficiency.
The utility model has the following beneficial effects:, using hollow pipe as protection, avoiding accidental injury when needle tubing enters internal
Other organs when acupuncture treatment, are changed the direction of needle tubing by guide surface, make needle tubing is oblique to penetrate blood vessel, avoid and penetrate blood vessel,
It ensure that going on smoothly for blood sampling.

Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
Venous blood-taking apparatus under a kind of varied angle hysteroscope as shown in Figure 1, including casing 1 and blood taking needle 2.
Blood taking needle 2 includes the stainless steel needle tubing 201 being slidably connected in described sleeve pipe, and is sequentially connected from the needle tubing 201
Interconnecting piece 202, preceding hose 203, hard tube 204, rear hose 205 and female Luer 206, the outer diameter of the interconnecting piece 202 is greater than
The needle tubing outer diameter, the front end face of interconnecting piece 202, i.e., the end face connecting with needle tubing are curved surface, and the diameter of preceding hose 203 is not more than
The outer diameter of the interconnecting piece 202.
Casing 1 includes the sliding hollow pipe 102 for having the needle tubing and the syringe needle for being fixed in 102 front end of hollow pipe guidance
Portion 101, the syringe needle guide portion 101 are equipped with the guide surface 105 extended towards hollow pipe axis, open in the guide surface 105
Equipped with the through slot 104 being adapted to the needle tubing, 104 two sides of through slot are equipped with guiding wall 103, the spacing of two sides guiding wall and company
Socket part outer diameter adaptation, and guiding wall 103 is parallel with the axis of hollow pipe 102.In order to keep the promotion of needle tubing more smooth, the present embodiment
