Description
Technical field
The utility model relates to remaining needle technical field more particularly to a kind of venous detaining needles.
Background technique
Carrying out infusion using venous detaining needle is the preferable method of clinical transfusion, and venous detaining needle is easy to operate, is suitable for
The puncture at any position.Using venous detaining needle, it on the one hand can mitigate to puncture repeatedly and give infusion person's bring pain, another party
Face can mitigate the workload of nursing staff.
Fig. 1 is the structural schematic diagram of existing venous detaining needle.As shown in Figure 1, the hydrops in existing venous detaining needle
It is sharp compared with angle (angle A as shown in figure 1) between chamber 0 and the side of needle stand 0 '.Clinical use shows to flow through hydrops when medical fluid
When chamber 0, there is the phenomenon that cannot sometimes flowing through medical fluid at these more sharp angles, i.e., it is dead to have medical fluid for these regions
Angle, and air entrapment is easy in medical fluid dead angle, and be not easy to be discharged after air entrapment.
Summary of the invention
The purpose of this utility model is the angle solved between the side of the fluid collection chamber and needle stand in existing venous detaining needle
Degree is more sharp, causes easily to form medical fluid dead angle, so that venous detaining needle is easy air entrapment, and is not easy after air entrapment
The technical issues of discharge, provides a kind of venous detaining needle.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of venous detaining needle, including puncture needle, inlying catheter, needle stand, fluid collection chamber, extension tube, hold needle handle, batching pig and
Needle stand plug；
Inlying catheter is connect with the medical fluid delivery outlet of needle stand one end；Batching pig is set in needle stand inner cavity；Fluid collection chamber setting
In needle stand at the position of medical fluid delivery outlet, the fluid collection chamber is wheat head shape, and the liquid outlet of fluid collection chamber and inlying catheter
Inlet connection, the inlet of fluid collection chamber and the liquid outlet of extension tube connect；The tail end of needle stand plug and puncture needle connects and is located at
The tail portion of needle stand inner cavity, after the needle tip of puncture needle passes through batching pig, needle stand and fluid collection chamber, through medical fluid delivery outlet from inlying catheter
In be pierced by；Needle handle is held to connect with needle stand plug.
Optionally, liquid stopping clamp is provided in the extension tube.
Optionally, flow regulator is provided in the extension tube.
Optionally, the venous detaining needle further includes protective sleeve of syringe needle.
The beneficial effects of the utility model are:
By setting wheat head shape for fluid collection chamber, and the inlet for the liquid outlet and inlying catheter that fluid collection chamber is arranged connects,
The inlet of fluid collection chamber and the liquid outlet of extension tube connect, and not only making fluid collection chamber is streamlined, to make fluid collection chamber and liquid
The type of flow be adapted, and medical fluid is made to be directly entered fluid collection chamber from extension tube, medical fluid dead angle will not be formed in needle stand,
And then it can be to avoid air trapping in venous detaining needle.Therefore, compared with the background art, the utility model has structure simple
The advantages that rationally and can be avoided air trapping.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing venous detaining needle；
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with drawings and examples.
As shown in Fig. 2, the venous detaining needle in the present embodiment include puncture needle 1, inlying catheter 2, needle stand 3, fluid collection chamber 4,
Extension tube 5 holds needle handle 6, batching pig 7 and needle stand plug 8；Inlying catheter 2 is connect with the medical fluid delivery outlet of 3 one end of needle stand；Batching pig 7
It is set to the middle part of 3 inner cavity of needle stand；Fluid collection chamber 4 is set to needle stand 3 at the position of medical fluid delivery outlet, and the fluid collection chamber 4 is
Wheat head shape, and the liquid outlet of fluid collection chamber 4 is connect with the inlet of inlying catheter 2, the inlet of fluid collection chamber 4 and going out for extension tube 5
The connection of liquid mouth；Needle stand plug 8 connect and is located at the tail portion of 3 inner cavity of needle stand with the tail end of puncture needle 1, and the needle tip of puncture needle 1 passes through
After batching pig 7, needle stand 3 and fluid collection chamber 4, it is pierced by from inlying catheter 2 through medical fluid delivery outlet；Needle handle 6 is held to connect with needle stand plug 8.
Optionally, it is provided with liquid stopping clamp in the extension tube 5, starts or stops output medical fluid convenient for real-time control.
Optionally, it is provided with flow regulator in the extension tube 5, to adjust medical fluid flow velocity when infusion in real time, prevented
Hemostatic Oral Liquid reflux.
Optionally, the venous detaining needle further includes protective sleeve of syringe needle, to play protection when not using venous detaining needle
The effect of puncture needle 1.
When the utility model is used, hand holds needle handle 6 after exhaust, the syringe needle and skin for making puncture needle 1 are in 15~30 °
Angle is punctured, and after seeing blood back, reduces angle and puncture needle 1 is promoted 0.2~0.5cm again.Then, the fixed inlying catheter 2 of the right hand,
Left hand hand holds needle handle 6 and extracts 10.5~1cm of puncture needle, and inlying catheter 2 is all sent into vein, loose arm-rest belt.Next,
Left-handed needle handle 6 extracts needle stand plug 8 out, after puncture needle 1 is completely drawn out, fixes venous detaining needle with Special applicator.
