Abstract
The utility model relates to an it is a keep somewhere needle for taking spiral pressfitting formula malleation device particularly to doctors and nurses articles for use technical field, including infusion joint, extension hose, pjncture needle, puncture needle file and tubing assembly, the infusion connects through lengthening hose connecting catheters seat, its characterized in that the extension hose on be equipped with the malleation device, the inside cavity that is equipped with of malleation device, the hose passes this cavity, cavity upper portion is equipped with spiral compression fittings, spiral compression fittings upper portion is equipped with the handle, the handle lower part is equipped with the screw thread depression bar, the screw thread depression bar passes through threaded connection with the malleation device. The utility model discloses accomplish the back in the infusion, the handle through rotatory vertical closing device advances the malleation device, makes the liquid in the hose flow to the pipe front end, makes the pipe front end have liquid to flow out, and blood retains and form the embolism in the pipe when avoiding infuse next time, and the tube sealing is effectual, the simple operation, lengthened and keep somewhere the time effectively.
Description
[technical field]
This utility model relates to technical field of medical instruments, be specifically related to a kind of for using venous detaining needle infuse time, solution inlying catheter and the infusion set time of releasing produce negative pressure and occur blood back for the remaining needle with spiral laminated type positive pressure devices.
[background technology]
Existing venoclysis needle is easy piercing blood vessel in infusion process, must change at every turn.The invention of venous detaining needle and application overcome these shortcomings, need nook closing member to extract out during use after completing venipuncture, only leave sleeve pipe, so can not injured blood vessel, can stay Ink vessel transfusing continuously with several days.Meanwhile, the use of venous detaining needle can also reduce patient because of venipuncture repeatedly and the misery caused, and alleviate the workload of nurse simultaneously, be convenient to clinical application, thus venous detaining needle is used widely clinically.
Existing venous detaining needle, in its extension tube, all cover has flow-stopping clip.During normal infusion, flow-stopping clip is in open mode, coordinates calparine cap or end cap to infuse by noting defeated device; When needs suspend transfusion, apply external force and fluid stopping clamping is closed, extension tube clamps and makes extension tube be in disconnection state by the boss in flow-stopping clip.The mode that this kind suspends transfusion be direct clamping mode rapidly, usual flow-stopping clip is semi-steel plastic material manufacture, due to the elastic reaction of plastics while directly clamping, make with the conduit of sick body contact position in produce negative pressure, thus cause the conduit be retained in human body to produce blood back, this blood back produces blood coagulation in inlying catheter at known causing, form the immediate cause of thrombosis or blocking, these blood coagulation bolts are hidden in inlying catheter end, be hidden in us and opaque Ink vessel transfusing, naked eyes cannot directly be observed and relatively hidden, affect follow-up transfusion, even if pressurization is washed open, thrombosis also may block blood capillary, even cause vasculitis, cause unnecessary malpractice.
Cause plugging in order to avoid blood backflow to pin, slowly injection positive pressure tube sealing method or malleation fluid stopping device positive pressure tube sealing be adopted, but existing malleation fluid stopping apparatus structure is complicated, expensive.
[summary of the invention]
This utility model is to solve the problem, there is provided a kind of simple to operate, blood back problem during simultaneously solving indwelling, not only while possessing malleation performance but possess avoid indwelling during because of blood back, and cause blood coagulation, blocking, thus shorten the technical problem of indwelling time, design a kind of novel structure band for the remaining needle with spiral laminated type positive pressure devices.
To achieve these goals, design a kind of for the remaining needle with spiral laminated type positive pressure devices, comprise infusion connector, extend flexible pipe, puncture needle, Paracentesis needle holder and conduit tube component, infusion connector is by extending hose connection catheter block, it is characterized in that described prolongation flexible pipe is provided with positive pressure devices, described positive pressure devices inside is provided with cavity, flexible pipe is through this cavity, cavity top is provided with spiral press fit device, spiral press fit device top is provided with handle, lower portion thereof is provided with screw thread depression bar, and screw thread depression bar and positive pressure devices are threaded connection.
This utility model compared with the existing technology, its advantage is: after transfusion completes, positive pressure devices is advanced by the handle of spiral press fit device, flowed in liquid conductive pipe front end in flexible pipe, catheter proximal end is made to have liquid to flow out, when avoiding transfusion next time, blood remains in conduit and forms thromboembolism, and tube sealing is effective, simple operation, effectively extend indwelling time.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
As shown in Figure 1, comprise infusion connector for the infusion pipeline in the remaining needle with longitudinal compression type positive pressure devices, extend flexible pipe, puncture needle and Paracentesis needle holder, infusion connector, by extending hose connection puncture needle and Paracentesis needle holder, extends flexible pipe and is provided with positive pressure devices.
The concrete structure figure of positive pressure devices is see Fig. 2, and positive pressure devices inside is provided with cavity, and flexible pipe is through this cavity, cavity top is provided with spiral press fit device, spiral press fit device top is provided with handle, and lower portion thereof is provided with screw thread depression bar, and screw thread depression bar and positive pressure devices are threaded connection
After having infused at every turn, positive pressure devices is advanced by the handle rotating longitudinal hold down gag, as Fig. 3, flowed in liquid conductive pipe front end in prolongation flexible pipe, make catheter proximal end have liquid to flow out, liquid flows through cavity through extending flexible pipe, and positive pressure devices is opened, liquid inflow port is cavity entrance point, and liquid flowing outlet is cavity exit end.
