Abstract
The utility model belongs to a medical transfusion device, in particular to a venous transfusion detaining needle, which comprises a soft detaining pipe, a transfusion connecting pipe and a rubber plug, wherein the transfusion connecting pipe is communicated with the soft detaining pipe, the rubber plug is positioned in a cavity of the tail end of the soft detaining pipe, liquid side outlets are arranged on the pipe wall of the front end of the soft detaining pipe with the distance of 1mm to 5mm away from a port of the front end, a plurality of liquid side outlets decompose the liquid outlet pressure of the port of the front end of the soft detaining pipe in different directions, the structure is structure and practical, the problem of larger pressure generated on the blood vessel wall caused by fast injection speed in the venous transfusion process is solved, and the pain of the injection part and the injury on the blood vessel wall can be relieved.
Description
Technical field
This utility model belongs to a kind of medical infusion equipment, is specifically related to a kind of venous transfusion remaining needle.
Background technology
Medical venous transfusion remaining needle generally comprises the transfusion indwelling tube that nontoxic plasticity soft material is made at present, and indwelling tube is just directly stayed the inside as tube for transfusion after being brought into human vas by the rigidity syringe needle.In various gravity type or pressure type intravenous injection and transfusion process, for example use high pressure injector in human body, to inject contrast agent, injection speed commonly used is a per second 2-4 milliliter, particularly when perfusion, general injection speed is 6 milliliters of per seconds, even reach 8 milliliters of per seconds, fast like this injection speed can produce bigger pressure to blood vessel wall, easily cause the patient vessel to damage and local pain, particularly more serious to the intravenous patient vessel's damage of repeated multiple times, for the pain that alleviates the injection site and the damage of blood vessel wall, be necessary existing venous transfusion remaining needle is improved.
The utility model content
For solving in the venous transfusion process, injection speed produces the problem of bigger pressure soon to blood vessel wall, alleviate the pain of injection site and this technical problem of damage of blood vessel wall, this utility model by the following technical solutions, a kind of venous transfusion remaining needle promptly is provided, comprise soft indwelling tube, the transfusion connection tube that communicates with soft indwelling tube and the rubber plug that is positioned at soft indwelling tube end cavity, be provided with the hydraulic fluid side apart from front end port one mm～5mm place on the soft indwelling tube front end tube wall and portal.
When in human body, carrying out the liquid conveying, under the bigger situation of pressure, if do not reduce pressure, the impulsive force that liquid concentrates on a direction makes patient's vein blood vessel inwall be subjected to greater impact power, cause the patient vessel to damage and local pain, particularly more serious to the intravenous patient vessel's damage of repeated multiple times.Different with existing indwelling tube, the venous transfusion remaining needle that this utility model provides is provided with the hydraulic fluid side apart from front end port one mm～5mm place and portals on described soft indwelling tube front end tube wall, side is portalled and can be shunted institute's injecting fluid, significantly reduce the impulsive force of the liquid of input, alleviated patient vessel's damage and local pain to local vessel wall.And portalling in the hydraulic fluid side has certain distance apart from soft indwelling tube front end port, be to do the time spent hydraulic fluid side and portal approachingly, do not have the effect that alleviates patient vessel's damage and local pain with the local location of soft indwelling tube front port effect in order to prevent to be subjected in the infusion process big pressure; Simultaneously, if portal in the hydraulic fluid side after the leaning on of being provided with, then side is portalled and is trapped in easily outside the human vas, can not all be inputed in the blood vessel by transfusion, and obvious so also is inappropriate.
Further, on the basis of above-mentioned design, can a plurality of hydraulic fluid sides be set on the tube wall of soft indwelling tube front end and portal, as much as possible injection pressure be decomposed.
Further, described a plurality of hydraulic fluid side is portalled staggered on the indwelling tube tube wall, be a plurality of hydraulic fluid sides portal be not along with soft indwelling tube centrage parallel lines arranged distribution, neither be arranged evenly on the vertical same circumferential plane of soft indwelling tube centrage, can go up from different directions like this and decompose pressure that blood vessel wall is born, prevent that local vessel wall is subjected to stronger resonating pressure.
Obviously, the hydraulic fluid side is portalled many more, and pressure is dispersive good more, and the aperture of portalling in the hydraulic fluid side is more little, and the pressure that the blood vessel part is born is more little.Therefore, further restriction, described hydraulic fluid side goes out half that pore diameter size is soft indwelling tube front end port diameter size.
This utility model is the output liquid pressure that utilizes a plurality of hydraulic fluid sides to portal to decompose from different directions soft indwelling tube front end port, scheme compared to existing technology, and the damage that alleviates the pain and the blood vessel wall of injection site, simple, practical.
Description of drawings
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated:
Fig. 1 is a kind of intravenous injection indwelling tube sketch map that this utility model provides;
Fig. 2 is the enlarged diagram of A among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, this utility model provides a kind of venous transfusion remaining needle, comprise soft indwelling tube 1, the transfusion connection tube 2 that communicates with soft indwelling tube 1 and the rubber plug 3 that is positioned at soft indwelling tube 1 end cavity, be provided with 3 hydraulic fluid sides apart from front end port one mm place on the soft indwelling tube 1 front end tube wall and portal 4, portal 4 diameter of hydraulic fluid side is half of soft indwelling tube 1 front end port diameter size, and it is 4 staggered around soft indwelling tube 1 front end tube wall to portal in 3 hydraulic fluid sides.
Above-described only is preferred implementation of the present utility model, should be understood that, for a person skilled in the art, under the prerequisite that does not break away from this utility model structure, can also make some distortion and improvement, such as side portal 4 positions that are provided with can be on the soft indwelling tube 1 front end tube wall apart from front end port one mm place, also can be 5mm place, 3mm place; Portal 4 diameter and quantity of hydraulic fluid side also can suitably be provided with, and these also should be considered as protection domain of the present utility model.
