Abstract
The utility model discloses a spiral infusion extension tube, including the outer tube, be equipped with the inner tube in the outer tube, the both ends of inner tube are equipped with syringe needle connector and syringe connector respectively, the outer tube is hollow heliciform sleeve, the inner tube cover is established at the outer tube and is fixed into whole with the outer tube, and the end of outer tube is stretched out respectively at the inner tube both ends. The extension tube of helical shape has the flexible characteristics of spiral, even length extension can not cause the winding yet, is fit for multiple injection condition, and convenient observation again can safer better apply to clinically.
Description
Technical Field
The utility model relates to the technical field of medical auxiliary equipment, in particular to a spiral transfusion extension tube.
Background
The use of extension tubes is very common in hospital wards and in neonatology. The patient is coma and restless, and limbs mobility is big, leads to keeping somewhere that the needle position is unsettled (especially children's intensive care unit, and head, hand, foot and groin department often keep somewhere), and the extension pipe length of existing use is short a bit relatively, often causes to keep somewhere the needle and drops or the transfer pump is askew to fall, for this reason, will increase an extension pipe again, but in addition afterwards, length is too long again, will cause the pipeline winding again, or is pressed the body by the patient and is difficult for observing under, causes adverse effect to the patient.
Disclosure of Invention
In order to solve the problems, the application provides a spiral transfusion extension tube, which can increase or reduce the length according to actual needs without causing winding and is convenient to observe.
The technical scheme of the application is as follows:
the utility model provides a spiral infusion extension tube, its characterized in that includes the outer tube, be equipped with the inner tube in the outer tube, the both ends of inner tube are equipped with syringe needle connector and syringe connector respectively, the outer tube is hollow heliciform sleeve, the inner tube cover is established in the outer tube and is fixed into an organic whole with the outer tube, and the end of outer tube is stretched out respectively at inner tube both ends.
Furthermore, the two ends of the outer sleeve are respectively provided with a sealing ring, and two surfaces of each sealing ring are respectively fixedly connected with the outer sleeve and the inner pipe.
Furthermore, an internal thread is arranged in the needle connecting port.
Furthermore, the outer sleeve is made of polyvinyl chloride material, and the inner pipe is made of high-performance polyolefin thermoplastic elastomer material.
The beneficial effect of this application does:
the extension tube of helical shape has the flexible characteristics of spiral, even length extension can not cause the winding yet, is fit for multiple injection condition, and convenient observation again can safer better apply to clinically.
Drawings
Fig. 1 is a schematic structural diagram of the present application.
In the figure: the outer sleeve 1, the inner tube 2, the needle head connecting port 3, the injector connecting port 4, the sealing ring 5 and the internal thread 6.
Detailed Description
The present application is further described with reference to the following description and detailed description of the preferred embodiments.
The utility model provides a spiral infusion extension tube, its characterized in that, includes outer tube 1, be equipped with inner tube 2 in the outer tube 1, the both ends of inner tube 2 are equipped with syringe needle connector 3 and syringe connector 4 respectively, outer tube 1 is hollow heliciform sleeve, 2 covers of inner tube are established in outer tube 1 and are fixed into whole with outer tube 1, and the end of outer tube 1 is stretched out respectively at 2 both ends of inner tube, outer tube 1 and inner tube 2 are the transparent plastic material and make, because the flexible characteristics of spiral, can not cause the winding yet, convenient observation again.
Furthermore, both ends of the outer sleeve are provided with sealing rings 5, two surfaces of each sealing ring 5 are fixedly connected with the outer sleeve 1 and the inner tube 2 respectively, and the inner tube 2 and the outer sleeve 1 are fixed by the sealing rings 5 to form a whole.
Furthermore, the needle head connecting port 3 is internally provided with an internal thread, so that the connection firmness can be increased, and the internal thread can be connected with a scalp needle and a vein indwelling needle.
Furthermore, the outer sleeve 1 is made of polyvinyl chloride material, the inner tube 2 is made of high-performance polyolefin thermoplastic elastomer material, and the two materials have dull surfaces, soft properties and good extensibility.
When the extension tube is used, one end of the extension tube is connected with the injector, the other end of the extension tube is connected with the scalp needle, the extension tube in the spiral shape is lengthened, winding cannot be caused due to the spiral telescopic characteristic, observation is convenient, the extension tube is made of TPE (thermoplastic elastomer) which is high in transparency and completely does not absorb medicines, but is made of soft materials and high in spiral difficulty, and therefore the extension tube is additionally provided with the spiral outer sleeve which is made of PVC (polyvinyl chloride) which is low in price and good in elasticity, has an adsorption effect on the medicines but does not contact with the medicines as the outer sleeve, can achieve a telescopic effect, and is safer and better to apply to clinic.
The above is only the embodiment of the present invention, not limiting the scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the present invention, or directly or indirectly applied to other related technical fields, and all included in the same way in the protection scope of the present invention.
