Abstract
The invention relates to the field of an injector, in particular to a low-pressure needle-free injection device capable of enabling liquid medicine to be jetted in an atomized shape, which comprises a needle-free injection device body, wherein the front of the needle-free injection device body is provided with a front lumen assembly, the left side end of the front lumen assembly is connected with an injection port assembly, the upper part of the left side end of the front lumen assembly is provided with a lumen assembly, and the front lumen assembly is internally provided with an injection push rod assembly. The low-pressure needle-free injection device also comprises a magnetic push rod assembly, wherein the magnetic push rod assembly is arranged in the front lumen assembly, one end of the magnetic push rod assembly is connected with the injection port assembly, and the other end of the magnetic push rod assembly is connected with the injection push rod assembly. The low-pressure needle-free injection device is simple and convenient to operate, reasonable in structure, and can not cause pain and damage the skin.
Description
Technical field
The present invention relates to the Needleless injection technical field, particularly a kind of low-pressure can make medicinal liquid be the Needleless injection device of atomized spray.
Background technology
Social development has also brought scientific and technological progress, and syringe is also from there being needle applicator to develop into needleless injector, the needleless injector injection is without syringe needle, it adopts superpowerful special spring that medicinal liquid is formed superfine liquid bundle by ampoule bottle and is pressed into skin, the injection persistent period is short, and is painless, noiseless, safety is quick; Needleless injector has been compared needle applicator, can reduce cross infection, avoid the injection point damage, can repeat the advantages such as rapid and convenient use, so now medical common safe and reliable needleless injector, but there are the following problems for present needleless injector: existing needleless injector is for guaranteeing that medicinal liquid all injects human body inside, general pressure all is higher than 2000psi, though this high-intensity pressure can make injecting liquid drug enter human body, but high pressure not only can not reduce patient's pain, also human body is caused the blue or green damage that waits in various degree of becoming silted up, can not guarantee that again medicinal liquid all enters human body but pressure is too low.So human body is not produced damage again when how to reduce liquid medicine injection, it is the problem that the present invention must solve.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, provide a kind of simple in structure, a kind of low-pressure reasonable in design, easy to use can make medicinal liquid be the Needleless injection device of atomized spray, when its adopts magnetic push-rod assembly that pressure is adjusted to 150psi by behind injection port and the injection putter again through MIT series low pressure needleless injector with disposable injection head effect make medicinal liquid be countless micropin shape miniflows then under the effect of the utmost point low-pressure transdermal enter human body, it is simple to operation, rational in infrastructure, painless and can injured skin.
For achieving the above object, the technical solution used in the present invention is:
A kind of low-pressure of the present invention can make medicinal liquid be the Needleless injection device of atomized spray, comprises the needle-less injection devices body, and described needle-less injection devices body portion is provided with front lumen assembly; Described front lumen assembly left-hand end links to each other with the injection port assembly; Described front lumen assembly left-hand end top is provided with barrel assembly; Be provided with the injection putter assembly in the described front lumen assembly; It also comprises the magnetic push-rod assembly, and described magnetic push-rod assembly is arranged in the front lumen assembly; Described magnetic push-rod assembly one end links to each other with the injection port assembly; The described magnetic push-rod assembly other end links to each other with the injection putter assembly.
Further, described injection port assembly port is provided with disposable injection head; Described disposable injection head port surface is circular, and the cross section of disposable injection head is tapered micro holes.Described under the thrust of magnetic push-rod assembly, can make medicinal liquid in the injection device produce enough pressure with medicinal liquid rapidly by gun barrel, then at disposable injection port place by behind the tapered micro holes with fine and closely woven vaporific ejection.
After adopting said structure, beneficial effect of the present invention is: when the present invention adopts the magnetic push-rod assembly that pressure is adjusted to 150psi by behind injection port and the injection putter again through MIT series low pressure needleless injector with disposable injection head effect make medicinal liquid be countless micropin shape miniflows then under the effect of the utmost point low-pressure transdermal enter human body, it is simple to operation, rational in infrastructure, painless and can injured skin.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of low-pressure of the present invention can make medicinal liquid be the Needleless injection device of atomized spray, comprises needle-less injection devices body 1, and described needle-less injection devices body 1 front portion is provided with front lumen assembly 5; Described front lumen assembly 5 left-hand end link to each other with injection port assembly 4; Described front lumen assembly 5 left-hand end tops are provided with barrel assembly 2; Be provided with injection putter assembly 3 in the described front lumen assembly 5; It also comprises magnetic push-rod assembly 6, and described magnetic push-rod assembly 6 is arranged in the front lumen assembly 5; Described magnetic push-rod assembly 6 one ends link to each other with injection port assembly 4; Described magnetic push-rod assembly 6 other ends link to each other with injection putter assembly 3.
Be provided with disposable injection head as a kind of preferred described injection port assembly of the present invention 4 ports; Described disposable injection head port surface is circular, and the cross section of disposable injection head is tapered micro holes.Described under the thrust of magnetic push-rod assembly 6, can make medicinal liquid in the injection device produce enough pressure with medicinal liquid rapidly by gun barrel, then at disposable injection port place by behind the tapered micro holes with fine and closely woven vaporific ejection.
When the present invention adopts the magnetic push-rod assembly that pressure is adjusted to 150psi by behind injection port and the injection putter again through MIT series low pressure needleless injector with disposable injection head effect make medicinal liquid be countless micropin shape miniflows then under the effect of the utmost point low-pressure transdermal enter human body.
It is simple to operation, rational in infrastructure in the present invention, and is painless and can injured skin.
The above only is preferred embodiments of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
