Abstract
The invention relates to a hydraulic dropper special for skin prick tests. The hydraulic dropper comprises a sucker and a suction bag, the sucker and the suction bag are through, the suction bag is made of elastic materials, can be deformed in the stress state, and can get back into shape after stress is removed, and a dropper shell is arranged outside the suction bag and is a stepped tube, wherein the head of the stepped tube is thick, and the tail of the stepped tube is thin; a piston is arranged at the tail of the suction bag and divides the thick part of the tube into a left area and a right area, the suction bag is fixed into the right area of the thick part of the tube, the left area is communicated with the thin part of the tube and filled with liquid or emulsus solid-liquid mixtures, a sealing ring is arranged inside the tail end of the thin part of the tube, a push rod is connected to the tail of the sealing ring, a dustproof cover is arranged outside the tail end of the thin part of the tube, and dust can be prevented from entering the thin part of the tube.
Description
Technical field
The present invention relates to a kind of dropper, particularly relate to a kind of hydraulic pressure dropper being exclusively used in skin prick experiment.
Background technology
The test of existing human body skin allergy, mainly tested by skin prick and obtain desired data, what the current experiment of skin prick clinically mainly adopted is the test of skin prick anaphylactogen medicinal liquid---patient's bilateral forearm of sterilizing, inner forearm anaphylactogen medicinal liquid (about 20 kinds) on 3-5cm drips, and drip have Skin prick testing and normal saline negative control, in the medicinal liquid central authorities vertical prick skin of disposable aspiration needle to subcutaneous, observe 20 minutes, comparing with histamine group and saline group, there is position and size in record welt.But for medical personnel, in the process of dripping original liquid, often there will be dripped original liquid too many; original liquid sucks back in dropper by medical personnel, causes dropper head to touch patient skin, uses then to next patient; easily cause cross infection, there is potential safety hazard.Because experiment original liquid manufacturing cost is high, in order to save original liquid, therefore detecting medical personnel and can not let go when operating, oozing appropriate original liquid difficulty comparatively large, make whole detection time long.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and accurately can control to ooze fast, the safe hydraulic pressure dropper being exclusively used in skin prick experiment of original liquid, detection efficiency.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of hydraulic pressure dropper being exclusively used in skin prick experiment, comprise suction pipe and inhale capsule, described suction pipe is connected connects with suction capsule, inhaling capsule adopts elastomeric material to make, can deformation be there is in stress, remove stressed after can restore to the original state, inhale capsule outside and be provided with dropper housing, dropper housing is stepped pipeline and head be extra heavy pipe road afterbody is thin pipe, inhale capsule afterbody and be provided with a piston, extra heavy pipe road is set to two and is separated into two regions, left and right by piston, inhaling capsule is fixed in the right region in extra heavy pipe road, left region and thin pipe are connected, built with liquid or emulsus solidliquid mixture, thin pipe terminus inner is provided with sealing ring, sealing ring afterbody connects push rod, thin pipe exterior end is provided with dust cap, dust can be avoided to enter thin pipe.
The invention provides a kind of beneficial effect of hydraulic pressure dropper being exclusively used in skin prick experiment is: after design promotes push rod like this, the liquid of thin pipe can be expressed in extra heavy pipe road thus to promote piston compression suction capsule by sealing ring, inhale after capsule is compressed and the liquid of dropper can be extruded dropper, the sensitivity of dropper can adjust according to the area ratio of extra heavy pipe road and thin pipe, the original liquid that can realize dripping comparatively accurately according to the push-in stroke of thin pipe is like this just in time the capacity needed for test, and the capacity realizing each original liquid drippage reaches the equal of degree of precision.
Further, thin pipe, built with machine oil, can reduce the resistance of promotion like this.
Further, extra heavy pipe is provided with spring in road, and one end connects piston, and one end connects tube wall, can ensure like this to inhale capsule automatic rebounding.
Further, housing adopts transparent material to make, and can observe the propelling situation of piston intuitively.
Accompanying drawing explanation
Fig. 1 is a kind of hydraulic pressure dropper schematic diagram being exclusively used in skin prick experiment of the present invention;
Detailed description of the invention
As required, disclosed herein specific embodiment of the present invention, but should be appreciated that the disclosed embodiments are just demonstrated the present invention, the present invention can different and alternative form enforcement.Accompanying drawing may not proportionally be drawn, and some feature can be exaggerated or reduce to illustrate the details of particular elements.Therefore, concrete structure disclosed herein and function detail should not be understood to have limited significance, but only representatively property is basic to instruct those skilled in the art differently to adopt the present invention.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of hydraulic pressure dropper being exclusively used in skin prick experiment, comprise suction pipe 1 and inhale capsule 2, described suction pipe 1 is connected connects with suction capsule 2, inhaling capsule 2 adopts elastomeric material to make, can deformation be there is in stress, remove stressed after can restore to the original state, inhale capsule 2 outside and be provided with dropper housing 3, dropper housing 3 is thin pipe 6 for stepped pipeline and head are extra heavy pipe road afterbody, inhale capsule 2 afterbody and be provided with a piston 4, extra heavy pipe road is set to two and is separated into two regions, left and right by piston 4, inhaling capsule 2 is fixed in the right region in extra heavy pipe road, left region 5 is connected with thin pipe 6, built with liquid or emulsus solidliquid mixture 7, thin pipe 6 terminus inner is provided with sealing ring 8, 8, sealing ring tail connects push rod 10, thin pipe 6 exterior end is provided with dust cap 9, dust can be avoided to enter thin pipe 6.
As shown in Figure 1, thin pipe 6, built with machine oil, can reduce the resistance of promotion like this.
As shown in Figure 1, extra heavy pipe is provided with spring in road, and one end connects piston 4, and one end connects tube wall, can ensure like this to inhale capsule 2 automatic rebounding.
As shown in Figure 1, dropper housing 3 adopts transparent material to make.
