Abstract
A chuck dropper special for a skin prick test comprises suction pipe and a suction bag which are communicated. The suction bag is made of elastic material. The suction bag can deform when being stressed and can recover when not being stressed. A left clamp plate and a right clamp plate are fixed outside the suction bag. The left clamp plate and the right clamp plate are hinged to one point and can rotate around the same shaft. When the left clamp plate and the right clamp plate move towards each other, the suction bag is squeezed to discharge liquid or gas in the suction bag, and the suction bag recovers when the left clamp plate and the right clamp plate stretch.
Description
Technical field
The present invention relates to a kind of dropper, more particularly, to a kind of chuck dropper being exclusively used in skin prick experiment.
Background technology
Existing human body skin allergy test, mainly tests to obtain desired data by skin prick, clinical at present
Upper skin prick experiment mainly uses skin prick allergy original liquid test sterilization patient's bilateral forearm, in forearm
A upper allergy original liquid (about 20 kinds) is dripped every 3-5cm in side, and drip have Skin prick testing and normal saline negative control,
Medicinal liquid central authorities disposable aspiration needle perpendicular insertion broken skin skin, to subcutaneous, observed 20 minutes, is compared with histamine group and saline group, record wind
Position and size in group.But for medical personnel, during dripping original liquid, often occur that dripped original liquid is too many,
Medical personnel suck back original liquid in dropper, cause dropper head to touch patient skin, use then to next patient, hold
Easily cause cross infection, there is potential safety hazard.Because experiment original liquid manufacturing cost is high, in order to save original liquid, therefore detect
Medical personnel can not let go in operation, and it is larger to ooze appropriate original liquid difficulty, makes whole detection time long.
Content of the invention
The technical problem to be solved is: provides one kind can accurately control and oozes that original liquid, detection efficiency be fast, peace
The full chuck dropper being exclusively used in skin prick experiment.
For solving above-mentioned technical problem, the present invention employs the following technical solutions: a kind of folder being exclusively used in skin prick experiment
Head dropper, includes suction pipe and inhales capsule, described suction pipe is connected and connects with suction capsule, suction capsule is made using elastomeric material, stress
Can deform upon, can restore to the original state after removing stress, inhaling capsule external stability has left clamping plate and right clamping plate, left clamping plate and right clamping plate hinge
It is connected to any to rotate around same axle, extruding when left and right clamping plate is mutually drawn close is inhaled capsule and will be inhaled intracapsular liquid or gas extrusion, left
Inhale capsule when right clamping plate opens and recover shape.
A kind of beneficial effect of the chuck dropper being exclusively used in skin prick experiment of present invention offer is: so designs compression clip
Plate two ends can extrude inhales capsule, inhales and the liquid of dropper can be extruded dropper after capsule is compressed, the effect that clamping plate plays regulations and parameters is so big
The big sensitivity increasing dropper, the original liquid that so can very easily realize dripping is exactly to test required capacity, and
The capacity of original liquid drippage is equal every time.
Further, preferably, left clamping plate is provided with a circular arc positive stop strip, positive stop strip is provided with stopper slot, spacing
It is provided with limiting tooth, limiting tooth carries wedge angle for head and unified makes the object of movement in groove can only be along towards certain orientation in groove
Wedge angle direction is moved, and right clamping plate relevant position is provided with installing plate, and equipped with banking pin on installing plate, in the middle part of banking pin, width is more than upper
Portion and bottom allow insertion stopper slot in the middle part of banking pin be stuck on limiting tooth by banking pin move down rear banking pin top with
The concordant limiting tooth of stopper slot is not contacted with banking pin and banking pin is freely slided, equipped with bullet on banking pin bottom in groove
Spring, withstands the installing plate that in the middle part of banking pin, lower section is withstood on clamping plate above spring, the end of banking pin bottom is more than under banking pin
Portion, banking pin top is provided with pressing board, so presses pressing board, and left clamping plate and right clamping plate just can slowly flick, the limit in stopper slot
Position tooth is matched with banking pin, realizes the effect that the unidirectionally extruded retaining in direction of capsule inhaled by left clamping plate with right clamping plate along clamping extruding,
Need left clamping plate is relative with right clamping plate open when it is only necessary to by installing plate upper limit follow closely pressing board press down on, make banking pin
Top move to and limiting tooth cooperation position, and banking pin top do not contact with banking pin it is impossible to banking pin clamping limit
Position, now left clamping plate and right clamping plate can realize inhaling capsule diastole along opening direction relative movement, and banking pin bottom and spring
Setting can facilitate banking pin to install on a mounting board, and up and down along installing plate, realizes the clamping of limiting tooth and banking pin
Whether.
Further, the afterbody looped-shaped bending of left clamping plate and right clamping plate makes finger may be inserted in ring, such knot
Structure can be extruded moreover it is possible to play the effect holding on hand when can more firmly have an effect in finger insertion ring with convenient use.
Further, positive stop strip is provided with scale, so can be further observed that the amount oozing liquid.
Further, suction pipe is made up of transparent glass material, and the flowing of liquid can conveniently be observed by transparent suction pipe, with
Just control the amount of dripping.
