Description

Dropping device

Technical Field

The present invention relates to a drip device.

Background

The prior human skin allergy test mainly obtains required data through a skin pricking experiment, the skin pricking allergen liquid medicine test is mainly adopted in the clinical skin pricking experiment at present, namely, the double-side forearms of a patient are disinfected, about 20 allergen liquid medicines are dripped on the inner side of the forearms every 3 cm to 5cm, histamine positive control and physiological saline negative control are dripped on the inner side of the forearms, the skin is pricked to the skin to the lower side vertically by a disposable needle head in the center of the liquid medicine, the skin pricking allergen liquid medicine is observed for 20 minutes, and compared with a histamine group and a saline group, the appearance position and the appearance size of wind clusters are recorded. However, for medical staff, in the process of dripping the original liquid medicine, too much of the original liquid medicine is frequently dripped, the original liquid medicine is sucked back into the dropper by the medical staff, so that the dropper head touches the skin of a patient, then the medical staff is used for the next patient, cross infection is easy to cause, and potential safety hazards exist. Because the manufacturing cost of the experimental original liquid medicine is high, in order to save the original liquid medicine, the detection medical staff cannot put the liquid medicine in operation, and the difficulty of dripping an appropriate amount of the original liquid medicine is high, so that the whole detection time is overlong.

Disclosure of Invention

The technical problems to be solved by the invention are as follows: the liquid dropping device is quick in detection efficiency and safe and is specially used for skin prick experiments.

In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a dropping liquid device, includes stock solution part and picture peg, be equipped with a plurality of stock solution holes and many water conservancy diversion recesses on the stock solution part, be equipped with the drainage head that reduces gradually from top to bottom on the stock solution part, be equipped with the drainage groove on the drainage head, stock solution hole, water conservancy diversion recess and drainage groove are linked together, be equipped with the arch on the picture peg, the arch on the picture peg is inserted and is established on the water conservancy diversion recess on the stock solution part for the picture peg can reciprocate on the stock solution part, stock solution hole and water conservancy diversion recess on the stock solution part are all covered sealedly by the picture peg, and relative stock solution part of picture peg shifts up, is covered sealed stock solution hole and water conservancy diversion recess by the picture peg and exposes, and the downflow water droppings of liquid of storing in the stock solution hole.

The liquid dropping device provided by the invention has the beneficial effects that: when the device is used for testing, the plugboard is pulled upwards firstly, the plugboard is enabled to move upwards relative to the liquid storage part, the liquid storage hole on the liquid storage part is enabled to be exposed completely, then the liquid storage part is placed into raw liquid medicine, the raw liquid medicine flows into the liquid storage hole, the plugboard is then moved downwards, the liquid storage hole on the liquid storage part and the diversion groove are covered and sealed by the plugboard, so that the raw liquid medicine is stored in the liquid storage hole, the liquid storage hole is finally placed above the skin to be tested, one hand of a medical person holds the liquid storage part, the plugboard is pulled upwards by the other hand of the medical person, the plugboard is covered and the diversion groove is exposed, the raw liquid medicine stored in the liquid storage hole flows downwards and flows through the diversion groove and the diversion groove to be dripped on the skin to be tested of a patient, therefore, when a plurality of raw liquid medicine is required to be dripped, only the plugboard is required to be pulled upwards, the liquid medicine is required to be exposed to be a plurality of liquid storage holes, the capacity required to be tested is just equal, the capacity required for each time of raw liquid medicine dripping is required to be dripped, the process is repeated, and the process is repeated during the test, so that the medical person is required to be tested, the medical person is required to be in the liquid medicine to be dripped, the process is not to hold the liquid medicine in the liquid storage part, the liquid medicine is required to be tested, and the liquid is required to be tested, and the human is required to be more easily, and has the liquid to be more and has the medical liquid to be more easily and has the medical liquid and easy and has the medical liquid and convenient to be required to be tested.

The invention provides a dropping device which is further described in detail below with reference to the accompanying drawings and examples.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

As shown in fig. 1, 2 and 3, an embodiment of a dropping device provided by the invention comprises a liquid storage component 1 and an inserting plate 2, wherein a plurality of liquid storage holes 3 and a plurality of diversion grooves 4 are formed in the liquid storage component 1, a diversion head 6 which is gradually reduced from top to bottom is arranged on the liquid storage component 1, a diversion groove 7 is formed in the diversion head 6, the liquid storage holes 3, the diversion grooves 4 and the diversion groove 7 are communicated, a protrusion 5 is formed in the inserting plate 2, the protrusion 5 on the inserting plate 2 is inserted into the diversion grooves 4 on the liquid storage component 1, so that the inserting plate 2 can move up and down on the liquid storage component 1, the liquid storage holes 3 and the diversion grooves 4 on the liquid storage component 1 are covered and sealed by the inserting plate 2, and when the inserting plate 2 moves up relative to the liquid storage component 1, the liquid storage holes 3 and the diversion grooves 4 which are covered and sealed by the inserting plate 2 are exposed, and liquid stored in the liquid storage holes 3 flows downwards to drop.

As shown in fig. 1, 2 and 3, the diversion groove 4 on the liquid storage part 1 is a dovetail groove, and the protrusion 5 on the plugboard 2 is a trapezoid protrusion, so that the plugboard 2 can only move up and down relative to the liquid storage part 1, and the plugboard 2 is limited to move in the left-right direction, so that the plugboard 2 has better sealing effect of covering the liquid storage hole 3 and the diversion groove 4, and liquid seepage is prevented.
