The venom suction and discharge device is also an effective emergency treatment means for mild bee stings, gadflies, little bites (midges), poisonous snake bites and the like.
Description
Technical Field
The utility model belongs to the technical field of medical supplies, concretely relates to simple and easy worm venom suction and discharge device.
Background
Mosquito and ant bites and poisonous bees sting, poisonous liquid is injected into the human body, so that a lot of people feel itchy and painful, and even cause high anaphylactic reaction. If the venom can be sucked out as soon as possible by a suction method and then disinfected and antiallergic treatment is carried out, the symptoms can be relieved immediately, and even the effect of removing the diseases after the medicine is used is achieved. However, no related physical processing structure exists in the market of China at present, and the medicine processing is adopted; the foreign insect poison suction and discharge device extractor has the defects of high price, scarce market supply, excessive loss caused by mutual friction between the pumping rod and the sealing ring, and the problems of limited vacuum space of the needle cylinder and limited suction force sometimes. In particular, people in mountainous areas are often plagued by mosquitoes and threatened by poisonous bees, but can only endure the diseases.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a simple insect-biting venom suction and discharge device, which treats the toxin left in the skin after the insect bites in a true-hole negative pressure mode.
In order to realize the purpose, the utility model discloses a technical scheme is:
a simple venom suction and discharge device for insect bites comprises a needle cylinder (1), wherein a needle nozzle (2) below the needle cylinder (1) is connected with a butt joint pipe A (3), the butt joint pipe A (3) is connected with an air valve (4), the air valve (4) is connected with a connecting cover (6) through a butt joint pipe B (5), and a covering bowl (7) is connected below the connecting cover (6).
The air valve (4) is a one-way valve, a valve port A (8) and a valve port B (9) of the one-way valve are connected with the butt joint pipe A (3) and the butt joint pipe B (5), and a flexible necking (10) is arranged inside the one-way valve.
The edge of the bowl cover (7) can be sleeved with a soft sealing ring.
The utility model has the advantages that:
the structure can eliminate the itching symptom immediately through mosquito bite suction and discharge experiments. The venom suction and discharge device is also an effective emergency treatment means for mild bee stings, gadflies, little bites (midges), poisonous snake bites and the like, which occur when bees and wasps sting in China, and after the simple manufacturing method of the venom suction and discharge device is popularized, the pain of the public is expected to be relieved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the check valve of the present invention.
Wherein, 1 is a syringe; 2 is a needle mouth; 3 is butt joint pipe A; 4 is an air valve; 5 is butt joint pipe B; 6 is a connecting cover; 7, covering a bowl; 8 is a valve port A; 9 is a valve port B; 10 is flexible.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the simple suction and discharge device for the venom of the insect bites comprises a needle cylinder (1), a needle nozzle (2) below the needle cylinder (1) is connected with a butt joint pipe A (3), the butt joint pipe A (3) is connected with an air valve (4), the air valve (4) is connected with a connecting cover (6) through a butt joint pipe B (5), and a covering bowl (7) is connected below the connecting cover (6).
As shown in fig. 2, the air valve (4) is a one-way valve, and a valve port a (8) and a valve port B (9) of the one-way valve are connected with the butt joint pipe a (3) and the butt joint pipe B (5), and a flexible necking (10) is arranged inside the one-way valve.
The edge of the bowl cover (7) can be sleeved with a soft sealing ring.
The utility model discloses a theory of operation is:
as shown in FIG. 2, the two arrows are the directions of suction and deflation.
The bowl covering opening is aligned to the position damaged by the mosquito and the poisonous bee, the needle tube push rod is pulled, negative pressure is formed in the bowl covering opening, the skin of the affected part is sucked up, due to the single air valve, air cannot be automatically reversed, the bowl covering opening is kept for a period of time (the mosquito bites in 10 seconds generally, and bee stings can be properly prolonged), the piston is pushed downwards, the air is exhausted, the bowl covering opening is taken down from the position where the sting is wounded, and the bowl covering opening is stored for standby after being sterilized and cleaned.
The air is pumped up along with the push rod of the piston from the lower part, as shown by the arrow in figure 2, the air in the covering bowl is pumped out, the flexible necking in the air valve is closed, negative pressure is formed in the covering bowl, the covering bowl is tightly sucked at the bitten part, the venom is sucked out, when the air is exhausted, the piston of the needle cylinder is pushed down, as shown by the arrow in figure 2, the needle cylinder is arranged in the air valve cavity, the flexible necking crack of the air valve can be directly opened, the air is exhausted, and the covering bowl is easily taken down from the bitten part.
The bottom of the covered bowl is smooth and burr-free due to the fact that the bottom of the covered bowl is in contact with skin, and a soft sealing ring can be additionally arranged, so that air leakage at the hard part of a part of bones can be better avoided, and vacuum negative pressure can not be pumped.
The mosquito bite and expel experiment shows that the itching symptom can be eliminated immediately. The venom suction and discharge device is also an effective emergency treatment means for mild bee stings, gadflies, little bites (midges), poisonous snake bites and the like, which occur when bees and wasps sting in China, and after the simple manufacturing method of the venom suction and discharge device is popularized, the pain of the public is expected to be relieved.
During manufacturing, the piston can be manufactured into the simplest form, namely, a single air valve is not needed to be installed, the piston can be used only by the pumping negative pressure of the suction cylinder, and the piston is required to be kept tensioned by hands, so that the piston is inconvenient to use.
