Description

Technical Field

[0001] The utility model belongs to the technical field of spray bottles, and in particular relates to a flat-mouth paste pumping and spraying device. Background Art

[0002] In the first aid of patients with cardiac arrest, a defibrillator is often used to pass a strong pulse current through the heart to eliminate arrhythmias and restore sinus rhythm. The electrode pads of the defibrillator need to be coated with conductive paste in front of the electrodes to reduce the patient's body impedance, avoid unnecessary damage, and make the electrode pads in close contact with the patient's skin to improve the defibrillation effect. Currently: medical staff manually operate, after applying "Z"-shaped conductive paste on the two electrode pads respectively, fit the two electrode pads together and rotate and rub them so that the conductive paste is more evenly distributed on the electrode pads or directly apply the conductive paste to the patient's body at the defibrillation site, and then place the electrode pads for defibrillation. However, these traditional application methods are time-consuming and labor-intensive, and even often cause unnecessary skin burns due to uneven application.

[0003] In addition, the toothpaste-like conductive paste and bottled conductive paste commonly found on the market tend to coagulate after being left for a long time. After coagulation, it is slow to pour out from the bottle mouth. In the moment of rescue when every second counts, the bottle mouth must be squeezed hard to squeeze the conductive paste out of the bottle, which is more likely to affect the rescue time.

[0004] Therefore, a coating device that facilitates quick pumping out of the conductive paste and more evenly applies it can save time and improve rescue efficiency. Utility Model Content

[0033] Example 1

[0034] The present embodiment discloses a flat-mouth paste pumping and spraying device, comprising a bottle body 1 and a bottle cap 2, wherein the bottle body 1 and the bottle cap 2 are detachably connected.

[0035] The bottle cap 2 is provided with a pumping assembly 3 and a flat nozzle 4. The pumping assembly 3 pumps out the paste in the bottle body 1 and sprays it evenly through the flat nozzle 4.

[0036] The flat nozzle 4 has a liquid inlet 41 at its end and a liquid outlet 42 at its front end. The liquid outlet 42 is flat in design, with a height smaller than that of the liquid inlet 41 and a width larger than that of the liquid inlet 41 .

[0037] The liquid inlet 41 adopts a circular structure. A flat cavity 43 is provided near the liquid inlet 41 of the flat nozzle 4. The width of the flat cavity 43 gradually increases toward the liquid outlet 42.

[0038] A plurality of guide grooves 44 are disposed in the flat cavity 43 . The guide grooves 44 extend to the liquid outlet 42 , and a plurality of liquid outlet holes 45 are formed at the position of the liquid outlet 42 .

[0039] The pump assembly 3 includes a liquid suction pipe 31 , a pump-out pipe 32 , a three-way pipe 33 , a piston chamber 34 , a piston 35 and a handle 36 . The liquid suction pipe 31 , the pump-out pipe 32 and the piston chamber 34 are respectively connected to the three joints of the three-way pipe 33 .

[0040] The piston 35 is disposed in the piston chamber 34 . A push rod 351 and a return spring 352 are disposed at the bottom of the piston 35 . The end of the push rod 351 is hinged to the handle 36 .

[0041] A locking assembly 37 is provided on the upper portion of the pipette 31 . The locking assembly 37 includes a second spring 371 and a ball 372 . The ball 372 blocks the pipette 31 under the action of the second spring 371 .

[0042] The flat nozzle 4 is made of soft silicone material. The bottle body 1 and the bottle cap 2 are made of hard plastic.

[0043] When the handle 36 is pulled outward, the piston 35 moves outward, and the gas at the liquid outlet 42 flows rapidly into the three-way pipe 33. Due to the Bernoulli principle, the fluid flows rapidly, causing the surrounding air pressure to decrease. At this time, the air pressure in the bottle body 1 is greater than that in the three-way pipe 33. The conductive paste in the bottle body 1 pushes the ball 372 away and flows from the high-pressure bottle into the low-pressure three-way pipe 33 through the pipette 31. When the handle 36 is pressed inward, the piston 35 compresses the air pressure in the three-way pipe 33. At this time, the second spring 371 presses the ball 372 to ensure the sealing of the pipette 31. The conductive paste in the three-way pipe 33 will not flow back into the bottle body 1, but will flow to the outside through the flat cavity 4.

[0044] The specific embodiments of the present invention are described in detail above, but they are only examples, and the present invention is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modification and substitution of the present invention is also within the scope of the present invention. Therefore, the equivalent transformation and modification made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
