Description

Nasal cavity spraying type shower nozzle

Technical Field

The utility model belongs to the technical field of medical treatment and family nursing apparatus, concretely relates to nasal cavity spraying type shower nozzle.

Background

Nasal mucosa administration is considered as an administration mode in which a medicament can be quickly and efficiently absorbed, and a plurality of fine villi are arranged on nasal mucosa cells, so that the effective absorption area of the medicament can be greatly increased; the medicine can directly enter the systemic circulation after being absorbed by the mucosa.

The nasal spray device is used as an essential tool for nasal mucosa administration, and the atomization effect and the use comfort of the nasal spray device are very important. The nasal spray device is generally composed of a dust cap, a spray head and a tank body, and the atomization effect and the use comfort of the nasal spray device are mainly closely related to the design of the spray head of a product.

Chinese patent CN 201807034U discloses a novel nasal cavity spray nozzle, which is convenient to disassemble by designing the inside of the nozzle main body into a cavity structure and separately designing the spray rod and the connecting rod into a tubular shape. However, the design of the spray head easily causes the assembly difficulty to be larger, the sealing performance to be poorer and the occurrence rate of liquid leakage phenomenon to be higher. The spray rod is designed into a tubular shape, so that the solution is directly sprayed out, and the atomization effect is poor; the atomization effect of the product can be increased to a certain extent by increasing the pressure in the tank, but the solution has larger impact force on the nasal mucosa due to overlarge pressure, so that the symptoms of nasal cavity stimulation, nasal cavity mucosa bleeding and the like are caused.

Chinese patent CN 203107638U discloses a nasal cavity spray head, which is designed into a gourd shape or an olive shape so as to be suitable for different people, can be comfortably clamped in the nasal cavity vestibule and is not easy to fall off; the top end surface or the periphery of the top end of the spray head part is provided with a plurality of liquid outlet holes, so that the water outlet pressure of the nasal cavity spray head can be widely suitable for different people. The patent improves the use comfort and the atomization effect of the product to a certain extent, and only changes the top end surface or the periphery of the top end of the spray head part are limited, and the design of the interior of the spray rod is mentioned.

Through trying out, analyzing to the shower nozzle that above-mentioned patent and domestic market were sold on the market, mainly summarize following defect: 1) the spray rod of the spray head is mostly in a tubular design, and the sprayed solution cannot be fully atomized; 2) the spray rod and the connecting rod are processed separately, so that the assembly difficulty is high, and if the assembly part is not sealed well, the liquid leakage phenomenon is easy to occur; 3) the shower nozzle is pressed the position and is mostly glossy platform design and pressing surface narrower, and is inconvenient to press, and the liquid that spills over when using easily causes the smooth phenomenon of hand.

Disclosure of Invention

The utility model aims at overcoming the defects of complex structure and larger assembly difficulty of the existing nasal cavity spray type spray head.

Therefore, the utility model provides a nasal cavity spray type spray head, which comprises a spray head main body, wherein the spray head main body is in a shape of a cone inclined on one side, a spray head part is arranged at the top end of the spray head main body, a connecting part is integrally arranged at the bottom end of the spray head main body, and a spray pipe is arranged in the spray head main body; the top of the spray head part is provided with a liquid spraying hole, the spray pipe is connected with the interior of the spray head part, and the top end of the spray pipe is arranged corresponding to the liquid spraying hole; the sprayer body is close to the sprayer head part and is sleeved with a convex part; the surface of the convex part connected with the spray head part is provided with a step.
