Background
The eyes are windows of soul, are important organs of human bodies and are important ways for receiving external information, but the eyes are also relatively fragile organs, and compared with hands and feet and internal organs with body protection, the eyes are exposed in the external air and are threatened by external invasion all the time.
Therefore, eye diseases are also one of the high-incidence diseases, the conjunctival sac needs to be cleaned and disinfected before the eye operation, the conjunctival sac needs to be cleaned by normal saline before the eye operation, povidone is needed to be used for comprehensively disinfecting the conjunctival sac before the operation is started, the cleaning in the first step or the povidone disinfection in the second step is needed, all-around dead-angle-free operation is needed, and otherwise, the bacteria in the conjunctival sac can cause postoperative infection.
Conjunctivitis is a common eye disease, and is a high incidence of conjunctivitis because most people have bacteria in their conjunctival sac and proper temperature and humidity, and most conjunctival surfaces are directly contacted with the outside and are easily attacked by various external stimuli and microorganisms. The important scheme for treating conjunctivitis is to wash conjunctival sac endocrine substances by using normal saline and boric acid water. Or selecting highly targeted and sensitive drugs, 0.1% iodoglycoside, 0.05% cyclocytidine and the like to clean eyes.
However, the existing eye washing device and the existing needle head washing device can not accurately wash the conjunctival sac part, so that on one hand, cross infection of other parts of the eye is easily caused, and on the other hand, the patient feels more discomfort due to the waste of medicines.
SUMMERY OF THE UTILITY MODEL
The utility model provides a needle head for thoroughly washing and disinfecting a conjunctival sac, aiming at the technical problems that the pertinence is not strong when the needle head and an eye washer are used for washing the conjunctival sac, other parts in the eye are easy to infect, medicine is wasted, and discomfort of a patient is aggravated.
In order to achieve the purpose, the utility model provides the following technical scheme:
the needle head for thoroughly washing and disinfecting the conjunctival sac comprises a liquid channel, wherein a fan-shaped part is arranged at the front end of the liquid channel.
In the utility model, a plurality of groups of needle cavity channels are arranged in the fan-shaped part.
In the utility model, the periphery of the fan-shaped part is arc-shaped.
In the utility model, one end of the liquid channel far away from the fan-shaped part is provided with a needle tail part.
In the utility model, the inner cavity of the needle tail part is in a circular truncated cone shape, and the section of the inner cavity is in an oval shape.
In the present invention, the thickness of the sector is the same as the diameter of the liquid passage.
In the utility model, the diameter of the end of the needle cavity close to the liquid channel is small, and the diameter of the end of the needle cavity far away from the liquid channel is large.
The utility model has the following beneficial effects:
according to the needle head for thoroughly washing and disinfecting the conjunctival sac, the adaptability to the conjunctival sac is enhanced by using the fan-shaped needle head, the disinfection and washing effects of the conjunctival sac are improved, the risk of injury to a patient caused by the acupuncturing needle head is reduced, the needle head can be well combined with a traditional needle tube, the use is convenient, the cost of installing equipment such as an eye washer is reduced, the injury to the eye is small, the discomfort is reduced, and the needle head has wide applicability in the field of eye disease treatment.
