Abstract
The utility model discloses a device for wearing and taking out a child contact lens. The device comprises a round sucker, a connecting pipe and a negative pressure airbag, wherein the round sucker is communicated with the negative pressure airbag through the connecting pipe; an exhaust hole is formed in an abutted surface of the round sucker and the connecting pipe; and the round sucker, the connecting pipe and the negative pressure airbag are made of soft rubber layers. A closed space formed by the connecting pipe and the negative pressure airbag is adjusted to generate a negative pressure by extruding or releasing the negative pressure airbag, so that the contact lens is firmly sucked or placed at a proper position through the round sucker. The device is safe and can be used for conveniently and quickly wearing and taking out the contact lens, so the device is particularly suitable for children.
Description
Technical field:
This utility model relates to the field of tool of wearing contact lens, is specifically related to a kind of child's contact lens and wears and extractor.
Background technology:
At present; Because contact lens has advantages such as good, the attractive in appearance and convenient use of visual quality, contact lens has good effect to the anisometropia of correcting the big number of degrees simultaneously, and the patient is acceptant; Therefore the correction of refractive errors that is fit to very much congenital cataract infant postoperative aphakic eye; The correction of refractive errors effect of simple eye aphakic eye particularly, contact lens wear a series of complication that can avoid too early implantable artificial crystalline lens to bring, so it more and more receives international pediatric ophthalmology expert's approval.
Yet, no matter be for adult or child, wearing and taking out of contact lens all is not to be easy to thing, needs to be grasped certain skill.Comparatively the method for approval was the operation that the wearer uses the finger of oneself to wear and take out in the past, and user need pass through good training and could correctly use, and existence is infected and the risk of eyeball damage.The free-hand method of wearing contact lens of adult can't be promoted in child's user.Because the most conformabilities of child are poor, the child wears contact lens majority under waking state to be needed to adopt hardball, or can only be chosen in sleep soundly or anaesthetize under use, so need fast and safely wear removing method and suitable practical tool.
At present, still there is not the same instrument can satisfy the function of fast and safely wearing and taking out contact lens for the child on the market.
The utility model content:
The purpose of this utility model provides a kind of contact lens and wears and extractor, especially is convenient to child's quick donning and takes out contact lens, not only safety and fast convenient.
This utility model is achieved through following technical scheme: contact lens is worn and extractor, comprises circular magnetic chuck, connection tube; Negative pressure gasbag, said circular magnetic chuck is connected with negative pressure gasbag through connection tube, and said circular magnetic chuck and connection tube abutted surface place have steam vent; Said circular magnetic chuck; Connection tube, negative pressure gasbag constitutes by the soft rubber layer.
Said circular magnetic chuck is connected with negative pressure gasbag through connection tube; Circular magnetic chuck and the negative pressure gasbag connection tube of being separated by; So do not need directly to contact with contact lens; Just can accomplish wearing and the taking-up task of contact lens fast, avoid current needs directly to use finger to operate the secondary infection problem that possibly cause.
Only need negative pressure gasbag is pushed or loosens the negative-pressure adsorption power of scalable circular magnetic chuck during operation; Wear the infant that contact lens carries out correction of refractive errors or special examined needs for needs; This instrument can be infant quick donning, adjustment and taking-up contact lens; And do not need other special instrument to assist, not only convenient and practical but also quite safe.
Adopt soft rubber as raw material production, with low cost, use repeatedly after product not only can be sterilized, and also be suitable in the operation behind this instrument sterilization or post-operative wound uses when not healing.
The contact lens of this utility model is worn with extractor and is passed through the extruding negative pressure gasbag; The confined space that makes connection tube and negative pressure gasbag form produces enough big negative pressure; Thereby contact lens is held firmly through circular magnetic chuck; Not only safety and make things convenient for quick donning and take out contact lens especially is fit to the child and uses.
R&D process of this utility model and patent application process expense receive Ministry of Public Health subordinate (pipe) 2010-2012 of hospital year clinical speciality key project " congenital cataract operation opportunity and art formula are to the influence of late result " (project sequence number: 175) subsidize.

Fig. 3 is the sketch map of the cooperating of this utility model and contact lens;
Fig. 4 is the sketch map of the cooperating of this utility model and contact lens;
Wherein, 1, circular magnetic chuck; 2, connection tube; 3, negative pressure gasbag; 11, steam vent.
The specific embodiment:
Below be to the further specifying of this utility model, rather than to the restriction of this utility model.
Embodiment 1:
As shown in Figure 1, the specific embodiment one of this utility model: contact lens is worn and extractor, comprises circular magnetic chuck 1; Connection tube 2, negative pressure gasbag 3, circular magnetic chuck 1 is connected with negative pressure gasbag 3 through connection tube 2; Circular magnetic chuck 1 has steam vent 11, circular magnetic chuck 1, connection tube 2 with connection tube 2 abutted surface places; Negative pressure gasbag 3 constitutes by the soft rubber layer.
Like Fig. 2,3, shown in 4, dotted portion is a contact lens, and contact lens is worn with the work process of extractor following:
1. push negative pressure gasbag 3, air is extruded, negative pressure gasbag 3 is flattened;
2. circular magnetic chuck 1 is pasted and pay, and circular magnetic chuck 1 is closely pasted with minute surface mutually, circular magnetic chuck 1 intermediary steam vent 11 is sealed by the contact lens outer surface at the contact lens outer surface;
3. because connection tube 2 has formed confined space with negative pressure gasbag 3, after relieving negative pressure gasbag 3 opened negative pressure gasbag 3 again, this confined space had produced certain negative pressure;
4. the negative pressure that produces of negative pressure gasbag 3 can hold contact lens through circular magnetic chuck 1 firmly;
5. this moment, can contact lens be taken off (or from the glasses film magazine, taking out) from the eyes anterior corneal surface;
The contact lens plate inner surface that 6. will be adsorbed on the circular magnetic chuck 1 is aimed at eyes anterior corneal surfaces (or in lens receiver);
7. push negative pressure gasbag 3, the pressure of confined space is increased, the negative pressure of circular magnetic chuck 1 is removed, and contact lens is thrown off from circular magnetic chuck 1;
8. contact lens inner face and anterior corneal surface form negative pressure and firmly are worn to cornea surface (or directly putting back in the lens receiver).
Claims (1)
