Description
[technical field]
This utility model relates to and is used for the laser medical equipment technical field, relates in particular to a kind of laser hemostix of laser inspection equipment.
[background technology]
Along with the continuous development of laser technology, laser in the application of medical field more and more widely, laser detection equipment has also obtained application in clinical.
All the time, doctor and patient are all being tormented in the tip blood sampling, all bring many miseries for doctor and patient.Existing tip blood collecting technology commonly used has nib blood taking needle and bayonet type blood taking needle.Disposable nib type blood taking needle commonly used is very easily worn out plastics package and is polluted, and the time have the situation of stabbing the staff to take place, and how this material of disposable nib blood taking needle to sterilize, shelf-life length also is difficult to can tell.This kind blood taking needle pin edge is whole, and rough surface is very easily torn skin and keenly felt strong.Because needle body exposes, patient's psychentonia is difficult to accept.
The position of tip blood sampling is a finger, keenly feels more so, and many patients refuse corresponding the inspection because of being afraid of pain.Depth of needle is difficult to grasp the bad control of amount of bleeding.Skin is thicker too shallowly to be had to prick for the second time because of thrusting, and causes the patient suffering, has increased workload simultaneously.Because inserting needle is too shallow, the excessive compression of having to is sometimes sneaked into tissue fluid, easily causes the change of blood coagulation and blood constituent.
For bayonet type blood taking needle (bushing type), this kind is provided with small and exquisite simple, domesticly still seldom uses.Whole device separated into two parts, a part are the lancets that has disposable shaping pressure handle, and another one is the sleeve pipe of lancet, and the inwall of pipe has the bayonet socket design.During blood sampling pin is put into sleeve pipe, the sleeve pipe end opening is pressed on the skin, firmly the pressing handle.Pin is crossed bayonet socket and is thrust skin fast.Major advantage is a good concealment, and the design of pin also has improvement, but the patient still has very strong pain.
Therefore, in order to change shortcoming such as blood sampling instrument etc., we have designed a kind of novel laser hemostix, to overcome above-mentioned shortcoming.
[utility model content]
The purpose of this utility model is exactly the laser hemostix of a kind of tip blood sampling method of inspection that provides in order to solve the imperfect of prior art.
This utility model provides a kind of laser hemostix, comprise: cabinet, the laser instrument that cooperates with cabinet, also comprise cylindrical mirror on the path that is positioned at the laser instrument outgoing laser beam, convex lens and removable protective cover, wherein, described protective cover be positioned at laser output near.
Wherein, described laser instrument, cylindrical mirror and convex lens are fixed in the annular seal space, and described laser output is positioned at the bottom in sealing chamber.
Wherein, the built-in moistureproof moisture absorption apparatus of described annular seal space is as desiccant, dry gas and noble gas etc.
Wherein, be provided with parallel placement laser crystal and xenon flash lamp in the described laser instrument, xenon lamp the two poles of the earth are respectively from the extraction electrode wiring of two ends up and down of annular seal space.
Wherein, described annular seal space is fixed in the cabinet.
Wherein, described annular seal space is connected with cabinet by the electrode connection of drawing.
Wherein, further comprise with this laser hemostix and carry out interactive operation interface.
Wherein, further comprise with this laser hemostix and carry out interactive foot controller.
Wherein, described laser instrument is a solid state laser.
This utility model is taken a blood sample by laser, because the suitable operation wavelength of the employing of this laser instrument is between 1900nm-2940nm, the laser of this wavelength period overlaps with the absworption peak of water, and be moisture more than 70% in the tissue, the laser of this wavelength period is very easily absorbed by hydrone, can obtain bigger action effect with less energy, this superiority be other wavelength can't be obtained.Because the laser of this wavelength period has the special biological effect that can not make blood coagulation, laser itself has the high energy bacteriostasis simultaneously, thereby to replace traditional blood taking needle with the laser of this wavelength period be that patient carries out contactless blood sampling, avoid cross infection, can avoid infection fully HIV or hepatitis B virus, and mechanical damage and hot injury to human body are smaller, no pain, and wound healing is fast.This laser hemostix has design outward appearance novelty, compact conformation, simple to operate, characteristics such as safety coefficient is high, the no pain of treatment.This novel practical can be widely used in the tip blood sampling of all kinds of hospitals.
