Description
This utility model relates to a kind of magnetic orientation gastric mucosal cell harvester, and it belongs to technical field of medical instruments.
The gastric mucosal cell pathological diagnosis is to the very high scientific value of making a definite diagnosis of gastric cancer and other pathological changes of stomach.To the collection of gastric mucosal cell, adopt stomach pressure flush method, stomach friction, gastroscope direct-view brush cell, trace smear and tubule suction method down at present both at home and abroad.Above several method expense is higher, needs by means of X line or gastroscope equipment, and all can not comprehensive collection gastric mucosal cell, result's judgement needs the doctor to have more rich experience, in use brings very big misery to the person under inspection.
The purpose of this utility model is to overcome above-mentioned shortcoming, provide that a kind of reasonable in design, cost are lower, accurate positioning, patient's no pain, can the fresh gastric mucosal cell of comprehensive collection, the magnetic orientation gastric mucosal cell harvester that diagnostic result is accurate, safe and reliable.
In order to achieve the above object, this utility model now is illustrated by the following technical solutions in conjunction with the accompanying drawings.
Accompanying drawing 1 is a schematic diagram of the present utility model.
Accompanying drawing 2 is this utility model front views.
Accompanying drawing 3 is harvester structural representations.
Accompanying drawing 4 is collection head structural representations.
Accompanying drawing 5 is harvester tail structure sketch maps.
Accompanying drawing 6 is circuit diagrams of the present utility model.
As depicted in figs. 1 and 2, the utility model is mainly by gathering sensing instrument (2), collector (1) and permanent magnet form. Gather sensing instrument (2) and adopt its bag of charging accumulator (0.5 ampere-hour) Draw together housing and Circuits System, mainly by adjustable reference voltage source, amplifier, A/D conversion Device and digital display consist of. Permanent magnet is to be that raw material are made with neodymium iron boron, its shape Be cone, most advanced and sophisticated magnetic field intensity is 4000GS, effectively measures area and is not more than 0.1cm2, Penetration range is 15cm-60GS, 30cm-30GS, 45cm-10GS, can be according to penetration range And effectively measure requirement and adjustment magnet specification and size.
As shown in Figure 3, collector is by collection head (1), conduit (2), anti-drip valve (5), syringe needle (3), gas tube (4), input lead (7), ground wire (6) and output lead (8) form. Diameter is The conduit of 3mm (2) adopts medical plastic to make, and an end of conduit and collection head (1) link, Its other end and sensing instrument link, and are inserted with syringe needle (3), and the syringe needle tail end is equipped with gas tube (4), defeated people's lead (7), output lead (8) and three lines of steel wire (6) (ground wire) are provided with one Anti-drip valve (5), steel wire are 0.3mm2The specific arc stainless steel wire.
As shown in Figure 4, collection head (1) mainly is made up of Hall element (1,4) emulsion capsule (1,3), nylon wire (1,2) and gelatine capsule (1,1).Hall element is a kind of integrated circuit sensing element of being made up of preamplifier, Hall field generator and manostat, and it is connected with the other end of steel wire (6) with the collection joining input lead of sensing instrument (2) (7), output lead (8).Be provided with an air bag (1.3) outside this structure, it adopts medical latex to make, and is about 4cm, can hold 1000ml gas, and air bag is with thin nylon wire (1.2) outward, and it can be pulled down from harvester at any time to be equipped with an esophagus bolt (1.6) at air bag mouth place; With gelatine capsule (1.1) they all are encapsulated in the capsule, it is that diameter is the medical transparent capsule of 4.5mm.The harvester pipe range is 110cm.
When the person under inspection swallows conduit and harvester in the helmet, gelatine capsule dissolves after one minute, detect the collection head position with permanent magnet at its stomach wall, the magnetic signal of permanent magnet is in effective penetration range, Hall element that can sensitive inductive pick-up head, make it produce output voltage, this voltage forms linear change with permanent magnet magnetic field intensity size, the Hall voltage Vn of Hall element output, this signal voltage with ask poor from the reference signal Vr subtraction of adjustable reference voltage source, its difference △ Vs is amplified to required size through variable gain amplifier, sending A/D converter to be converted to numeral then shows, the peak-peak that shows magnetic axis on the display changes, and to determine the correspondence position of permanent magnet and collection head, determines the collection position of gastric mucosal cell at the projected position of body surface with permanent magnet.This moment in capsule injecting gas, air bag deployment, bladder shape changes with the different parts of place stomach, is enclosed within the outer thin nylon wire of air bag distending simultaneously, net capsule depended on pressure can effectively the rub comprehensive cell on the coat of the stomach, esophagus bolt and esophagus friction collection esophagus cell simultaneously; Take out gas in the most capsule then, harvester is taken out, pull down the esophagus bolt, each gets its cell respectively, accurately and effectively fresh cell pathology form is diagnosed.
This utility model can be used for the screening of gastric cancer and esophageal carcinoma, and the monitoring of the high-risk case of hospital and cytodiagnosis are to initiate advanced medical diagnosis apparatus both at home and abroad.
