On this basis, further: sucker under the knob of the center of circle, can be provided with.The addition of sucker, makes ten million will not move easily on paper with ruler for learning, improves stability during use.
On the basis of above-mentioned any embodiment, further: one end of vernier 5 can be provided with breach.Arranging of breach in the position making the fixing nib of bowlder, can make nib and ten million keep relative position constant with ruler for learning, improve the stability making bowlder, improve Consumer's Experience.
On the basis of above-mentioned any embodiment, further: cylinder 10 can be provided with magnifier.The setting of magnifier, facilitates user to see the scale on cylinder clearly, improves Consumer's Experience.
On the basis of above-mentioned any embodiment, further: described ruler for learning is plastics or metal material.The benefit of plastic material is, lightweight, technique is simple, cost is low;The benefit of metal material is, texture is more preferably.
On the basis of above-mentioned any embodiment, further: described circular hole 7 is preferably located at the two ends, left and right of ruler for learning.Circular hole 7 is positioned at the two ends, left and right of ruler for learning, it is simple to user draws circle.
On the basis of above-mentioned any embodiment, further: described painting black holes 6 is preferably located at the two ends, left and right of ruler for learning.It is coated with black holes 6 and is positioned at the two ends, left and right of ruler for learning, it is simple to user's blacking answering card.
As shown in Figures 2 and 3, on the basis of above-mentioned any embodiment, further: one end of cylinder 10 can be provided with dismountable blood of human body harvester 12;Blood of human body harvester 12 includes particle emission device, particle emission device includes launching chamber, the slip of emission cavity indoor is provided with transmitting piston 31, transmitting chamber is launched piston and is divided into the first chamber 32 and the second chamber 33, transmitting piston 31 is the first end face towards the end face in the first chamber 32, transmitting piston 31 is the second end face towards the end face in the second chamber 33, second end face is fixedly connected with transmitting bar 34, it is consistent with launching the piston 31 glide direction in emission cavity indoor to launch bar 34, it is detachably mounted with gas generating unit 24 in first chamber 32, the steam vent 16 producing gas for discharging gas generating unit 24 it is provided with in the first chamber 32, first chamber 32 connects with transmitting tube 35, launch bar 34 and be slidably arranged in transmitting tube 35, the inherent front side launching bar 34 of transmitting tube 35 is additionally provided with transmitting granule 17;Second chamber 33 is additionally provided with for launching the back-moving spring 18 that piston 31 resets;Second chamber 33 also connects with the airway 26 of storage blood module, storage blood module includes airway 26 and storage haemocoele 19, storage haemocoele 19 is provided with and realizes launching the transmitting through hole 20 that granule 17 runs through, transmitting through hole 20 is distributed along the Way out of transmitting tube 35, and storage blood module is detachably connected with particle emission device;Storage haemocoele 19 sidewall is additionally provided with blood delivery outlet 23, for being tightly connected the blood gathered is shifted and detected with blood testing equipment;Being additionally provided with in second chamber 33 for reducing the cushion hole 21 launching recoil time granule 17 is launched, cushion hole 21 is arranged on the sidewall in the second chamber 33, and along launching the reverse oblique outer setting of piston 31 transmitting granule 17;Be additionally provided with the connectivity part of storage haemocoele 19 in second chamber 33 can only to the second chamber 33 unidirectional the first check valve 22 opened;Blood delivery outlet 23 is additionally provided with can only to internal unidirectional the second check valve opened of storage haemocoele 19.
Along with popularizing of domestic medical device, being much provided with hemanalysis instrument in other, blood of human body harvester 12 gathers blood of human body, and the blood of collection is sent to hemanalysis instrument.Hemanalysis instrument includes electrochemica biological sensor and processor, and electrochemica biological sensor can include one or more in reflectance spectrum biosensor, vitamin biosensor, Cholesterol Biosensor, glucose biological sensor, semi-differential volt-ampere type leukocyte-biological sensor;Processor is for receiving the data of electrochemica biological sensor collection and processing.Being incorporated as of blood of human body harvester 12 necessarily adds, with ruler for learning, the function gathering blood so that it is function is no longer single;Launching granule 17 in use procedure and can adopt ice pellets, its blood collection procedure is painless, and amount of bleeding is little, harmless, environmentally safe, meets the demand of health detection to a certain extent.
By arranging cushion hole 21 on the second chamber 33, it is possible to avoid launching the recoil that is subject to of chamber excessive, and cause that moment expands the distance between blood of human body harvester and human body, it is to avoid blood cannot be flowed into the problem in storage haemocoele.
When gas generating unit is in time producing gas in the way of blast, the instantaneous pressure produced can significantly more than the gas pressure in the second chamber 33, the first check valve 22 it is enough to be promoted transmitting granule 17 to inject in human body by the motive force in the first chamber 32 so launching piston 31, so now may be at closed mode;And in the process launching piston 31 return, in the second chamber 33, produce negative pressure, it is possible to by storing up haemocoele 19, blood is sucked.The setting of the first check valve 22, it is prevented that launch motive force when granule 17 is launched because weakening with storing up connecting of haemocoele 19 in the second chamber 33.
In the process launching piston 31 return, easily directly blood is sucked when launching through hole 20 air inlet, arranging on blood delivery outlet 23 can only to internal unidirectional the second check valve opened of storage haemocoele 19, storage haemocoele 19 just can fill into air from the external world, avoid negative pressure excessive in the second chamber 33 to be drawn into by blood in the second chamber 33, and cause in the second chamber 33 and be contaminated.
On this basis, further: between storage haemocoele 19 and airway 26, absorbed layer 25 can be provided with.The setting of absorbed layer 25, it is prevented that blood enters airway 26, keeps the cleaning of airway so that it is can recycle.
The material storing up haemocoele in blood of human body harvester is not limited by the embodiment of the present invention, preferably, storage haemocoele 19 can adopt transparent material, make user can be visually observed that the use state of storage haemocoele 19, it is easy to timely replacing, improve the safety of blood of human body harvester, ensure user health.
Although present invention has been a degree of description, it will be apparent that, without departing from the spirit and scope of the present invention when, can carry out the suitable change of each condition.Being appreciated that and the invention is not restricted to described embodiment, and be attributed to scope of the claims, it includes the equivalent replacement of described each factor.
