In practical implementation, a controller with a timing function can be adopted, the timing function is started after the controller receives a signal of the pressure sensor 33, and the control cylinder is automatically started after a preset value is reached, so that the control cylinder extracts the hydraulic oil in the groove 31.
The specific implementation process is as follows:
before the blood sampling, earlier the manual work place equipment on the sick bed to with the elasticity piece 11 card on vertical railing, carry on spacingly to base 1, then rotate the connecting seat, make montant 3 remove around blood sampling department, and make the center department of clamp plate 7 towards blood sampling department. And stick outer cylinder 9, inner tube 8 and clamp plate 7 mutually, pass spacing hole 63 and the through-hole of aliging with connecting rod 93, then start the control cylinder, let in hydraulic oil in the clamping cylinder 5 in to recess 31, make first splint 6, third splint 62 slide right, second splint 61 slide left, make the dislocation takes place for three spacing hole 63 of aliging, close the control cylinder after carrying out preliminary positioning to connecting rod 93, first pressure is pressed the piece 83 towards blood sampling department this moment.
When blood sampling is finished and the blood sampling position needs to be pressed, the control cylinder is started, hydraulic oil is introduced into the groove 31 and the clamping cylinder 5 through the control cylinder, the push rod 41 is enabled to slide downwards, the pressing plate 7 is driven to slide downwards, and the first pressing block 83 is pressed on the blood sampling position. As the amount of hydraulic oil entering the groove 31 increases, the pressure between the first pressing block 83 and the blood collection site increases, and the greater the deformation of the first pressing block 83, the first piston 81 is pushed upward, so that the first piston 81 is fixed to the pressure plate 7 via the adhesive layer 82. Meanwhile, the greater the pressure in the groove 31 is, the slider is pushed to the right, the pressing spring 34 is pressed on the pressure sensor 33, and when the pressure detected by the pressure sensor 33 is greater than the preset value related to the pressure in the controller, the control cylinder is closed, and the continuous pressing is stopped.
When the pressing time is up, the control cylinder is started again, the hydraulic oil in the groove 31 and the clamping cylinder 5 is pumped out, the push rod 41, the first clamping plate 6, the second clamping plate 61 and the third clamping plate 62 are reset, and the connecting rod 93 is loosened. The push rod 41 drives the limiting plate 4, the first clamping plate 6, the second clamping plate 61, the third clamping plate 62 and the pressing plate 7 to move upwards, the pressing plate 7 drives the first piston 81 to move upwards synchronously, and the outer cylinder 9 and the inner cylinder 8 are not pressed downwards any more by the pressing plate 7 at the moment, so that when the first piston 81 slides upwards, the outer cylinder 9 and the inner cylinder 8 are driven to slide upwards. Since the sliding spring 36 is disposed above the connecting rod 93, the connecting rod 93 cannot move upward due to the action of the sliding spring 36, and therefore, the first piston 81 slides upward relative to the second piston 92, the first pressing block 83 releases the blood collection site, and the second pressing block 91 slides downward relative to the outer cylinder 9.
If blood sampling department still does not coagulate blood, first according to the back that the piece 83 relaxs, blood still can be followed blood sampling department and flowed out, get into the second and press in the piece 91, make the second press the humidity increase in the piece 91, and the second is pressed the humidity change in the piece 91 and can be detected out by humidity transducer, after humidity increase, humidity transducer can send the signal of telecommunication to the controller, make control cylinder start, let in hydraulic oil in recess 31 and the centre gripping cylinder 5 once more, make catch bar 41 slide downwards once more, drive first splint 6, second splint 61 and third splint 62 and slide downwards. And after lubricating oil got into in the centre gripping cylinder 5, first splint 6, second splint 61 and third splint 62 centre gripping connecting rod 93 once more, so first splint 6, second splint 61 and third splint 62 slide down can drive second piston 92 and slide down, press the second to press the briquetting 91 downwards, impel the second to press briquetting 91 to take place to deform, and the second is pressed briquetting 91 and is slided out urceolus 9 downwards this moment, so the second is pressed briquetting 91 and can take place the increase of the degree of deformation, the second is pressed briquetting 91 and is out of shape after, and the second is pressed briquetting 91 increases, and the contact surface between patient's skin increases, can press blood sampling department automatically, avoid leading to the patient that the blood coagulation function descends still can't the blood coagulation after pressing because of diseases such as hypertension or under the medicine effect that uses, lead to a large amount of blood outflow.
When the equipment of in-service use has the timing function, reach the time of predetermineeing the back, the controller can open the control cylinder automatically, and need not medical staff's manual work and judge the time, further reduces medical staff's work load.
The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
