In a second embodiment, the working principle of the pricking component 140 is specifically disclosed in this embodiment, please refer to fig. 3, in order to shield the needle 141 and prevent the patient with a dizzy needle from seeing the needle 141 when pricking, in this embodiment, a concave plate 121 is disposed on the collection side of the blood collection head 120, a needle insertion cavity 121A is formed on the collection side of the blood collection head 120 by the concave plate 121, the needle 141 is accommodated in the needle insertion cavity 121A, so that the whole pricking operation is completed in the needle insertion cavity 121A, the patient cannot see the needle 141, the needle 141 is slidably connected with the concave plate 121, then the needle 141 is telescopically moved in the needle insertion cavity 121A by the aid of the restoring component 142, specifically, an operation space is disposed on the periphery of the concave plate 121, as shown in fig. 4, the restoring component 142 includes a top plate 1422, the top plate 1422 is fixedly connected with the needle 141 in the operation space, the restoring component 142 further includes a support ring 1423, the support ring 3 is fixedly connected with the concave plate 121 in the operation space, a return spring 1421 is fixedly connected between the top plate 1422 and the supporting ring 1423, and when a needle is inserted, the pressure ends of the thumb stress plate 210 and the holding stress plate 220 contact the top plate 1422, and then the needle 141 is inserted into a finger by pressing the top plate 1422, and the needle 141 is not returned by the reaction force generated by the return spring 1421 after the needle is pressed, at this time, the finger slightly away from the needle 141 cannot be inserted into the needle 141 any more (that is, the finger needs to be slightly away from the needle 141 when blood is extracted).
It is worth noting that the collected blood enters the operation space through the needle inlet chamber 121A and then enters the blood storage chamber 110A.
In a third embodiment, the present embodiment improves the manner of collecting blood in the second embodiment to solve the problem that the blood is not smoothly introduced into the blood storage chamber 110A without a separate drainage structure, and is greatly influenced by external factors, so that the following improvements are made:
referring to fig. 3, an isolation seat 130 is disposed at a connection position of a blood storage tube 110 and a blood collection tip 120, a blood storage chamber 110A and an operation space are isolated by the isolation seat 130, a drainage assembly 150 is disposed at the periphery of a needle insertion assembly 140, the drainage assembly 150 includes two drainage seats 151 and two drainage tubes 152, the two drainage seats 151 are slidably connected with a concave plate 121, pressure ends of the two drainage seats 151 are mutually attached, a conical drainage structure is formed in a needle insertion chamber 121A after the attachment, referring to fig. 5, drainage grooves 1511 are disposed at sides of the two drainage seats 151 close to each other, so that when the conical drainage structure is formed, the drainage grooves 1511 of the two drainage seats 151 are attached to form a drainage port, when blood is collected from the blood storage tube 110 downward, as shown in fig. 7 and 8, blood dropped into the needle insertion chamber 121A flows along a conical surface of the drainage seats 151, and the drainage tube 152 is arranged at one side of the drainage seat 151 close to the isolation seat 130, one end of the drainage tube 152 passes through the isolation seat 130 to be communicated with the blood storage chamber 110A, and the other end is communicated with the drainage port, namely, the blood flowing on the conical surface enters the drainage port and then directly flows into the blood storage chamber 110A through the drainage tube 152, so that the process of flowing into the blood storage chamber 110A through the operation space is reduced, the problem of unsmooth flow caused by the influence of the reset piece 142 on the operation space is solved, and the sanitary condition of the reset piece 142 does not need to be considered after the direct drainage through the drainage tube 152.
In addition, the outside that lies in drainage groove 1511 on the syringe needle 141 conical plane is provided with water conservancy diversion piece 1512, and the surface of water conservancy diversion piece 1512 is to the lateral buckling at drainage groove 1511 place to play the effect of water conservancy diversion to blood, specifically form water conservancy diversion chamber 151A between two water conservancy diversion pieces 1512 after two drainage seats 151 laminates, the drainage mouth lies in water conservancy diversion chamber 151A, makes more effectual entering into of blood in the drainage mouth like this.
The working principle is as follows:
referring to fig. 7, after the finger is pricked, the pressure end is pulled outwards to separate from the top plate 1422, at this time, the top plate 1422 is reset by the force of the reset spring 1421, at this time, the needle 141 can be completely reset because the pressure end is separated, at this time, the finger does not need to be slightly away from the needle 141, the finger is not pressed by the blood sampling head 120 to make blood flow into the needle cavity 121A, before that, the separated pressure end is pushed inwards to make the pressure end contact the drainage seat 151, then the thumb stress plate 210 and the holding stress plate 220 are pressed during blood sampling, at this time, the pressure end acts on the drainage seat 151 to make the two drainage seats 151 joint, and the blood is drained into the blood storage chamber 110A to be stored by matching with the drainage port and the drainage tube 152.
A fourth embodiment, the holding of the thumb force-bearing plate 210 and the holding force-bearing plate 220 in the above three embodiments is not particularly limited, but the present embodiment improves the shielding plate set 230 in combination with the posture of holding the object by hand, please refer to fig. 9 and 10, the shielding plate set 230 includes a plurality of sealing shielding plates 231 and a plurality of visual shielding plates 232, the sealing shielding plates 231 and the visual shielding plates 232 are both disposed, the plurality of sealing shielding plates 231 are disposed on the top of the holding force-bearing plate 220 in a semicircular array, the plurality of visual shielding plates 232 are disposed on the top of the thumb force-bearing plate 210 in a semicircular array, because when the hand is holding, the thumb and the rest four fingers apply force separately, the thumb presses on the thumb force-bearing plate 210, the rest four fingers surround the holding force-bearing plate 220 and the sealing shielding plates 231, and the thumb tends to face the medical staff, and is not influenced by the rest fingers, and a visual space can be formed on the side of the thumb, therefore, for the convenience of observation, the side of the visual shielding plate 232 away from the thumb force-bearing plate 210 is inclined inward so that the medical staff can observe the blood collection condition at the bottom of the blood storage chamber 110A, and the four fingers cooperate with the sealing shielding plate 231 to block the side which can be seen by the patient, although the visual shielding plate 232 is inclined, the blocking of the sight can be still realized (the main purpose is to prevent other patients around from seeing).
Further, the sealing shielding plate 231 in contact with the holding force-bearing plate 220 is communicated with the air cavity 200A in the holding force-bearing plate 220, so that after the holding force-bearing plate 220 is pressed, air in the air cavity 200A is pressed into the sealing shielding plate 231 to expand, and then the blocking capability of the blood storage tube 110 is increased, the plurality of visual shielding plates 232 in contact with the holding force-bearing plate 220 are communicated with the air cavity 200A in the thumb force-bearing plate 210, and similarly, after the thumb force-bearing plate 210 is pressed, the visual shielding plates 232 expand to increase the blocking capability of the blood storage tube 110.
