Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a clamping device and a rotor structure using the clamping device. Background Art

[0002] In the pre-treatment of blood gas analysis in clinical testing work, it is necessary to shake the syringe after collection. The existing technology mostly adopts manual mixing, which has some potential disadvantages, mainly including: Safety risks of medical personnel: In the process of transporting, receiving and mixing blood gas specimens with needles, medical personnel are at risk of being pricked by needles. Inconsistency of mixing operation: Different inspectors, or even the same inspector, may mix specimens at different times and to different degrees, which may lead to analytical errors in blood gas test results. Difficulties in handling when the workload is large: When the workload is large, manual mixing of blood gas specimens is time-consuming and laborious, and inspectors may not be able to process all blood gas specimens in time, and cannot meet the requirements of blood gas analysis on a first-come, first-served basis, which may affect the timeliness and accuracy of the test.

[0003] In the prior art, refer to the Chinese utility model patent with authorization announcement number CN206762786U, which discloses a blood gas specimen mixer, which specifically discloses a fixed barrel of a syringe in the blood gas specimen mixer, a plurality of clamping sections extending from the top of the inner cavity of the fixed barrel, the clamping sections can produce deformation in a direction away from the axis of the fixed barrel, a protrusion is provided on the inner side of the end of the clamping section, the diameter of the cylindrical space between the proximal surfaces of the plurality of protrusions is smaller than the diameter of the syringe barrel, a plurality of notches are provided on the outer wall of the fixed barrel, the syringe can be inserted into the fixed barrel, the plurality of clamping sections on the fixed barrel allow the syringe to be inserted through deformation, and the syringe is limited and fixed by the plurality of protrusions on the clamping sections. However, the fixed barrel has certain technical defects: 1. The fixed barrel can only accommodate and pass through syringes or needles of the same size as the opening of the clamping section. In actual clinical operations, there are many needles with diameters much larger than the syringe barrel, and some needles are of special shapes. The clamping section and protrusion design in this patent make it impossible for many syringe needles to be inserted into the fixed barrel, or the needle can be inserted but the opening of the clamping section is too large to clamp the syringe barrel. It has too high requirements on the size and model of the syringe and the needle, and cannot meet the complex and diverse clinical operation needs; 2. The structure of the fixed barrel can only realize one-way fixed limit insertion of the syringe, which is very inconvenient to remove the syringe from the fixed barrel after mixing.

[0004] Therefore, it is necessary to design a clamping device for clamping the syringe to increase the stability of the syringe being clamped during the mixing process of the syringe in the early stage of blood gas analysis, increase the diversity of needle specifications and syringe specifications that the clamping device can adapt to, and improve the convenience of removing the syringe from the clamping device, thereby greatly reducing the possibility of occupational exposure faced by medical staff in blood gas testing, improving the operational efficiency of the preliminary preparation for blood gas analysis, and reducing the workload of medical staff.

Detailed Embodiments

[0020] To make the purpose, principle and structure of the present utility model clearer, the following further elaborates with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment 1:

[0022] Referring to Figure 1-3 , this embodiment provides a clamping device, the middle of the clamping device bulges, and the top of one end is narrowed. The specific clamping device includes: a clamping head 1, a hollow structure 3 and a hollow channel 4.

[0023] A through hole 6 is provided in the middle of the clamping head 1, a number of grooves 2 are provided in the circumferential direction of the clamping head 1, and a number of convex clamping parts 5 are also provided on the inner side of the top of the clamping head 1.

[0024] The hollow structure 3 is arranged in the middle of the clamping device, and the hollow structure 3 can allow the head of the syringe and the syringe needle to pass through.

[0025] The hollow channel 4 penetrates through the clamping device from the hollow structure 3 to the top of the clamping head 1. The hollow channel 4 cooperates with the groove 2 of the clamping head 1, so that the clamping head 1 and the hollow channel 4 can be deformed to allow the body of the syringe to pass through.

[0026] When the syringe needs to be installed, the syringe head and the needle are sent into the hollow structure 3. Then the syringe body is pressed, so that the syringe body squeezes the hollow channel 4. The hollow channel 4, the plurality of grooves 2 and the clamping head 1 are deformed under the action of the extrusion force. The deformation makes the gap of the hollow channel 4 larger to allow the syringe body to pass through. After the syringe body passes through the hollow channel 4, it enters the inner cavity of the clamping device. At the same time, the syringe head and the needle also enter the inner cavity of the clamping device through the hollow structure 3. At this point, the syringe as a whole enters the inner cavity of the clamping device. In addition, a plurality of protruding clamping parts 5 are also provided on the inner side of the clamping head 1. When the syringe is in the clamping device, the clamping part 5 of the clamping head 1 is pressed against the syringe body. At this time, the clamping head 1 is slightly deformed due to the entry of the syringe body. The material deformation brings preload force, which is transmitted to the syringe body through the clamping part 5, so that the syringe can be stably clamped in the clamping device.

[0027] When the syringe needs to be removed from the clamping device, it is only necessary to pull the syringe body out of the hollow channel 4, and the hollow channel 4 is deformed under the action of force to allow the syringe body to pass through. Due to the setting of the hollow structure 3, the syringe head and the needle will not have a limited collision with the clamping device, so no force will be applied to the syringe head and the needle when the syringe body is pulled out, thereby avoiding leakage or damage of the syringe and the needle during the removal process, and reducing the risk of occupational exposure of medical personnel in the early stage of blood gas analysis.

[0028] Embodiment 2:

[0029] See also Figure 4 , this embodiment provides a clamping device.

[0030] The clamping device comprises two clamping plates 7 arranged opposite to each other, the bottoms of the two clamping plates 7 are connected as a whole by a connecting plate 8, and the two clamping plates 7 can be deformed along the connecting plate 8, the upper parts of the two clamping plates 7 are bent inwards, and the inward bending of the upper parts can form a tubular groove for stably clamping the syringe body, and the inward bending can be wavy. The front and rear sides of the two clamping plates 7 are hollow structures, the lower part 10 of the hollow structure allows the syringe head to pass through, and the upper part 9 of the hollow structure can allow the syringe body to pass through after the clamping plates 7 are deformed.

[0031] When the syringe needs to be installed, the syringe is pressed into the hollow structure, causing the clamping plate 7 to deform. This deformation enlarges the gap of the hollow structure to allow the syringe to pass through. The lower part 10 of the hollow structure allows the syringe head to pass through without colliding with the syringe head and the needle. The upper part 9 of the hollow structure can allow the syringe body to pass through after the clamping plate 7 is deformed. The upper part of the clamping plate 7 is not corresponding to the tubular clamping groove formed by inward bending. This structure can stably clamp the syringe body.

[0032] When the syringe needs to be removed, the syringe body is pressed to push the syringe out of the hollow structure.

[0033] Embodiment three:

[0034] See also Figure 5 , this embodiment provides a rotor structure using a clamping device.

[0035] The bottom of the rotor structure is provided with a plug centering 11, which is used to match the end of the syringe, and a side top motor shaft 12 is provided on one side of the bottom of the plug centering 11, which is used to match the motor to drive the plug centering 11 and the clamping device to rotate.

[0036] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto.
