[0002] At present, when blood gas testing is performed clinically, the sample processing requirements are very strict. It is often the case that the sample cannot be used due to abnormal measurement results caused by poor sample processing. When processing samples, the requirements for users (doctors, nurses) are very high, and usually they need to be trained and qualified before they can operate. This situation is particularly obvious for some hospitals with teaching nature.

[0029] Please refer to Figures 1 to 6 The utility model provides a mixing device suitable for syringes of different specifications, including a plurality of spring pressure rod assemblies 2 and a mixing assembly 3, wherein the spring pressure rod assemblies 2 can be relatively close to or far away from the mixing assembly 3, and a syringe 1 is inserted between each spring pressure rod assembly 2 and the mixing assembly 3;

[0030] The spring pressure rod assembly 2 includes a pressure rod member 21, one end of which is connected to a pulling member 22. Pulling or releasing the pulling member 22 can drive the pressure rod member 21 away from or close to the mixing assembly 3. The other end is provided with a clamping unit 23 that can be used to clamp syringes 1 of different specifications.

[0031] In this embodiment, the mixing device includes a plurality of spring pressure rod assemblies 2 and a mixing assembly 3, each spring pressure rod assembly 2 can be close to or away from the mixing assembly 3, and a syringe 1 is inserted between the spring pressure rod assembly 2 and the mixing assembly 3. The spring pressure rod assembly 2 and the mixing assembly 3 can clamp the syringe 1, and the mixing assembly 3 is used to mix the sample in the syringe 1.

[0032] When the syringe 1 needs to be inserted into the mixing device, first pull the spring pressure rod assembly 2 in the direction away from the mixing component 3, insert the syringe 1 between the mixing component 3 and the spring pressure rod assembly 2, and then move the spring pressure rod assembly 2 toward the mixing component 3, so that the syringe 1 is clamped between the spring pressure rod assembly 2 and the mixing component 3, and the sample in the syringe 1 is mixed by the mixing component 3.

[0033] Specifically, the spring pressure rod assembly 2 includes a pressure rod member 21, and the two ends of the pressure rod member 21 are respectively connected to a pulling member 22 and a clamping unit 23. The pulling member 22 is used to pull the pressure rod member 21 to move toward or away from the mixing component 3, so that it is more convenient to clamp or sample the syringe 1 between the spring pressure rod assembly 2 and the mixing component 3; the clamping unit 23 is used to clamp syringes 1 of different specifications, and can automatically mix the sample in the syringe 1.

[0034] In this embodiment, multiple spring pressure rod assemblies 2 are provided, which can realize the simultaneous use of syringes 1 of different specifications, and can realize the simultaneous shaking of samples in multiple syringes 1. In addition, the speed, time and other parameters of the mixing assembly 3 can be adjusted, which can effectively avoid abnormal measurement results due to unqualified mixing of clinical samples, and is compatible with the simultaneous mixing of multiple samples.

[0035] Furthermore, the clamping unit 23 includes two clamping rods 231 arranged opposite to each other, and a first spring member 232 is connected between the two clamping rods 231 . The two clamping rods 231 can be relatively moved closer or farther away from each other through the first spring member 232 to clamp syringes 1 of different specifications.

[0036] In the present embodiment, the clamping unit 23 includes two clamping rods 231, the two clamping rods 231 are arranged opposite to each other, and a first spring member 232 is connected between the two clamping rods 231. The two clamping rods 231 can be relatively close to or away from each other through the first spring member 232, so as to be used to clamp syringes 1 of different specifications. Specifically, the first spring member 232 is stretched, so that the distance between the two clamping rods 231 becomes larger, so as to be suitable for syringes 1 of different specifications. Among them, the first spring member 232 is specifically a tension spring in the present embodiment, and the specific type of the first spring member 232 is not limited here, and is set according to actual production requirements.

[0037] Furthermore, one end of the two clamping rods 231 is connected to the pressure rod 21 , and the other end is connected to the bearing 233 . The ends of the two clamping rods 231 connected to the bearing 233 are relatively far apart, and the clamping unit 23 clamps syringes 1 of different specifications through the bearing 233 .

[0038] In this embodiment, one end of the two clamping rods 231 is connected to the pressure rod 21 through a cylindrical pin, so that the pressure rod 21 can drive the two clamping rods 231 to move closer to or away from the mixing component 3, and the end of the clamping rod 231 away from the pressure rod 21 is connected to a bearing member 233, and the ends of the two clamping rods 231 connected to the bearing member 233 are relatively far apart, that is, the spacing between the ends of the two clamping rods 231 connected to the bearing member 233 is greater than the spacing between the ends of the two clamping rods 231 connected to the pressure rod 21.

[0039] Specifically, the two clamping rods 231 clamp syringes 1 of different specifications through the bearing member 233, and the ends of the two clamping rods 231 connected to the bearing member 233 are relatively far away from each other, so that the two clamping rods 231 can better clamp the syringe 1. When the bearing members 233 on the two clamping rods 231 touch the outer wall of the syringe 1, the two clamping rods 231 will open under the stretching action of the first spring member 232, so that the two clamping rods 231 abut the syringe 1 on the rolling shaft 31 through the bearing member 233.

[0040] The syringe 1 is abutted against the rolling shaft 31 by the bearing member 233, and the rotating bearing member 233 can reduce the rotational friction force of the spring pressure rod assembly 2 on the syringe 1. The bearing member 233 is specifically a rubber-coated external threaded bearing in this embodiment.

[0041] Furthermore, a second spring member 211 is sleeved on the pressure rod member 21. When the pulling member 22 is pulled to drive the pressure rod member 21 to move in a direction away from the mixing component 3, the second spring member 211 is compressed; when the pulling member 22 is released, the second spring member 211 is reset and drives the pressure rod member 21 to move in a direction close to the mixing component 3.

[0042] In this embodiment, a second spring member 211 is sleeved on the pressure rod member 21. When the syringe 1 needs to be installed between the spring pressure rod assembly 2 and the mixing assembly 3, only a force needs to be applied to the pulling member 22. When the pulling member 22 drives the pressure rod member 21 to move in a direction away from the mixing assembly 3, the second spring member 211 on the pressure rod member 21 is compressed; when the syringe 1 is inserted between the spring pressure rod assembly 2 and the mixing assembly 3, the pulling member 22 is released, so that the pulling member 22 loses its force, and the second spring member 211 on the pressure rod member 21 will return to its original state and drive the pressure rod member 21 to move in a direction close to the mixing assembly 3.

[0043] Furthermore, the mixing component 3 includes a rolling shaft 31 and a driving member 32 which are connected to each other. The rolling shaft 31 abuts against the syringe 1 , and the driving member 32 can drive the rolling shaft 31 to rotate to drive the syringe 1 to rotate.

[0044] In this embodiment, the mixing component 3 includes a rolling shaft 31 and a driving member 32, which are connected to each other, and the driving member 32 is arranged below the rolling shaft 31. The outer wall of the rolling shaft 31 will abut against the syringe 1, so that when the driving member 32 drives the rolling shaft 31 to rotate, the syringe 1 abutting between the rolling shaft 31 and the bearing member 233 will also rotate, thereby mixing the sample in the syringe 1. Among them, the driving member 32 can also adjust various speed and time parameters, which can effectively avoid abnormal measurement results due to unqualified mixing of clinical samples, and is compatible with mixing multiple samples at the same time.

[0045] Furthermore, it also includes a shell 4, the mixing assembly 3 is arranged in the shell 4, a plurality of spring pressure rod assemblies 2 are connected to the shell 4, and the pulling parts 22 of the spring pressure rod assemblies 2 are exposed outside the shell 4, and the clamping units 23 of the spring pressure rod assemblies 2 are arranged in the shell 4.

[0046] In this embodiment, the mixing device also includes a shell 4, and both the mixing component 3 and the spring pressure rod component 2 have partial structures arranged in the shell 4, and partial structures are exposed outside the shell 4. Specifically, the rolling shaft 31 in the mixing component 3 is arranged in the middle position in the shell 4, and the driving member 32 is arranged below the rolling shaft 31, and a part of the driving member 32 is exposed outside the shell 4; the pulling member 22 of the spring pressure rod assembly 2 is exposed outside the shell 4, which can facilitate the user to pull the pulling member 22 for clamping or sampling, and the clamping unit 23 is arranged in the shell 4 to facilitate it and the rolling shaft 31 to clamp the syringe 1.

[0047] Furthermore, a plurality of first guide grooves 41 are formed on the housing 4 , and the pressing rod 21 is inserted into the housing 4 through the first guide grooves 41 , and the second spring member 211 on the pressing rod 21 abuts against the inner wall of the housing 4 .

[0048] In this embodiment, a plurality of first guide grooves 41 are provided on the outer wall of the housing 4, and the pressure rod 21 is inserted into the housing 4 through the first guide grooves 41, and the pulling member 22 drives the pressure rod 21 to reciprocate in the first guide grooves 41 to drive the clamping unit 23 to move. The second spring member 211 sleeved on the pressure rod 21 also abuts against the inner wall of the housing 4, and when the pulling member 22 drives the pressure rod 21 to move in a direction away from the mixing component 3, that is, when the pressure rod 21 moves in a direction toward the inner wall of the housing 4, the second spring member 211 abuts against the inner wall of the housing 4, so that the second spring member 211 is compressed; when the pulling member 22 is released, the second spring member 211 will move away from the inner wall of the housing 4, and the second spring member 22 will return to its original state, and drive the pressure rod 21 to move in the direction of the mixing component 3.

[0049] Furthermore, the cross section of the pressing rod 21 is D-shaped, and the shape of the first guide groove 41 is matched with the shape of the pressing rod 21 .

[0050] In this embodiment, the cross section of the pressure rod 21 is D-shaped, and the shape of the first guide groove 41 is also adapted to the shape of the pressure rod 21, which can prevent the pressure rod 21 from rotating in the first guide groove 41. The specific cross-sectional shape of the pressure rod 21 is not limited here, and it is only necessary that the pressure rod 21 does not rotate in the first guide groove 41.

[0051] Furthermore, a plurality of second guide grooves 42 for inserting the syringe 1 are provided on the housing 4 .

[0052] In this embodiment, a plurality of second guide grooves 42 are further provided on the top surface of the housing 4 , and the second guide grooves 42 are used for inserting the syringe 1 .

[0053] Furthermore, the opening of the syringe 1 is connected with a plug 11 .

[0054] In this embodiment, the opening of the syringe 1 is connected to a plug 11, so that the syringe 1 can be sealed, thereby preventing the sample in the syringe 1 from spilling out during the mixing process.

[0055] Furthermore, the specific implementation steps of the mixing device suitable for syringes of different specifications are:

[0056] When installing the sample of the syringe 1, the syringe 1 must be sealed with the plug 11 first, and the pulling member 22 of the spring pressure rod assembly 2 installed on the housing 4 is pulled. After the syringe 1 is slowly inserted along the second guide groove 42, the pulling member 22 is released. Under the action of the second spring member 211 installed on the pressure rod member 21, the pressure rod member 21 is reset along the empty position. At this time, after the bearing member 233 hits the outer wall of the syringe 1, the two clamping rod members 231 will open relatively. At the same time, under the action of the first spring member 232 connected between the two clamping rod members 231, the two The rubber-coated external threaded bearing member 233 on the clamping rod member 231 and the rolling shaft 31 clamp the syringe 1 together. At this time, when the rolling shaft 31 is driven by the driving member 32 to rotate, the syringe 1 that collides with the rolling shaft 31 will rotate under the joint pressure of the bearing member 233 and the rolling shaft 31. At the same time, the bearing member 233 can also rotate when pressing the syringe 1 to reduce the rotational friction of the clamping rod member 231 on the syringe 1. When the sample is mixed, the pulling member 22 of the spring pressure rod assembly 2 is pulled to release the syringe 1 and then take it out to use the syringe sample. Among them, the same operation as above can also be used to clamp and shake syringes 1 of different specifications.
