Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary tools technology, and in particular to a plasma bag protection device. Background Technology
[0002] Plasma separation is a common procedure in medical and bioengineering experiments. Plasma separation requires the use of a plasma separator, which is equipped with plasma bags for storing plasma and a weighing scale for weighing the separated plasma. The plasma separator can separate the plasma components in the blood and transport them to the plasma bags. The operator hangs the plasma bags containing the plasma on the weighing scale.
[0003] Currently, the weighing scale is located on the side of the plasma separator closer to the separator. Therefore, when the plasma bag is hung on the weighing scale, it is located outside the separator, making it susceptible to external contact. This could cause the plasma bag to rupture, contaminating the plasma and posing a health risk. It could also affect the weighing value of the plasma, thus hindering the safe use and accurate measurement of the plasma separator. Utility Model Content
[0004] In view of this, the present invention aims to provide a plasma bag protection device to improve the safe use and measurement accuracy of plasma separators.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A plasma bag protection device includes a plasma separator body and a weighing scale, which is installed on the plasma separator body and used to hang plasma bags.
[0007] A protective mechanism is provided on the main body of the plasma separator and includes a bracket located below the weighing scale, a top-opening cylinder on the bracket, and a first and second annular protective members disposed within the cylinder. The protective mechanism has at least a retracted state and an extended state. In the retracted state, the first and second protective members are sequentially retracted into the cylinder along the height direction of the main body of the plasma separator. In the extended state, the first and second protective members extend sequentially out of the cylinder along the height direction of the main body of the plasma separator, forming a protective barrier for the plasma bag.
[0008] The tray mechanism includes a drive unit disposed on the main body of the plasma separator, and a tray that is driven to rise and fall by the drive unit, the tray being used to fix the plasma bag.
[0009] Furthermore, the main body of the plasma separator is equipped with a pulley assembly;
[0010] The pallet mechanism also includes a rope that bypasses the pulley assembly and is connected at both ends to the pallet and the first guard member, respectively, and the rope is driven to be connected to the drive unit.
[0011] Furthermore, under the drive of the driving unit, the rope can move the tray to the bottom of the cylinder and simultaneously drive the first guard to rise until it and the second guard extend out of the cylinder in sequence along the height direction of the plasma separator body to form the unfolded state.
[0012] Furthermore, the inner wall of the second guard member is provided with a guide groove extending along the height direction, and the first guard member is provided with a guide block adapted to the guide groove. The first guard member is slidably disposed in the guide groove through the guide block.
[0013] Furthermore, the tray is provided with snap-fit holes for securing the opening of the plasma bag.
[0014] Furthermore, the bracket is provided with fasteners, which pass through the bracket from bottom to top and are screwed onto the cylinder.
[0015] Compared with the prior art, this utility model has the following advantages:
[0016] The plasma bag protection device of this utility model, through the cylinder in the protective mechanism, the first and second protective components housed in the cylinder, and the drive unit and tray in the tray mechanism, can realize the deployment of the protective mechanism and form protection for the plasma bag, which can prevent the plasma bag from breaking due to external contact, thereby improving the safe use of the main body of the plasma separator.
[0017] Secondly, the tray and the first guard are connected by a rope, which is also connected to the drive unit. This allows for synchronous movement of the tray and the first guard, ensuring that both move along the height of the plasma separator body. The structure is simple and easy to design and implement. The drive unit moves the rope to the bottom of the cylinder, simultaneously lifting the first guard until the second guard extends out of the cylinder, thus facilitating its unfolding state and providing protection for the plasma bag.
[0018] Furthermore, by setting guide grooves and guide blocks, the first guard can slide stably within the second guard, and the first guard can be effectively prevented from detaching when it extends beyond the second guard. Snap-fit holes on the tray facilitate the securing of the plasma bag. Fasteners on the bracket secure the guard mechanism, ensuring the stability of the device and facilitating its assembly and disassembly. Attached Figure Description

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0044] Example 1
[0045] This embodiment relates to a plasma bag protection device, which can prevent the plasma bag from rupturing due to external contact, keeping the plasma bag in a safe environment, thereby improving the safe use and measurement accuracy of the plasma separator.
[0046] In terms of overall structure, such as Figures 1 to 12 As shown, the plasma bag protection device of this embodiment includes a plasma separator body 1, a weighing scale 11 disposed on the plasma separator body 1 for hanging plasma bags, a guarding mechanism 2 disposed on the plasma separator body 1, and a tray mechanism 3.
[0047] The protective mechanism 2 includes a bracket 21 located below the weighing scale 11, a cylindrical body 24 with an open top on the bracket 21, and a first protective member 22 and a second protective member 23, both in annular shape, disposed inside the cylindrical body 24. The protective mechanism 2 has at least a retracted state and an extended state. In the retracted state, the first protective member 22 and the second protective member 23 are sequentially retracted into the cylindrical body 24 along the height direction of the plasma separator body 1. In the extended state, the first protective member 22 and the second protective member 23 extend out of the cylindrical body 24 along the height direction of the plasma separator body 1, forming a protective barrier for the plasma bag.
[0048] Meanwhile, the tray mechanism 3 includes a drive unit 31 located on the main body 1 of the plasma separator, and a tray 32 driven to rise and fall by the drive unit 31. The tray 32 is used to fix the plasma bag.
[0049] At this point, with the above configuration, the first and second protective members 22 and 23 housed within the cylinder 24 of the protective mechanism 2, along with the drive unit 31 and tray 32 in the tray mechanism 3, enable the protective mechanism 2 to unfold and protect the plasma bag. This prevents the plasma bag from rupturing due to external contact, thereby improving the safe usability of the plasma separator body 1. Furthermore, setting the first and second protective members 22 and 23 in a ring shape facilitates adequate protection of the plasma bag and also simplifies design and implementation.
[0050] Based on the above overview, in this embodiment, as a preferred implementation, refer to... Figures 2 to 4 As shown, the main body 1 of the plasma separator is provided with a pulley assembly 4, and the tray mechanism 3 also includes a rope 33 that passes around the pulley assembly 4 and is connected at both ends to the tray 32 and the first guard 22 respectively. The rope 33 and the drive unit 31 are drivenly connected.
[0051] Here, the tray 32 and the first guardrail 22 are connected by a rope 33, and the rope 33 is driven by the drive unit 31. This allows the tray 32 and the first guardrail 22 to move synchronously, and both the tray 32 and the first guardrail 22 to move along the height of the plasma separator body 1. The structure is simple and easy to design and implement. Specifically, the guardrail mechanism 2 has mounting brackets 41 on both sides, and the pulley assembly 4 is mounted on the mounting brackets 41.
[0052] Specifically, in this embodiment, as a preferred implementation, it still refers to... Figure 1 and Figure 3 As shown, under the drive of the drive unit 31, the rope 33 can move the tray 32 to the bottom of the cylinder 24 and simultaneously drive the first guard 22 to rise until it and the second guard 23 extend out of the cylinder 24 in sequence along the height direction of the plasma separator body 1 to form an unfolded state.
[0053] Furthermore, in this embodiment, based on the cylinder 24 and each protective component in the protective mechanism 2 described above, and the connection between the first protective component 22 and the tray 32, under the drive of the drive unit 31, the tray 32 descends along the height direction of the plasma separator to the bottom of the cylinder 24, while the first protective component 22 is driven to rise by the rope 33, thereby driving the second protective component 23 to rise.
[0054] At this time, the first guardrail 22 moves relative to the second guardrail 23, and the second guardrail 23 moves relative to the cylinder 24, that is, the first guardrail 22 and the second guardrail 23 move up and down in the unfolding and retracting direction of the guardrail mechanism 2. Of course, driven by the drive unit 31 and with the cooperation of the tray 32 and the first guardrail 22, this embodiment can realize the driving of the first guardrail 22 and the second guardrail 23 through the connection between the guardrails to achieve the switching between the unfolded state and the retracted state.
[0055] At the same time, it is understandable that under the drive of the drive unit 31, the tray 32 is lowered to drive the first guard 22 to rise, and the first guard 22 drives the second guard 23 to extend out of the cylinder 24. This can specifically realize the raising of the first guard 22 and the second guard 23, so as to meet the usage requirements of the plasma separator body 1 and achieve the purpose of protecting the plasma bag.
[0056] like Figures 7 to 9As shown in the illustration, in this preferred embodiment, the inner wall of the second guard member 23 is provided with a guide groove 51 extending along the height direction, and the first guard member 22 is provided with a guide block 52 adapted to the guide groove 51. The first guard member 22 is slidably disposed in the guide groove 51 via the guide block 52. The advantage of this arrangement is that by providing the guide groove 51 and the guide block 52, the first guard member 22 can slide stably in the second guard member 23, and the first guard member 22 can be effectively prevented from detaching when it extends out of the second guard member 23.
[0057] At the same time, it should be noted that, referring to Figure 10 and Figure 11 As shown, a guide groove 51 is provided on the inner side wall of the cylinder 24, and a guide block adapted to the guide groove 51 is provided on the second guard 23. The second guard 23 is slidably disposed in the guide groove 51 through the guide block 52. Thus, the second guard 23 can be stably slid in the cylinder 24, effectively preventing the second guard 23 from falling off.
[0058] In addition, in this embodiment, as a preferred implementation, such as Figure 12 As shown, the tray 32 has a snap-fit hole 321 for securing the opening of the plasma bag. This secures the plasma bag when it is hung on the weighing scale 11, preventing it from shaking. It is worth noting that the snap-fit hole 321 only secures the plasma bag and does not support it; therefore, it does not affect the weighing value during use.
[0059] In addition, in this embodiment, as a preferred implementation, such as Figure 5 and Figure 6 As shown, the bracket 21 is equipped with a fastener 6, which runs from bottom to top through the bracket 21 and is screwed onto the cylinder 24. The cylinder 24 and the bracket 21 are connected by the fastener 6, which helps to ensure the stability of the device and also facilitates the disassembly and assembly of the guard mechanism 2.
[0060] When the plasma bag protection device of this embodiment is in use, as mentioned above, when the plasma bag is hung on the weighing scale 11, the tray 2 descends to the bottom of the cylinder 24 under the drive of the drive unit 31. At the same time, the rope 33 slides on the pulley assembly 4 to pull the first guard 22 up until it extends out of the cylinder 24 along with the second guard 23 to form protection for the plasma bag.
[0061] In summary, the plasma bag protection device of this embodiment adopts the above design. By making the protective mechanism 2 include a first protective member 22, a second protective member 23 and a cylinder 24, it can cooperate with the tray 32 to prevent the plasma bag from breaking due to external contact, so that the plasma bag is in a safe environment, thereby improving the safe use and measurement accuracy of the plasma separator.
[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
