Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, and particularly relates to a plasma bag draining device. BACKGROUND

[0002] Plasma products are medical products taking human blood as raw materials. Enzymes, growth factors and other effective components in plasma can be obtained by separating human blood, and the components have high medical value.

[0003] In the related art, after plasma is extracted from the human body, the plasma is usually stored in a plasma bag. Due to the factors of liquid surface tension and air pressure difference between the inside and outside of the bag, part of the plasma in the plasma bag cannot be smoothly discharged, resulting in waste of the plasma and subsequent burden of biological pollution treatment.

[0004] At present, in order to discharge the residual plasma from the plasma bag, the commonly used method is suspension draining, that is, the discharge port of the plasma bag is directed downward, so that the residual plasma drops under the action of its own gravity. However, the suspension draining consumes a long time and has low plasma discharge efficiency, and thus needs to be improved. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the plasma discharge efficiency, the present application provides a plasma bag draining device.

[0006] The plasma bag draining device provided by the present application adopts the following technical scheme:

[0007] The plasma bag draining device comprises a mounting frame, a rotating shaft rotatably arranged on the mounting frame, a plurality of connecting rods fixedly arranged on the rotating shaft, and a clamping assembly rotatably connected to the connecting rods, wherein the clamping assembly is used for clamping one end of the plasma bag which is not provided with a discharge port.

[0008] By adopting the above technical scheme, when it is necessary to discharge the plasma in the plasma bag, the discharge port of the plasma bag can be closed first, and then the one end of the plasma bag which is not provided with the discharge port is clamped on the clamping assembly. In the natural state, the plasma bag is in a vertical state. Finally, the rotating shaft is controlled to rotate, so that the clamping assembly rotates around the connecting rods, and then the plasma bag rotates from the vertical state to the horizontal state. When the plasma bag rotates with the connecting rods, the plasma is affected by the centrifugal force and flows to the side with the discharge port. When the plasma in the plasma bag flows to the side with the discharge port, the rotating of the rotating shaft is stopped, and the plasma bag returns to the vertical state. At this time, the plasma accumulates at the lower end of the plasma bag and will not flow to the side of the plasma bag which is not provided with the discharge port due to gravity. After the plasma bag is removed, the discharge port is opened, and the plasma can be discharged from the discharge port. Compared with the suspension draining, the time for the plasma to drop by its own gravity is saved, and the plasma discharge efficiency is improved.

[0009] Optionally, the mounting frame comprises a shell, a positioning ring located above the shell, a plurality of support rods arranged on the positioning ring, and the ends of the support rods away from the positioning ring are arranged on the shell, and a gap channel for the plasma bags to extend into the shell is formed between adjacent support rods.

[0010] By adopting the above technical scheme, when the rotating shaft rotates, the positioning ring and the support rods can limit the rotating shaft, so that the rotating shaft is not easy to shake at will, and the stability of the rotating shaft is high. When the plasma bag needs to be fixed on the clamping assembly, the plasma bag can be extended from the gap channel and then clamped on the clamping assembly. If the plasma bag accidentally falls off the clamping assembly during rotation, the plasma bag will be blocked inside the shell and will not fly out of the shell, so that the overall stability and safety of the device are high.

[0011] Optionally, the mounting frame further comprises a first bearing arranged on the shell and a second bearing arranged on the positioning ring, and the rotating shaft is arranged to rotate through the first bearing and the second bearing.

[0012] By adopting the above technical scheme, when the rotating shaft rotates, the first bearing reduces the friction between the rotating shaft and the mounting frame, and the second bearing reduces the friction between the rotating shaft and the positioning ring, so that the rotating shaft rotates more smoothly.

[0013] Optionally, the upper end of the rotating shaft is provided with a hand lever.

[0014] By adopting the above technical scheme, when the rotating shaft needs to be rotated, the hand lever can be rotated to drive the rotating shaft to rotate, which is convenient to operate.

[0015] Optionally, the clamping assembly comprises a first clamping piece, a second clamping piece, and a reset torsional spring for driving one end of the first clamping piece and the second clamping piece to move towards each other, the first clamping piece and the second clamping piece each comprise a hand holding part, a clamping part, and a middle part arranged between the hand holding part and the clamping part, the middle part of the first clamping piece and the middle part of the second clamping piece are connected by hinging, one end of the reset torsional spring abuts against the hand holding part of the first clamping piece, and the other end of the reset torsional spring abuts against the hand holding part of the second clamping piece, the clamping part is used for clamping the plasma bag, the end of the connecting rod away from the rotating shaft is provided with a connecting hook, and the hand holding part is provided with a connecting hole for the connecting hook to pass through.

[0016] By adopting the technical scheme, when the plasma bag needs to be clamped, the hand-held portion of the first clamping piece and the second clamping piece is pressed, so that the spacing between the two clamping portions is increased, then the plasma bag is placed between the two clamping portions, and the clamping portions can clamp the plasma bag under the action of the reset torsional spring by releasing the hand-held portion. When the rotating shaft rotates, the clamping assembly can rotate around the connecting rod due to the connecting hook being arranged in the connecting hole, and then the plasma bag is turned to a horizontal state. When the plasma bag needs to be taken off the clamping assembly, the hand-held portion is pressed, so that the plasma bag can be taken out of the clamping assembly, and the operation is convenient.

[0017] Optionally, a plurality of reinforcing rods are arranged between the rotating shaft and the connecting rod.

[0018] By adopting the technical scheme, the reinforcing rods can improve the stability of the connection between the connecting rod and the rotating shaft, so that the connecting rod is not easy to fall off the rotating shaft, and the stability of the whole device is high.

[0019] Optionally, one end of the supporting rod is hingedly arranged on the shell, and the other end is detachably connected to the positioning ring. A positioning block is arranged on the end of the supporting rod close to the positioning ring. A positioning groove is arranged on the positioning ring and used for clamping the positioning block.

[0020] By adopting the technical scheme, when the plasma bag needs to be taken out, the positioning block can be moved out of the positioning groove, so that the supporting rod is detached from the positioning ring. Then the supporting rod is rotated away from the rotating shaft, so that the supporting rod is no longer above the clamping assembly. Then the supporting rod is not easy to hinder the hand to enter the shell to operate the clamping assembly, the operation space is increased, and the operation is convenient.

[0021] Optionally, an elastic pad is arranged on the groove wall of the positioning groove.

[0022] By adopting the technical scheme, when the supporting rod is connected to the positioning ring, the elastic pad can increase the friction between the supporting rod and the groove wall of the positioning groove, so that the connection strength between the supporting rod and the positioning ring is high.

[0023] Optionally, a limiting groove is arranged on the positioning block and used for clamping the elastic pad.

[0024] By adopting the technical scheme, when the positioning block is inserted into the positioning groove, the elastic pad can be elastically deformed and inserted into the limiting groove. The groove wall of the limiting groove can be tightly attached to the elastic pad, so that the contact area between the elastic pad and the positioning block is increased, and then the friction between the elastic pad and the positioning block is large, and the connection between the supporting rod and the positioning ring is more stable.

[0025] Optionally, the rotating shaft comprises a fixed portion and a movable portion. The fixed portion is provided with a fixed block. The movable portion is provided with a fixed groove. The fixed block and the fixed groove are in interference fit. The connecting rod and the reinforcing rod are arranged on the movable portion.

[0026] By adopting the technical scheme, when the plasma bag needs to be taken out, the support rod can be removed from the positioning ring, then the support rod is rotated in a direction away from the rotating shaft, so that the support rod is no longer located above the clamping assembly, then the movable part is pulled in a direction away from the fixed part, so that the fixed block moves out of the fixed slot, finally the whole movable part, the positioning ring and the second bearing are taken out from the shell and placed outside the shell, then the plasma bag can be taken off from the clamping assembly. By taking out the plasma bag in the above manner, the hand does not need to be repeatedly inserted into the shell, all the plasma bags can be taken out from the shell at one time, the time required for repeated actions is shortened, and manpower is saved.

[0028] 1. The device makes the plasma in the plasma bag flow to one side of the discharge port by centrifugal force, facilitates the discharge of the plasma from the discharge port after the plasma bag is taken off, and improves the efficiency of plasma discharge.

[0029] 2. The clamping assembly is arranged to facilitate the placement and taking out of the plasma bag, and the operation is convenient.

[0030] 3. When the plasma bag needs to be taken out, the support rod can be removed from the positioning ring, then the support rod is rotated to a position that does not block the clamping assembly, then the movable part is separated from the fixed part, and all the plasma bags can be taken out at one time, thereby saving manpower.
