Description

Technical Field

[0001] The present invention relates to the technical field of apheresis platelets, and in particular to an apheresis platelet oscillation storage cooperation structure device and a using method thereof. Background Art

[0002] After apheresis platelets are completed, it is necessary to oscillate and keep warm the platelets for storage. Oscillating and keeping warm the storage is to maintain the activity of the platelets and prevent the platelets from coagulating. Generally, through oscillating and keeping warm the storage, apheresis platelets can be stored for up to 5 days. When storing and placing the blood collection bag of apheresis platelets, the blood collection bag is directly placed on the tray of the oscillating box, and then the oscillating box drives the tray to start periodic swinging to oscillate the platelets in the blood collection bag. This causes some problems: First, the blood collection bag is made of a soft material of polyvinyl chloride. During the oscillation process, the thickness of the liquid in the blood collection bag in the vertical direction is uneven, and there are differences in heat transfer. Second, during oscillation, the soft blood collection bag has a certain resistance to the flow of platelet liquid, and the oscillation amplitude of the platelet liquid in contact with the inner wall of the blood collection bag is insufficient. The above two phenomena are all adverse factors affecting the oscillation storage duration of platelets. Therefore, how to reduce the adverse influence degree of the above two phenomena in the platelet oscillation storage has become a problem to be solved. Summary of the Invention

Two elastic strips with open ends at the side ends are arranged at the side ends of the solid parts. Plastic cardboards are symmetrically installed on the upper and lower sides of the solid parts; When the blood collection bag is placed horizontally, a stainless steel metal sheet is installed between the two plastic cardboards at the same horizontal position; An upper cover plate is installed at the opening position on the upper side of adjacent placement partitions. A magnetic attraction piece for magnetically attracting the stainless steel metal sheet at the upper side position of the horizontally placed blood collection bag is arranged on the bottom side of the upper cover plate.

[0006] As a preferred technical solution of the oscillation storage cooperation structure device in the present invention: Let the height dimension of the edge convex plate protruding from the upper side of the bottom plate of the tray rack be Ha, and let the thickness dimension of the stainless steel metal sheet be Hb, then Ha = Hb.

[0011] The present invention provides a method for using a storage bag and a storage device for apheresis platelets oscillation, including the following steps:

[0012] ㈠ Blood collection bag shaping

[0013] First, before using the blood collection bag for apheresis platelets, install the plastic card boards on both the upper and lower sides of the solid part; then, take out the stainless steel metal sheet that is usually placed in the oscillation box (the temperature in the oscillation box is the appropriate temperature for storing platelets), and insert the stainless steel metal sheet at the positions of the two plastic card boards on the upper side and the two plastic card boards on the lower side of the blood collection bag. When inserting the stainless steel metal sheet, first take out one stainless steel metal sheet and insert it at the bottom side position of the blood collection bag, and then take out the second stainless steel metal sheet and insert it at the upper side of the blood collection bag;

[0014] ㈡ Blood collection bag placement, heat preservation and oscillation preservation

[0015] First, horizontally place the blood collection bag with the stainless steel metal sheet inserted into the placement groove of the tray rack. When placing, press the solid parts on both sides, and through the elastic strips, horizontally place the blood collection bag with the stainless steel metal sheet; then, cover the upper combined cover plate between adjacent placement partitions, and the magnetic attraction sheet at the bottom side of the upper combined cover plate makes magnetic attraction contact with the stainless steel metal sheet on the upper side of the blood collection bag in the placement groove.

[0018] 2. In the present invention, by providing magnetic attraction sheets on the bottom side of the upper cover plate, the magnetic attraction sheets magnetically attract the stainless steel metal sheets at the upper positions, lifting the bag skin at the upper positions of the blood collection bag to a certain extent. The bag skin at the upper positions of the blood collection bag will not exert excessive pressure on the platelet liquid, reducing the inhibitory effect on platelet flow and making the flow effect of platelets in the blood collection bag better during oscillation.

The height dimension of the edge convex plate 202 protruding from the upper side of the bottom plate of the tray rack 2 is the same as the thickness dimension of the stainless steel metal sheet 4, so as to prevent the combination of the blood collection bag 3 and the stainless steel metal sheet 4 from falling out of the placing groove 203.

[0034] Please refer to Figure 3 , when the blood collection bag 3 is placed horizontally, a stainless steel metal sheet 4 is installed between two plastic card boards 303 at the same horizontal position. The stainless steel metal sheet 4 in the present invention is a rigid metal sheet, that is, a metal sheet that is not easily deformed, so as to support the blood collection belt relatively flat.

[0035] Please refer to Figure 4 , Figure 7, on both sides of the blood collection bag 3, solid parts 301 made of polyvinyl chloride are provided. At the side ends of the solid parts 301, two elastic strips 302 with disconnected side ends are provided. The elastic strips 302 are extensions of the solid parts 301. The elastic strips 302 made in an extended shape are for having a certain installation allowance when placing the blood collection bag 3 supported and unfolded by the stainless steel metal sheet 4 in the placement groove 203, so as to conveniently and easily place the blood collection bag 3. Plastic clamping plates 303 are symmetrically installed on the upper and lower sides of the solid part 301. A support clamping opening 304 is formed between the plastic clamping plates 303 installed at the position of the solid part 301 and the blood collection bag.

[0036] Please refer to Figure 5 , on both sides of the stainless steel metal sheet 4, card edge plates 401 are provided. Combining Figure 4 , the card edge plates 401 on both sides of the stainless steel metal sheet 4 are cooperatively installed at the position of the support clamping opening 304.

The magnetic sheet 501 is used to magnetically attract the stainless steel metal sheet 4 at the upper side position of the horizontally placed blood collection bag 3. Clamping notches 502 are opened at both side positions of the upper cover plate 5. The clamping notches 502 cooperate with the placement partition 201. The width dimension of the upper cover plate 5 matches the spacing dimension between adjacent placement partitions 201. A hand-holding groove 503 is opened on the top side of the upper cover plate 5. The upper cover plate 5 is taken and placed through the hand-holding groove 503.

[0038] Please refer to Figure 7 , when the blood collection bag 3 is placed vertically, plastic clamping plates 303 are installed on the front and rear side surfaces of the solid part 301 of the blood collection bag 3. A support clamping opening 304 is formed between the plastic clamping plates 303 and the bag skin of the blood collection bag 3.

The lower end of the limit insertion post 306 is a spherical structure. The innermost part of the reserved hole slot 305 is also a spherical slot. In this way, after the limit insertion post 306 is inserted into the reserved hole slot 305 with force, the plastic clamping plates 303 can be relatively firmly installed at the position of the solid part 302. Embodiment 2:

[0041] The present invention relates to a method of using a single - donor platelet oscillation storage cooperation structure device, including the following steps: blood collection bag shaping, blood collection bag placement, temperature - controlled oscillation preservation, etc.

[0042] (I) Blood collection bag shaping: First step, before using the blood collection bag 3 for single - donor platelet collection, install the plastic cardboards 303 on the upper and lower sides of the solid part 301. Second step, take out the stainless - steel metal sheet 4 that is usually placed in the oscillation box 1. The temperature in the oscillation box 1 is the suitable temperature for storing platelets. At this time, the temperature of the stainless - steel metal sheet 4 is also close to the suitable temperature for storing platelets in the oscillation box 1, and to a certain extent, it starts the "ambient temperature intervention" at the suitable temperature for platelets. Insert the stainless - steel metal sheet 4 at the positions of the two plastic cardboards 303 on the upper side and the two plastic cardboards 303 on the lower side of the blood collection bag 3. When inserting the stainless - steel metal sheet 4, first take out one stainless - steel metal sheet 4 and insert it at the bottom side of the blood collection bag, and then take out the second stainless - steel metal sheet 4 and insert it at the upper side of the blood collection bag.

[0043] (II) Blood collection bag placement, temperature - controlled oscillation preservation: First step, horizontally place the blood collection bag with the stainless - steel metal sheet 4 inserted into the placement groove of the tray rack 2. When placing, press the solid parts 301 on both sides, and through the elastic strip 302, horizontally place the blood collection bag 3 with the stainless - steel metal sheet 4. In the present invention, the stainless - steel metal sheet 4 is inserted on both the upper and lower sides of the blood collection bag 3. When heat transfer occurs, the entire stainless - steel metal sheet 4 evenly dissipates heat at each position in contact with the blood collection bag 3, so that the platelet liquid at each position in the blood collection bag 3 can obtain a more suitable temperature, ensuring the preservation quality of the platelets in the blood collection bag 3. Second step, cover the upper cover plate 5 between adjacent placement partitions 201. The magnetic attraction piece 501 at the bottom side of the upper cover plate 5 makes magnetic contact with the stainless - steel metal sheet 4 on the upper side of the blood collection bag 3 in the placement groove 203. When the stainless - steel metal sheet 4 at the upper side position lifts the blood collection bag 3 to a certain extent, the bag skin at the upper side position of the blood collection bag will not cause excessive pressure on the platelet liquid, reducing the inhibitory effect on platelet flow, and making the platelet flow effect better when the blood collection bag 3 oscillates. After covering the upper cover plate 5 on the tray rack 2, the door body of the oscillation box 1 can be closed, and then the oscillation operation of the oscillation box 1 on the tray rack 2 can be started.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
