Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a blood homogenizing device for transfusion pretreatment. Background Technology

[0002] Currently, before blood transfusion, the blood bag needs to be shaken and warmed according to its condition. Shaking the blood bag is done for the following reasons: to prevent component precipitation: During storage, formed elements (such as red blood cells) may settle at the bottom of the blood bag, while plasma floats on top; if it is not shaken, the transfused blood components may be uneven, affecting the treatment effect; to reduce transfusion reactions: Uneven blood components may cause an imbalance of blood components in the recipient's body, increasing the risk of transfusion reactions.

[0003] The reasons for warming blood bags are as follows: Firstly, to increase blood temperature: refrigerated blood is at a low temperature, and direct transfusion may cause a drop in the recipient's body temperature, leading to adverse reactions such as chills and fever. Warming the blood brings it closer to normal body temperature, reducing discomfort. Secondly, to reduce blood viscosity: blood becomes more viscous at low temperatures; heating reduces this viscosity, making the transfusion process smoother. Thirdly, to improve oxygenation efficiency: warm blood binds more easily to oxygen, improving post-transfusion oxygenation efficiency.

[0004] However, in the existing technology, when shaking and heating blood bags, two different devices are needed to shake and heat them separately, which results in a longer pre-treatment cycle for blood bags before transfusion, reducing the efficiency of transfusion operations. Moreover, the need to use two different devices increases the pre-treatment cost before transfusion. Summary of the Invention

[0040] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] Please refer to Figures 1-8 This embodiment provides a blood mixing device 100 for blood transfusion pretreatment, which includes a main body 110, a heating unit 120 and a plurality of mixing units 130.

[0042] The main body 110 is equipped with a central column 111; multiple shaking units 130 are connected to the main body 110 and arranged in a ring array around the axis of the central column 111; the heating unit 120 is rotatably connected to the central column 111 and can move along the axis of the central column 111.

[0043] The shaking unit 130 is used to place and shake the blood bag; the heating unit 120 is used to rotate relative to the central column 111 and move along the axis of the central column 111 under the action of external force, so as to heat the blood bag in one of the shaking units 130.

[0044] Please refer to Figures 1-8 The working principle of the blood homogenizing device 100 for transfusion pretreatment is as follows:

[0045] First, the purpose of the blood pretreatment blood mixing device 100 during use is to pretreat the blood bag before transfusion. The pretreatment method is based on the state of the blood bag, including shaking the blood bag or heating it to reheat it; or the blood bag can be shaken and heated to reheat simultaneously.

[0046] Based on this, the blood mixing device 100 for transfusion pretreatment includes a main body 110, a heating unit 120 and a plurality of mixing units 130.

[0047] Multiple shaking units 130 are connected to the main body 110 and arranged in a ring array around the axis of the central column 111; each shaking unit 130 is used to contain a blood bag and to shake the blood bag inside it by swinging.

[0048] During this process, if it is confirmed that the blood bag needs to be heated and rewarmed based on its temperature status, the heating unit 120 can be operated to rotate around the central column 111. When it rotates to a position directly above the corresponding shaking unit 130, it can be moved along the axis of the central column 111 to get close to the shaking unit 130. Then, when it is in a position of contact or abutment with the shaking unit 130, the blood bag in the shaking unit 130 can be heated by the heating unit 120 delivering hot air into the shaking unit 130 or by the heating unit 120 generating heat.

[0049] It should be noted that, through the above structural arrangement, the position of the heating unit 120 can be adjusted according to the needs of use, so that it can heat the blood bag in one of the shaking units 130. The heating method can be to deliver hot air into the shaking unit 130, or to heat the blood bag by generating heat through thermal radiation. Moreover, since there are multiple shaking units 130, the heating unit 120 can be selected to heat one of the shaking units 130, while the other shaking units 130 are in normal shaking operation.

[0050] Furthermore, as can be seen from the above, the structural arrangement allows the heating unit 120 and the multiple shaking units 130 to operate independently. Therefore, the heating unit 120 can heat the blood bag within one of the shaking units 130; and one or more of the shaking units 130 can be in operation. This arrangement aims to simultaneously shake one or more blood bags when the device is located in a blood bank or nurse's station, thereby expanding its applicability, increasing its efficiency, and reducing operating costs. The heating unit 120 can precisely control the temperature and has an overheat prevention function to avoid damaging blood proteins or causing hemolysis during heating. For example, its operating temperature can be limited to near room temperature (20-25°C) or to 35-37.5°C, close to body temperature (37°C).

[0051] In summary, please refer to the following: Figures 1-8The blood shaking device 100 for transfusion pretreatment can shake and heat the blood bag before transfusion, thus completing the pretreatment work before transfusion with a single device. This can shorten the pretreatment cycle of blood bags before transfusion, improve the efficiency of transfusion operation, and reduce the pretreatment cost before transfusion because the device can simultaneously shake and heat the blood bag.

[0052] Further, please refer to Figures 1-8 Based on the above structure, since the device is used in blood banks or nurse stations, when it can pre-process blood bags, based on its structural configuration, especially the distribution of multiple shaking units 130 around the axis of the central column 111, the blood shaking device 100 for transfusion pre-processing may also include a centrifugal ring 140 rotatably disposed on the outer periphery of the main body 110. That is, the centrifugal ring 140 can be configured based on the aforementioned annular arrangement of the shaking units 130 and the rotational configuration of the heating unit 120. Moreover, the centrifugal ring 140 is located relative to the outer periphery of the main body 110, the purpose of which is to avoid interference with the blood bags processed inside when centrifuging the blood collection tubes.

[0053] Specifically, to achieve centrifugal processing of blood collection tubes, the centrifugal ring 140 is equipped with multiple centrifugal mounting positions 141 for mounting blood collection tubes; the axis of the centrifugal ring 140 coincides with the axis of the central column 111. Furthermore, to drive the centrifugal ring 140 to rotate during use, a rotary motor 142 is installed inside the main body 110. The rotary motor 142 is connected to the centrifugal ring 140 and is used to drive the centrifugal ring 140 to rotate around its axis.

[0054] It should be noted that, based on the above, the device can process blood bags and blood collection tubes simultaneously. Therefore, for ease of control, a first operating table 112 is provided outside the main body 110. The first operating table 112 can control the operation of multiple shaking units 130 and centrifugal ring 140. A second operating table 113 is provided on the heating unit 120 to control the heating unit 120. In addition, for ease of operation, all the aforementioned controls can be integrated into the first operating table 112 or the second operating table 113.

[0055] As can be seen from the above, in this embodiment, when heating the blood bag, it can be heated by transmitting hot air or by thermal radiation. In this embodiment, hot air is used as an example to improve the uniformity of heating and avoid overheating.

[0056] To achieve the above-mentioned heating method for hot air, a heating structure is installed inside the main body 110, which can transmit hot air to the heating unit 120. When the heating unit 120 and the shaking unit 130 are in the correct positions, the hot air can be transmitted to the shaking unit 130 for heating. Specifically, the central column 111 is a hollow tube. Its purpose is to guide the hot air generated inside the main body 110 to move towards the heating unit 120.

[0057] The main body 110 is equipped with a temperature regulating pipe 151, a temperature regulating unit 152, and a fan unit 153. The temperature regulating pipe 151 is located inside the main body 110, with its lower end open to communicate with the outside, and its upper end connected to the central column 111. The temperature regulating unit 152 and the fan unit 153 are both built into the temperature regulating pipe 151. The upper end of the temperature regulating pipe 151 is provided with an exhaust port 154. The exhaust port 154 is connected to the heating unit 120 to deliver airflow to the heating unit 120. Thus, since the lower end of the temperature regulating pipe 151 is open, when the temperature regulating unit 152 and the fan unit 153 are working, the airflow can be guided into the temperature regulating pipe 151 by the fan unit 153, and when it becomes hot airflow after passing through the temperature regulating unit 152, it can be guided to be delivered to the heating unit 120 through the exhaust port 154. The temperature regulating unit 152 is a heating plate.

[0058] In order to enable the heating unit 120 to receive the hot airflow and guide it to the shaking unit 130, the heating unit 120 includes a movable connection part 121 and a heating body 122. The movable connection part 121 is movably connected to the central column 111, and the movable connection part 121 covers the area of ​​the temperature regulating tube 151 where the exhaust hole 154 is opened.

[0059] The movable connection part 121 is provided with a first air guide channel 123, and the heating body 122 is provided with a second air guide channel 124 communicating with the first air guide channel 123, and a plurality of air outlets 125 communicating with the second air guide channel 124.

[0060] Among them, multiple air vents 125 are used to deliver airflow toward the shaking unit 130 when the movable connection 121 moves downward along the axis of the central column 111, so that the heating body 122 is located directly above one of the shaking units 130, so as to heat the blood bag in the shaking unit 130.

[0061] Therefore, due to the provision of the movable connection part 121, it can maintain communication with the exhaust port 154 when it rotates relative to the central column 111, thereby allowing the hot airflow to flow through the exhaust port 154 to the first air guide channel 123, and after flowing to the second air guide channel 124, it is blown towards the shaking unit 130 through the air outlet 125 on the heating body 122.

[0062] When configuring main body 110, please refer to Figures 1-8 In this embodiment, the main body 110 is internally divided into multiple compartments 114. Each compartment 114 is equipped with a mounting frame 115, and each compartment 114 corresponds to a shaking unit 130, with the shaking unit 130 connected to the mounting frame 115 in the corresponding compartment 114. The purpose of this method is to reduce the influence of the heating unit 120 on each compartment 114; that is, when the shaking unit 130 of one compartment 114 is heated, the heating impact on adjacent compartments 114 can be reduced.

[0063] To facilitate the positioning of the heating unit 120 to heat one of the shaking units 130, the top of the main body 110 is provided with a top plate 116. The top plate 116 has multiple through holes 117, each of which corresponds to a chamber 114 to open the shaking unit 130 in the corresponding chamber 114.

[0064] Therefore, when the heating unit 120 heats the shaking unit 130, the heating element 122 of the heating unit 120 can be moved down along the axis of the central column 111 until it matches the corresponding through hole of the shaking unit 130 on the top plate 116, so that the through hole 117 is relatively closed, and the blood bag on the shaking unit 130 in the chamber 114 can be heated.

[0065] In order to facilitate maintaining the position of the heating unit 120 during heating and to play a positioning role when the heating unit 120 rotates around the central column 111, the top plate 116 is provided with a plurality of positioning holes 118, and each through hole 117 has a positioning hole 118 on both sides opposite to it; the heating body 122 is connected to a positioning post 126, which is used to cooperate with the positioning hole 118.

[0066] Further, please refer to Figures 1-8 In this embodiment, when the shaking unit 130 is configured, its function is to shake the blood bag evenly by oscillation. Therefore, the shaking unit 130 includes a movable structure 160 and a shaking disk 127. The movable structure 160 is connected to the mounting frame 115, and the shaking disk 127 is connected to the movable structure 160, and the shaking disk 127 is used to hold the blood bag. The movable structure 160 is used to drive the shaking disk 127 to oscillate in at least one direction. It should be noted that the movable structure 160 may include structures such as a crank-moving assembly or a fan-shaped toothed plate, as described in the prior art; its specific structure will not be elaborated here.

[0067] During the heating process, to allow hot air to escape, the bottom of the chamber 114 is open, and the shaking disc 127 includes a disc body 128 and a mesh plate 129; the disc body 128 is connected to the movable structure 160, and the mesh plate 129 is disposed at the bottom of the disc body 128. That is, after the hot air passes through the blood bag and completes the heat exchange, it can flow out through the mesh plate 129.

[0068] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
