Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a blood rewarming device for an autologous blood recovery equipment. Background Technology

[0002] With the continuous advancement of surgical techniques, the clinical demand for blood is increasing, making blood resources more precious and often resulting in a supply shortage. Traditional allogeneic blood transfusions not only suppress the patient's immune function and increase the risk of postoperative wound infection, but also hinder wound healing and may lead to the spread of infectious diseases such as hepatitis and HIV / AIDS. Therefore, in recent years, the application of autologous blood transfusion in surgery has gradually increased and has gained widespread attention and acceptance. However, in this process, the recovered blood needs to undergo separation and processing to ensure that it meets the reinfusion standards.

[0003] Furthermore, blood needs to be kept at a low temperature during preservation to maintain red blood cells in a low metabolic state, thus ensuring their normal oxygen-carrying capacity outside the body. However, during surgical procedures, when large amounts of refrigerated blood need to be transfused rapidly, the infusion of large quantities of cold blood may cause a drop in the patient's body temperature, leading to coagulation disorders, decreased blood pressure, and peripheral circulatory disturbances. In severe cases, it can even cause cardiac arrest and may trigger febrile non-hemolytic transfusion reactions. Therefore, modern surgical practice has gradually reduced the direct transfusion of refrigerated blood and blood products into patients, replacing it with a standard procedure of rewarming the blood before transfusion.

[0004] Currently, the common method for warming blood involves rewarming the blood bag itself until it reaches a suitable temperature before transfusing the blood into the patient using a transfusion set. However, because the transfusion tubing is exposed, the heated blood is easily affected by the ambient temperature during transfusion and gradually cools down, resulting in a loss of warming effect. Existing blood warmers often cannot maintain the blood temperature continuously throughout the entire transfusion process until the blood is completely delivered to the patient; therefore, their heating effect is not stable enough, and their practicality is relatively low.

[0005] In view of the above-mentioned technical defects, a blood rewarming device for autologous blood recovery equipment is proposed to solve the problems existing in the prior art. Utility Model Content

[0006] In order to overcome the shortcomings of existing blood rewarming devices, which cannot continuously keep the warmed blood warm during blood transfusion and have poor practicality, the purpose of this utility model is to provide a blood rewarming device for autologous blood recovery equipment.

[0007] Technical Solution: A blood rewarming device for autologous blood recovery equipment includes an autologous blood recovery machine body, a control panel, a control host, a support block, a first support rod, a suspension assembly, a suspension buckle, a flexible sleeve, an ultrasonic sensor, a temperature sensor, a connecting block, and a heating wire. The control panel is mounted on the front of the autologous blood recovery machine body and is electrically connected to it. The first support rod is connected to the top of the autologous blood recovery machine body, and a support block is slidably connected to the lower side of the first support rod. The control host is mounted on the support block. A suspension assembly is mounted on the upper side of the first support rod, and a suspension buckle is slidably connected to the upper side of the first support rod. A connecting block is snapped onto the suspension buckle, and a flexible sleeve is connected to the connecting block. An ultrasonic sensor is mounted on the connecting block, a heating wire is installed inside the flexible sleeve, and a temperature sensor is installed on the lower side of the flexible sleeve. The autologous blood recovery machine body, ultrasonic sensor, temperature sensor, and heating wire are all electrically connected to the control host.

[0008] As an improvement to the above solution, the control host has a touch screen display, and the control host is connected to the flexible sleeve via a line to control the heating and receive temperature feedback.

[0009] As an improvement to the above solution, the suspension assembly includes a second support rod, a second threaded rod, and hooks. The second support rod is slidably connected to the first support rod, and the second threaded rod is threadedly connected to the upper left side of the first support rod. The second threaded rod abuts against the second support rod, and multiple hooks for suspending blood bags are evenly threaded along the upper side of the second support rod.

[0010] As an improvement to the above solution, it also includes a first threaded rod and a third threaded block. The first threaded rod is threadedly connected to the support block, and the first threaded rod abuts against the first support rod. The third threaded block is threadedly connected to the left side of the suspension buckle, and the third threaded block abuts against the first support rod.

[0011] As an improvement to the above solution, it also includes casters; four casters are evenly connected to the bottom of the autologous blood recovery machine.

[0012] Beneficial effects: 1. When warmed blood is transfused through the transfusion set, the blood flows through a built-in ultrasonic sensor. Simultaneously, the heating wire activates and heats the flexible tubing, ensuring the blood remains within a suitable temperature range throughout the transfusion process and effectively preventing heat loss.

[0013] 2. A temperature sensor is installed on the flexible cannula. When blood flows through it, the temperature sensor can monitor the blood temperature in real time and transmit the data to the control host. The control host determines whether the temperature of the blood entering the patient is appropriate based on the received information. If an abnormal blood temperature is detected, the control host will immediately issue a prompt message to remind medical staff to take appropriate measures. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: A blood rewarming device for an autologous blood recovery system, such as... Figures 1-4As shown, the device includes an autologous blood recovery machine body 1, casters 10, a control panel 11, a control host 2, a support block 21, a first support rod 3, a suspension assembly, a suspension buckle 6, a flexible sleeve 7, an ultrasonic sensor 70, a temperature sensor 71, a connecting block 72, and a heating wire 73. Four casters 10 are evenly rotatably connected to the bottom of the autologous blood recovery machine body 1 to assist in the movement of the rewarming device. The control panel 11 is installed on the front side of the autologous blood recovery machine body 1, and the body is electrically connected to the control panel 11. The first support rod 3 is connected to the top of the body, and the support block 21 is slidably connected to the lower side of the first support rod 3. The control host 2 is bolted to the support block 21. A suspension assembly is installed on the side. A suspension buckle 6 is slidably connected to the upper side of the first support rod 3. A connecting block 72 is snapped onto the suspension buckle 6. A flexible sleeve 7 is connected to the connecting block 72. The flexible sleeve 7 is open to facilitate the fixation of the blood transfusion tubing. An ultrasonic sensor 70 for detecting the presence of blood is installed on the connecting block 72 by bolts. A heating wire 73 for heating blood is installed inside the flexible sleeve 7. A temperature sensor 71 for detecting blood temperature is installed on the lower side of the flexible sleeve 7. The autologous blood recovery machine body 1, the ultrasonic sensor 70, the temperature sensor 71, and the heating wire 73 are all electrically connected to the control host 2. The control host 2 has a touch screen display. The control host 2 is connected to the flexible sleeve 7 through a circuit and controls the heating and receives temperature feedback.

[0021] like Figures 1-2 As shown, the suspension assembly includes a second support rod 4, a second threaded rod 40, and hooks 5. The second support rod 4 is slidably connected to the first support rod 3. The second threaded rod 40 is threadedly connected to the upper left side of the first support rod 3. The second threaded rod 40 abuts against the second support rod 4. Multiple hooks 5 for suspending blood bags are evenly threaded around the upper side of the second support rod 4.

[0022] like Figure 2 As shown, it also includes a first threaded rod 22 and a third threaded block 60. The first threaded rod 22 is threadedly connected to the support block 21. The first threaded rod 22 abuts against the first support rod 3 to fix the support block 21 and the control host 2. The third threaded block 60 is threadedly connected to the left side of the suspension buckle 6. The third threaded block 60 abuts against the first support rod 3 to fix the suspension buckle 6.

[0023] The autologous blood recovery machine body 1 is used to collect, process, and re-transfuse the patient's own blood during surgery. The various functions of the autologous blood recovery machine can be controlled via the control panel 11. During surgery, when rewarmed blood needs to be transfused, the blood bag is first suspended on the hook 5, and the transfusion set is inserted. The height of the hook 5 can be adjusted according to actual needs. Specifically, the second threaded rod 40 can be loosened to de-fix the second support rod 4, and then the position of the second support rod 4 can be adjusted upwards or downwards to adjust the height of the hook 5. After the blood bag is suspended, the flexible sheath 7 is manually pulled open, and the transfusion tubing is inserted into the flexible sheath 7.

[0024] Next, the blood heating button is pressed on the control unit 2, and the switch on the transfusion set is adjusted. When blood enters the flexible sheath 7 through the transfusion tubing, it flows past the ultrasonic sensor 70. At this time, the control unit 2 triggers the heating wire 73 inside the flexible sheath 7 to heat up, causing the flexible sheath 7 to warm up. As the blood flows past the temperature sensor 71, the temperature sensor 71 transmits the blood temperature to the control unit 2 in real time. The control unit 2 uses a built-in algorithm to determine whether the temperature of the blood input to the human body is appropriate. If the blood temperature is abnormal, the control unit 2 will issue a prompt message to remind medical staff to pay attention.

[0025] During use, the height of the flexible sleeve 7 can be adjusted according to actual needs. Specifically, loosen the third threaded block 60 so that it no longer secures the suspension buckle 6, then move the suspension buckle 6 up or down to adjust the height of the flexible sleeve 7. After adjustment, tighten the third threaded block 60 so that it abuts against the first support rod 3 to ensure a fixed position. After use, the connecting block 72 can be removed from the suspension buckle 6 for maintenance of the internal components of the flexible sleeve 7.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
