Description

Technical Field

[0001] This utility model relates to the field of intraoperative blood loss monitoring technology, specifically, to a transfusion device for real-time monitoring of intraoperative blood loss. Background Technology

[0002] Real-time monitoring of blood loss during surgery is a core aspect of surgical management, directly impacting patient safety and surgical outcomes. By monitoring blood loss data in real time, issues such as insufficient or excessive blood transfusions can be avoided, enabling goal-oriented transfusions. However, traditional methods of blood loss monitoring typically rely on manual visual estimation, which is subject to subjectivity and error. Especially in cases of significant blood loss or complex surgical scenarios, it is difficult to grasp the dynamics of blood loss in a timely and accurate manner.

[0003] In modern surgery, excessive blood loss can lead to life-threatening situations for patients. Timely blood transfusions can improve the success rate of the surgery. Using real-time blood loss monitoring equipment during transfusions can improve the accuracy of the transfusion amount. When the equipment vibrates due to external factors, it will affect the accuracy of the blood loss data monitoring, which may lead to errors in the amount of blood transfused during the surgery. Utility Model Content

[0004] The purpose of this invention is to provide a transfusion device for real-time monitoring of intraoperative blood loss, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a transfusion device for real-time monitoring of intraoperative blood loss, comprising a device body, a base disposed at the bottom of the device body, a support frame slidably connected to the outer wall of the top of the base, an auxiliary buffer mechanism disposed at the top of the support frame, the auxiliary buffer mechanism being used to buffer the vibration of the device body caused by external factors, the auxiliary buffer mechanism including a support frame fixedly connected to the top of the support frame, a plurality of slide rails symmetrically fixedly connected to the inner side wall of the support frame, a sliding block slidably connected inside each of the slide rails, a limit plate fixedly connected to the end side wall of each of the slide rails, an elastic element fixedly connected between the sliding block and the side wall of the limit plate, a support rod hinged to the side wall of each of the sliding blocks, and the end of each support rod away from the sliding block hinged to the inner side wall of the base.

[0006] By reducing the vibration experienced by the device itself placed on top of the support frame, excessive vibration of the device itself can prevent errors in blood loss monitoring and improve monitoring accuracy.

[0007] As a further improvement to this technical solution, all of the support rods are initially designed to be inclined, and a reinforcing rib is fixedly connected between the side walls of the two support rods near the sliding block. A stabilizing plate is fixedly connected to the inner side wall of the middle of the base, and the stabilizing plate is rectangular.

[0008] By using reinforcing ribs, the supporting force of the support rods is increased, enabling multiple support rods to exert force simultaneously and improving stability.

[0009] As a further improvement to this technical solution, two side plates are symmetrically fixedly connected to the top of both ends of the support frame. Threaded rods are threadedly connected to the inner walls of both side plates, and clamping plates are provided at the ends of both threaded rods. Two legs are symmetrically fixedly connected to the bottom of the device body, and the two legs are respectively located between the two side plates and the two clamping plates.

[0010] By continuously rotating the threaded rod, the clamping plate is pulled closer to one side of the side plate, ultimately achieving the purpose of clamping and fixing the support leg, ensuring that the equipment body remains stable while operating above the top of the support frame.

[0011] As a further improvement to this technical solution, the side plate is symmetrically and fixedly connected to two guide rods on the outer wall of one side of the clamping plate. The clamping plate is slidably connected to the two guide rods, and the clamping plate is rotatably connected to the end of the threaded rod. Limit blocks are fixedly connected to the ends of the two guide rods away from the side plate.

[0012] When the clamping plate slides on the outer wall of the two guide rods, it limits the movement of the clamping plate, allowing it to move only in the horizontal direction. The limiting block limits the movement of the clamping plate on the outer wall of the guide rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this intraoperative real-time blood loss monitoring transfusion device, an auxiliary buffer mechanism is set up so that when the elastic element is compressed and resets, multiple support rods lift the support frame again. This reduces the vibration effect on the device body placed on top of the support frame, avoids large vibrations of the device body that could cause errors in blood loss monitoring, and improves monitoring accuracy.

[0023] Example 1

[0024] Please see Figures 1-4As shown, this embodiment provides a transfusion device for real-time monitoring of intraoperative blood loss, including a device body 1. A base 2 is provided at the bottom of the device body 1. A support frame 3 is slidably connected to the outer wall of the top of the base 2. An auxiliary buffer mechanism 4 is provided at the top of the support frame 3. The auxiliary buffer mechanism 4 is used to buffer the vibration of the device body 1 caused by external factors. The auxiliary buffer mechanism 4 includes a support frame 41 fixedly connected to the top of the support frame 3. Several slide rails 12 are symmetrically fixedly connected to the inner side wall of the support frame 41. Sliding blocks 42 are slidably connected inside each slide rail 12. Limiting plates 43 are fixedly connected to the side walls of each slide rail 12. Elastic members 44 are fixedly connected between the sliding blocks 42 and the side walls of the limiting plates 43. Support rods 45 are hinged to the side walls of each sliding block 42. The ends of the support rods 45 away from the sliding blocks 42 are hinged to the inner side wall of the base 2. Vibrations caused by external factors during use can affect the accuracy of blood loss monitoring of the device body 1. When the device body 1 vibrates, the support frame 41 is pressed down, causing the support frame 41 and the support bracket 3 to slide downward on the outer wall of the top of the base 2. During this process, the highest point of the support rod 45 will flip towards the side of the base 2, causing the support rod 45 to push the sliding block 42 to slide towards the side of the limiting plate 43 inside the slide rail 12. At the same time, it will squeeze the elastic element 44, which is composed of a spring, a limiting element, and a shell. After the spring is squeezed, it will reset, causing the multiple support rods 45 to lift the support frame 41 again. The above process is repeated, which reduces the vibration effect on the device body 1 placed on top of the support frame 41, avoids errors in blood loss monitoring caused by large vibrations of the device body 1, and improves the monitoring accuracy.

[0025] In its initial state, all support rods 45 are designed with an inclination. A reinforcing rib 51 is fixedly connected between the side walls of two support rods 45 near the sliding block 42. The reinforcing rib 51 increases the supporting force of the support rods 45, allowing multiple support rods 45 to exert force synchronously and improving stability. Two side plates 61 are symmetrically fixedly connected to the top of both ends of the support frame 41. Threaded rods 62 are threadedly connected to the inner walls of both side plates 61. Clamping plates 63 are provided at the ends of both threaded rods 62. Two legs 11 are symmetrically fixedly connected to the bottom of the equipment body 1. The two legs 11 are located between the two side plates 61 and the two clamping plates 63, respectively. By continuously rotating the threaded rods 62, the threaded rods 62 move synchronously with the clamping plates 63. When the clamping plates 63 move closer to the side plates 61, they can clamp and fix the legs 11 located between them. When the clamping plates 63 move away from the side plates 61, the legs 11 are not subject to over-clamping, making it easier for workers to move the equipment body 1 away, achieving the purpose of quick installation and disassembly, and improving the flexibility of use.

[0026] Two guide rods 71 ​​are symmetrically fixedly connected to the outer wall of the side plate 61 on one side of the clamping plate 63. The clamping plate 63 is slidably connected to the two guide rods 71. When the clamping plate 63 slides on the outer wall of the two guide rods 71, it limits the movement of the clamping plate 63, so that the clamping plate 63 can only move in the horizontal direction. The clamping plate 63 is rotatably connected to the end of the threaded rod 62. When the support leg 11 is stably placed between the side plate 61 and the clamping plate 63, by continuously rotating the threaded rod 62, the threaded rod 62 moves the clamping plate 63 toward the side plate 61. 1. Pulling it closer from one side ultimately achieves the purpose of clamping and fixing the support leg 11, ensuring that the equipment body 1 remains stable during operation above the top of the support frame 41. The ends of the two guide rods 71 ​​away from the side plate 61 are fixedly connected to limit blocks 72. The limit blocks 72 are used to limit the movement of the clamping plate 63 on the outer wall of the guide rods 71. A stabilizing plate 8 is fixedly connected to the inner side wall in the middle of the base 2. The stabilizing plate 8 is rectangular. The rectangular stabilizing plate 8 increases the contact area between the base 2 and the flat surface, which can improve stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
