Description

Technical Field

[0001] This utility model relates to medical weighing equipment, and more particularly to a blood pad blood volume counting and counting device. Background Technology

[0002] In obstetric surgery, the amount of bleeding in the mother is relatively large. Dressings are usually used to absorb the blood during the operation. Measuring and recording the amount of bleeding during the operation is of great significance for assessing the mother's condition, timely handling of intraoperative complications, and postoperative recovery.

[0003] Weighing is one of the clinical methods for measuring blood loss. This method calculates the blood loss by weighing the dressings used in surgery and measuring the difference between their wet and dry weights (net weight). However, due to the large number of dressings used in surgery, electronic scales cannot automatically record the quantity during weighing, and therefore cannot automatically obtain the dry weight of all dressings. Consequently, it is impossible to weigh all dressings at once to obtain the total blood loss. Therefore, medical staff must either manually count the dressings and enter the data into the electronic scale, or obtain only the total wet weight and then manually subtract the dry weight. This weighing process is cumbersome and reduces the efficiency of blood loss measurement. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide a blood pad blood volume counting and measurement device.

[0005] To achieve the above objectives, according to an embodiment of the present invention, a blood pad blood volume counting and statistic device includes an electronic tag on the carrying strap of each blood pad, and the blood pad blood volume counting and statistic device comprises:

[0012] According to one embodiment of the present invention, the support extends in the front-to-back direction, and the length of the support is not less than the length of the carrier plate.

[0013] According to one embodiment of the present invention, a pressure arm is provided on one side of the support platform, and the pressure arm is pivotable between an open position and a closed position;

[0014] When the pressure arm is in the open position, the pressure arm is located outside the support platform. When the pressure arm is in the closed position, the pressure arm is pressed against the top surface of the support platform to press the lifting straps of each blood pad tightly against the top surface of the support platform.

[0015] According to one embodiment of the present invention, an elastic element is provided between the pressure arm and the support platform, and the elastic force provided by the elastic element forces the pressure arm to be in the pressing position.

[0016] According to one embodiment of the present invention, the pressure arm includes:

[0017] Pressing strip;

[0018] Two L-shaped support legs are located at both ends of the pressure strip. One end of each L-shaped support leg is fixedly connected to the pressure strip, and the other end of each L-shaped support leg is pivotally connected to the outer side of the support platform.

[0019] When the pressure arm is in the pressing position, the pressure strip is pressed against the top surface of the support and extends along the length of the support.

[0020] According to one embodiment of the present utility model, the outer side of the support platform is provided with two pivot seats, and the two pivot seats correspond one-to-one with the two L-shaped legs. The other end of each L-shaped leg is pivotally connected to the pivot seat through a pivot pin.

[0021] The elastic element is a torsion spring, which passes through the pivot pin, with one end of the torsion spring abutting against the pivot seat and the other end of the torsion spring abutting against the L-shaped support leg.

[0055] The following describes in detail, with reference to the accompanying drawings, the blood pad blood volume statistics and counting device of this utility model embodiment.

[0056] Reference Figures 1 to 6As shown, the blood volume counting and counting device for blood pads 30 provided according to the embodiments of the present invention has an electronic tag 302 on the carrying strap 301 of each blood pad 30, and the blood volume counting and counting device for blood pads 30 includes an electronic scale 10 and a carrier plate 20.

[0057] Specifically, the electronic scale 10 includes a housing 101, a weighing platform 102, and a display platform 103. The weighing platform 102 is located on the top surface of the housing 101 and at the rear of the housing 101; the display platform 103 is located on the top surface of the housing 101 and at the front of the housing 101. This front-to-back arrangement of the weighing platform 102 at the rear of the top surface of the housing 101 and the display platform 103 at the front facilitates the operator's observation of the displayed data while weighing. The weighing platform 102 supports the carrier tray 20 and the blood pads 30 therein, enabling accurate measurement of their weight. The display platform 103 can be a digital display screen, capable of simultaneously displaying the number of blood pads 30 and the total blood content data.

[0058] The carrier tray 20 is adapted to be placed on the weighing platform 102 for storing used blood pads 30. The carrier tray 20 is designed to fit the shape and size of the weighing platform 102, and its main function is to store used blood pads 30. The carrier tray 20 may be made of a lightweight and easy-to-clean material, such as stainless steel.

[0059] The electronic scale 10 also includes a support platform 104 for holding the carrying strap 301 of the blood pad 30, and the support platform 104 is provided with a tag reader 105 for reading the electronic tag 302; the display platform 103 is configured to display the total blood content of the blood pad 30 and the number of blood pads 30.

[0060] As described above, an electronic tag 302 is attached to the carrying strap 301 of each blood pad 30. This electronic tag 302 is an RFID (Radio Frequency Identification) tag, specifically a passive RFID tag. The advantages of choosing a passive RFID tag are: small size, low cost, no battery required, long lifespan, and ability to meet the distance requirements for identification of the blood pad 30. Each RFID tag has a unique identification code, which can be used to accurately identify each blood pad 30.

[0061] Correspondingly, a support platform 104 for holding the blood pad 30 carrying strap 301 is provided on the electronic scale 10, and a tag reader 105 is installed on the support platform 104. When the carrying strap 301 of the blood pad 30 is placed on the support platform 104, the reader can automatically identify and read the information of the electronic tag 302, thereby realizing the automatic counting function of the blood pad 30.

[0062] In actual use, medical staff only need to place the used blood pads 30 into the tray 20 and place their carrying straps 301 on the support table 104. The electronic scale 10 will then automatically count and weigh the blood. The system will automatically calculate the blood content (by subtracting the dry weight from the wet weight) and update the number of blood pads 30 and the total blood content in real time on the display panel 103. This design greatly simplifies the blood volume statistics process during surgery and improves work efficiency.

[0063] According to the blood pad 30 blood volume counting and counting device provided in this embodiment of the utility model, the device identifies and counts the number of blood pads 30 by setting an electronic tag 302 on the carrying strap 301 of each blood pad 30 and equipping a reader on the platform 104 of the electronic scale 10. Simultaneously, it uses a tray 20 to collect and weigh used blood pads 30, thus automatically completing the dual functions of counting blood pads 30 and measuring blood volume. This design overcomes the cumbersome problems of manual counting and calculation required in traditional weighing methods, improving the efficiency and accuracy of blood volume measurement during surgery. The display panel 103 can intuitively display the total number of blood pads 30 and the total blood volume, enabling medical staff to monitor the bleeding situation during surgery in real time and providing timely and reliable data support for clinical decision-making.

[0064] In one embodiment of this utility model, the total blood content of the blood pad 30 = total wet weight - number of blood pads 30 * dry weight of each blood pad 30, and the number of blood pads 30 = number of electronic tags 302.

[0065] This embodiment uses the following calculation method to obtain the total blood content of the blood pads 30. Specifically, the formula for calculating the total blood content is: Total blood content = Total wet weight - Number of blood pads 30 * Dry weight of each blood pad 30. The number of blood pads 30 is automatically obtained by counting the number of electronic tags 302, i.e., Number of blood pads 30 = Number of electronic tags 302.

[0066] In actual operation, after the used blood pads 30 are placed on the carrier tray 20, the weighing platform 102 automatically measures the total wet weight. Simultaneously, the label reader 105 on the tray 104 reads the electronic tags 302 on the carrying strap 301, and the system automatically counts the number of tags to obtain the accurate number of blood pads 30. Since the dry weight of each blood pad 30 is a fixed, known value that can be pre-stored in the system, the system can automatically calculate the total blood content according to the above formula. This calculation method requires no manual intervention, avoiding errors that may arise from manual calculation.

[0067] For example, assuming the weighing platform 102 measures a total wet weight of 500 grams, and the RFID reader identifies 5 electronic tags 302 (i.e., 5 blood pads 30), with each blood pad 30 having a dry weight of 20 grams, the system will automatically calculate: Total blood content = 500 grams - (5 * 20 grams) = 400 grams. This calculation process is real-time; as new blood pads 30 are placed on the carrier tray 20, the system will update the calculation result immediately.

[0068] The automated data collection and calculation process completely eliminates manual counting and calculation, greatly improving the efficiency and accuracy of blood volume statistics during surgery. At the same time, this method avoids the tedious operation of weighing each blood pad individually, as required by traditional methods, allowing medical staff to focus more on the surgery itself and improving the overall efficiency of medical work.

[0069] Preferably, the support platform 104 extends in the front-to-back direction, and the length of the support platform 104 is not less than the length of the carrier tray 20. This design ensures that the support platform 104 can completely cover the longitudinal range of the carrier tray 20, providing ample space for the placement of the blood pad 30 carrying strap 301. When the length of the support platform 104 is equal to or slightly larger than the length of the carrier tray 20, it ensures that no matter where the blood pad 30 is placed on the carrier tray 20, its carrying strap 301 can be easily placed on the corresponding support platform 104. This one-to-one spatial relationship allows medical personnel to intuitively associate the positions of the blood pad 30 and its carrying strap 301, avoiding operational confusion. In practical applications, when medical personnel place the blood pad 30 into the carrier tray 20, they can naturally place the corresponding carrying strap 301 on the support platform 104 directly above it. The extension direction of the support platform 104 is parallel to the carrier tray 20; this layout ensures operational continuity and avoids tangling or confusion between the carrying straps 301. In addition, the ample length of the support 104 provides sufficient recognition space for the tag reader 105, ensuring that the information of each electronic tag 302 can be accurately read.

[0070] Reference Figures 1 to 2 and Figures 4 to 5 As shown, in some embodiments of this utility model, a pressure arm 106 is provided on one side of the support 104, and the pressure arm 106 can pivot between the open position and the closed position.

[0071] When the pressure arm 106 is in the open position, the pressure arm 106 is located outside the support table 104, providing sufficient operating space for medical personnel to place the blood pads 30 and the carrying straps 301; when the pressure arm 106 is in the closed position, the pressure arm 106 is pressed against the top surface of the support table 104 to press the carrying straps 301 of each blood pad 30 tightly against the top surface of the support table 104.

[0072] When a new blood pad 30 carrying strap 301 needs to be placed, the medical staff first rotates the pressure arm 106 to the open position. At this time, the pressure arm 106 is located outside the support table 104 and will not interfere with the placement of the carrying strap 301. The medical staff can then lay the carrying strap 301 of the blood pad 30 flat on the top surface of the support table 104. After placement, the pressure arm 106 is rotated to the closed position, where it evenly presses down on all the carrying straps 301, ensuring they are firmly against the surface of the support table 104. This closed position ensures that the carrying straps 301 remain in a stable position.

[0073] In this embodiment, a pressure arm 106 is provided on the support platform 104. On the one hand, the pressure arm 106 fixes the blood pad 30 and ensures that the carrying strap 301 remains within the recognition range of the label reader 105, thereby improving the accuracy and reliability of label recognition. On the other hand, the presence of the pressure arm 106 prevents the carrying strap 301 from shifting or falling off during operation, avoiding the risk of double counting or omission. Furthermore, the carrying strap 301 in the pressed state is neatly arranged, making it easy for medical staff to visually align the positions of the blood pad 30 and the carrying strap 301, which is beneficial for weighing operations.

[0074] Reference Figure 3 As shown, in one embodiment of this utility model, an elastic element 107 is provided between the pressure arm 106 and the support 104. The elastic force provided by the elastic element 107 forces the pressure arm 106 to remain in the pressed position. This elastic element 107 can be a torsion spring, a tension spring, or other suitable elastic element. Its installation position is usually set at the pivot point of the pressure arm 106 or at the connection point between the pressure arm 106 and the support 104 to ensure that the direction of the elastic force can effectively push the pressure arm 106 to the pressed position.

[0075] In practical use, when medical staff need to place or adjust the blood pad 30 lifting strap 301, they only need to lift the pressure arm 106 upwards by hand to overcome the elastic force of the elastic element 107 and open the pressure arm 106. Once the operation is completed, after releasing the pressure arm 106, the elastic force of the elastic element 107 will automatically return the pressure arm 106 to the pressed position, without requiring medical staff to perform any additional pressing action. This automatic return feature is particularly suitable for the rapid operation needs in the surgical environment, allowing medical staff to focus on placing the blood pad 30 without worrying about the fixation of the pressure arm 106.

[0076] This embodiment achieves the automatic reset function of the pressure arm 106 by setting the elastic element 107, which simplifies the operation process and improves the ease of use; in addition, the continuous and stable pressure provided by the elastic element 107 ensures that the blood pad 30 lifting strap 301 is always in the identification position, which improves the reliability of RFID identification.

[0077] Reference Figures 1 to 2As shown, in one embodiment of the present invention, the pressure arm 106 includes a pressure strip 106a and two L-shaped legs 106b. The two L-shaped legs 106b are respectively located at both ends of the pressure strip 106a. One end of each L-shaped leg 106b is fixedly connected to the pressure strip 106a, and the other end of each L-shaped leg 106b is pivotally connected to the outer side of the support platform 104.

[0078] When the pressure arm 106 is in the pressing position, the pressure strip 106a presses against the top surface of the support 104 and extends along the length direction of the support 104.

[0079] In this embodiment, the vertical portion of the L-shaped support leg 106b provides the height space required for the opening and closing of the pressure arm 106, while the horizontal portion is used for pivotal connection with the support platform 104. This L-shaped structure allows the pressure arm 106 to obtain sufficient lifting height when opened, facilitating operation by medical personnel; at the same time, it ensures that the pressure strip 106a is completely in contact with the top surface of the support platform 104 when pressed. The symmetrical arrangement of the two L-shaped support legs 106b not only ensures the stability of the structure but also allows the pressure strip 106a to apply pressure evenly.

[0080] When in the pressed position, the pressure arm 106 extends parallel to the length of the support 104 and fits tightly against the top surface of the support 104. This parallel arrangement ensures that the pressure strip 106a can apply uniform pressure to the blood pad 30 lifting strap 301 along the entire length of the support 104. The length of the pressure strip 106a is designed to match the length of the support 104, covering all possible placements of the blood pad 30 lifting strap 301.

[0081] The pressure arm 106, consisting of a pressure strip 106a and an L-shaped support leg 106b, achieves smooth movement and precise positioning during the opening and closing process, thus improving the reliability of the device. The arrangement of the L-shaped support leg 106b ensures that the pressure strip 106a can apply uniform and stable pressure to the lifting strap 301 of the blood pad 30, thereby improving the accuracy of RFID identification.

[0082] Reference Figures 1 to 3 As shown, in one embodiment of this utility model, the outer side of the support 104 is provided with two pivot seats 1041, and the two pivot seats 1041 correspond one-to-one with the two L-shaped legs 106b. The other end of each L-shaped leg 106b is pivotally connected to the pivot seat 1041 through a pivot pin 108. This connection method enables the pressure arm 106 to perform stable and precise opening and closing movements.

[0083] The elastic element 107 is a torsion spring, which passes through the pivot pin 108. One end of the torsion spring abuts against the pivot seat 1041, and the other end abuts against the L-shaped support leg 106b. This installation method allows the torsion spring to generate a continuous torsional torque during the opening and closing of the pressure arm 106. When medical personnel lift the pressure arm 106, the torsion spring is compressed and stores elastic potential energy; after releasing the pressure arm 106, the torsion spring releases the potential energy and automatically returns the pressure arm 106 to the pressed position.

[0084] The engagement of the pivot seat 1041 and the pivot pin 108 provides stable motion support for the pressure arm 106. A torsion spring enables the pressure arm 106 to automatically reset. The overall structure is compact and rationally designed, easy to assemble, and ensures the long-term reliable rotation of the pressure arm 106, thereby guaranteeing the accuracy of RFID tag identification and the convenience of equipment use.

[0085] Reference Figure 2 As shown, in one embodiment of the present invention, the bottom of the carrier plate 20 is provided with a positioning protrusion, and the weighing platform 102 is provided with a positioning groove H102 that cooperates with the positioning protrusion.

[0086] The structure of the protrusion and groove H102 enables the rapid and accurate positioning of the carrier plate 20, preventing positional deviation or slippage from the weighing platform 102 during use, ensuring reliability during use, reducing the risk of contamination, and improving the convenience of use for medical staff.
