Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blood donation equipment in blood stations, and specifically relates to a blood bag stopper breaking device. Background Art
[0002] In the blood collection and supply industry, the blood collection bag adapted by this device is a blood collection bag with a disposable bypass sampling device, which usually includes a blood collection needle, a blood collection tube, a three-way stopcock, a bypass sampling device, a blood transfusion socket, a clip, a transfer tube, a blood collection bag, anticoagulant, etc. There is a breakable stopper on one side of the three-way stopcock connected to the blood collection bag. The breakable stopper can isolate the blood collection bag and blood before the sampling is completed. However, during blood collection, medical staff need to manually or with the help of tools to break the breakable stopper to connect the blood bag and the hose. The traditional manual stopper breaking method has problems such as inconvenient operation, low efficiency, and easy to cause pollution or injury. Medical staff need to manually forcefully break the breakable stopper. This process is not only time-consuming and laborious, but also may cause blood pollution due to improper operation. Content of the Utility Model
[0003] One technical problem to be solved by this application is: to provide a device that can automatically, stably and safely complete the opening action of the blood bag stopper breaking three-way stopcock to meet the requirements of the medical field for efficient and safe blood transfusion and blood processing.
[0004] To solve the above technical problem, an embodiment of this application provides a blood bag stopper breaking device, which includes a base, and also includes a stopper breaking member. The stopper breaking member is arranged on the base, and a groove is also arranged on the base. The blood bag stopper breaking three-way stopcock is placed in the groove and passes through the stopper breaking member, and the stopper breaking three-way stopcock is conducted by the automatic action of the stopper breaking member.
[0005] And anti-detachment structures are arranged on both the groove and the stopper breaking member, and the anti-detachment structures are used for anti-detachment protection when the blood bag stopper breaking three-way stopcock is broken.
[0006] In some embodiments, the stopper breaking member includes a servo motor arranged on the base, and a rotating rocker arm is arranged at the output end of the servo motor. The end of the rotating rocker arm is U-shaped, and the opening direction of the U-shaped is the same as the orientation of the groove on the base.
[0007] In some embodiments, the servo motor is a stepper motor.
[0008] In some embodiments, the diameter of the opening of the U-shaped end of the rotating rocker arm and the diameter of the groove are both larger than the diameter of the stopper breaking three-way stopcock.
[0009] In some embodiments, the anti-detachment structure includes arc-shaped grooves respectively opened on the inner wall of the groove and the inner side of the opening at the end of the rotating rocker arm.
[0010] The utility model has at least the following beneficial effects:
[0011] Different from the existing technology, it cleverly combines automation and mechanical design. Through a precise base platform and a high-efficiency plug-opening system, it realizes the intelligent and automated operation of the blood bag plug-opening tee (multi-way valve). The core is to use a servo (especially a high-precision stepper motor) as a power source to drive a special rotating rocker arm for precise movements. The U-shaped design of the rocker arm perfectly fits the groove structure, ensuring that the blood bag tee can be placed in it accurately and quickly turned on under automated control.
[0012] In addition, this device also innovatively introduces an anti-drop structure. This design detail is equipped with fine arc-edge grooves on the inner wall of the groove and the end of the rotating rocker arm, which doubles the protection of the blood bag tee to ensure that it is stable and will not fall off during the plug-breaking process, greatly improving the safety and stability of the operation.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figures 1-4 The utility model provides a technical solution: an efficient and safe blood bag deblocking device, which is specially designed for the medical field and aims to simplify the conduction process of the blood bag deblocking tee, while ensuring stability and sterility during operation. The device is mainly composed of a base 1, a deblocking piece 2 and a series of precision components, which work together to realize automated deblocking operation.
[0020] Base 1: As the support platform of the entire device, Base 1 is made of a sturdy and durable material to ensure stability during long-term use. Its surface is specially treated to be both anti-slip and easy to clean, meeting the strict requirements of the medical environment. The carefully designed groove 3 on Base 1 has a shape that perfectly matches the blood bag plug-breaking tee 4, providing a reliable foundation for the accurate placement of the tee.
[0021] Plug-breaking part 2: As the core component, through precise mechanical structure design, it realizes the automatic conduction of the blood bag plug-breaking tee. An internal high-performance stepper motor is used as the servo 6 in Plug-breaking part 2. This motor is characterized by high precision, low noise, and easy control. The specific code during use is as follows:
[0022] #include<reg52.h> / / Use 8051 series single-chip microcomputer
[0023] #define MOTOR_STEP_PIN P2_0 / / The control pin of the stepper motor is connected to P2.0
[0024]
[0025]
[0026] It ensures the accuracy and repeatability of the plug-breaking action. The output end of the servo 6 is connected to the rotating rocker arm 7. This rocker arm is carefully designed and optimized. The end part is designed in a U shape, and the orientation of the U-shaped opening is the same as that of the groove 3, ensuring effective contact with the tee and smooth plug-breaking.
[0027] Rotating rocker arm 7: As the component directly acting on the blood bag plug-breaking tee, the material of the rotating rocker arm 7 is selected as a high-strength and wear-resistant alloy material to ensure the stability and durability during long-term use. The caliber size of its U-shaped opening is precisely calculated, which can not only accommodate tees of different specifications but also provide sufficient gripping force and stability during the plug-breaking process. At the same time, the movement trajectory of the rotating rocker arm 7 is optimized to ensure the smoothness and non-impact of the plug-breaking action, thus protecting the tee and the blood bag from damage.
[0028] Anti-detachment structure 5: To further improve the safety and reliability of the device, anti-detachment structures 5 are set on the inner wall of the groove 3 and the inner side of the U-shaped opening of the rotating rocker arm 7. These anti-detachment structures 5 are mainly composed of arc-edge grooves 8, and the design inspiration comes from the locking principle in nature. They can provide additional gripping force and stability during the plug-breaking process, effectively preventing the tee from accidentally detaching during the plug-breaking process. This anti-detachment design not only improves the success rate of the operation but also greatly reduces the risk of medical accidents caused by improper operation.
[0029] In summary, this blood bag stopper-breaking device realizes the rapid, accurate and safe conduction of the three-way joint 4 of the blood bag stopper through the integration of automation technology and precision mechanical design. Its efficient operation process, stable performance and reliable safety features give it broad application prospects and important practical value in the medical field.
