Abstract
Description
Technical Field
[0001] The utility model relates to daily necessities for human beings, in particular to medical equipment, and more particularly to an air bag fixing device for assisting puncture. Background Art
[0002] In medicine, peripherally inserted central catheters (PICCs) have become a common method for long-term intravenous drug delivery. During PICC insertion, the vein must be precisely located and punctured, which typically requires the operator to stretch the patient's skin to stabilize the vessel and improve the success rate of the puncture. However, in practice, the operator is already sterile and their hands must remain sterile, making it impossible to perform the auxiliary skin stretching procedure simultaneously.
[0003] Conventional medical tape or elastic bandages are used to help secure the puncture site, but these methods have limitations. While simple and easy to use, they lack the ability to precisely control skin tension and cannot be quickly adjusted, which impacts puncture efficiency. Furthermore, the use of tape or bandages can cause additional pressure or damage to the patient's skin, limiting their applicability, especially for patients with sensitive skin or special conditions. Finally, the effectiveness of these methods is affected by various factors, such as the patient's body shape and skin elasticity. Their adaptability and flexibility are limited, making it difficult to guarantee the stability and success rate of each puncture. Summary of the Invention
[0004] The purpose of the utility model is to provide a puncture-assisting airbag fixing device, which aims to solve the technical problem in the prior art that the tension of the puncture site cannot be quickly and accurately controlled.
[0005] The cam is fixed on the upper part of the U-shaped fixing base, and the cam is fixed on the lower part of the U-shaped fixing base.
[0006] Furthermore, a handle is provided on the support seat.
[0007] Furthermore, a remote control bracket is installed on the height-adjustable bracket.
[0008] Compared with the existing technology, the effect of the present invention is positive and obvious. The present invention is used to assist the peripherally inserted central venous catheter (PICC) process. The inflation and deflation of multiple airbags are used to adjust the patient's arm support and the degree of skin tightening, thereby achieving a firm fixation of the puncture site and precise adjustment of the skin tension. The height of the support seat is adjusted by a height-adjustable bracket, the position of the base is adjusted by a roller, and the height of the upper airbag is adjusted by a telescopic rod, thereby adjusting the height of the patient's arm and the direction in which the skin needs to be tightened. This not only improves the patient's comfort and safety, but is also suitable for patients of different body shapes and skin conditions, meeting the needs of various clinical situations, minimizing pressure and damage to the patient's skin, and better assisting the puncturist in the catheterization operation. It does not require complex manual operations, reduces the difficulty of operation, and improves the convenience, efficiency and success rate of the puncture operation.

The facing sides of the plate 4 are respectively provided with an airbag 2, and the support seat 1 is provided with an airbag inflation and deflation control device which is connected to the airbag 2 and is used to control the inflation and deflation of the airbag 2. A slide groove 7 is provided on one side of the support seat 1, and a sliding storage plate 8 is provided in the slide groove 7. A drawer 9 is provided on the other side of the support seat 1. The lower side of the support seat 1 is connected to a height-adjustable bracket 10, and the lower side of the height-adjustable bracket 10 is connected to a base 11. The lower side of the base 11 is provided with a running wheel 12, and the running wheel 12 is equipped with a brake device 13. The rear side of the base 11 is provided with a storage basket 14.
[0015] Furthermore, a handle 15 is provided on the support base 1 .
[0016] Furthermore, a remote control bracket 16 is installed on the height-adjustable bracket 10 .
[0017] Specifically, the airbag 2, telescopic rod 5, airbag inflation and deflation control device, height-adjustable bracket 10, running wheel 12, brake device 13, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described in detail here.
[0018] The working principle of this embodiment is as follows:
[0019] The airbag inflation and deflation control device integrates a microcontroller (such as a single-chip microcomputer), a button sensor, an air pump, a solenoid valve, and a remote control. Air intake and deflation are controlled by a button 6 (the same color as the airbag 2) in the U-shaped fixing groove base 11. The microcontroller (MCU), the core of the system, receives signals from the button 6 and controls the operating states of the air pump and solenoid valve according to pre-set program logic. When the button sensor is pressed, it sends a signal to the MCU. Depending on the number of times the button is pressed (i.e., once or twice), the MCU recognizes different operating instructions. The air pump is used to inflate the airbag 2. When the MCU receives an intake instruction, it activates the air pump and delivers gas to the corresponding airbag 2. The solenoid valve controls the flow direction of gas and implements the deflation function. The solenoid valve connects the airbag 2 to the atmosphere, allowing the gas in the airbag 2 to be discharged. When the button 6 is pressed for the first time and then extended, the MCU recognizes it as an intake instruction, activates the air pump, and begins to inflate the airbag 2. The MCU stops the air pump and maintains the inflated state until the button is released. If the button is long-pressed again (i.e., a second long-press), the MCU recognizes this as a deflation command and controls the solenoid valve to open, connecting airbag 2 to the atmosphere and discharging gas from airbag 2. This continues until the button is released, at which point the MCU closes the solenoid valve, stopping the deflation process. Furthermore, the remote control's up and down buttons 17, which are the same color as the airbag 2, can be used to adjust the air intake and deflation of the airbag 2, respectively. For more information on airbag inflation and deflation control devices, see patent publications CN102512274B, CN104921906B, and CN219049372U.
[0020] The height-adjustable bracket 10 includes an adjustable upper end and a fixed lower end, which are adjustable via an electric actuator. The height of the height-adjustable bracket 10 can be adjusted using up and down buttons 18 on a corresponding electric actuator remote control. A remote control holder 16 can be used to store the remote control. Specifically, the remote control for controlling airbag inflation and deflation and the electric actuator remote control are combined into a single housing.
[0021] The lifting plate 4 height can be adjusted by utilizing the telescopic rod 5, and the lifting plate 4 can be manually raised or lowered to adjust the height of the blue airbag 2 and the purple airbag 2. The sliding storage plate 8 can be pulled out and retracted along the chute 7.
[0022] The present invention is used to assist in the process of peripherally inserted central catheter (PICC). The degree of arm support and skin tightening of the patient is adjusted by inflating and deflating multiple air bags 2, thereby achieving firm fixation of the puncture site and precise adjustment of skin tension. The height of the support seat 1 is adjusted by using the height-adjustable bracket 10, the position of the base 11 is adjusted by the walking wheel 12, and the height of the upper air bag 2 is adjusted by the telescopic rod 5, thereby adjusting the height of the patient's arm and the direction in which the skin needs to be tightened. This not only improves the patient's comfort and safety, but is also suitable for patients of different body shapes and different skin conditions, meeting the needs of various clinical situations, minimizing pressure and damage to the patient's skin, and better assisting the puncturer in the catheterization operation. There is no need for complicated manual operation, which reduces the difficulty of operation and improves the convenience, efficiency and success rate of the puncture operation.
