Description

Technical Field

[0001] The utility model relates to the field of medical infusion devices, in particular to an auxiliary fixing and protecting device for infusion of a venous indwelling needle. Background Art

[0002] The intravenous infusion indwelling needle, also known as the intravenous cannula needle, is a cannula commonly used for intravenous infusion. It consists of a stainless steel core, a soft outer cannula and a plastic needle seat. When in use, the outer cannula and the needle core are inserted into the blood vessel together. After the outer cannula is sent into the blood vessel, the needle core is withdrawn, leaving only the soft outer cannula in the blood vessel for infusion treatment. This indwelling needle design allows it to be kept in the blood vessel for a long time, generally for 3 to 5 days, reducing the pain of multiple venous punctures for patients and also playing a role in protecting blood vessels.

[0003] Through research and analysis, it was found that the existing intravenous infusion needles have some obvious defects when in use. First, the fixing method is relatively simple, which can easily cause the needle to shift or fall off, increasing the patient's pain and infusion risk. Secondly, during a long period of infusion, the patient's arm is prone to feel stuffy and uncomfortable, and the lack of a good ventilation environment affects the patient's comfort. In addition, the existing device lacks a convenient calling function. When the patient has an emergency or the infusion is completed, it is difficult to notify medical staff in time, and there are certain safety hazards. In summary, the existing intravenous infusion needles have obvious defects in fixing stability, breathability, and emergency calls, which need to be improved to enhance the patient's infusion experience and safety.

[0029] like Figure 1 As shown, a ventilation groove 51 is provided on the surface of the wrist support cushion 5 .

[0030] Embodiment 2:

[0031] The difference between this embodiment and embodiment 1 is that:

[0032] like Figure 3 As shown, a shell 31 is provided on the pager 3, and the shell 31 is fixed in the reserved groove 21 on the hard board 2. A wireless transmitter 33, a circuit board 34, a button battery 35, a call button 36, and an indicator light 37 which are electrically connected in sequence are fixed on the shell 31. The wireless transmitter 33, the circuit board 34, and the button battery 35 are located inside the shell 31, and the call button 36 and the indicator light 37 are located outside the shell 31. A packaging cover 32 is fixed at the reserved opening position on the shell 31.

[0033] like Figure 4 , Figure 6 As shown, the transparent elastic band 7 sequentially fixes the mutually adaptable sub-buckle 72 and the female buckle 73 in a direction away from the Velcro 8.

[0034] like Figure 1 , Figure 2 As shown, the Velcro 8 at the end of the transparent elastic band 7 is a fleece surface, and the Velcro 8 on the lower surface of the flexible silicone shell 1 is a hook surface.

[0035] like Figure 4 As shown, the surface of the transparent elastic band 7 is distributed with a plurality of breathable micropores 71 in a rectangular array structure.

[0036] The hand warming device 9 includes an electric hot water bag 91, and a display thermometer 92 and a charging port 93 are sequentially installed on the outer side of the electric hot water bag 91, and the display thermometer 92 and the charging port 93 are connected by a wire;

[0037] like Figure 7 As shown, the size of the hand warming device 9 is adapted to the wrist support cushion 5. When the electric hot water bag 91 on the hand warming device 9 needs to be heated, the user can energize the charging port 93 on the hand warming device 9, and the heating temperature of the liquid in the electric hot water bag 91 can be observed in real time through the thermometer 92 to prevent the heating temperature from being too high and to avoid scalding the patient during the arm warming process. After the electric hot water bag 91 is energized, the current will directly act on the heating wire in the electric hot water bag 91 through the charging port 93. The heating wire converts electrical energy into thermal energy to heat the liquid inside the electric hot water bag 91, so as to achieve the effect of heating and keeping the electric hot water bag 91 warm.

[0038] Working principle: When the utility model is used, the patient places his arm on the upper side of the flexible silicone shell 1, the patient's fingers pass through the finger separation belt 4, and the wrist is resting on the wrist support cushion 5. When the hand warming device 9 is not powered on for heating, the liquid in the hand warming device 9 provides soft support. When the ambient temperature is low and the patient's arm needs to be kept warm, the hand warming device 9 is powered on and heated to a specified temperature to increase the local temperature of the arm and promote blood circulation, which not only helps to relieve the discomfort caused by the cold, but also allows the liquid medicine to enter the body more smoothly, thereby improving the treatment effect. At the same time, the warm feeling can also bring psychological comfort to the patient, relieve tension, and enhance the comfort of the infusion process.

[0039] The medical staff finds the vein site of the patient's arm and uses the indwelling needle to perform the needle operation. Subsequently, multiple transparent elastic bands 7 are passed over the top of the patient's arm, and the hairy surface of the Velcro 8 at the end of the transparent elastic band 7 is bonded and fixed with the hook surface of the Velcro 8 on the lower surface of the flexible silicone shell 1. The transparent elastic band 7 is made of elastic transparent material. On the one hand, the transparent elastic band 7 can make the flexible silicone shell 1 and the patient's arm appropriately tightened, which can adapt to the different sizes of arms of different people and keep the patient's venous channel unobstructed. On the other hand, the transparent elastic band 7 can fix the position of the indwelling needle on the patient's arm to prevent the indwelling needle from shifting or falling off as the patient's arm moves. At the same time, the transparent elastic band of the transparent material 7, it is convenient for medical staff to observe the position of the indwelling pillow in real time; the sub-button 72 and the female button 73 on the transparent elastic belt 7 are mutually buckled, which is convenient for medical staff to replace the transparent elastic belt 7 fixed on the ear hook 6 as a whole in time to keep the transparent elastic belt 7 clean and tidy. The breathable micropores 71 on the transparent elastic belt 7 can play a role of ventilation, reducing the discomfort caused by skin moisture, which is beneficial to the health of the skin around the indwelling needle. In addition, the setting of the through hole 12, the through hole 22 and the breathable groove 51 also ensures a good ventilation environment for the patient's arm, avoiding the stuffy feeling caused by long-term infusion. The flexible silicone shell 1 and the wrist support cushion 5 are made of elastic material, which ensures the comfort of the patient's arm.

[0040] The button battery 35 in the pager 3 provides power for the pager 3 to ensure that it can work continuously and stably. The indicator light 37 is used to display the status of the pager. The wireless transmitter 33 is used to send wireless signals to the receiver of the nurse station. The circuit board 34 integrates various electronic components and circuits in the pager 3 to ensure that each component can work normally and coordinately. When an emergency occurs during the patient's infusion process, or when the infusion is completed, when the patient presses the call button 36, the indicator light 37 may light up or flash to prompt the nurse station that the call signal has been received, so that the medical staff at the nurse station can immediately receive the signal and respond.
