Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an arterial blood gas needle sealing cap fixing device. Background Technology

[0002] Arterial blood sampling is a commonly used diagnostic method in clinical practice, but there is a significant risk of needlestick injury during the process of recapping the arterial blood gas needle after its use.

[0003] Current capping procedures mostly involve manual capping by healthcare workers, typically requiring the use of both hands. Specifically, one hand holds the arterial blood gas needle, the other holds the cap, and the two hands work together to insert the needle into the cap. However, this method not only increases the difficulty of the procedure but also significantly increases the risk of needlestick injuries and the risk of bloodborne infections for healthcare workers. Furthermore, the current capping technology for arterial blood gas needles is often limited by the length of the needle, which can distract healthcare workers in emergency situations or busy environments, further increasing the risk of needlestick injuries.

[0004] Therefore, how to provide an arterial blood gas needle sealing cap fixation device that can prevent needlestick injuries, assist medical staff in single-handed operation, reduce the risk of needlestick injuries, and improve the safety and efficiency of medical operations is a technical problem that urgently needs to be solved by those skilled in the art.

[0026] Please see Figure 1-3This embodiment provides an arterial blood gas needle sealing cap fixing device for fixing the arterial blood gas needle sealing cap 3. The arterial blood gas needle sealing cap fixing device includes a fixing cylinder 1 and a supporting base 2. The supporting base 2 has a disc structure. The bottom of the fixing cylinder 1 is connected to the center of the supporting base 2. The inner diameter of the fixing cylinder 1 is adapted to the size of the arterial blood gas needle sealing cap 3. The bottom surface of the supporting base 2 is provided with an anti-slip layer 21.

[0027] Specifically, this utility model provides an arterial blood gas needle sealing cap fixing device for fixing an arterial blood gas needle sealing cap 3. The device includes a fixing cylinder 1 and a supporting base 2. The supporting base 2 has a disc structure, and the bottom of the fixing cylinder 1 is connected to the center of the supporting base 2. The fixing cylinder 1 has a cavity structure adapted to the arterial blood gas needle sealing cap 3 (or a 2ml syringe needle cap, etc.). The inner diameter of the fixing cylinder 1 is adapted to the size of the arterial blood gas needle sealing cap 3, which can accurately and tightly accommodate the arterial blood gas needle sealing cap. In use, medical personnel can pre-insert the arterial blood gas needle sealing cap 3 upside down vertically into the fixing cylinder 1. The inner wall size of 1 is compatible with the size of the sealing cap 3 of the arterial blood gas needle, and can be firmly placed after insertion to avoid loosening or separation during use. After arterial blood collection is completed, the medical staff can hold the blood collection needle with one hand, align the needle tip with the sealing cap inside the fixing cylinder 1, and press down vertically to automatically retract the cap. No fine adjustment by hand is required. Compared with the current clinical practice where medical staff use both hands to retract the blood collection needle and insert it into the sealing cap 3 of the arterial blood gas needle, this changes the operation process from two-handed operation to one-handed operation, avoiding hand injuries caused by inaccurate insertion during the insertion process, reducing the risk of needlestick injuries, and improving the operation safety of medical staff.

[0028] In some possible implementations, a hanging hole 22 is provided through the support chassis 2.

[0029] Specifically, after the arterial blood gas needle sealing cap 3 is used up, it can be hung on the hook through the hanging hole 22 for easy placement and storage, thus avoiding loss.

[0030] In some possible implementations, a guide wall 11 is provided around the top of the fixed cylinder 1; the bottom of the guide wall 11 is integrally connected to the top of the fixed cylinder 1, and the diameter of the top of the guide wall 11 is larger than the diameter of the bottom of the guide wall 11.

[0031] Specifically, such as Figure 2-3 As shown, compared to inserting only the top of the fixed cylinder 1, the guide wall 11 expands the target range for the arterial blood gas needle sealing cap 3 to fall into the fixed cylinder 1. Even with some deviation, it can fall into the fixed cylinder 1 along the guide wall 11, which can effectively improve the accuracy of medical staff inserting the arterial blood gas needle sealing cap 3 into the fixed cylinder 1.

[0032] In some possible implementations, the inner wall of the fixed cylinder 1 is provided with a plurality of reinforcing strips 12 at intervals; the plurality of reinforcing strips 12 are all arranged along the length direction of the fixed cylinder 1.

[0033] Specifically, such as Figure 3 As shown, with the setting of several reinforcing strips 12, the outer wall of the arterial blood gas needle sealing cap 3 can be subjected to the squeezing force and friction of several reinforcing strips 12 after insertion, ensuring that the arterial blood gas needle sealing cap 3 is firmly embedded, improving the firmness of the arterial blood gas needle insertion into the fixing cylinder 1, and preventing the arterial blood gas needle from loosening or wobbling from side to side after insertion.

[0034] In some possible implementations, the anti-slip layer 21 is made of silicone or PVC material.

[0035] Specifically, the anti-slip layer 21 is made of silicone or PVC material, which improves the anti-slip effect and also makes it easier to clean later.

[0036] In some possible implementations, the support chassis 2 is made of stainless steel.

[0037] Specifically, the support chassis 2 is made of stainless steel. Stainless steel has good stability and durability, and its own weight provides stable support for the entire device, preventing it from tipping over during use.

[0038] In some possible implementations, the inner diameter of the fixed cylinder 1 is 8 mm; the diameter of the support base 2 is 5 cm, and the thickness of the support base 2 is greater than 2 mm.

[0039] Specifically, based on the actual size of the arterial blood gas needle sealing cap 3 in clinical practice, the inner diameter of the fixing cylinder 1 is designed to be 8mm to match the size of the arterial blood gas needle sealing cap 3; the diameter of the support base 2 is 5cm and the thickness of the support base 2 is greater than 2mm. Increasing the size and thickness of the support base 2 provides a stable base for the whole device, ensuring the stability of the device's center of gravity and preventing shaking during operation.
