Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a radial artery puncture and fixation stent. Background Technology

[0002] In clinical practice, various departments use arterial blood sampling to rapidly and in real-time measure multiple parameters of human arterial blood, including pH, partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), and electrolytes. Arterial blood sampling data objectively reflects changes in respiratory function and metabolic status in critically ill patients, and is of great significance for guiding oxygen therapy, adjusting mechanical ventilation parameters, and correcting acid-base imbalances. Meanwhile, with the development of interventional techniques and improvements in interventional materials, percutaneous coronary intervention via the radial artery, cerebral angiography, and vascular stent placement are now widely performed in clinical practice.

[0003] The radial artery on the palmar side of the wrist is superficial, easy to palpate, and facilitates hemostasis. Furthermore, it is not accompanied by any major blood vessels or nerves, minimizing the risk of vascular or nerve damage. Therefore, it is the preferred site for radial artery puncture and blood collection. During radial artery puncture, the palm faces upward and the back of the hand faces downward, keeping the patient's hand relaxed. A small pillow is placed under the wrist joint on the back of the patient's hand, elevating the wrist joint 5-8 cm and abducting the palm. The operator uses the index finger or index and middle fingers of the left hand to stabilize the vessel with the strongest pulsation. The right hand holds the arterial blood collection device in a pen-holding posture, 5-10 mm away from the positioning index finger, with the needle bevel facing upward and puncturing against the direction of blood flow.

[0004] When performing arterial puncture, it is generally necessary to support the patient's hand area to facilitate the operation. However, since the patient's hand needs to be kept fixed during the puncture process, traditional puncture stents cannot effectively assist in fixing the position of the patient's hand. At the same time, there is no device to assist in gripping, which makes it difficult for the patient to clench their fist to reduce pain when receiving the injection. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a radial artery puncture fixation stent. By setting a ligation component and a gripping component for use, it solves the problem that traditional puncture stents cannot effectively assist in fixing the position of the patient's hand, and at the same time, they do not have an auxiliary gripping device, which is not conducive to the patient clenching his fist to relieve pain when receiving injections.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A radial artery puncture fixation stent includes a fixation sponge, and further includes: the fixation sponge has a hollow structure in the middle, the fixation sponge is made of soft material, a clamping component is provided on the fixation sponge, an extension rod is fixedly connected to one side of the fixation sponge, a support rod is provided on the extension rod, and a gripping component is provided at the end of the extension rod away from the fixation sponge for the patient to grasp.

[0008] As a preferred embodiment of this utility model, the tightening component includes a strap, which is sleeved on the fixing sponge for binding and tightening the fixing sponge.

[0009] As a preferred embodiment of this utility model, the gripping assembly includes uprights fixedly disposed on both sides of the extension rod, with a handle fixedly connected to the upper end of the uprights.

[0010] The present invention has the following advantages:

[0011] In actual use, the patient can pass their hand through the cavity of the fixed sponge, then place their wrist on the support rod, and grip the gripping component. The support rod provides support for the hand, while the operator can tighten and fix the patient's hand using the clamping component. This provides sufficient fixation and prevents the patient from struggling during puncture. The grip is mainly for use when in pain, allowing the patient to clench their fist to reduce pain during injection. This method is more effective, stable, and safer, assisting medical staff in achieving accurate punctures. Attached Figure Description

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example 1, please refer to Figures 1-3 A radial artery puncture fixation stent includes a fixation sponge 1, and further includes: the fixation sponge 1 has a hollow structure in the middle, the fixation sponge 1 is made of soft material, a clamping component is provided on the fixation sponge 1, an extension rod 3 is fixedly connected to one side of the fixation sponge 1, a support rod 4 is provided on the extension rod 3, and a gripping component is provided at the end of the extension rod 3 away from the fixation sponge 1 for the patient to grasp;

[0018] In actual use, the patient can pass their hand through the cavity of the fixing sponge 1, and then place their wrist area on the support rod 4. The hand area is gripped on the gripping component, and the support rod 4 provides support for the hand. At the same time, the operator can tighten and fix the patient's hand by tightening the component, which can provide sufficient fixation and prevent the patient from struggling during puncture. The gripping component can be used to grip tightly when in pain, which is beneficial for the patient to clench their fist to reduce pain during injection. It has better effect, higher stability, and is safer, assisting medical staff to achieve accurate puncture.

[0019] Example 2, please refer to Figures 1-3 The tightening assembly includes a strap 2, which is fitted onto the fixing sponge 1 to tighten and bind the fixing sponge 1; the gripping assembly includes uprights 5 fixedly mounted on both sides of the extension rod 3, with a handle 6 fixedly connected to the upper end of the uprights 5. In actual use, the strap 2 can fix the patient's hand to the fixing sponge 1, thereby better fixing the hand area, assisting arterial puncture, reducing the patient's struggle and movement, and improving the success rate of puncture; under the action of the handle 6, the patient can grip it tightly when in pain, which is beneficial for the patient to clench their fist to relieve pain when receiving an injection.
