Description

A radial artery puncture auxiliary function pad

technical field

The utility model relates to the technical field of medical devices, in particular to a radial artery puncture auxiliary function pad.

Background technique

The radial artery is the most commonly selected artery for invasive arterial blood pressure monitoring and blood gas analysis. Radial artery puncture is a necessary step for radial artery interventional therapy. The indications for radial artery puncture include:

1. When the blood collector is in severe shock or critical illness, blood transfusion is required through arterial infusion to increase blood pressure and improve blood supply to important organs such as the heart, brain, and kidneys;

2. Blood collection for critical and major surgery needs to be directly monitored for arterial blood pressure;

3. Arterial blood collection is required for laboratory examination;

4. Perform selective arteriography through arterial puncture, or inject anti-tumor drugs, and perform regional chemotherapy;

5. Autologous blood transfusion and blood dilution; and so on.

Among them, radial artery blood collection is more common in the clinical blood collection process. Compared with femoral artery and carotid artery blood collection, radial artery blood collection is more convenient and faster for blood collectors.

The radial artery is located on the inside of the radius, away from the cephalic vein, and there are no large blood vessels and nerves around it. Therefore, in the process of blood collection, compared with the femoral artery and the carotid artery, the risk is minimal, the operation is simple, labor-saving, time-saving, and The phlebotomist suffers less pain, and the puncture success rate is high.

Choosing the radial artery for blood collection has the following advantages:

1. The radial artery is located in the upper extremity, which is superficial and easy to reach for obese blood samples. According to clinical experience, radial artery blood collection is simpler and easier to operate and has fewer complications.

2. It is more common to draw blood from the upper extremities, and blood drawers are more inclined to choose a syringe with a short needle to draw blood, so blood drawers have a higher degree of acceptance.

3. The position of the radial artery is superficial, so the angle of needle insertion is small, which is easy to compress and stop bleeding, which is convenient for observation.

4. For those with blood coagulation dysfunction and bleeding tendency who need to closely observe the puncture point, because the radial artery is superficial, there is no need to expose the blood collection too much, and the condition of the puncture site can be observed at any time, which greatly reduces the The workload of nurses has improved the rescue efficiency.

5. There are no important blood vessels and nerves near the radial artery, and it is not easy to cause blood vessel and nerve damage, and the damage to the venous wall is small, and it is not easy to draw venous blood.

6. From the perspective of humanization, the radial artery blood collection does not require high environmental requirements. The arterial blood collection only needs to use the exposed forearm, and no special posture is required. The blood collection person can take a sitting or lying position, and does not need to take off his pants, which is extremely convenient. It also saves a lot of time, reduces the fear of phlebotomists, and protects the privacy of phlebotomists. Winter is more suitable for phlebotomists in outpatient clinics.

Under normal circumstances, when medical staff perform radial artery puncture, the hand of the blood collector does not have any auxiliary pad (also known as the radial artery blood collection pad). If the hands are padded with other items, it is neither comfortable nor easy to operate, and the safety of phlebotomists and medical staff is also lacking.

Clinical studies have shown that the use of an auxiliary pad (radial artery blood collection pad) can help improve the success rate of radial artery puncture (eg, radial artery puncture for arterial blood collection) in junior nurses.

The existing radial artery blood collection pad is usually placed on the root of the palm of the phlebotomist, so that the back of the palm is curved in an inverted arcuate shape, the purpose is to straighten the blood vessel, and try to ensure that the phlebotomist maintains this posture as still as possible.

In the existing radial artery blood collection pad, one end of the palm support pad is hinged with one end of the arm support pad to form a complete radial artery blood collection pad. The lower part of the palm support pad is provided with an air cushion that communicates with an air source, and is adjusted by the air cushion. The angle between the arm support pad and the palm support pad.

The disadvantage of the existing radial artery blood collection pad is that the hinged connection method makes it difficult to disassemble the palm support pad and the arm support pad, which is inconvenient for storage; the angle between the arm support pad and the palm support pad is adjusted by the air cushion, The air cushion is connected to the external air source through the trachea, resulting in a large volume of the product, which requires a lot of space for placement, which is inconvenient for clinical use.

Another existing radial artery blood collection pad adopts a bolster body with a height of the front side higher than the height of the rear side, and an angle adjustment plate is rotatably connected to the edge where the front side of the bolster body intersects with the upper bottom surface, A spring is then arranged between the front side of the bolster body and the angle adjustment plate, and the degree of dorsal curvature of the palm placed on the angle adjustment plate is adjusted by the spring.

The disadvantage of the existing radial artery blood collection pad is that the adjustment of the spring is inconvenient, the control and adjustment of the elastic force is cumbersome, and the volume of the cushion body is large, and the angle adjustment plate also needs to occupy a certain space, so the The product as a whole needs to take up a lot of space for placement, which is not convenient for clinical use.

Another existing radial artery blood collection pad, designed in the form of a pad, includes: a fixing plate for fixing on the edge of the bed on one side of the C-arm operation bed close to the head end, and a C-arm operation bed along the C-arm operation bed from the fixing plate The shelf is formed by extending in the length direction. The upper surface of the shelf is arranged with a lifting pad for raising the back of the wrist. The lifting pad is fixed with a slider. The shelf is arranged with a guide rail on one side of the board along its extending direction. , the slider and the guide rail form a guide fit of the slide rail.

The existing radial artery blood collection pad has the disadvantage that it is only suitable for the C-arm operation bed, the application is limited, the height of the lifting pad is fixed and difficult to adjust, and the adjustment and fixing of the slider are cumbersome and inconvenient to use.
