Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly belongs to a radial artery blood sampling wrist type pressure hemostasis device.
Background
The arterial blood gas analysis is an important clinical auxiliary examination means, and has important guiding significance for diagnosis and treatment of patients with respiratory disorder, hypoxemia, acid-base imbalance and the like, implementation of CPR, adjustment of mechanical ventilation and differential diagnosis of diseases. In clinical practice, blood collection is performed through the radial artery, brachial artery, femoral artery, etc. Because the radial artery position is superficial, easy to touch and beat, does not expose privacy, convenient operation, and the patient is easy to accept and often selected, but because the radial artery pressure in the organism is higher, hemorrhage, local plaque, hematoma easily appear after the puncture, so often need to press the hemostasis 5-10min locally after the radial artery blood sampling, need to press 30min or even longer time to some special patients. After the traditional blood collection is finished, an operator presses the puncture point by using two cotton swabs, the contact area of the cotton swabs and the skin is small, and the puncture point of the needle head, the skin and the blood vessel cannot be covered; and because the puncture angles are different, the skin puncture point may deviate from the actual puncture point of the blood vessel; furthermore, the local pressure is strong, in order to ensure the pressing effect, a user may increase the pressure involuntarily, and complications such as pain, pale palms, numbness, local skin pressure and the like may occur due to the long-time local pressure; traditional manual cotton swab pressing requires continuous pressing by a nurse at a walking bed for more than 10 minutes, even longer; the hospital is lack of human resources, the treatment task is heavy, the conditions of partial pressing time shortage, hand changing of a pressing person, replacement of the pressing person and the like can be caused, the pressing time and the pressing force degree are interrupted, and the partial bleeding and the like can be caused.
In order to solve the problems, workers in the field also carry out a great deal of research in recent years, for example, hemostasis is carried out after radial artery blood sampling by using cotton ball combined wide adhesive plaster, air bag type band-aid, disposable empty needle caps, elastic pulse pressing belts, button elastic pulse pressing belts, sterile small gauze folding and covering combined compressor pressing and the like, and the effect superior to that of the traditional cotton swab pressing hemostasis is achieved, but the mode is complex to operate, cannot accurately measure pressure and guarantee pressing force, can only be judged according to clinical experience, and cannot carry out pressure monitoring and adjustment according to different people; there is a continuing need to investigate the hemostatic procedures after radial artery blood sampling.
Disclosure of Invention
The utility model provides a radial artery blood sampling wrist type pressure hemostasis device, which solves the problems in the prior art.
A radial artery blood sampling wrist type pressure hemostasis device is characterized by comprising a wrist strap, wherein fastening parts are arranged at two ends of the wrist strap, a double-layer structure is arranged in the wrist strap structure, an air bag is fixed between the double layers of the wrist strap and connected with an inflation tube, the other end of the inflation tube is connected with a one-way air inlet valve, and the one-way air inlet valve is positioned outside the wrist strap; the one-way air inlet valve is connected with the three-way valve, one interface of the three-way valve is connected with the sphygmomanometer, the other interface of the three-way valve is connected with the injector with 10ml of air, and when the air inlet ball of the sphygmomanometer is used for inflating, the three-way valve is kept in a state that the one-way air inlet valve, the sphygmomanometer and the injector are communicated.
Further, the fastening part is a magic tape.
Furthermore, the wrist strap is made of cotton cloth.
Further, the syringe is a 20ml syringe.
The use method of the utility model comprises the following steps:
after a patient pulls out a needle, a prepared transfusion adhesive is used for protecting a puncture part, the puncture point is pressed by hands, the wrist type pressure hemostasis device provided by the utility model is quickly replaced, an air bag of the pressure hemostasis device is aligned with the puncture point, two ends of a wrist strap are fixed on the wrist of the patient through magic tapes, a one-way air inlet valve is connected with a three-way valve, when an air inlet ball in a blood pressure meter is inflated, the three-way valve is kept in a state that the one-way air inlet valve, the blood pressure meter and a 20ml injector are communicated, the inflation is stopped when the air inlet ball is inflated to exceed the average arterial pressure of the patient, the skin pressure feeling of the patient is inquired, the skin color of the palm and the finger end of the patient is evaluated, the pressure is finely adjusted by drawing and pushing the 20ml injector until a comfortable pressure value of the patient is reached, and the three-way valve is quickly separated to enable the one-way air inlet valve to be in a closed state. After the air bag presses the puncture part for 10min, observing whether the puncture point has blood leakage and subcutaneous hematoma, if not, releasing the pressing, and if so, continuing the pressing. After pressing, the air in the air bag is pumped out by a syringe, and the wrist band is removed.
When the radial artery blood sampling wrist type pressure hemostasis device is used, the contact area (3cm multiplied by 4cm) of the air bag and the skin is about 20 times of the pressing area of a cotton swab, and both a needle insertion puncture point and a blood vessel puncture point can be contained to achieve an effective pressing area; because of the structure including the one-way air inlet valve, after the inflation is finished, the wrist type pressure hemostat air sac can not leak air when the three-way valve is separated, and the pressure can be kept, thereby ensuring the effective pressing area, the pressing strength and the continuous pressing time and achieving the good hemostasis effect. The air bag of the pressure hemostat is placed above the puncture point and is rapidly expanded after being inflated, so that the characteristics of high puncture point and low periphery are formed, the compression point is accurate, the pressure is effective, peripheral arteriovenous are suspended without being compressed, the local blood supply is not influenced, and the situations of uneven force and strong local pressure caused by cotton swab pressing, pain, pale palm, numbness feeling, local skin compression and other complications possibly caused by long-time pressing are reduced; the patient is comfortable, can freely move, and does not need medical staff to carry out bedside nursing, and the active effect of relieving the shortage of the hospital manpower resources is achieved.
