Medical equipment is still old and still shining
Glass syringe, multi-head stethoscope, pathological section staining frame... In mid-August, the reporter stepped into the Provincial Cancer Hospital History Exhibition Hall, a medical device that was used many years ago, and written that the medical workers were simple, hard-working, and dying. Legend.
Glass syringe
A syringe is a common medical device. As early as the 15th century, Italian Katinel proposed the principle of the syringe. It is generally believed that Pravoz of France invented a silver syringe in 1853 with a capacity of 1 mL. After that, the Englishman Ferguson was the first to use a glass syringe.
In the exhibition hall of the Provincial Cancer Hospital, various types of glass syringes, syringe sets and syringe needle disinfection tools are housed. One of the 1988 5mL syringes was supplied by the hospital's supply room, including five syringes and 20 needles. The syringe is well preserved and the needle is still sharp. In addition, there are two sets of syringes with needle boxes in the 1960s, each with a 2mL glass syringe and a 1mL blue-core glass syringe.
According to the staff of the exhibition hall, in the 1960s and 1970s, glass syringes were commonly used in hospitals. The transparency of the glass is good, and the situation of injecting the drug can be seen. In addition, there are also syringes made of glass tubes and metal, which are sterilized by boiling, and the needles can be sharpened and reused. Unlike modern disposable syringes, glass syringes require repeated use, and if disinfection is not complete, it can easily lead to cross-infection. Therefore, glass syringes and needles need to be sterilized before they can be used. The collection contains a set of needle disinfection boxes from the 1960s, which can hold about 100 needles. The texture and shape of the metal reflect the distinctive characteristics of the times.
Because the use of glass syringes requires a lot of manpower and material resources for disinfection, storage, collection, distribution, etc., it is not as convenient to use disposable plastic syringes. Therefore, most hospitals no longer use this traditional syringe, and glass syringes have basically withdrawn from the historical arena. Currently, the most widely used is a disposable syringe with a plastic texture. It is understood that scientists have developed a high-speed high-pressure ejector that injects a drug into the body through a needle-free syringe. This law is expected to end the era of pain.
Multi-head stethoscope
The stethoscope is known as the "medical flute" and also shows the doctor's feelings of saving the wounded and dying. Among the medical equipment and equipment collected in the exhibition hall, a multi-headed stethoscope used in the 1950s and 1960s was very eye-catching. At that time, it was an important device for clinical consultation and teaching, which allowed 8 people to auscultate at the same time. Due to the age, there are only seven heads left.
The multi-head stethoscope has been an indispensable instrument for clinical examination of the body. It can perform auscultation on patients such as lungs and heart, and provide clinical clues for further diagnosis of diseases. It belongs to the field of clinical clinical device technology. A round metal probe, connected to a plurality of rubber tubes, earplugs, and a multi-headed stethoscope of the sound tube, has a sound collection function and also has a filtering effect. Through auscultation, the doctor can diagnose the relevant organs according to the characteristics and changes of the sound, such as the frequency of the sound, strength, weakness, interval time, noise, etc.
At that time, because the stethoscope was necessary for diagnosing chest diseases, heartbeat blood pressure and other vital signs, it made a great contribution to the clinical examination of experienced doctors. Respiratory specialists can clearly hear the lungs breathing sounds and diagnose lung lesions and diseases through a multi-head stethoscope, which can even be used against many instruments. In the cardiovascular aspect, it can also be used to listen to heart rate, heart sounds, vascular murmurs, and blood pressure. Older medical workers have cured countless patients with these simple devices. After more than 60 years of change, the multi-head stethoscope completed the mission of clinical medical diagnosis and glory to withdraw from the medical arena.
