Symptoms of Alzheimer's disease
“The memory of the old man at home is getting worse and worse. It's getting old and confused.†This is a word often spoken by the children of older people in the family. But what they don’t know is that there’s a hidden one in this sentence. Fearful facts: These elderly people are very likely to suffer from Alzheimer's disease and have already had an early performance. One of them is the deterioration of memory. With aging, memory loss, memory deterioration is an indisputable fact, then as children, how to distinguish which memory is the normal performance of old age, and what is the sign of Alzheimer's disease? The reporter interviewed the director of the Department of Neurology of the Second Hospital of the City, Zhang Yan, and listened to her to answer questions. I remember what happened in Qing Qing
Zhang Jiabao is 60 years old this time. In the most recent period, her children discovered that the memory of the old man is becoming worse and worse. Before the children go to work, they remind her to remember taking medicines and put medicine bottles on the coffee table. After returning from work, she found that she did not Eat; free to put things on your own, how can you not think of where to put up for the second time. But what's surprising is that she remembered very clearly what she had done before, such as when she worked in a year, when she got married, and when she traveled to a foreign country... and she remembered everything very clearly. Listen to the younger generation.
Zhang Hao said that this situation of Zhang Hu’s mother is the initial symptom of Alzheimer's disease. It is very clear to remember what happened before, but it can't remember what happened in the near future. This is called near memory disorder. If children find such a situation, they should be vigilant and send the elderly to a hospital for professional examination and early intervention.
Extraction disorders are normal storage disorders are high risk signs
There is another kind of performance in the poor memory of the elderly. Zhang Jian gave an example of an image. The two old people had eaten eggplant on the night before. As a result, they couldn't remember the next day. How was an old man going through the family to the eggplant? A reminder of the shape of the food and eggplant reminds you that you can remember to eat eggplant, and the second old man can't remember what he eats no matter what kind of reminders his family members do. So which of these two elderly people is suffering from Alzheimer's performance?
"The first old man's case is called the extraction barrier of memory. The information that will have occurred has already been put into the brain. It is only an obstacle when it is extracted." Zhang Qian said that as the age increases, the old man must be accompanied by memory. In the recession, the barrier of memory extraction is a normal manifestation. The condition of the second old man is called the storage barrier of memory. There is no information stored in the brain at all. This is one of the symptoms of Alzheimer's disease.
Surgical gowns, as necessary protective clothing during the surgery, are used to reduce the risk of medical personnel coming into contact with pathogenic microorganisms, and can also reduce the risk of pathogenic microorganisms spreading between medical staff and patients. It is a safety barrier for sterile areas during surgical operations .
* Scope of use of surgical gowns: can be used for surgical operations, treatment of patients; anti-epidemic inspection in public places; disinfection in virus-contaminated areas; can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other fields.
* Classification of surgical gown
1. Cotton surgical gown. Medical institutions are the most widely used and most dependent surgical gowns. Although they have good breathability, they have poor barrier protection. The cotton material is prone to shedding of flocs, so that the annual maintenance cost of the ventilation equipment of the hospital will also have a large burden.
2. High density polyester fiber fabric. This type of fabric is mainly composed of polyester fiber, and conductive materials are embedded on the surface of the fabric, so that the fabric has a certain antistatic effect, thereby improving the comfort of the wearer. This kind of fabric has certain hydrophobicity, it is not easy to produce cotton de-flocking and the advantages of high reuse rate. This kind of fabric has good antibacterial effect.
3. PE (polyethylene), TPU (thermoplastic polyurethane elastic rubber), PTFE (teflon) multi-layer laminating film composite surgical gown. The surgical gown has excellent protection performance and comfortable breathability, which can effectively block the penetration of blood, bacteria and even viruses. But the popularity in China is not very wide.
4. (PP) polypropylene spunbond fabric. Compared with the traditional cotton surgical gown, the appearance of this material is because of its low price, and has certain advantages such as antibacterial and antistatic, so it can be used as a material for disposable surgical gowns, but the ability of this material to resist hydrostatic pressure is relatively Low, and the blocking effect of the virus is relatively poor, so it can only be used as a sterile surgical gown.
5. Water spur cloth composed of polyester fiber and wood pulp. Generally only used as a material for disposable surgical gowns.
6. Polypropylene spunbond-meltblown-spun. Adhesive composite non-woven fabric (ie SMS or SMMS): This material is a high-quality product of a new type of composite material. Hydrostatic pressure capacity. SMS non-woven fabrics are widely used at home and abroad, often used to make high-grade surgical gowns.
* Structural design of surgical gown
New protective surgical gown
By providing a protective collar, the neck of the operator can be kept warm. By setting a hand guard pocket, it is helpful for the operating staff to temporarily put their hands in the hand guard pocket while waiting during the operation, which plays a protective role, and is more in line with the principles of aseptic operation and occupational protection.
By setting the contraction cuff, it is helpful to fit the cuff to the wrist, prevent the cuff from loosening, and prevent the glove from slipping out during the operation, which may expose the operator's hand to the glove.
The design of the new humanized protective surgical gown has been improved in the key areas of the surgical gown. The two areas of the forearm and chest area are double thickened, and there are hand pockets in front of the chest and abdomen. By setting reinforcement tablets (double-layer structure) in key areas, it is helpful to improve the ability of surgical gowns to resist water permeability and improve safety.
* Performance of surgical gown
The performance of surgical gown mainly includes: barrier performance, comfort performance.
1. Barrier performance mainly refers to the protective performance of surgical gowns. Its evaluation methods mainly include hydrostatic pressure, water test, impact penetration, spraying, blood penetration, microorganism penetration and particle filtration efficiency.
2. Comfortable properties include: breathability, water vapor permeability, drape, quality, surface thickness, electrostatic properties, color, reflectivity, odor and skin sensitization, and the effects of design and sewing in garment processing. The main evaluation indicators are air permeability, moisture permeability and charge density.
* Why is the surgical gown green?
In the operating room, if doctors, nurses and other staff wear white coats, because the doctors always see bright red blood stains during the surgery, for a long time, occasionally turning their attention to the companion's white coat You will see spots of "green blood stains", which will confuse vision and affect the surgical effect. The use of light green fabric for surgical gowns can not only eliminate this green illusion due to visual complementary colors, but also reduce the fatigue of the doctor's optic nerve, thereby ensuring the smooth operation of the operation.
