Affected by the new crown epidemic, the gap between the supply and demand of ventilator in the world is growing. With the spread of the epidemic in the world, a large number of countries are introducing ventilator equipment. Respirator matching respirator masks and other silica gel accessories are also listed as the global supply of nervous substances.
Characteristics of liquid silica gel (LSR)
Liquid silicon rubber, or LSR for short, is a kind of non-toxic, heat-resistant and high resilience flexible thermosetting material.
The biocompatibility and low sensitivity of liquid silica gel (LSR) minimize the risk of allergic reactions in use. And because of its hygiene, bacteria and fungi can hardly grow and spread. These characteristics make it an ideal material for short-term and long-term transplant equipment.
Liquid silica gel products are elastic, durable, transparent, can accept UV irradiation and anti tension. Unlike traditional rubber, liquid silica gel can withstand extreme temperature, and will not deform from - 55 ℃ to 200 ℃. Because of this characteristic, the instruments made of liquid silicone rubber can be sterilized under high pressure.
Liquid silica gel also has extraordinary permanent compression deformation performance, can be made into different wall thickness in the same part, and the material has strong durability and plasticity.
Soft and skin friendly comfort, hardness close to human skin (0 shore hardness)
Because of these characteristics, liquid silica gel has become the key component of most respirator silica gel masks and medical silica gel devices such as oxygen delivery tubes. Before the outbreak of the epidemic in Europe and the United States, the ventilator became one of the most effective therapies. The ventilator was in short supply. Even Tesla, Ford and other automobile manufacturers began to switch to ventilator production. The manufacturers of silica gel masks related to ventilator were in short supply and kept on working.
2、 Production technology of respirator mask
The production process of respirator mask mainly adopts liquid silica gel injection molding technology. After heating the mold on the high-precision silica gel mold to a certain temperature, the silicone collagen material (AB component liquid silica gel) is mixed into the mold by the high-temperature and high-pressure injection molding machine, and then the silicone products have been finished.
Respirator masks as medical accessories have high requirements. In addition to the medical grade materials, they also have high requirements for the production environment. They need to reach the 100000 grade dust-free workshop. The production qualification needs to meet the ISO13485 quality management system certification and other necessary conditions, and the general liquid silica gel molding speed is slow.
3、 Types of respirator liquid silicone mask
The respiratory mask and anesthesia mask products for medical equipment are basically medical grade liquid silica gel through injection molding. According to the different materials and processes of the products, they can be divided into full silica gel mask and rubber mask. It is understood that the respirator mask used to fight against the epidemic is full silica gel mask, especially the liquid silica gel nose mask and liquid silica gel nose pad mask.
There are several kinds of respirators on the market, including liquid silicone masks for medical anesthesia:
1. Liquid silicone full face mask
Body silicone full face mask is characterized by covering the mouth and nose. Patients can use mouth breathing or nose breathing. It is beneficial for patients who are accustomed to using mouth breathing during sleep. It can avoid air leakage through the mouth. It is suitable for patients with other respiratory diseases, such as COPD patients. Compared with other kinds of face masks, full face masks are more likely to leak air, which will affect drinking water and communication to a certain extent. For the patients who have not serious nasal obstruction and use nasal breathing during sleep, consider the following two kinds of masks.
2. Liquid silicone nose mask
The liquid silica gel nose mask covers the nose, breathes through the nose, has wide vision, is simple and comfortable, and is widely used for general patients. It's easy to leak air through the mouth. Friends who are used to breathing through the mouth prefer to choose nose mask.
3. Liquid silicone nose pad mask
The mask has the least contact with the face skin, is light and comfortable, breathes through the nose, has wide vision, is the first choice for claustrophobic patients, and can be used for patients with light snoring. The inserted nasal pad may stimulate the nasal mucosa significantly when the pressure is high. It is not recommended for the patients with deviated nasal septum, especially for the patients with breath through mouth. The treatment discount for the patients with air leakage through mouth will be large.
It is understood that in the process of fighting the epidemic, there is a great demand for liquid silicone nose mask and liquid silicone nose pad mask. Medical silica gel equipment has strict requirements on production process and production environment. Pre production production equipment and production environment management test reports need field verification before they can be qualified for production. Compared with traditional medical raw materials, liquid silica gel has unique advantages, and it is also the inevitable trend of medical equipment raw materials in the future.
LiCo silica gel, a liquid silica gel supplier of the world's top 500 enterprises, has two floors of 100000 level dust-free workshop, more than 30 sets of imported injection equipment, equipped with standard laboratory, mold design center, quality control center, and has obtained more than ISO9001 and ISO13485 quality system certification. It is specialized in providing customers with medical grade liquid silica gel application solutions and medical silica gel accessories application customization services. The company has an excellent professional project team and German imported Abbott production equipment, and has established a long-term strategic partnership with a number of international brand companies, mainly developing and producing high-precision liquid silica gel mold and products, products covering maternal and infant, medical, digital electronics, toilet, adult supplies, automotive electrical and other industry applications.
