Abstract
A disposable laryngoscope cover used in surgical operation is made of rubber or plastic and is a flexible thin-wall cover matched with a laryngoscope in shape and structure, one end of the flexible thin-wall cover contacting with the tail part of a laryngoscope lens is of a closed structure, and the other end of the flexible thin-wall cover is of an open structure. The laryngoscope cover is matched with a stainless steel laryngoscope for use, can effectively prevent disease infection caused by iatrogenic body fluid, has greatly reduced cost compared with a disposable laryngoscope, can be generally born by patients, and is easy to popularize in hospitals.
Description
One, technical field
The invention belongs to the disposable medical product, the disposable laryngoscope cover that particularly a kind of surgical operation uses.
Two, background technology
In Clinical Surgery's medical treatment, the trachea general anesthesia intubation technology is used more and more, and the requisite medical apparatus and instruments of this technology implementation is a laryngoscope, and the medical worker is by the help of laryngoscope, could be to patient's operation technique that applies general anaesthetic.The laryngoscope that hospital uses now mainly is the rustless steel laryngoscope, no matter is import, and still home-made, price is all very expensive, so each hospital often only is equipped with the laryngoscope of some, makes same laryngoscope can be used for different patients' general anesthesia operation by sterilization.But tend to occur the halfway phenomenon of sterilization in clinical, especially in recent years the sickness rate of hepatitis B, hepatitis C, acquired immune deficiency syndrome (AIDS) is more and more higher, these iatrogenic viruses are difficult to kill, though more make through sterilization but still the ratio of germ-carrying laryngoscope improves, this laryngoscope that carries disease germs is undoubtedly a kind of virus disseminating instrument, and it will make dopey patient suffer from new disease.For fear of the not thorough negative effect that produces of rustless steel laryngoscope sterilization, existing disposable at present laryngoscope comes out, but the price of disposable laryngoscope is not cheap, be difficult to make the patient generally to accept, in addition, the internal battery of disposable laryngoscope is a kind of polluter, if a large amount of the use will produce harmful effect to environment.
Three, summary of the invention
Problem at rustless steel laryngoscope and the existence of disposable laryngoscope, the technical solution adopted in the present invention is to dispose disposable laryngoscope cover to the rustless steel laryngoscope, this kind laryngoscope cover is compared with disposable laryngoscope, cost reduces significantly, cheap, be easy to be accepted by the patient, the use of this kind laryngoscope cover, can solve effectively because of rustless steel laryngoscope sterilization not thoroughly to cross infection that the patient produced.
The existing import of rustless steel laryngoscope that hospital uses, have again home-made, no matter be import or home-made, mainly contain two kinds of versions.A kind of shape and structure are as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, and alternative shape and structure are as Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Figure 9.As can be seen from the figure, though two kinds of laryngoscopes have outside the difference, similar, by eyeglass 1, be installed in light source 2 on the eyeglass, bearing 3 and handle 4 and form, eyeglass is
The tee section polymorphic structure or "-,
The variable cross-section polymorphic structure that shape is combined.Laryngoscope cover provided by the invention designs according to above-mentioned laryngoscope, its shape and structure and laryngoscope are complementary, and an end that contacts with laryngoscope eyeglass afterbody is an enclosed construction, and the other end is the open type structure, with rubber or plastics is that raw material is made, and forms a kind of flexible thin-walled cover.
Because during the general anesthesia operation operation, just the laryngoscope eyeglass enters the patient oral cavity, therefore, laryngoscope cover is designed to two types, and a kind of is the part cladded type, and a kind of is full cladded type.Part cladded type laryngoscope cover only is made of the portion's section that coats the laryngoscope eyeglass; Full cladded type laryngoscope cover is made up of the portion's section that coats laryngoscope eyeglass, coating laryngoscope bearing and coating laryngoscope handle, and each section is integrated.
Owing to mainly rely on the help of laryngoscope eyeglass work surface to carry out intubate during the general anesthesia operation operation, therefore, the key of laryngoscope cover design is to guarantee that the shape that puts this cover back laryngoscope eyeglass work surface does not change.Under the guidance of this principle, no matter be part cladded type laryngoscope cover or full cladded type laryngoscope cover, its portion's section that coats the laryngoscope eyeglass all can have two kinds of structures.A kind ofly be the structure that fits like a glove, a kind of is the part structure of coincideing.The characteristics of the structure that fits like a glove are: coat the work surface of the laryngoscope eyeglass Duan Weiyu of portion laryngoscope eyeglass and the variable cross-section polymorphic structure that non-working surface fits like a glove.The coincide feature of structure of part is: the variable cross-section polymorphic structure that the work surface that coats the Duan Weiyu of the portion laryngoscope eyeglass of laryngoscope eyeglass fits like a glove, partly coincide with the non-working surface of laryngoscope eyeglass.
Laryngoscope cover provided by the invention has the following advantages and good effect:
1, a laryngoscope cover only is that a patient uses, and has really played sterilization, isolated effect, has prevented the disease propagation that iatrogenic body fluid causes effectively.
2, compare with disposable laryngoscope, cost reduces significantly, and the patient generally can bear, and is easy to promote in hospital.
3, the exposure of overslaugh glottis and the operation of tracheal intubation not behind the laryngoscope cover on the rustless steel laryngoscope cover, easy to use, safe.
4, be easy to produce in batches with mould.
