Abstract
The invention relates to a nasopharyngeal surface anesthesia apparatus comprising a nasopharyngeal surface anesthesia catheter (5) and a syringe (4). The nasopharyngeal surface anesthesia apparatus is used for sufficient deep nasopharyngeal surface anesthesia before sobering nasotracheal intubation and nasopharyngeal deep treatment for a patient, thus preventing the patient from feeling uncomfortable and rejecting when a catheter is inserted into a nasopharyngeal channel or during treatment. The existing nasopharyngeal catheter is provided with a certain amount of outlets of anesthetic, the syringe is provided, and the complete nasopharyngeal anesthesia apparatus is formed; therefore, chances of the patient feeling uncomfortable and rejecting are slimmer, and surgery is smooth. The nasopharyngeal surface anesthesia apparatus is applicable to sobering nasotracheal intubation and deep nasopharyngeal treatment.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of cavum nasopharyngeum topical anesthesia device.
Background technology
When clinical anesthesia is induced, some special circumstances are arranged, make patient retain autonomous respiration and trachea intubation under waking state.In order to reduce patient's misery, this just requires cavum nasopharyngeum and the glottis to patient before tracheal intubation to carry out sufficient topical anesthesia.In addition, when operation of diagnosis and treatment is carried out in the cavum nasopharyngeum deep, also need good topical anesthesia.In the prior art, the nebulization that the main device used is the topical anesthesia watering can clinically.
The metallic nozzle of topical anesthesia watering can is shorter, to the topical anesthesia of mouth and nose superficial part, can bring into play effect preferably, but can't reach desirable topical anesthesia effect to pharyngonasal cavity deep and glottis position.
In addition, the topical anesthesia watering can is not easy sterilization, easily causes cross infection to different patient's Reusabilities.
Summary of the invention
The objective of the invention is for before the clear-headed nasal trachea cannula to patient and before the operation of diagnosis and treatment of cavum nasopharyngeum deep, sufficient topical anesthesia is carried out in the cavum nasopharyngeum deep, with avoid to the cavum nasopharyngeum passage insert in the process of conduit and during operation of diagnosis and treatment the patient produce sense of discomfort and rejection.Increase the liquid outlet of the anaesthetic of some on the basis of existing nasopharyngeal cavity catheter, and be equipped with syringe, jointly form a set of cavum nasopharyngeum anesthesia outfit, make the patient reduce sense of discomfort and rejection when operation, thereby complete smoothly operation.This device can be for clear-headed nasal trachea cannula, also can be for the operation of diagnosis and treatment in cavum nasopharyngeum deep.
The objective of the invention is to be achieved through the following technical solutions.
Cavum nasopharyngeum anesthesia outfit of the present invention (1) consists of cavum nasopharyngeum topical anesthesia conduit (5) and syringe (4), it is characterized in that described cavum nasopharyngeum anesthetic tube (5) is for the nontoxic PVC plastic catheter of hard long arc shape, the internal diameter of described cavum nasopharyngeum topical anesthesia conduit (5) is 2mm, external diameter is 3mm, length is 18cm, be provided with scale value (2) on described cavum nasopharyngeum topical anesthesia conduit, for measuring the degree of depth of inserting cavum nasopharyngeum, be provided with the liquid outlet that 8～10 diameters are 0.1mm (7) on described anesthetic tube (5), described liquid outlet is for making the anaesthetic ejection, described liquid outlet is arranged alternately on the surface of described cavum nasopharyngeum anesthetic tube, the distribution density of described liquid outlet is 1.3～1.6/cm
2described liquid outlet be shaped as circle, the thromboembolism (6) of an end for sealing at cavum nasopharyngeum topical anesthesia conduit, the other end is connected with syringe, described syringe is used for to described cavum nasopharyngeum topical anesthesia tube injection anaesthetic, the disposable sterilized injector that described syringe is 20mL (4).
The inventor gropes to sum up out technique scheme repeatedly by practice, as shown in the figure: product of the present invention have modern design, expense cheap, simple to operate, avoid the characteristics such as cross infection.When wherein conduit adopts the design of endcapped formula thromboembolism to make to operate, intubate is easily convenient, and patient's injury of nasal cavity is reduced; Be provided with scale value on conduit, for measuring the degree of depth of inserting cavum nasopharyngeum; Evenly be provided with the liquid outlet that 8～10 diameters are 0.1mm on conduit, evenly spray for making anaesthetic.
