A two-cavity catheter with a bag comprises two inner cavities, a medicine injecting opening, a gas injection opening, a gas bag and a medicine outlet spray hole. A two-cavity catheter without a bag comprises two inner cavities, a medicine injecting opening, a liquid outlet, a liquid inlet and a medicine outlet spray hole. A three cavities catheter with a bag comprises three inner cavities, a medicine injecting opening, a gas injecting opening, a liquid outlet, an air bag, a liquid inlet and a medicine outlet spray hole. The utility model enables the medicine liquid to be sprayed on the corresponding position in a vaporous state to obtain the functions of improving treating effect, reducing side action, saving medicine, etc. The utility model is suitable for the treatment of the medicine feeding by spraying or aerial fogging in the cavity or the tube of a human body.
Description
This utility model belongs to technical field of medical instruments, is specifically related to a kind of spray delivery conduit, relates to spray in a kind of human pipeline of being used for, body cavity or the deep tissue internal organs conduit of vaporific medicinal liquid more precisely.
In the existing clinical treatment technology, existing diagnosis and the treatment of adopting conduit injection carrying out some diseases is as drug-injection in treatment, the treatment of the local spray of gastrointestinal mirror lower digestive tract medicine etc. in the trachea under the fibre bronchus mirror.But the conduit of using in the above-mentioned treatment is common injection catheter, and its medicine outlet bore is big, and it is vaporific that the medicinal liquid that outpours is not, therefore come with some shortcomings, as: 1, under the fibre bronchus mirror in the trachea during drug-injection in treatment: 1. the amount of liquid of Zhu Ruing is limited, the drug level height, zest is big, easily has side effects; 2. medicinal liquid is subjected to gravity effect to flow to the bronchus and the lung of low level, and promptly the drug distribution inequality affects the treatment; 3. may cause the part pulmonary atelectasis; 2, during the treatment of the local spray of gastrointestinal mirror lower digestive tract medicine, medicinal liquid ejection back is owing to be subjected to gravity effect to flow to lower, waste medicine and affect the treatment etc.
The purpose of this utility model is that a kind of spray delivery conduit will be provided, can obviously reduce the particle diameter of institute's spraying liquid, increase the absorption area of medicinal liquid, medicine is evenly distributed fast, is subjected to gravity effect less, thereby reach effects such as improving therapeutic effect, minimizing side effect, saving medicine.
The purpose of this utility model realizes by following technical proposal: described spray delivery conduit, but but be not have the air bag injection catheter originally or have the medicine outlet of air bag injection catheter to be designed to one or more small drug spray-hole, obviously reduce the gross area of medicine outlet, medicinal liquid is injected after small drug spray-hole ejection by medicine-pouring port, be cut into small vaporific focus and the corresponding site of being sprayed on, thereby make the medicinal liquid uniform distribution, and reduce medicinal liquid and be subjected to gravity effect to flow to lower, reach and improve therapeutic effect, reduce side effect, save effect such as medicine.
Below in conjunction with figure this utility model is elaborated:
