Description

Powder formula Digestive System Department esophageal administration device

Technical field

This utility model relates to Digestive System Department medical aid material technical field.

Background technology

Digestion is made up of digestive tube and digestive gland two large divisions, it is one of human body Major Systems, in recent years along with the progress of society, rhythm of life is accelerated, ecological deterioration, digestive system disease is particularly outstanding, esophagus is as the important component part of digestive tube, sickness rate also remains high, such as esophagel disease has esophagitis, Mallory-Weiss Syndrome, benign tumor of esophagus etc., because esophagus is in inside of human body, drug administration is for the people suffering from digestive system disease for a long time, ideal effect cannot be reached, to eat liquid or toughness medicine, although through focus, but cannot accurately by the damage journey of medicine according to esophagus.In esophagus, spray into medicine powder, utilize the adhesiveness of medicine powder and water absorption medicine can be attached to affected area, but medicine powder sphere of action when dispenser is large, likely chokes in patient organ.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of powder formula Digestive System Department esophageal administration device, it utilizes the delivery tube being deep into esophagus inside directly to dust agent medicine to affected area, can prevent powder excess diffusion in dispenser process, safe and reliable, dispenser painful is little, and speed is fast.

For solving the problem, the technical scheme that this utility model is taked is: provide a kind of powder formula Digestive System Department esophageal administration device, comprise powder gas mixing chamber, inflator pump, delivery tube; Inflator pump is fixed on outside powder gas mixing chamber, and the outlet side of inflator pump is communicated with air jet pipe; The other end of air jet pipe and the conducting of powder gas mixing chamber inner chamber; Air jet pipe is provided with A switch valve; The inner chamber top of powder gas mixing chamber and delivery tube conducting; The bottom of delivery tube is administration head; The lower end closure of administration head, the sidewall on sealing top evenly has loose medicine hole in a circumferential direction; The inlet end of inflator pump is communicated with recovery tube; Recovery tube adheres to outside delivery tube, and the lower ending opening place of recovery tube extends to the loose medicine hole site of administration head.

Further optimization the technical program, the outlet side of the inflator pump of powder formula Digestive System Department esophageal administration device is also communicated with airway; Airway adheres to the outside of delivery tube, airway is provided with B switch valve; The upper and lower of administration head is all overlapped and is had annular ex-pansion air bag; The lower end of airway is communicated with two annular ex-pansion air bags.

Further optimization the technical program, powder formula Digestive System Department esophageal administration device at powder gas mixing chamber inner chamber, the open communication of air jet pipe has aeration head.

Adopt technique scheme, the beneficial effect produced is: when 1, using, delivery tube is insinuated in esophagus, the direct corresponding lesions position of administration head, medicine powder is inflated pump and blows out dust cloud in powder gas mixing chamber, then medicine dust cloud sprays in the loose medicine hole of administration head through delivery tube, is attached to lesions position, is not recovered pipe sucking-off by the dust cloud adsorbed and turns back in powder gas mixing chamber, both can not choke patient, and have and can make full use of medicine.2, after two annular ex-pansion airbag aerations, administration head is enclosed in one section of esophagus at affected area place, can prevents powder from spreading further, improve the powder adhesive capacity of lesions position.3, aeration head can make air jet pipe give vent to anger more to be uniformly dispersed, and can improve the mixture content of uniformity coefficient that medicine powder mixes with air and powder.

In figure, 1, powder gas mixing chamber; 2, inflator pump; 3, delivery tube; 4, air jet pipe; 5, A switch valve; 6, loose medicine hole; 7, recovery tube; 8, airway; 9, B switch valve; 10, annular ex-pansion air bag; 11, aeration head; 12, administration head.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.

Shown in Fig. 1-2, powder formula Digestive System Department esophageal administration device comprises powder gas mixing chamber 1, inflator pump 2, delivery tube 3; Inflator pump 2 is fixed on outside powder gas mixing chamber 1, and the outlet side of inflator pump 2 is communicated with air jet pipe 4; The other end of air jet pipe 4 and the conducting of powder gas mixing chamber 1 inner chamber; Air jet pipe 4 is provided with A switch valve 5; The inner chamber top of powder gas mixing chamber 1 and delivery tube 3 conducting; The bottom of delivery tube 3 is administration 12; The lower end closure of administration 12, the sidewall on sealing top evenly has loose medicine hole 6 in a circumferential direction; The inlet end of inflator pump 2 is communicated with recovery tube 7; Recovery tube 7 adheres to outside delivery tube 3, and the lower ending opening place of recovery tube 7 extends to the position, loose medicine hole 6 of administration 12; The outlet side of inflator pump 2 is also communicated with airway 8; Airway 8 adheres to the outside of delivery tube 3, airway 8 is provided with B switch valve 9; The upper and lower of administration 12 is all overlapped and is had annular ex-pansion air bag 10; The lower end of airway 8 is communicated with two annular ex-pansion air bags 10; At powder gas mixing chamber 1 inner chamber, the open communication of air jet pipe 4 has aeration head 11.

The present embodiment in use, first in powder gas mixing chamber, put into appropriate medicine powder, then go out according to the location position of focus the degree of depth that delivery tube 3 probes into, then delivery tube 3 is sent into the esophagus of patient, probe into the degree of depth according to what demarcate, make an administration 12 arrival lesions position.

After administration 12 puts in place, first A switch valve 5 is closed, open B switch valve 9, open inflator pump 2, now inflator pump 2 is to two annular ex-pansion air bag 10 inflating pressures, after pulling delivery tube 4 no longer mobile, close B switch valve 9 and inflator pump 2, now annular ex-pansion air bag 10 is in lesions position isolation place independently space.
