Detailed Description
A high-precision rectal administration device is shown in figure 1 and comprises a three-way plug valve 1, wherein a left interface of the three-way plug valve 1 is provided with an injector communicated with the left interface; the upper interface of the three-way plug valve 1 is provided with a pressurizing air bag 2 communicated with the upper interface; three-way plug valve 1's right side interface is provided with rather than intercommunication and right-hand member open-ended dosing pipe 3, is fixed with elastic support ring 4 in the middle part of dosing pipe 3's lateral wall, has seted up a plurality of side medicine outlet 5 for the lateral wall right part of dosing pipe 3.
The three-way plug valve 1 has the structural design that firstly, installation positions are provided for the injector, the pressurizing air bag 2 and the administration tube 3, secondly, the conversion of injection administration and residual liquid medicine propelling two administration operations can be realized, in addition, no vortex is generated in the conversion process, and the liquid medicine cannot be interrupted. The pressurizing air bag 2 generates thrust to the residual liquid medicine through air flow so as to ensure the full injection of the liquid medicine. Elastic support ring 4 can flexibly support in the rectum mucous membrane, reduces the friction between administering tube 3 and the rectum mucous membrane, and then reduces painful sense, guarantees the comfort level of dosing, can prevent to annotate the medicine in-process and deviate from the influence treatment with administering tube 3. The right-hand member export of dosing pipe 3 and side play medicine mouth 5 can be dosed from the multidirection, increase the area of contact of liquid medicine and rectum mucous membrane, when improving the homogeneity of dosing, improve the absorption rate of liquid medicine.
When in use, firstly, the injector filled with the liquid medicine is connected with the left connector of the three-way plug valve 1, the pressurizing air bag 2 is connected with the upper connector of the three-way plug valve 1, and the administration tube 3 is connected with the right connector of the three-way plug valve 1; then slowly insert the rectum with administration tube 3, after administering tube 3 and inserting suitable length, rotate three-way plug valve 1's knob for the syringe communicates with administration tube 3, can begin the injection of liquid medicine, and at this in-process, the liquid medicine flows through syringe, three-way plug valve 1's left interface, three-way plug valve 1's right interface, administration tube 3 in proper order under the thrust of syringe to from administering tube 3's right-hand member export and the side medicine mouth 5 slowly flow out. After the liquid medicine in the syringe has been pushed away, the knob of three-way plug valve 1 is rotated for pressurization gasbag 2 and 3 intercommunications of dosing pipe, and slowly extrude pressurization gasbag 2, produce and promote the air current, under the effect that promotes the air current, the remaining liquid medicine in the dosing pipe 3 slowly flows out from the right-hand member export of dosing pipe 3 and side medicine mouth 5, can realize the whole injection of liquid medicine, overcome current rectum and given the inaccurate, problem of bringing painful sense for the patient easily of dosing pipe dosage.
As shown in FIG. 1, a transparent mounting ring 6 is fitted around the left part of the outer side wall of the administration tube 3, and an annular temperature sensing patch is interposed between the mounting ring 6 and the administration tube 3.
