Abstract:

This study introduced the structure of the rectal powder injection device. A total of 100 patients with mixed hemorrhoids in our hospital were recruited randomly from January to October 2019. These patients were divided into the experimental group（n=50） and the control group（n=50）. Patients in the experimental group received the medication through the new designed device. Patients in the control group received the medication through smearing. The study showed that the new device could administer the powder to patients,save the cost of changing dressings,and reduce the number of days in hospital（P<0.05）. The device is worthy of clinical promotion.
