Description

Technical Field

[0001] The invention relates to the technical field of postoperative dressing change, in particular to a dressing change device used for mixed hemorrhoid surgery. Background Art

[0002] Hemorrhoids are the anorectal disease with the highest incidence rate. Mixed hemorrhoids refer to the varicose venous plexus of internal and external hemorrhoids that cross the upper and lower dentate line. They communicate and anastomose with each other, so that the internal and external hemorrhoids form a whole. Clinically, it is recommended that patients with stage I to III mixed hemorrhoids and stage IV mixed hemorrhoids who are ineffective with conservative treatment and instrumental treatment should take surgical treatment. Each surgical method has different indications. External resection and internal ligation of mixed hemorrhoids is the preferred surgical method.

[0003] After surgery, the perianal area is often accompanied by local lymphatic and blood circulation disorders and inflammatory exudation, resulting in complications such as perianal pain and edema. The dressing change of the postoperative incision wound is a key link affecting wound healing, which will directly affect the recovery process after mixed hemorrhoid surgery. In the existing dressing change process, the site is mostly manually smeared with a sterile cotton ball, which is not convenient for the liquid to fully cover the incision wound position. In addition, the sterile cotton ball is in multiple contact with the patient's postoperative incision wound after mixed hemorrhoid surgery, which increases the risk of repeated pain stimulation of the incision wound and causes wound tearing. Therefore, in view of the above problems, a dressing change device for mixed hemorrhoid surgery is proposed. Summary of the invention

[0016] Step 2: clean the patient's anus and the area near the anus, insert the internal hemorrhoid dressing module and the shaping support component into the patient's anus, so that the splash-proof flexible component covers the external hemorrhoid incision position and fits the patient's buttocks;

[0017] Step 3: The drug liquid is injected into the outer drug liquid inlet and outlet groove by the drug liquid injection pipe and flows upward to the external hemorrhoid incision for dressing change; the drug liquid delivery component delivers the drug liquid and discharges it from the shallow drug outlet groove and the deep drug outlet groove;

[0018] Step 4: The external hemorrhoid dressing module receives and circulates the liquid medicine.

[0019] Compared with the prior art, in the present invention, the internal hemorrhoid dressing change module and the external hemorrhoid dressing change module are used to replace the medicine solution on the internal hemorrhoid incision wound and the external hemorrhoid incision wound of the patient after mixed hemorrhoid surgery respectively, and the dressing of the incision wound is changed by delivering the medicine solution as the medicine solution is injected, thereby reducing the repeated pain stimulation of the incision wound during the dressing change and reducing the risk of tearing of the incision wound during the dressing change.

[0020] Compared with the prior art, in the present invention, during the process of changing the dressing on the postoperative incision wound in the patient's body, the shaping support component supports and shapes the area around the postoperative incision wound, thereby reducing the degree of stimulation caused by direct contact between the postoperative incision wound and the device. During the process of changing the dressing with the liquid medicine, the risk of repeated contact and tearing of the postoperative incision wound, which affects recovery, is reduced.

[0021] Compared with the prior art, in the present invention, the top surface of the external hemorrhoid dressing module with a concave spherical surface can also collect the medicine liquid. The concentrated medicine liquid is convenient for keeping the patient's external hemorrhoid incision wound in a moist environment, ensuring that the patient's external hemorrhoid incision wound is fully in contact with the medicine liquid for dressing change. After the medicine liquid injection pipe is sealed, the medicine liquid concentrated on the top surface of the external hemorrhoid dressing module will be re-delivered to the patient's internal hemorrhoid incision wound by the medicine liquid delivery component, realizing the circulation of the medicine liquid and ensuring that the medicine liquid is in repeated contact with the patient's internal and external incision wounds.

[0037] It should be noted that the use process of the dressing change device for mixed hemorrhoid surgery provided by the present invention includes the following steps: first, the patient's anus and nearby parts are cleaned, and then the position of the patient's postoperative incision wound is determined, and the internal hemorrhoid dressing change component 1 is placed into the patient's anus. At this time, the splash-proof flexible component 4 covers the incision wound position of the patient's external hemorrhoids, and then the splash-proof flexible component 4 is fitted with the patient's buttocks, and the liquid medicine is injected through the liquid medicine injection pipe 12, so that the liquid medicine enters the outer liquid medicine inlet and outlet groove 13 on the inner side of the external hemorrhoid dressing change module 2 along the liquid medicine injection pipe 12, and as the liquid medicine is injected, the liquid medicine will flow from the through hole at the top of the outer liquid medicine inlet and outlet groove 13 to the patient. The postoperative incision wound on the outer side of the anus is transported so that the medicine contacts the postoperative incision wound on the outer side of the anus of the patient. As the injection of the medicine increases, the medicine gathers at the top of the external hemorrhoid dressing module 2 to fumigate the postoperative incision wound of the patient, thereby changing the dressing of the postoperative incision wound on the patient's external hemorrhoids. The medicine delivery pump in the medicine delivery component 8 is started, and the medicine delivery pump transports the medicine in the outer layer medicine inlet and outlet groove 13 to make the medicine flow to the medicine outlet connecting groove 9 and the deep medicine outlet groove 11. Then, as the medicine is continuously transported, the medicine enters the patient's body from the shallow medicine outlet groove 10 and the branch at the top of the deep medicine outlet groove 11, so that the medicine contacts the patient's postoperative incision for dressing change.
