Description

Device for assisting patient in urination after operation

Technical Field

The invention relates to a medical instrument, in particular to a device for assisting a patient in urination after a surgery.

Background

Anesthesia technique is an indispensable important technique in modern clinical surgical treatment, and brings a series of problems such as anesthesia accident, postoperative vomiting, postoperative urinary retention and the like while allowing patients to receive surgical operation without pain. Among them, postoperative urinary retention is a very common postoperative complication of general anesthesia. Urinary retention refers to the condition that the bladder is full of urine and cannot be discharged normally. The typical manifestations are that the bladder is suddenly filled with urine and can not be discharged due to various reasons, so that the patient is very painful and needs emergency treatment frequently. The control and regulation of the human body to various sensory nerves and bladder smooth muscle after general anesthesia require a period of adaptation. Meanwhile, patients after general anesthesia often need to lie in bed for rest, and need to relieve themselves on the sick bed, so that many patients cannot smoothly go on due to the fact that the patients cannot adapt to the change of defecation and defecation modes. Therefore, urinary retention often occurs in many patients after general anesthesia, and the number of operations in the lower abdominal inguinal region, such as inguinal hernia disease, pelvic bone fracture, bladder cancer, etc., has been increasing year by year as the population ages. Such procedures or procedures are closely related to the control of the relevant tissues such as bladder muscles and nerves. The post-operative urinary retention of these post-operative patients is more likely than that of conventional general anesthesia patients and becomes a clinically non-negligible problem. In addition, with the increase of age, the elderly men often have the inevitable occurrence of prostatic hyperplasia and prostatic hypertrophy, and frequent urination and difficult urination of the patients are also common problems in clinic. The most direct and effective means for solving the postoperative urinary retention is to perform urethral catheterization. Namely, the silicone tube is inserted into the urethral orifice and is directly placed into the bladder through the urethra, and the urine is led out of the body by utilizing the basic principle of 'water flowing to the lower part'. However, the process of placing the catheter and the indwelling catheter often bring great pain and psychological dissimilarity to the patient, and more importantly, the urethral catheterization belongs to invasive operation in medicine, the urethra is easy to be damaged during catheterization, bacterial proliferation is easy to cause infection after long-term catheterization, the urethra is damaged and bleeds due to catheterization, and the autonomous urination is still difficult. Therefore, in clinical work, doctors generally recommend that patients urinate through external auxiliary means, and only when the patients still can not urinate for a long time or the patients are extremely painful, the doctors recommend urethral catheterization. Three common external auxiliary means are provided, the first is that the bladder smooth muscle and the detrusor muscle are relaxed by hot compress on the bladder of the patient so as to assist the patient in urination; the second is that the bladder of the patient is pressed, so that the pressure in the bladder is higher in the extrusion period, and the stimulation to sensory nerves is increased, thereby arousing stronger micturition reflex to assist the patient in micturition; the third is to play water or "hiss" to the patient to make psychological cues to induce the patient to urinate. The three common clinical means have been widely proven to be effective and practical, but the three ways are implemented manually, and due to shortage of medical care personnel, the medical care personnel usually operate and demonstrate the accompanying personnel and then operate the accompanying personnel to assist the patient in urination. However, the accompanying person is not in a standard operation, the hand hygiene is not well kept, various conditions are limited, and the like, so that the auxiliary patient still cannot urinate well, and a plurality of patients finally need to urinate by inserting the tube, and related clinical risks are increased. Therefore, there is a need to solve this problem in a more scientific and mechanized way.
