Description
Technical Field
The application belongs to the technical field of catheter manufacturing, and particularly relates to a full-automatic intelligent induction catheter.
Background
The catheter is a common medical auxiliary instrument, and is required to be inserted in the treatment process of diseases such as internal medicine, surgery, obstetrics and gynecology, pediatrics and the like in the medical field, and can be used for draining urine and can be inserted into the urinary bladder through the urethra of a patient so as to guide the urine to flow out. After the catheter is inserted into the bladder, a balloon is arranged near the head end of the catheter, and the expanded balloon can lead the catheter to be fixedly remained in the bladder and not easy to deviate out, and the drainage part of the catheter is connected with the urine collecting bag to collect urine. The catheter with the structure has the following problems in use: 1. when catheterization operation is carried out, whether the depth of the catheterization tube inserted into the bladder is proper or not directly relates to catheterization effect: too deep insertion, the catheter turns around, folds or tips up in the bladder, the urine cannot be drained completely, and the bladder mucosa is easily damaged; too shallow insertion, the side hole at the front end of the catheter is positioned in the hazy neck or the posterior urethra and is stuck on the mucous membrane layer, which can lead to unsmooth urine drainage and even damage to the urethra. The prior art adopts a method of setting scales on a catheter to solve the problems (such as CN 209630404U), however, the structural improvement is less, the insertion depth of the catheter still needs to depend on subjective judgment of doctors, and the individual differences exist in the lengths and the shapes of the urinary bladder and the urethra of a patient, so that the error probability is easy to exist; 2. the conventional catheter balloon can stimulate the bladder of a patient in the bladder, so that the patient has the feeling of urine at the wanted moment, and if the retention time is longer, the discomfort of the patient is increased and the infection risk is increased; 3. the existing catheter needs to be connected with the urine collecting bag all the time, which causes inconvenience to the dressing and actions of the patient; 4. after the catheter is left for a long time, the urethra of the patient can be loosened, part of urine can flow out from the expanded urethral orifice along the catheter, and clothes and trousers of the patient are polluted; 5. when the urinary catheter is pulled out clinically, the residual urine level is generally measured by using B-ultrasonic, namely, how much urine is in the bladder is measured after the urinary catheter is pulled out and the patient urinates by himself, and the measuring link is measured by using B-ultrasonic, so that the patient is required to go to a hospital specially to do B-ultrasonic, and the time and the labor are wasted.

In addition, it is easy to understand that when the position sensor 2 enters the bladder, the volume of the bladder can be continuously obtained through light detection, the volume is used for judging the volume of the liquid filled in the bladder at a specific moment, and an alarm is sent out when the volume reaches a certain volume, so that the patient is reminded to urinate, and therefore, if the urine collecting bag is required to be kept, the urine collecting bag can be removed if the urine collecting bag is not required, and the position sensor 2 and the alarm component 5 can be taken out to play a role. Correspondingly, the tail end of the catheter body 1 is provided with a connecting part 7 for connecting to a urine collecting bag.
In order to realize automatic reminding of the position, an alarm part 5 is provided. In a preferred embodiment, the alarm part further comprises a microprocessor chip and a buzzer, and the microprocessor chip further comprises: the information extractor is connected with the memory and is used for comparing the light intensity information obtained from the photosensitive component with the corresponding relation information to obtain the current position.
With respect to the preferred embodiment of the data acquisition component 3, the data acquisition component comprises a porous electrolyte substrate and a signal transceiver disposed within the catheter body 1, the porous electrolyte substrate being doped with anode and cathode materials to form anodes and cathodes spaced apart across the gap, urine passing between the cathodes and anodes, the porous electrolyte substrate being absorbent of liquid and producing a flow of signal ions for receipt by the signal transceiver when wetted by the urine. The signal transceiver delivers the relevant signals to the alarm unit 5. Accordingly, the memory in the micro-processing chip in the alarm unit 5 stores normal thresholds regarding the volume of urine discharged, the flow rate, whether the amount of bacteria contained exceeds a critical level, and the mineral level, and alarms upon finding that the normal thresholds are exceeded. In other embodiments, the data acquisition component 3 may be just one sensor or sensor assembly that can generate the monitoring data described above.
The urine volume in the bladder is calculated and recorded in real time by the data acquisition component 3, and the calculated urine volume can be transmitted to the remote network terminal 6 through the data transceiver component, wherein the remote network terminal 6 is preferably a mobile phone APP, and the mobile phone APP records the data and displays the data on an interface. In this way, the urine remained in the bladder can be known in the process of inserting the catheter body 1, and the trouble that the patient needs to do B ultrasonic wave additionally is eliminated.
It will be appreciated that signal transmission means are provided along the inner wall of the catheter body 1, and that the data acquisition means 3, the alarm means 5 are interconnected by means of the signal transmission means and are connected to the position sensor 2. Further, the signal transfer member is a flexible electrode.
The catheter body 1 is made of an extrudable and moldable material, in particular of a silicone, or a silicone blend, or a latex blend, or a polyolefin, such as Polyethylene (PE) or polypropylene (PP), or a copolymer of polyethylene, such as Ethylene Vinyl Acetate (EVA) or polyvinyl chloride (PVC) or polyvinylidene. The various components of the catheter can be made in one piece from the desired materials.
The head end of the catheter body 1 is provided with a balloon 4, in the scheme, the surface of the balloon 4 is provided with a detector for monitoring the width of the balloon, and the detector monitors that the width of the balloon 4 exceeds the width of the urethral orifice and then gives an alarm in the process of filling the balloon 4 after the catheter body 1 is inserted, so that the balloon 4 can be ensured to expand in the minimum volume and cannot fall off.
The main body of the balloon 4 is preferably made of silica gel, and the surface of the balloon 4 is coated with an antibacterial layer, so that the antibacterial and anti-urinary salt-deposition functions are effectively inhibited.
With continued reference to fig. 1, the surface of the catheter body 1 is provided with an attachable absorbent sponge 8, which may be similar to a sanitary towel or a diaper, and the attachment position of the absorbent sponge 8 may be changed according to the needs of the individual, and is typically attached to extend 5-10cm from the urethral orifice to the tail end. For patients with long-term indwelling catheters, part of the patient's urethral orifice can loosen, and part of urine flows out from the urethral orifice along the catheter at this time, so that clothes and trousers of the patient are polluted. In order to prevent urine flowing out carelessly from the urethral orifice from polluting clothes and trousers of a patient and reduce infection risk, the surface of the catheter body 1 is provided with the adhesive water-absorbing sponge 8, and the water-absorbing sponge 8 can be placed and replaced according to the needs of the patient, so that the operation is simple.
