Description

Technical Field

[0001] The utility model relates to the field of incontinence dermatitis prevention, in particular to an incontinence dermatitis prevention device for incontinence patients. Background Art

[0002] Severely ill patients often use antibiotics in large doses for a long time due to infection, which leads to intestinal flora imbalance. In addition, patients need to increase nutrition, and usually choose enteral nutrition preparations, which patients cannot tolerate. Coupled with intestinal flora imbalance, patients suffer from diarrhea, or some patients have impaired consciousness and coma, leading to incontinence and incontinence dermatitis. Many patients have long-term moisture and pressure on the perineum, buttocks, and sacrum, and may even suffer pressure injuries, leading to skin infection and incontinence dermatitis.

[0003] Incontinence dermatitis refers to inflammation of the skin caused by long-term or repeated exposure to urine and feces, accompanied by blisters or skin damage. It is a common complication for incontinence patients and can also cause other diseases such as pain, infection and pressure sores. Today, the prevention and treatment of incontinence dermatitis in incontinence patients is often achieved through the installation of prevention devices. That is, by inserting a catheter in the anus to assist in the drainage of excrement, preventing the excrement from causing moisture to the perineum, buttocks, and sacrum of the incontinent patient, reducing the occurrence of incontinence dermatitis, promoting skin healing, and promoting patient comfort.

[0004] The existing Chinese patent is CN202022207329.9, which is an intra-anal negative pressure drainage tube, including an anal tube, a drainage bottle, and an air pump. One end of the anal tube is provided with a connecting cap, and the anal tube is connected to the upper part of the drainage bottle through the connecting cap, and a sealing gasket is directly provided at the end of the anal tube and the drainage bottle. The upper part of the inner cavity of the drainage bottle is provided with a water-gas separation tube, and the air suction port of the air pump is connected to the water-gas separation tube through a pipe. The outer periphery of the lower part of the drainage bottle is provided with multiple folds, and the folds are wavy. The utility model uses an air pump to extract air in the drainage bottle to form negative pressure, which is used to extract feces from patients with fecal incontinence for drainage. The folds in the flow bottle can contract when the negative pressure is too large to prevent damage to the intestinal wall caused by excessive negative pressure. The water-gas separation tube can separate liquid and other substances to prevent excessive water vapor from being inhaled into the air pump, which affects the service life of the air pump.

[0005] It can be seen from the above patents that for the existing prevention and treatment of incontinence dermatitis, the anal canal or catheter is often used to assist in the drainage of excreta from incontinent patients, but the effect of its use is not sufficient, that is, when the excreta lacks moisture and is dry, it is relatively difficult to be drained out through the anal canal or catheter, resulting in blockage of the excreta drainage, which affects the efficiency of the prevention and treatment of incontinence dermatitis. At the same time, the drainage of excreta is not safe and efficient enough, that is, long-term negative pressure suction can easily cause damage to the intestinal mucosa, causing secondary harm to incontinent patients. Secondly, when the negative pressure pump body performs negative pressure suction activity, the negative pressure inlet end lacks certain protective measures to block water vapor, resulting in water vapor entering the interior of the negative pressure pump body, affecting the service life of the negative pressure pump body.

The limiting strips 92 on the front and back sides of the shell 91 are vertically fixed, and the limiting strips 92 on both sides are rectangular strips. The water absorption plates 93 are equidistantly built into the shell 91 from left to right, and the water absorption plates 93 are equidistantly installed along the inside of the shell 91 in a state of three on top and two on the bottom, and adjacent There is a distance between the water absorption plates 93, and a supporting frame 94 is connected to the lower end of the shell 91 and the inner side wall of the shell 91, and the supporting frame 94 is arranged in a concave frame shape as a whole, so that the shell 91 can be positioned and plugged in through the supporting frame 94 to ensure the accurate installation position of the water vapor adsorption structure.

[0038] The working steps of the device are as follows;

[0039] S1: Insertion. Insert the disposable catheter 4 from the patient's anus and insert the disposable catheter 4 5-7 cm according to the scale set at the lower left end of the disposable catheter 4 to avoid inserting it too long or too short. After the disposable catheter 4 is inserted, the adsorption end 5 connected to the bottom left of the disposable catheter 4 can be synchronously moved into the patient's anus. Then, through the regulating valve 2 on the front side of the three-way pipe body 1, the three outlet ends of the three-way pipe body 1 can be intermittently adjusted to close, so that stable intermittent negative pressure adsorption or intermittent flushing activities can be achieved subsequently.

[0040] S2: Inflation reinforcement. After the disposable catheter 4 is accurately placed, the inflation pipe 72 inside the inflation component 7 can be connected to the external inflation device, and the external inflation device can be used to perform inflation activities, so that the gas is guided along the inflation pipe 72, the inflation head 71 and the air guide tube 73 in turn to the inside of the airbag 74, so that the airbag 74 expands. As the airbag 74 expands, it can fit tightly against the patient's anus, reducing the occurrence of the disposable catheter 4 falling off, so that the advantage of strengthening the firmness of the disposable catheter 4 is achieved.

[0041] S3: Negative pressure extraction. When it is necessary to extract the patient's excrement, the negative pressure device connected to the external pipe 84 inside the negative pressure component 8 can be operated to perform negative pressure adsorption. The negative pressure pipe 81 connected to the right side of the three-way pipe body 1 can be combined with the disposable catheter 4 to suck the excrement into the disposable catheter 4, the connecting pipe 3, the three-way pipe body 1 and the negative pressure pipe 81. Finally, along the liquid inlet pipe 82 connected to the right side of the negative pressure pipe 81, it is drained into the drainage box 83 to achieve negative pressure adsorption and storage of excrement, thereby preventing the excrement generated by incontinent patients from being exposed to long-term moisture or pressure on the perineum, buttocks, and sacrum, causing skin damage and inflammation.

[0042] When it is necessary to process the excreta inside the drainage box 83, the sealing cover 85 sealed at the upper end of the drainage box 83 can be pulled up to release the seal of the sealing cover 85 on the upper end of the drainage box, and the connection between the negative pressure tube 81 and the liquid inlet 82 and the connection between the external tube 84 and the external negative pressure device can be disconnected in sequence. In this way, the medical staff can process the excreta collected in the drainage box 83 through the opened drainage box 83;

[0043] The negative pressure suction time should not be too long. Generally, the negative pressure suction time is 10 minutes. At the same time, the negative pressure value is set between 0.02-0.04Mpa to avoid the negative pressure suction process causing intestinal mucosal damage and bleeding.

[0044] If fresh blood is drawn out during the negative pressure suction process, the negative pressure suction activity should be stopped immediately, and the disposable catheter 4 should be pulled out once and for all, and protective agents or drugs should be used for treatment to avoid damage to the intestinal mucosa of the incontinent patient, thereby achieving negative pressure suction coordination and realizing the convenient discharge of excrement produced by the incontinent patient.

[0045] S4: Flushing. If the excrement produced by the incontinent patient is dry and cannot be discharged smoothly, the flushing component 6 provided at the upper end of the three-way pipe body 1 can be used to inject and flush the saline solution. First, the regulating valve 2 on the front side of the three-way pipe body 1 is turned to achieve the connection between the saline catheter 61 and the disposable catheter 4. Then, the saline catheter 61 connected to the external saline bag or the saline storage place can guide the saline solution to the water inlet end 62, and then introduce it into the interior of the three-way pipe body 1 through the threaded head 63. Finally, it enters the disposable catheter 4 through the left end of the three-way pipe body 1, so that the saline solution enters the patient's anus from the suction end 5 provided at the lower left end of the disposable catheter 4 to flush and dilute the excrement inside the patient's anus, ensuring the rapid negative pressure discharge of the subsequent diluted excrement, thereby realizing auxiliary flushing of excrement and accelerating the efficiency of subsequent negative pressure discharge.

[0046] S5: Water vapor protection. When the negative pressure device connected to the negative pressure assembly 8 is in operation, the inhaled gas will enter the shell 91 inside the water absorption assembly 9, causing the water vapor to sequentially contact the five water absorption plates 93 installed at equal intervals (three at the top and two at the bottom) inside the shell 91, thereby achieving auxiliary absorption of water vapor and preventing water vapor from directly entering the external negative pressure device and affecting the service life of the negative pressure device.

[0047] When the five water absorption plates 93 absorb a certain amount of water vapor and need to be replaced, the knobs 963 of the locking structure 96 provided at the upper ends of the front and rear sides of the receiving frame 94 can be rotated respectively, so that the knobs 963 correspondingly drive the locking plates 962 fastened to the bottom to rotate 90 degrees. In this way, the locking plates 962, which were originally locked in a cross-intersection with the locking grooves 965 provided on the connecting plate 964, are rotated to be parallel to the locking grooves 965 in the upper and lower longitudinal directions, thereby releasing the locking. When the other locking plates 962 are also rotated and unlocked, the shell 91 can be directly pulled up to remove the shell 91 from the inside of the receiving frame 94 for replacement.

[0048] When installing the new shell 91, first, the shell 91 is vertically fastened to the limit strips 92 on the front and rear sides to be plugged into the limit slots 95 vertically opened inside the front and rear sides of the receiving frame 94 to achieve the positioning and placement of the shell 91. At the same time, the connecting plate 964 fastened to the side of the limit strip 92 will then abut against the upper end of the receiving frame 94, so that the opened locking slot 965 passes through the positioning column 961 in advance. For this reason, the locking plate 962 will be at the upper end of the locking slot 965. Therefore, the knob 963 can be manually rotated again to make the locking plate 962 and the locking slot 965 re-form a cross-locking state to quickly complete the positioning, installation and use of the new shell 91, thereby achieving the advantages of negative pressure water vapor assisted absorption treatment and ensuring the service life of the external negative pressure equipment.

[0049] The present invention provides a device for preventing incontinence dermatitis for incontinent patients. The device is provided with a flushing component 6, which can guide the excreta through a physiological saline catheter 61 after the excreta is negatively adsorbed, so as to achieve flushing and cleaning. The device is also provided with an inflation component 7, that is, after the disposable catheter 4 is inserted into the patient's anus, the air bag 74 can be inflated to improve the connection firmness and reduce the slippage phenomenon. The device is also provided with a negative pressure component 8, that is, a negative pressure device connected to an external pipe 84, which can collect the excreta under negative pressure into the drainage box 83 to prevent the excreta from causing infection to the patient's anus. Secondly, the device is provided with a water absorption component 9, that is, a water absorption plate 93 provided inside the shell 91, which can absorb and process the water vapor inside the negative pressure air to prevent the water vapor from affecting the negative pressure device. At the same time, the device is provided with a locking structure 96 provided before and after the receiving frame 94, so that the shell 91 can be quickly disassembled, assembled and replaced.
