Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary devices, in particular to a sampling device for monitoring hand hygiene. Background Art

[0002] Hospital infection is the focus of public health today. Catheter-related bloodstream infection (CRBSI) is an important type of infection, and hand cleaning and disinfection is one of the most basic, simplest and most important measures to reduce catheter-related bloodstream infection (CRBSI). However, although the importance of hand hygiene has been widely recognized, the actual implementation is not ideal. Relevant studies have shown that nurses often fail to meet the expected standards when performing hand hygiene, which not only increases the risk of hospital infection but also poses a threat to patient safety. Nurses may adopt incorrect methods or ignore certain key steps when performing hand hygiene due to weak hand hygiene awareness, lack of adequate training or untimely monitoring of nurses' hand hygiene. Therefore, improving the compliance and correctness of nurses' hand hygiene and effectively testing the effectiveness of hand hygiene disinfection are of great significance to reducing the rate of hospital infection.

[0003] At present, the method for monitoring the effectiveness of hand hygiene in my country is WS / T 313-2019 "Hand Hygiene Standards for Medical Staff". Among them, the main method used for sampling and monitoring the effectiveness of hand hygiene disinfection is the cotton swab sampling pouring plate method. The main problems are: 1. Put five fingers together and use cotton swabs to smear the sampling area of ​​about 30cm2. The disadvantage is that the sampling area is inaccurate; 2. The cotton swab is smeared from the heel to the fingertip twice for sampling. The disadvantage is that different people take samples, and the sampling time and intensity are different. For the hand hygiene compliance detection method, the direct observation method is mainly used. The main problems are: in daily medical care activities, when the observation object is not informed, the observation object is randomly selected by professionally trained observers to observe and record the timing and implementation of hand hygiene of medical staff. The disadvantage is that the workload of the observer is large and the whole process is very time-consuming. It takes a lot of time and energy to train professional and qualified observers. The recording results of the observers have selection bias, Hawthorne effect and observer bias. Utility Model Content

[0016] The box cover is provided with a box cover handle;

[0017] The specific structure of the disinfectant holder is as follows:

[0018] The disinfectant bottle fixing frame is fixedly installed on the outer side of the box body, and a weighing sensor is installed at the bottom of the disinfectant bottle fixing frame;

[0019] The pressure sensor, electric drive device, turntable control button are electrically connected to the timing processing unit, and the weighing sensor, display screen and timing processing unit are electrically connected to the weighing processing unit, wherein the timing processing unit is used to send instructions to the electric drive device.

[0020] The method of using the utility model device is:

[0021] Preparatory measures:

[0022] 1. Open the lid of the sampling box, place multiple sampling components one by one in the sampling component slots of the turntable, and then close the lid; when placing the sampling components in the sampling component slots below the finger enclosure frame, it is necessary to press the turntable control button once, so that the timing processing unit outputs an instruction to notify the electric drive device to drive the turntable to rotate through a preset angle, so that the sampling component slots below the finger enclosure frame are rotated out of the blocking range of the finger enclosure frame;

[0023] 2. Place the hand sanitizer bottle in the sanitizer bottle fixing frame. The weighing sensor transmits the sensor signal to the weighing processing unit for processing, records the initial weight of the sanitizer, and displays it on the display screen.

[0024] Operation process:

[0025] 1. Open the sampling door of the closed finger enclosure frame;

[0026] 2. When the nursing staff washes their hands, they press the disinfectant. At this time, the weighing sensor under the disinfectant bottle fixing frame transmits the sudden sensor signal to the weighing processing unit;

[0027] 3. After calculating and processing the sensor signal, the weighing processing unit outputs the corresponding signal to the timing processing unit, and the timing processing unit records the start time of hand washing;

[0028] 4. After washing hands, the nursing staff extends their fingers into the finger sampling area in the finger enclosure frame through the open sampling door, and presses the disposable sampling diaphragm in the sampling assembly with their fingers. At this time, the piston plate and piston connecting rod under the disposable sampling diaphragm move downward, pressing the pressure sensor, and the pressure sensor transmits the output signal to the timing processing unit for calculation and processing;

[0029] 5. When the pressure is greater than a preset pressure value, the timing processing unit records the end time of hand washing, subtracts the start time of hand washing, obtains the duration of this hand washing and records it, and records the start to end of this hand washing as the number of hand washings; when the pressure is continuously greater than the preset pressure value and maintains a preset time length, such as more than 5 seconds, from the end time of hand washing, the timing processing unit sends a command to the electric drive device, and the electric drive device drives the turntable to rotate through the shaft, and at the same time the nursing staff lifts the finger, the piston plate and the piston connecting rod reset upward under the action of the spring, and the bottom surface of the piston connecting rod is out of contact with the pressure sensor; when the turntable rotates through a preset angle, it stops automatically, so that the next sampling component rotates to the position directly below the finger enclosure frame, and the timing stops; the timing processing unit transmits the above-mentioned information on the duration of this hand washing and the number of hand washings to the weighing processing unit, and displays it on the display screen through the weighing processing unit;

[0030] 6. Close the sampling door to complete the hand hygiene and sampling. The nursing staff can now perform other operations;

[0031] 7. When the nursing staff performs hand hygiene and sampling again, repeat steps 1 to 6;

[0032] 8. After the nursing staff completes all operations, the recorder can record the final weight of the hand washing disinfectant on the display screen, and subtract it from the initial weight of the hand washing disinfectant to get the amount of disinfectant used. The number of hand washings and the duration of each hand washing can also be obtained from the display screen, and the disposable sampling membrane can be taken out for bacterial culture, and the hand hygiene disinfection effect can be evaluated based on the bacterial culture results.

[0033] Furthermore, the number of the sampling components and sampling component slots is 8.

[0034] In this case, the electric drive device drives the turntable to rotate by a preset angle of 45 degrees each time.

[0035] Furthermore, the sampling component also includes a diaphragm fixing part nested inside the sampling component frame. The diaphragm fixing part is a frame-shaped fixing part, which is pressed on the disposable sampling diaphragm. The outer wall of the diaphragm fixing part is attached to the inner wall of the sampling component frame. At this time, a finger passes through the middle of the diaphragm fixing part to press the disposable sampling diaphragm.

[0036] In this way, the diaphragm fixing piece can firmly press the disposable sampling diaphragm so that the disposable sampling diaphragm will not be moved upward by fingers.

[0037] Furthermore, the device also includes a cover plate that can be placed horizontally on the sampling component, the edge of the cover plate has a cover plate notch that is engaged with the finger enclosure frame, and a cover plate handle is fixedly provided on the top of the cover plate.

[0038] In this way, when in use, after all sampling components are placed, the cover is placed on the sampling components, and the notch of the cover is engaged with the finger enclosure frame, which can protect the unsampled and sampled disposable sampling membranes and prevent them from being contaminated by microorganisms in the air and causing sampling errors, thereby better ensuring the evaluation of hand hygiene and disinfection effects.

[0039] Furthermore, the top plate of the finger enclosure frame is made of transparent material, and the box cover is also provided with a hinged observation door, the observation door faces the top plate, and a handle is installed on the observation door.

[0040] In this way, when the finger is inserted into the finger enclosure frame for sampling operation, the observation door can be opened. Since the top plate of the finger enclosure frame is transparent, it can be conveniently observed from above, which facilitates smoother operation.

[0041] Furthermore, an ultraviolet lamp is fixedly mounted on the upper inner wall of the sampling mechanism area, and an ultraviolet lamp switch button is also provided on the box cover. The ultraviolet lamp is electrically connected to the battery unit via the ultraviolet lamp switch button.

[0042] In this way, after all sampling components are placed, ultraviolet light can be used to irradiate and disinfect the inside of the sampling mechanism area to reduce internal contamination and better ensure the evaluation of hand hygiene and disinfection effects.

[0043] Furthermore, a main power switch button is also provided on the box cover, and each electrical device is electrically connected to the battery unit via the main power switch button.

[0044] When the device is not in use, the power supply to all electrical devices can be cut off by simply turning off the main power switch button, which makes it easier to control the power on and off of each electrical device and reduces battery consumption.

[0045] The beneficial effects of the utility model are:

[0046] The amount of hand sanitizer used in nursing operations can be monitored, the number of hand washes and the duration of each hand wash can be recorded, and the effect of hand hygiene and disinfection can be evaluated by taking out the disposable sampling membrane for bacterial culture, thereby realizing semi-automatic monitoring of nursing operations.
