Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a shadowless lamp with an environmental hygiene monitoring sampling specification plate function. Background Technology
[0002] Environmental hygiene sampling is a crucial step in hospital infection control and a fundamental aspect of the process. Through scientific monitoring and analysis, precise control can be achieved, thereby ensuring medical quality and patient safety. Currently, the common clinical practice in hospitals involves using a combination of standardized sampling plates and cotton swabs for environmental hygiene sampling. A standard sterile sampling plate is placed on the area to be sampled to define the sampling area. A cotton swab is then used to evenly swab the sample five times horizontally and five times vertically within the defined sampling area. The swab is then rotated, and the portion that came into contact with the hand is cut off. The remaining portion is placed in a test tube containing a sterile eluent containing a neutralizing agent and immediately sent for testing. This completes the environmental hygiene sampling and testing process.
[0003] However, existing standardized sampling plates require high-temperature, high-pressure sterilization (HTSA) before use when assisting in environmental hygiene sampling. While this ensures the sterility of the samples, it also introduces certain shortcomings and problems. First, HTSA not only increases additional costs but also the workload of the supply room. Since clinical departments select environmental hygiene monitoring at different times, the additional HTSA process leads to delays in the timely turnover of the standardized plates. Second, during the auxiliary monitoring using standardized plates, clinical practice often requires sterilization by burning the plates with an alcohol lamp. Because the plates have a small handle, this burning sterilization process is inconvenient, posing a risk of burns and potential contamination during sampling due to improper sterilization, hindering effective monitoring.
[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a shadowless lamp with the function of an environmental hygiene monitoring sampling specification board, which can realize non-contact definition of sampling area to facilitate safe implementation of environmental hygiene sampling and monitoring operations, effectively reduce costs and workload and potential safety hazards.
[0006] To achieve the above objectives, this utility model employs the following technical solution:
[0007] A shadowless lamp with the function of an environmental hygiene monitoring sampling specification board includes a support structure disposed on one side of a sampling platform; a connecting structure is provided on the top of the support structure, with one end of the connecting structure extending above the sampling platform; a projector is provided on the connecting structure at the end away from the support structure for projecting illumination onto a corresponding area of the sampling platform to define the sampling area without contact. An anti-slip pad is fitted onto the bottom of the base for securing the base to the ground.
[0008] Preferably, the support structure includes a base for placement on the ground, a longitudinal telescopic rod connected to the connecting structure is provided on the top of the base, and the distance between the connecting structure and the projector and the sampling platform is adjusted by the longitudinal telescopic rod. A scale line for measuring the projection height of the projector is also provided on the longitudinal telescopic rod.
[0009] Preferably, the connection structure includes a transverse telescopic rod disposed on the top of the longitudinal telescopic rod via a damping pivot, and a sleeve that engages with the projector is provided at one end of the transverse telescopic rod away from the damping pivot.
[0010] Preferably, the projector includes an embedded projection lamp that is fitted into the sleeve and the irradiation end of the embedded projection lamp is arranged downwards, and a projection port for defining the irradiation projection size to define the sampling area of the sampling stage is provided on the irradiation end of the embedded projection lamp.
[0011] Preferably, the projection port is provided with several projection ports of different models according to its opening size. Each projection port is detachably connected to the illumination end of the embedded projection lamp so as to select the appropriate projection port according to the height of the embedded projection lamp, thereby ensuring the consistency of the sampling area under different projection heights.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0018] Please see Figure 1As shown, this embodiment provides a shadowless lamp with the function of an environmental hygiene monitoring sampling specification board, including a support structure 1 disposed on one side of the sampling platform; a connecting structure 2 is provided on the top of the support structure 1, and one end of the connecting structure 2 extends above the sampling platform; a projector 3 is provided on the connecting structure 2 at the end away from the support structure 1 for projecting illumination onto a corresponding area of the sampling platform to define the sampling area without contact. An anti-slip pad 4 is fitted on the bottom of the base 11 for stably placing the base 11 on the ground. During use, when environmental hygiene monitoring sampling is required on a large, flat surface or skin / mucous membrane placed on the sampling platform with a high bacterial count, the anti-slip pad 4 provides a non-slip constraint. The supporting structure 1 then securely places the connecting structure 2 and the projector 3 on one side of the sampling platform. Adjusting the movable end of the supporting structure 1 as needed moves the connecting structure 2 and the projector 3 up and down to the appropriate position, thus adjusting the projection height of the projector 3. Then, pushing the movable end of the connecting structure 2 moves the projector 3 relative to the supporting structure 1 to adjust it to the appropriate position, thereby allowing the projector 3 to project. Located at a predetermined position above the sampling platform, the projector 3 can be activated to project light onto the predetermined area of the sampling platform, thus defining the sampling area without contact. By using the projector 3 instead of the traditional standard board, the sampling area can be defined without contact. Since the standard board is not used, the high-temperature sterilization process is effectively reduced, which lowers costs and reduces the workload of the hospital supply room. At the same time, it avoids the safety hazards that need to be sterilized by burning the standard board during sampling and monitoring. It can safely carry out environmental hygiene sampling and monitoring operations on large, flat object surfaces or skin and mucous membranes with high bacterial content.
[0019] In this embodiment, the support structure 1 includes a base 11 for placement on the ground. A longitudinal telescopic rod 12, connected to the connecting structure 2, is provided on the top of the base 11. The distance between the connecting structure 2 and the projector 3 and the sampling platform is adjusted via the longitudinal telescopic rod 12. A scale line 13 for measuring the projection height of the projector 3 is also provided on the longitudinal telescopic rod 12. During use, as needed, by adjusting the position of the base 11 of the support structure 1 and guiding the height of the scale line 13, the movable end of the longitudinal telescopic rod 12 moves the connecting structure 2 and the projector 3 up and down to an appropriate position, thereby adjusting the projection height of the projector 3 to the appropriate position. Then, the movable end of the connecting structure 2 is pushed to rotate the projector 3 relative to the support structure 1 to adjust it to the appropriate position, thus placing the projector 3 at a predetermined position above the sampling platform. This operation is convenient and reliable.
[0020] In this embodiment, the connecting structure 2 includes a transverse telescopic rod 22 mounted on the top of the longitudinal telescopic rod 12 via a damping pivot 21. A sleeve 23, which engages with the projector 3, is located at one end of the transverse telescopic rod 22 away from the damping pivot 21. During use, with the position of the fixed end of the damping pivot 21 of the connecting structure 2 defined, pushing the transverse telescopic rod 22 causes the sleeve 23 and the projector 3 to rotate relative to the longitudinal telescopic rod 12 of the supporting structure 1 under the damping connection between the movable end of the damping pivot 21 and its fixed end, thus adjusting them to an appropriate position. Then, operating the movable end of the transverse telescopic rod 22 causes the projector 3 to extend and retract together, adjusting the projector 3 to an appropriate position, thereby placing the projector 3 at a predetermined position above the sampling stage. This operation is convenient and reliable.
[0021] In this embodiment, the projector 3 includes an embedded projection lamp 31 that fits into the sleeve 23, with the irradiation end of the embedded projection lamp 31 facing downwards. A projection port 32 is fitted onto the irradiation end of the embedded projection lamp 31 to define the irradiation projection size and thus define the sampling area of the sampling platform. For example, the projection port 32 has several different models depending on its opening size. Each projection port 32 is detachably connected to the irradiation end of the embedded projection lamp 31 so that the appropriate projection port 32 can be selected according to the height of the embedded projection lamp 31, thereby ensuring the consistency of the sampling area at different projection heights. During use, based on the illumination height requirements of the embedded projection lamp 31 of the projector 3, a corresponding projection port 32 is selected and fitted onto the illumination end of the embedded projection lamp 31. Activating the embedded projection lamp 31 projects light onto the predetermined area of the sampling station, defining the sampling area without contact. This sampling area conforms to the predetermined size standard. The embedded projection lamp 31 and projection port 32 work together to replace the traditional standard plate for non-contact definition of the sampling area. Because it does not use a standard plate, it effectively reduces the steps of high-temperature sterilization, lowering costs and reducing the workload of the hospital supply room. It also avoids the safety hazards associated with burning standard plates during sampling and monitoring. This method can safely conduct environmental hygiene sampling and monitoring operations on large, flat surfaces or skin / mucous membranes with high bacterial counts.
[0022] In specific use of this embodiment, firstly, when it is necessary to conduct environmental hygiene monitoring sampling on a relatively large and flat object surface or skin / mucous membrane with a high bacterial count placed on the sampling platform, the connecting structure 2 and the projector 3 are stably placed on one side of the sampling platform by the support structure 1 under the anti-slip constraint of the anti-slip mat 4; secondly, according to the requirements, under the position limitation of the base 11 of the support structure 1 and the height guidance of the scale line 13, the movable end of the longitudinal telescopic rod 12 is adjusted to drive the connecting structure 2 and the projector 3 to move up and down to the appropriate position, thereby adjusting the projection height of the projector 3 to the appropriate position; then, under the position limitation of the fixed end of the damping shaft 21 of the connecting structure 2, the transverse telescopic rod 22 is pushed to drive the sleeve 23 and the projector 3 to rotate relative to the longitudinal telescopic rod 12 of the support structure 1 under the damping connection between the movable end and the fixed end of the damping shaft 21 to adjust to the appropriate position, and then the movable end of the transverse telescopic rod 22 is operated to drive the projector 3 to extend and retract together to... Adjust the projector 3 to an appropriate position so that it is positioned above the sampling platform, ensuring convenient and reliable operation. Finally, based on the illumination height requirements of the embedded projection lamp 31 of the projector 3, select a corresponding projection port 32 and fit it onto the illumination port of the embedded projection lamp 31. Activate the embedded projection lamp 31 to project light onto the predetermined area of the sampling platform, thus defining the sampling area without contact. This sampling area conforms to the predetermined size standard. The embedded projection lamp 31 and projection port 32, in combination, replace the traditional standard plate to achieve contactless definition of the sampling area. Because it does not use a standard plate, it effectively reduces the steps of high-temperature sterilization, lowering costs and reducing the workload of the hospital supply room. It also avoids the safety hazards associated with burning standard plates during sampling and monitoring. This method can safely conduct environmental hygiene sampling and monitoring on large, flat surfaces or skin / mucous membranes with high bacterial counts.
[0023] In summary, the present invention, with the above-described structure, has the advantages of enabling contactless definition of sampling areas to facilitate safe implementation of environmental hygiene sampling and monitoring operations, effectively reducing costs and workload, and minimizing potential safety hazards.
