Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hand disinfection monitoring, in particular to a clinical hand disinfection testing structure. Background Art
[0002] Hand disinfection is a key link in preventing hospital-acquired infections and ensuring the safety of patients and medical staff. According to the "Medical Staff Hand Hygiene Standards", there are strict standards for the total bacterial colony counts of sanitary hand disinfection and surgical hand disinfection. The total bacterial colony counts monitored for sanitary hand disinfection should be ≤10cfu / cm2, while the total bacterial colony counts monitored for surgical hand disinfection should be ≤5cfu / cm2.
[0003] Due to the complexity of the hand skin area, according to the current hand disinfection monitoring and sampling method, a single cotton swab is used to rub each area of both hands. Not only does it take a long time to rub and have a slow sampling efficiency, but it may also cause omissions in the rubbing due to human factors, resulting in incomplete sampling, errors in the test results and the actual situation, and an increased risk of cross-infection in the hospital. Utility Model Content
[0004] The utility model aims at the technical problems existing in the prior art and provides a clinical hand disinfection inspection structure to solve the problem that according to the current hand disinfection monitoring sampling method, a single cotton swab is used to rub the areas of both hands one by one, which not only takes a long time to rub and has a slow sampling efficiency, but also may cause omissions in rubbing due to human factors, resulting in inadequate rubbing.
[0005] The utility model solves the above technical problems with the following technical solutions: a clinical hand disinfection inspection structure, comprising:
[0006] Machine;
[0007] A lower mold, the lower mold is arranged on the top of the machine platform, wherein the lower mold is made of a flexible material, and two receiving grooves 1 in the shape of a palm are arranged in a mirror-symmetrical manner to each other on one side of the lower mold;
[0008] An upper mold moves in a direction approaching the lower mold, the upper mold is suspended above the lower mold, wherein the upper mold is made of a flexible material, and two receiving grooves 2 are arranged in a mirror-symmetrical manner and in the shape of a palm are provided on one side of the upper mold, and the receiving groove 1 corresponds to the receiving groove 2 in the upper and lower directions;
[0009] At least two sets of sampling jigs corresponding to the left and right hands respectively, and at least two sets of the sampling jigs are arranged between the lower die and the upper die. Among them, each set of the sampling jigs includes a sterile cotton cloth one for contacting the palm skin and a sterile cotton cloth two for contacting the back skin of the hand. The sterile cotton cloth one and the sterile cotton cloth two are both preset with a contamination layer and an inspection layer, and both the contamination layer and the inspection layer are marked with different colors for distinction. The contamination layer is detachably connected to the inspection layer.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1). By arranging two sets of sampling jigs corresponding to the left and right hands respectively between the upper die and the lower die in this device, and each set of sampling jigs includes a sterile cotton cloth one and a sterile cotton cloth two for contacting the palm and the back of the hand, and each jig is provided with a contamination layer and an inspection layer. During sampling, according to the setting that the inspection layer contacts the skin, first place the palms down into the receiving grooves pre-lined with sterile cotton cloth one respectively, and at the same time cover the back of the hands with sterile cotton cloth two. As the upper die and the lower die move relative to each other, the inspection layer can be in close contact with the palms and the backs of both hands at one time for sampling processing, greatly shortening the sampling time, improving the sampling efficiency. At the same time, the entire areas of the palms and the backs of the hands are covered by the sampling jigs, ensuring the comprehensiveness of sampling, reducing the errors caused by incomplete sampling. At the same time, since the sampling process is completed by a mechanical device, the interference of human factors is reduced, and the accuracy of sampling is improved.
[0012] 2). In summary, compared with the traditional cumbersome sampling method, this detection not only improves the efficiency and accuracy of hand hygiene monitoring, but also makes the sampling process simpler and faster, reducing the work burden of medical staff and improving the user experience.
[0013] On the basis of the above technical solutions, the present utility model can be further improved as follows.
[0014] Further, it further includes a driving member for driving the upper die to move. The driving member includes a support plate in an inverted "U" shape, a guide post, a slider, a pressing plate, and a cylinder. The support plate is fixed on the machine table. One end of the guide post is fixed on the machine table and the other end extends and is fixed on the support plate. The slider slides on the guide post. The pressing plate is sleeved outside the slider. The cylinder is fixed on the support plate, and the driving end of the cylinder is connected to the pressing plate.
[0015] Further, the driving member further includes a buffer assembly. The buffer assembly is arranged on the pressing plate. The buffer assembly includes a bearing plate, a buffer plate, a spacer rod, a plurality of sliding rods, and buffer springs sleeved outside each sliding rod. The spacer rod is fixed at the bottom of the pressing plate. The bearing plate is fixed at the bottom of the spacer rod. One end of each sliding rod penetrates through the bearing plate, and the buffer plate is fixed at the other end of the sliding rod.
[0016] Furthermore, the upper mold is fixed on the bottom of the buffer plate.
[0017] The beneficial effect of adopting the above further scheme is that the pressing plate is driven by the driving end of the cylinder, and the pressing plate drives the slider to slide along the axial direction of the guide column. Therefore, the pressing plate can drive the bearing plate and the buffer plate to move along the axial direction of the guide column and close to the lower mold. Since the upper mold is fixed on the buffer plate, the upper mold automatically moves close to the lower mold, so that the sterile cotton cloth covering the back of the hand is tightly attached to the back of the hand, reducing the air gap between the inspection layer and the skin;
[0018] Secondly, a plurality of sliding rods with buffer springs are provided between the buffer plate and the supporting plate, and one end of the sliding rods passes through the supporting plate. Therefore, when the lower mold has touched the back of the hand, the cylinder continues to drive. As the supporting plate continues to move downward and begins to slightly compress the reset spring, the cylinder stops driving at this moment. By setting the maximum stroke of the cylinder drive, the reset spring can only be slightly compressed. While utilizing the preload force of the reset spring, the sterile cotton cloth is in close contact with the skin, and sufficient buffer distance is reserved between the supporting plate and the buffer plate, so that the buffer plate and the lower mold can continue to move. Even if the cylinder fails, only the upper mold needs to be lifted upward to allow the sampler's hands to be pulled out of the upper and lower molds, thereby ensuring the safety of the sampling process.
[0019] Furthermore, the lower mold and the upper mold are both made of medical grade silicone.
[0020] The beneficial effect of adopting the above further scheme is that the medical-grade silicone is soft and has good elasticity, and can adapt well to the contour of the hand, ensuring a close fit between the hand and the jig during the sampling process. The soft and comfortable touch not only reduces the discomfort of the sampler, but also improves their acceptance and cooperation.
[0021] Furthermore, the color of the inspection layer mark is white, and the word "inspection" is engraved on the side of the inspection layer that contacts human skin.
[0022] Furthermore, the color of the pollution layer is red.
[0023] The beneficial effect of adopting the above further scheme is that through the sharp color contrast (white and red), the operator can quickly distinguish the test layer from the contaminated layer. After the sampling is completed, it is convenient for the operator to peel off the contaminated layer from the test layer, reducing the possibility of confusion and misoperation. The intuitive visual identification makes the sampling process clearer and more orderly, and improves the accuracy and efficiency of the operation. The contaminated surface is marked in red, which has a strong warning color and can remind the operator of the importance of aseptic operation.
[0024] In addition, after the contaminated layer is peeled off from the inspection layer, the word "inspection" is engraved on the side of the inspection layer that contacts the human skin, so as to remind the inspector to quickly inspect the side that contacts the skin.

The total bacterial colony counts monitored for sanitary hand disinfection should be ≤10cfu / cm2, while the total bacterial colony counts monitored for surgical hand disinfection should be ≤5cfu / cm2.
[0033] Due to the complexity of the hand skin area, according to the current hand disinfection monitoring sampling method, a single cotton swab is used to rub both hands area by area. Not only does it take a long time to rub and have a slow sampling efficiency, but it may also cause omissions in the rubbing due to human factors, resulting in incomplete sampling, errors between the test results and the actual situation, and an increased risk of cross-infection in hospitals. In response to this, the utility model proposes a clinical hand disinfection test structure to solve the above problems.
[0034] The utility model provides the following preferred embodiments
[0035] like Figure 1-Figure 4 As shown, a clinical hand disinfection inspection structure comprises:
[0036] Machine 100;
[0037] The lower mold 200 is disposed on the top of the machine platform 100, wherein the lower mold 200 is made of a flexible material, and two receiving grooves 201 in the shape of a palm and arranged in mirror symmetry with each other are opened on one side of the lower mold 200;
[0038] The upper mold 300 moves in a direction close to the lower mold 200, and the upper mold 300 is suspended above the lower mold 200, wherein the upper mold 300 is made of a flexible material, and two receiving grooves 301 in the shape of a palm are arranged in a mirror-symmetrical manner to each other on one side of the upper mold 300, and the receiving groove 201 corresponds to the receiving groove 201 in the upper and lower directions;
[0039] At least two groups of sampling jigs 400 corresponding to the left hand and the right hand respectively, at least two groups of sampling jigs 400 are arranged between the lower mold 200 and the upper mold 300, wherein each group of sampling jigs 400 includes a sterile cotton cloth 1 400a for contacting the palm skin and a sterile cotton cloth 2 400b for contacting the back skin of the hand, the sterile cotton cloth 1 400a and the sterile cotton cloth 2 400b are both preset with a contaminated layer 400c and a test layer 400d, and the contaminated layer 400c and the test layer 400d are both marked with different colors for distinction, and the contaminated layer 400c is detachably connected to the test layer 400d;
[0040] By arranging two groups of sampling jigs 400 corresponding to the left hand and the right hand respectively between the upper mold 300 and the lower mold 200, and each group of sampling jigs 400 includes a sterile cotton cloth 1 400a and a sterile cotton cloth 2 400b for contacting the palm and the back of the hand, and each jig is provided with a contamination layer 400c and a test layer 400d. When sampling, according to the setting that the test layer 400d is in contact with the skin, the palms are first placed downward in the receiving grooves padded with the sterile cotton cloth 1 400a in advance, and the sterile cotton cloth 2 400b is covered on the On the back of the hand, with the relative movement of the upper mold 300 and the lower mold 200, the inspection layer 400d can be brought into close contact with the palms and backs of both hands at one time for sampling, which greatly shortens the sampling time and improves the sampling efficiency. At the same time, the sampling fixture 400 covers the entire area of the palm and back of the hand, ensuring the comprehensiveness of the sampling and reducing the errors caused by incomplete sampling. At the same time, since the sampling process is completed by a mechanical device, the interference of human factors is reduced, and the accuracy of sampling is improved;
[0041] In summary, compared with the traditional cumbersome sampling method, this detection not only improves the efficiency and accuracy of hand hygiene monitoring, but also makes the sampling process simpler and faster, reducing the workload of medical staff and enhancing the user experience.
[0042] In this embodiment, as Figure 1-Figure 4 shown, it further includes a driving member 500 for driving the upper mold 300 to move. The driving member 500 includes a support plate 510 in an inverted "U" shape, a guide post 520, a slider 530, a pressing plate 540, and a cylinder 550. The support plate 510 is fixed on the machine table 100. One end of the guide post 520 is fixed on the machine table 100 and the other end extends and is fixed on the support plate 510. The slider 530 slides on the guide post 520. The pressing plate 540 is sleeved outside the slider 530. The cylinder 550 is fixed on the support plate 510, and the driving end of the cylinder 550 is connected to the pressing plate 540;
[0043] The driving member 500 further includes a buffer assembly 560. The buffer assembly 560 is arranged on the pressing plate 540. The buffer assembly 560 includes a bearing plate 561, a buffer plate 562, a spacer rod 563, a plurality of sliding rods 564, and a buffer spring 565 sleeved outside each sliding rod 564. The spacer rod 563 is fixed at the bottom of the pressing plate 540. The bearing plate 561 is fixed at the bottom of the spacer rod 563. One end of each sliding rod 564 penetrates through the bearing plate 561, and the buffer plate 562 is fixed at the other end of the sliding rod 564. The upper mold 300 is fixed at the bottom of the buffer plate 562;
[0044] The driving end of the cylinder 550 drives the pressing plate 540. The pressing plate 540 drives the slider 530 to slide along the axial direction of the guide post 520. Therefore, the pressing plate 540 can drive the bearing plate 561 and the buffer plate 562 to also move along the axial direction of the guide post 520 and approach the lower mold 200. Since the upper mold 300 is fixed on the buffer plate 562, the movement of the upper mold 300 automatically approaching the lower mold 200 is realized, thereby tightly fitting the sterile cotton cloth II 400b covering the back of the hand to the back of the hand, reducing the air gap between the test layer 400d and the skin;
[0045] Secondly, a plurality of slide bars 564 with buffer springs 565 are provided between the buffer plate 562 and the carrier plate 561, and one end of the slide bar 564 penetrates the carrier plate 561 (in order to prevent the slide bar 564 from falling off the carrier plate 561, the diameter of one end of the slide bar 564 should be larger than the diameter of the through hole on the carrier plate 561). Therefore, when the lower mold 200 has touched the back of the hand, the cylinder 550 continues to drive, and as the carrier plate 561 continues to move downward and starts to slightly compress the return spring, the cylinder 550 Stop driving, and set the maximum stroke of the cylinder 550 to only slightly compress the return spring. Under the action of the return spring preload, the sterile cotton cloth is in close contact with the skin, while ensuring that there is enough buffer distance between the supporting plate 561 and the buffer plate 562, so that the buffer plate 562 and the lower mold 200 can continue to move. Even if the cylinder 550 fails, it is only necessary to lift the upper mold 300 upwards to allow the sampler's hands to be pulled out of the upper and lower molds 200, thereby ensuring the safety of the sampling process.
[0046] In this embodiment, Figure 1-Figure 4 As shown, the lower mold 200 and the upper mold 300 are both made of medical-grade silicone. Medical-grade silicone is soft and has good elasticity. It can adapt well to the contour of the hand and ensure a close fit between the hand and the jig during the sampling process. The soft and comfortable touch not only reduces the discomfort of the samplers, but also improves their acceptance and cooperation.
[0047] In this embodiment, Figure 1-Figure 4 As shown, the color of the inspection layer 400d is white, and the word "inspection" is engraved on the side of the inspection layer 400d that contacts the human skin, and the color of the contamination layer 400c is red;
[0048] Through the sharp color contrast (white and red), the operator can quickly distinguish the test layer 400d from the contaminated layer 400c. After the sampling is completed, it is convenient for the operator to peel off the contaminated layer 400c from the test layer 400d, reducing the possibility of confusion and misoperation. The intuitive visual identification makes the sampling process clearer and more orderly, and improves the accuracy and efficiency of the operation. The contaminated surface is marked in red, which has a strong warning color and can remind the operator of the importance of aseptic operation.
[0049] In addition, after the contamination layer 400c is peeled off from the inspection layer 400d, the word "inspection" is engraved on the side of the inspection layer 400d that contacts the human skin, so as to remind the inspector to quickly inspect the side that contacts the skin.
[0050] The specific working process of the utility model is as follows:
[0051] (1) Place sterile cotton cloth 400a in the holding tank 201.
[0052] First, according to the sampling method of the "Standards for Hand Hygiene of Medical Personnel": the laid sterile cotton cloth 400a should be soaked in the sterile eluent of the neutralizer, and after the sampling is completed, it should be put into the sterile eluent test tube containing the corresponding neutralizer. At this time, according to the way that the contaminated layer 400c of the sterile cotton cloth 400a contacts the lower mold 200, the soaked sterile cotton cloth 400a is respectively placed in the receiving groove 201, and then both hands are placed on the sterile cotton cloth 400a in the receiving groove 201 with the palms facing down.
[0053] (2) Place 400b sterile cotton cloth on the back of both hands.
[0054] Similarly, in the same manner that the contaminated layer 400c of the second sterile cotton cloth 400b contacts the upper mold 300, the inspection layer 400d of the second sterile cotton cloth 400b is covered on the backs of both hands.
[0055] (3) Sampling
[0056] The pressing plate 540 is driven by the driving end of the cylinder 550, and the pressing plate 540 drives the slider 530 to slide along the axial direction of the guide column 520. Therefore, the pressing plate 540 can drive the supporting plate 561 and the buffer plate 562 to move along the axial direction of the guide column 520 and close to the lower mold 200. Since the upper mold 300 is fixed on the buffer plate 562, the upper mold 300 automatically moves close to the lower mold 200 until it contacts the sterile cotton cloth 400b, thereby making the sterile cotton cloth 400b covering the back of the hand fit tightly against the back of the hand.
[0057] (4) Peeling off the contaminated layer 400c from the inspection layer 400d
[0058] After the sampling is completed, the operator quickly distinguishes the test layer 400d and the contaminated layer 400c based on the distinct color contrast (white and red), peels the contaminated layer 400c off the test layer 400d, and then puts the test layer 400d into a sterile eluent test tube containing a corresponding neutralizer.
[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
