Description

Technical Field

[0001] The invention discloses a BD test kit, belonging to the technical field of medical devices. Background Art

[0002] In the field of hospital sterilization supply, daily performance monitoring of pressure steam sterilizers is an important prerequisite for ensuring reliable sterilization effects. At present, the most commonly used monitoring method is BD test. When conducting BD test, the cold air removal and saturated steam penetration effects of pressure steam sterilizers are monitored by the color change of chemical indicator ink on the standard test chart. If the color change of the test chart is uniform and complete, it indicates that the sterilizer has good evacuation effect and steam penetration effect.

[0003] However, when the sterilizer fails, the standard test chart cannot accurately indicate the status of the sterilizer. If other departments in the hospital urgently need to use qualified instruments or dressings to be sterilized, the supply room cannot guarantee that these items will be issued on time. This delays the normal sterilization work of the hospital supply room with limited equipment and reduces the efficiency of infection control.

[0004] The Chinese utility model patent entitled "A BD test package" (application number 201621377964.9) submitted by the applicant of the present application on December 15, 2016 discloses a technical solution, in which a BD test package is provided. The early warning test pattern in the test package can have a higher sensitivity to the evacuation and steam penetration effects of the sterilizer, and has the function of predicting in advance the possibility of an impending failure of the sterilizer.

[0005] However, when the technical solution was implemented, it was found that the following deficiencies still existed: the test package was large in size, which caused waste to a certain extent, especially after the test, the package needed to be opened for interpretation, which was rather cumbersome. Utility Model Content

[0006] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and to provide a BD test package which, by setting an observation window, respectively displays the indicator inks on the surfaces of a standard test chart and a warning test chart, through which the test results can be directly observed without unpacking, thereby reducing the complexity of the operation.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the BD test package includes a standard test chart and a warning test chart, and indicator inks with different cold air sensitivities are respectively coated on the surfaces of the standard test chart and the warning test chart, and is characterized in that: a surface layer and a bottom layer that are bonded to each other are provided, the standard test chart and the warning test chart are both placed between the surface layer and the bottom layer, and observation windows for displaying the surface inks of the standard test chart and the warning test chart are respectively opened on the surface layer and the bottom layer.

[0008] Preferably, a cavity is formed between the surface layer and the bottom layer, and the standard test pattern and the warning test pattern are located in the cavity.

[0009] Preferably, an annular breathable cardboard layer is arranged on the outer ring between the surface layer and the bottom layer.

[0010] Preferably, the surface layer and the breathable cardboard layer are adhered and fixed by a glue layer.

[0011] Preferably, the bottom layer and the breathable cardboard layer are adhered and fixed by a lower glue layer.

[0012] Preferably, the size of the surface layer and the bottom layer are both 90mm*60mm.

[0013] Preferably, the size of the observation window is 55mm*25mm.

[0014] Preferably, both the surface layer and the bottom layer are made of transparent PET film.

[0015] Preferably, the cold air sensitivity of the indicator ink on the early warning test chart is greater than the cold air sensitivity of the indicator ink on the surface of the standard test chart.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] An observation window is set on the surface of this BD test package to display the indicator ink on the surface of the standard test chart and the warning test chart respectively. The test results can be directly observed through the observation window without unpacking, which reduces the complexity of operation.

[0018] During the test, the surface and bottom layers are made of airtight PET film, which greatly reduces the steam penetration path and allows it to penetrate only from the side, greatly delaying the time that the internal standard test chart and warning test chart are in contact with saturated steam, ensuring the accuracy of this BD test package.

[0019] Compared with the existing technology, the volume of the BD test package is reduced by 92.5% and the weight is reduced by about 95%, which greatly reduces the cost of materials and is convenient for transportation and storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figures 1 to 3 It is the best embodiment of the utility model, and the following Figures 1 to 3 The utility model is further described.

[0025] like Figure 1~2 As shown, a BD test package is a rectangular card structure, including a surface layer 1 and a bottom layer 4 that are attached to each other. The surface layer 1 and the bottom layer 4 are both made of a transparent PET film that is commonly used in the art and can withstand high temperatures. An observation window 2 is provided on the surface of the surface layer 1 and the bottom layer 4. The standard test Figure 3 The ink on the surface is displayed at the observation window 2 of the surface layer 1, and the ink on the surface of the warning test chart 5 is displayed at the observation window 2 of the bottom layer 4. The cold air sensitivity of the ink indicated on the warning test chart 5 is greater than that of the standard test Figure 3 The surface indicates the cold air sensitivity of the ink.

[0026] The size of the surface layer 1 and the bottom layer 4 are both 90mm*60mm, and the thickness of this BD test chart is 3mm. The size of the observation window 2 is 55mm*25mm. In the prior art, the size of the BD test package is usually 120mm×120mm*15mm. Therefore, compared with the prior art, the volume of this BD test package is reduced by 92.5%, and the weight is reduced by about 95%, which greatly reduces the cost of materials and is convenient for transportation and storage.

[0027] Combination Figure 3 , a cavity 8 is formed between the surface layer 1 and the bottom layer 4, standard test Figure 3 and the warning test diagram 5 are placed in the cavity 8 respectively. An annular breathable cardboard layer 7 is arranged on the outer circumference between the surface layer 1 and the bottom layer 4, and the breathable cardboard layer 7 is glued and fixed to the surface layer 1 through the upper glue layer 6, and the breathable cardboard layer 7 is glued and fixed to the bottom layer 4 through the lower glue layer 9.

[0028] The specific working process and working principle are as follows:

[0029] The medical staff put the BD test package above the exhaust port of the pressure steam sterilizer, facing up, and run the BD test program. After the test, if the performance of the pressure steam sterilizer has declined, if the standard test Figure 3If the ink on the surface changes color completely, while the ink on the surface of the warning test figure 5 changes color incompletely, it means that the pressure steam sterilizer can continue to be used, but it needs to be repaired to eliminate possible hidden troubles, which serves as a warning. And the test results can be directly observed through the observation window 2 without unpacking, which reduces the complexity of the operation.

[0030] During the test, the surface layer 1 and the bottom layer 4 are made of airtight PET film, which greatly reduces the steam penetration path and allows it to penetrate only from the side, greatly delaying the internal standard test. Figure 3 And the early warning test Figure 5 contact time with saturated steam ensures the accuracy of this BD test package.

[0031] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
