Abstract
Description
Technical Field
[0001] A sterilization packaging bag for dental handpieces belongs to the field of dental instrument packaging technology. Background Technology
[0002] Dental handpiece: Also known as a high-speed dental turbine handpiece or dental treatment handpiece, it is an indispensable tool in dental treatment. It mainly consists of a high-speed turbine head, a handle, air and water tubing, etc. It uses high-pressure air to drive the turbine head to generate high-speed rotation, which drives the cutting tools to perform operations such as drilling, grinding, and cutting teeth.
[0003] Paper-plastic bags: Packaging materials for medical supplies made of dialysis paper and composite film heat-sealed together, which can indicate whether the sterilization process has been carried out and require final sterilization (i.e., sterilization after packaging).
[0004] Dental handpieces are mostly used for dental treatments. After cleaning, dental handpieces need to be injected with lubricant before packaging and sterilization. After sterilization, the injected lubricant often contaminates the paper-plastic bag. To solve this problem, existing technologies, such as patent CN217416639U, use absorbent paper inside the paper-plastic bag to absorb the overflowing lubricant. However, the absorbent paper is too large, occupying a large area of the dialysis paper, which greatly affects the dialysis function of the dialysis paper. Moreover, the absorbent paper alone cannot completely absorb the lubricant overflowing from the dental handpiece, and does not provide complete protection. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sterilization packaging bag for dental handpieces. The indicator card inside the sterilization packaging bag is arranged in layers. Under the oil-absorbing layer, there is also a water-absorbing layer, a hydrophobic layer and a film layer. The excess lubricating oil can be locked in the oil-absorbing layer by utilizing the immiscibility of water and oil, and the film layer can effectively prevent the lubricating oil from contaminating the dialysis paper.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The sterilization packaging bag for dental handpieces includes a body and a chemical indicator card. The body includes a body film layer and dialysis paper. A cavity for placing the dental handpiece is formed between the body film layer and the dialysis paper. The chemical indicator card is disposed in the cavity. The chemical indicator card includes an indicator card film layer, a hydrophobic layer, a water-absorbing layer, an oil-absorbing layer, and a chemical indicator layer. The indicator card film layer is disposed close to the dialysis paper, and the chemical indicator layer is disposed away from the dialysis paper. The hydrophobic layer, the water-absorbing layer, and the oil-absorbing layer are disposed sequentially between the indicator card film layer and the chemical indicator layer.
[0007] Preferably, the area of the indicator card film layer is larger than the area of the oil-absorbing layer, and the area of the oil-absorbing layer is larger than the area of the chemical indicator layer.
[0008] Preferably, there are two chemical indicator cards, corresponding to the two ends of the dental handpiece.
[0009] Preferably, an adhesive layer is provided between the indicator card film layer and the hydrophobic layer.
[0010] Preferably, an adhesive layer is provided between the hydrophobic layer and the absorbent layer.
[0011] Preferably, an adhesive layer is provided between the oil-absorbing layer and the water-absorbing layer.
[0012] Preferably, an adhesive layer is provided between the indicator card film layer and the dialysis paper, and the chemical indicator layer and the main film layer are spaced apart.
[0013] Preferably, the body film layer and the edge of the dialysis paper are provided with multiple heat-sealed edges.
[0014] Preferably, the main film layer and the end of the dialysis paper are provided with an opening communicating with the cavity, and an easy-tear opening is provided on the main body on the opposite side of the opening.
[0015] Compared with existing technologies, the beneficial effects of this technical solution are: The chemical indicator card of this invention has multiple layers. On the lower side of the oil-absorbing layer, a water-absorbing layer, a hydrophobic layer, and an indicator card film layer are arranged in sequence. For the oil outlet of the dental handpiece, multiple layers of protection are set up. The property that water and oil are immiscible can lock excess lubricating oil in the oil-absorbing layer. Furthermore, even if the lubricating oil passes through the oil-absorbing layer, an indicator card film layer that can block the lubricating oil is set on the side close to the dialysis paper, which can further prevent the lubricating oil from contaminating the dialysis paper.

Two chemical indicator cards 2 are pasted on the inner surface of the dialysis paper at intervals.
