[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0047] The purpose of this invention is to provide a contamination-proof sterile solution bottle cap to solve the problems existing in the prior art. When using a saline infusion bottle, the cap can be opened to complete the liquid dispensing or infusion, and there will be no situation where the fingers directly touch the mouth of the saline infusion bottle, thus fundamentally eliminating the problem of contamination at the mouth of the saline bottle.
[0048] This utility model also provides a sterile solution bottle for easy dispensing, including a bottle body, a bottle neck, and the aforementioned anti-contamination sterile solution bottle cap. A one-way ventilation component connecting the inside and outside is provided on the bottle neck, allowing outside air to enter the sterile solution bottle for easy dispensing in one direction, balancing the internal air pressure of the sterile solution bottle for easy dispensing, and speeding up the dispensing speed without the need for an external air valve.
[0049] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0050] like Figure 1-4 As shown, this utility model provides a contamination-resistant sterile solution bottle cap, including a flip cap 1 and a fixing part 3. When the contamination-resistant sterile solution bottle cap is closed, the flip cap 1 is fastened to the fixing part 3. The connection between the flip cap 1 and the fixing part 3 is sealed by a sealing strip 2. A connecting part 4 is provided on the upper outer edge of the fixing part 3, and the lower outer edge of the flip cap 1 is connected to the connecting part 4. When the contamination-resistant sterile solution bottle cap is opened, the flip cap 1 flips upward around the connection position between the flip cap 1 and the connecting part 4. A flange is provided on the upper outer edge of the flip cap 1. The flange is away from the connecting part 4. A first connecting seal is provided inside the flip cover 1. A second connecting seal is provided on the top of the fixing part 3. When the anti-contamination sterile solution bottle cap is closed, the first connecting seal and the second connecting seal combine with each other to form a seal. The first connecting seal is a first connecting ring 11. The first end of the first connecting ring 11 is fixed to the inside of the flip cover 1. The second end of the first connecting ring 11 extends out of the lower edge of the flip cover 1. A first connecting groove 12 is formed between the first connecting ring 11 and the side of the flip cover 1.
[0051] like Figure 3-6As shown, the second sealing component includes a second sealing ring 31 and a third sealing ring 33, which are concentrically arranged. The second sealing ring 31 is located outside the third sealing ring 33, and a second sealing groove 32 is formed between the second sealing ring 31 and the third sealing ring 33. When the anti-contamination sterile solution bottle cap is closed, the second sealing ring 31 extends into the first sealing groove 12, and the first sealing ring 11 extends into the second sealing groove 32. A sealing plug 34 is installed on the top part of the fixing part 3 located inside the third sealing ring 33. A recessed part 35 is provided on the sealing plug 34. The fixed part 3 is provided with a fixed thread 36 located below the sealing rubber stopper 34. The recessed part 35 is composed of valves 37 on the side opposite to the flip cover 1. The valves 37 can separate under external force. When the liquid collection needle is inserted, the valves 37 separate. When no liquid is collected, the valves 37 close to form a seal. The number of valves 37 is not fixed. The material of the valves 37 is common soft materials such as silicone. A moisture-absorbing sheet is pasted on the inside of the flip cover 1 to absorb moisture in the closed state. When the flip cover 1 is fastened, the moisture-absorbing sheet can reduce the humidity in the sealed space, creating a dry space that is not suitable for the growth of bacteria, making the infusion bottle more hygienic.
[0052] like Figure 3 As shown, the flip cover 1 is a concave cover.
[0053] This invention also provides a sterile solution bottle for convenient dispensing, such as... Figure 7 As shown, the bottle includes a bottleneck 5, a body 7, and the aforementioned anti-contamination sterile solution bottle cap. The anti-contamination sterile solution bottle cap, the bottleneck 5, and the body 7 are sequentially connected to form the sterile solution bottle that facilitates liquid dispensing. A one-way ventilation component 6 is provided on the bottleneck 5, and the one-way ventilation component 6 communicates with the interior of the bottleneck 5.
[0054] like Figure 7 and 9As shown, the one-way ventilation assembly includes a stopper 61, a connecting strap 62, a one-way membrane installation tube 63, and a one-way membrane 64. The edge of the stopper 61 is connected to the first end of the connecting strap 62, and the second end of the connecting strap 62 is fixed to the outside of the one-way membrane installation tube 63. The stopper 61 can seal the first end of the one-way membrane installation tube 63, and the second end of the one-way membrane installation tube 63 is connected to the bottleneck 5. The one-way membrane 64 is installed on the one-way membrane installation tube 63. When the first end of the one-way membrane installation tube 63 is open, outside air enters the easy-to-dispense sterile solution bottle through the one-way membrane 64. During the process of liquid collection or infusion, the air entering the easy-to-dispense sterile solution bottle from the one-way membrane 64 can fill the space inside the bottle originally occupied by the lost solution, balance the gas pressure inside and outside the easy-to-dispense sterile solution bottle, and ensure smooth liquid dispensing of the easy-to-dispense sterile solution bottle without the need for an external ventilation device.
[0055] like Figure 8 As shown, the bottom of the bottle body 7 has a recessed portion, and a pull ring 71 is provided in the recessed portion. During infusion, the pull ring 71 can be hung on the hook of the infusion stand.
[0056] like Figure 7 and 8 As shown, the bottleneck 5 and the bottle body 7 are an integral structure. The upper part of the bottle body 7 is a platform structure with a circular top surface and an elliptical bottom surface. The lower part of the bottle body 7 is a column structure with elliptical top and bottom surfaces. The platform structure at the top of the bottle body 7 matches the hand shape when a person holds an item, making it convenient for medical staff to frequently pick up the item. The side shape of the column structure at the bottom of the bottle body 7 matches the hand shape when a person holds an item, allowing medical staff to grip the sterile solution bottle more firmly when using it.
[0057] In a preferred embodiment, the upper bottom surface of the bottle body 7 has the same shape as the lower top surface of the bottle body 7, so as to avoid the presence of protruding edges on the bottle body 7 that would hinder medical staff from holding and taking it. The bottle body 7 is made of transparent material, and scale lines are provided on the side wall of the bottle body 7.
[0058] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
