[0019] 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.
[0020] In this embodiment of the utility model, please refer to Figures 1 to 5A saline solution bottle for cleaning includes a bottle body 1 containing saline cleaning solution. The top of the bottle body 1 has a fixed bottle opening 2 communicating with its interior. The top of the fixed bottle opening 2 has a liquid outlet 3 communicating with its interior. The fixed bottle opening 2 is threadedly connected to a threaded cap 4. The inner wall of the top center of the threaded cap 4 has a sealing ring cap 5, which abuts against the liquid outlet 3. The center of the sealing ring cap 5 has an opening spike 6, which is connected to the threaded cap 4. A positioning ring 7 is fitted on the fixed bottle opening 2, with its bottom end abutting against the fixed bottle opening 2 and its top end abutting against the bottom of the threaded cap 4.
[0021] In the initial state, the outlet bottle 3 is sealed, the bottom of the positioning ring 7 abuts against the fixed bottle 2, the top of the positioning ring 7 abuts against the bottom of the threaded cap 4, and the opening spike 6 is located at the top of the outlet bottle 3.
[0022] When it is necessary to open the bottle, rotate the threaded cap 4 to disengage it from the fixed bottle mouth 2, remove the positioning ring 7, and then reconnect the threaded cap 4 to the fixed bottle mouth 2. Continue to rotate the cap so that it moves towards the side closer to the bottle body 1, causing the opening spike 6 to move. When the threaded cap 4 is screwed to a certain extent, the opening spike 6 will pierce the top of the outlet bottle mouth 3. Then rotate the threaded cap 4 in the opposite direction to remove it, so that the saline cleaning solution inside the bottle body 1 can be poured out for use.
[0023] When sealing is required after use, connect the threaded cap 4 to the fixed bottle mouth 2. When the threaded cap 4 is rotated to abut against the fixed bottle mouth 2, the opening spike 6 pierces into the liquid outlet 3 to seal the liquid outlet 3. At the same time, the sealing ring cap 5 is located outside the liquid outlet 3 and abuts against it, thus achieving a secondary seal and a better sealing effect.
[0024] As one embodiment of this utility model, please refer to Figure 2 and Figure 3 The outer wall of the fixed bottle opening 2 is provided with threaded protrusions, which are divided into upper and lower layers. Each layer of threaded protrusions has a notch. The inner wall of the threaded cap 4 is provided with threaded grooves that match the threaded protrusions. Regardless of whether the fixed bottle opening 2 has a retaining position, the threaded cap 4 can be tightened by tightening the two layers of threaded protrusions. The notch is used to allow the threaded groove to switch freely between the upper and lower layers of threaded protrusions and to tighten it, thereby improving the sealing effect of the secondary seal.
[0025] This threaded connection method ensures that the threaded cap 4 is tightly connected to the fixed bottle mouth 2, improving the sealing performance, and also facilitates the tightening and loosening of the threaded cap 4.
[0026] As one embodiment of this utility model, please refer to Figures 1 to 3 The threaded cap 4 has anti-slip texture on its outer wall.
[0027] The anti-slip texture design increases the friction between the hand and the screw cap 4, making it easier and more stable for the user to screw on the screw cap 4, especially when the hand is wet or the bottle body 1 is at a certain angle, it can effectively prevent the screw cap 4 from slipping.
[0028] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 A protective cover 8 is fitted onto the threaded cover 4.
[0029] The protective cover 8 can protect the threaded cover 4, preventing it from being damaged by external collisions, scratches, etc. during storage, transportation or use, thereby extending the service life of the threaded cover 4.
[0030] The working principle of this utility model is as follows: In the initial state, the outlet bottle 3 is sealed, the bottom end of the positioning ring 7 abuts against the fixed bottle 2, the top end abuts against the bottom of the threaded cap 4, and the opening spike 6 is located at the top of the outlet bottle 3.
[0031] When it is necessary to open the bottle, rotate the threaded cap 4 to disengage it from the fixed bottle mouth 2, remove the positioning ring 7, and then reconnect the threaded cap 4 to the fixed bottle mouth 2. Continue to rotate the cap so that it moves towards the side closer to the bottle body 1, causing the opening spike 6 to move. When the threaded cap 4 is screwed to a certain extent, the opening spike 6 will pierce the top of the outlet bottle mouth 3. Then rotate the threaded cap 4 in the opposite direction to remove it, so that the saline cleaning solution inside the bottle body 1 can be poured out for use.
[0032] When sealing is required after use, connect the threaded cap 4 to the fixed bottle mouth 2. When the threaded cap 4 is rotated to abut against the fixed bottle mouth 2, the opening spike 6 pierces into the liquid outlet 3 to seal the liquid outlet 3. At the same time, the sealing ring cap 5 is located outside the liquid outlet 3 and abuts against it, thus achieving a secondary seal and a better sealing effect.
[0033] The built-in spike automatic opening and secondary sealing structure in this utility model patent has significant practical application value in medical scenarios. Its design precisely meets the high requirements of the medical environment for safety, convenience, and professionalism, specifically reflected in the following aspects:
[0034] I. Improve the efficiency of medical and nursing operations and reduce preparation time.
[0035] One-handed operation, quick response to needs
[0036] In medical settings (such as emergency wound cleaning and surgical care), healthcare workers often need to quickly dispense saline solution. The built-in spike structure allows for one-handed opening via a simple "rotate the threaded cap → spike automatically pierces the bottle opening" operation, eliminating the need for tweezers, scissors, or other tools. For example, in trauma emergency care, healthcare workers can hold the bottle with one hand and unscrew the cap with the other, simultaneously opening and dispensing the solution, shortening preparation time before wound irrigation. Compared to traditional saline bottles that require tools to open, this increases operational efficiency by approximately 50%, making it particularly suitable for emergency treatment scenarios.
[0037] Standardized opening procedures reduce operational errors
[0038] Traditional saline bottles require forceful tearing or piercing to open, which can easily lead to bottle breakage or liquid splashing due to improper force control. This new design uses a positioning ring and threaded screw to control the depth of the screw, ensuring that the spike reliably pierces the bottle opening without damaging the bottle body, thus avoiding delays in nursing procedures due to operational errors. For example, even novice nurses can complete the opening process using a fixed procedure of "removing the positioning ring → secondary screwing," reducing training costs and operational risks.
[0039] II. Enhance safety in medical settings and reduce the risk of infection.
[0040] Avoid physical damage during the opening process
[0041] Traditional saline bottles may suffer from glass / plastic fragments falling from the bottle neck due to rough handling, or contamination may occur due to tools (such as scissors) coming into contact with the bottle neck. The built-in spike structure, through its internal piercing design, eliminates the risk of contamination at the source by directly driving the spike to pierce the bottle neck with the screw cap rotated, without the need for external tools.
[0042] Medical staff suffered hand injuries from the broken bottle opening;
[0043] Foreign objects (such as tool scraps or glove fibers) fall into the bottle and contaminate the saline solution.
[0044] Reliable sealing ensures the sterility of the liquid.
[0045] Medical saline solution must strictly adhere to aseptic standards. This design, through a double-sealed connection between the sealing ring cap and the dispensing bottle opening, combined with the tightness of the threaded connection, effectively prevents bacterial intrusion during transportation or storage. For example, when hospital pharmacies store saline bottles in bulk, this design avoids liquid leakage or contamination caused by loose caps, making it particularly suitable for long-term storage in high-temperature and high-humidity environments.
[0046] III. Adapt to diverse medical scenarios and enhance the nursing experience
[0047] Suitable for mobile healthcare and home care
[0048] In mobile scenarios such as ambulances and field medical services, saline bottles may leak due to loose caps caused by bumps and vibrations. This design, with its threaded and spiked seal, can withstand a certain amount of impact, ensuring safe transport of the liquid.
[0049] In home care scenarios (such as umbilical cord care for infants and wound cleaning for the elderly), non-professional users can open the package with a simple rotation, avoiding usage obstacles caused by complicated operations. It is especially suitable for people with weak hand strength (such as the elderly).
[0050] Compatible with different nursing operation needs
[0051] Precise control of liquid output: After opening, the liquid output speed can be controlled by the amount of screwing on the screw cap (for example, when slowly rinsing a wound, the screw cap can be kept slightly open to create a small flow rate).
[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
