Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical liquid dressing bottle. Background Art

[0002] Wound Care Solution (Medical Wound Care Film) is an active, absorbable biomaterial. After being sprayed on the wound surface, it solidifies into a liquid film within 3-5 minutes. It feels sticky to the touch, but becomes a transparent, smooth film visible in the light. It has excellent permeability and breathability, and can be as thick as 1-2 threads. It eliminates the need for cotton dressings, making it easier to observe the wound.

[0003] When the cover of some existing medical wound care liquid dressing bottles is removed or falls off, the dressing bottles may be squeezed, causing the wound care liquid inside to spray out, which has low practicality.

[0004] In view of this, research and improvement are conducted to the existing problems, and a medical liquid dressing bottle is provided, which can prevent the dressing bottle from being squeezed and causing the liquid to be sprayed out. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a medical liquid dressing bottle. The present invention locks the spray head when not in use by adding a protective shell to the outside of the spray bottle body, thereby protecting the spray bottle from misoperation. When in use, the upper shell is rotated to unlock the protective device, and then a period of pre-pressing is required to contact the spray bottle body, and continued pressing is required to spray. There is also a spring in this mechanism to automatically rebound when not in use. When not in use, the length of the spray bottle nozzle extending outside is only 8mm-10mm, and because of the self-locking mechanism, it is ensured that children will not be poked. The present invention has the characteristics of simple operation, simple structure, convenient installation, and convenient operation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] A medical liquid dressing bottle comprises a dust cover, an upper shell, a spray bottle, a spring, and a lower shell; the spray bottle comprises a bottle body, a nozzle, and a pressing boss; the spray bottle is placed in a housing formed by an upper shell and a lower shell; the upper shell comprises a through hole, a buckle, and a protrusion for allowing the nozzle to extend; the lower shell comprises a fixed stop and a positioning groove; the upper shell and the lower shell are capable of axial movement and radial rotation;

[0008] Rotate the upper shell. When the buckle of the upper shell contacts the fixed stop of the lower shell, it will lock automatically, limiting the downward movement of the upper shell. The length of the nozzle extending from the through hole is 8-10mm.

[0009] Rotate the upper shell and unlock it when the convex point of the upper shell contacts the groove of the lower shell. The upper shell will first pass through the pre-pressing state and then enter the press spray state.

[0010] In the pre-pressing state, the upper shell moves downward under pressure until it abuts against the pressing boss;

[0011] In the press spray state, the upper shell is continuously pressed, the upper shell abuts against and presses the pressing boss, and the nozzle sprays the spray;

[0012] The spring is used to restore the upper shell to its original height.

[0013] Preferably, a spring positioning rib is provided on the inner wall of the upper shell, the upper portion of the spring abuts against the spring positioning rib, and the lower portion of the spring abuts against the bottle body.

[0014] Preferably, the lower shell includes a running groove, and when the protrusion of the upper shell abuts against the positioning groove of the lower shell to be unlocked, the buckle slides up and down in the running groove as the upper shell and the lower shell move axially.

[0015] Preferably, the lower shell includes a guide groove. When the buckle of the upper shell abuts against the fixed stop of the lower shell and self-locks, the protrusion of the upper shell is located in the guide groove and a "click" sound is emitted to remind the user that the shell has been rotated into position.

[0016] Preferably, when the protrusion of the upper shell abuts against the positioning groove of the lower shell and is unlocked, a rotation into position reminder sound "click" is emitted.

[0017] Preferably, the outer wall of the upper shell is provided with a vertical groove, and the inner wall of the lower shell is provided with a vertical rib; the rib cooperates with the groove to guide the upper shell and avoid the lower shell.

[0018] Preferably, the dust cover is provided with a fixing protrusion, and the lower shell is provided with a fixing boss, and the fixing protrusion is correspondingly engaged with the fixing boss.

[0019] This utility model can realize 3 states:

[0020] State 1: Self-locking. Remove the dust cover and rotate the upper cover. The buckle in the upper shell contacts the fixed stop in the lower shell. The fixed stop acts as a limiter to prevent the upper shell from moving downward. In this state, the spray bottle nozzle only extends 8mm-10mm from the upper shell to avoid accidental injury to the patient. In this state, the self-locking function will not be accidentally triggered.

[0021] State 2: Pre-pressed state. Rotate the upper shell. When the raised dot on the upper shell aligns with the recessed groove in the lower shell, a click is heard, indicating unlocking. The latch in the upper cover engages the operating groove, allowing the upper shell to move downward until it contacts the pressing boss on the spray bottle, completing the pre-pressed state. The spring automatically rebounds the upper shell to its original height. This state allows the nozzle in the spray bottle to be fully extended and inserted into the nasal cavity before spraying the liquid dressing.

[0022] State 3: Press-to-spray state. After the pre-press state, the nozzle in the spray bottle is inserted into the nasal cavity. Continue to press the upper shell. At this time, the pressing boss of the spray bottle contacts the upper shell and is pressed, and the nozzle of the spray bottle sprays liquid dressing.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] When not in use, this spray bottle locks itself, preventing misuse. The nozzle of the spray bottle protrudes only 8-10 mm from the exterior of the upper shell, ensuring it won't poke children. When in use, the upper shell is rotated to unlock the protective device. A preliminary press is required to access the spray bottle, and further pressure is required to release the spray. This effectively prevents liquid dressings from being squeezed out when not in use, thus avoiding waste. The dust cover also prevents contamination of the nozzle when not in use, significantly improving the usability of the liquid dressing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described below with reference to specific embodiments.

[0036] See also Figure 1-10 : A medical liquid dressing bottle, comprising a dust cover 1, an upper shell 2, a spray bottle 3, a spring 4 and a lower shell 5. The spray bottle 3 comprises a bottle body 6, a nozzle 7 and a pressing boss 8. The spray bottle 3 is placed in a shell surrounded by the upper shell 2 and the lower shell 5. The upper shell 2 comprises a through hole 9 for allowing the nozzle 7 to extend, a buckle 10, a protrusion 11, a spring positioning rib 12 and a groove 13. The lower shell 5 comprises a fixed boss 14, a fixed stop 15, an in-position groove 16, a running groove 17, a guide groove 18 and a rib 19. The dust cover 1 is provided with a fixed protrusion 20. The dust cover 1 is correspondingly engaged with the fixed protrusion 14 of the lower shell 5 through the fixed protrusion 20.

[0037] The upper shell 2 and the lower shell 5 can move axially and rotate radially.

[0038] Rotate the upper shell 2, and when the buckle 10 of the upper shell 2 abuts the fixed stop 15 of the lower shell 5, the self-locking is achieved, limiting the downward movement of the upper shell 2, and the length of the nozzle 7 extending out of the through hole 9 is 8-10 mm. This state is usually regarded as the initial state or the unused state.

[0039] The upper shell 2 is rotated and unlocked when the protrusion 11 of the upper shell 2 abuts against the positioning groove 16 of the lower shell 5. Under pressure, the upper shell 2 first passes through a pre-pressing state and then enters a press spray state.

[0040] In the pre-pressed state, the upper shell 2 moves downward under pressure until it abuts against the pressing boss 8 .

[0041] In the press spray state, the upper shell 2 is continued to be pressed, the upper shell 2 abuts against and presses the pressing boss 8, and the nozzle 7 sprays the spray.

[0042] The spring 4 is used to restore the upper shell 2 to its original height. In one embodiment, the spring positioning rib 12 is provided on the inner wall of the upper shell 2, the upper portion of the spring 4 abuts against the spring positioning rib 12, and the lower portion of the spring 4 abuts against the bottle body 6.

[0043] When the buckle 10 of the upper shell 2 abuts against the fixed stop 15 of the lower shell 5 and is self-locked, the protrusion 11 of the upper shell 2 is located in the guide groove 18 and a "click" sound is emitted as a reminder of the rotation into position.

[0044] When the protrusion 11 of the upper shell 2 abuts the in-place groove 16 of the lower shell 5 to unlock, a rotation in-place reminder sound "click" is issued. At this time, along with the axial movement between the upper shell 2 and the lower shell 5, the buckle 10 slides up and down in the running groove 17.

[0045] The groove 13 is vertically arranged on the outer wall of the upper shell 2, and the rib 19 is vertically arranged on the inner wall of the lower shell 5. The rib 19 cooperates with the groove 13 to guide the upper shell 2 and avoid the lower shell 5.

[0046] This utility model can realize 3 states:

[0047] State 1: Self-locking state. Figure 8 As shown, remove the dust cover, rotate the upper cover, and the buckle in the upper shell abuts against the fixed stop in the lower shell. The fixed stop limits the upper shell to ensure that the upper shell does not move downward. In this state, the nozzle of the spray bottle only extends 8mm-10mm from the upper shell to avoid accidental injury to the patient due to excessive extension, and the self-locking function will not be triggered by mistake in this state.

[0048] State 2: Pre-pressed state. Figure 9 As shown, rotate the upper shell. When the raised dot on the upper shell aligns with the recessed groove in the lower shell, a click sound is heard, indicating unlocking. The latch in the upper cover engages the operating groove, allowing the upper shell to move downward until it contacts the pressing boss on the spray bottle, completing the pre-pressing process. The spring automatically rebounds the upper shell to its original height. This position allows the spray bottle nozzle to be fully extended and inserted into the nasal cavity before spraying liquid dressings.

[0049] State 3: Press spray state. Figure 10 As shown, after the pre-pressed state, the nozzle in the spray bottle is extended into the nasal cavity, and the upper shell is continued to be pressed. At this time, the pressing boss of the spray bottle contacts the upper shell and is pressed, and the nozzle of the spray bottle sprays out the liquid dressing.

[0050] When not in use, this spray bottle locks itself, preventing misuse. The nozzle of the spray bottle protrudes only 8-10 mm from the exterior of the upper shell, ensuring it won't poke children. When in use, the upper shell is rotated to unlock the protective device. A preliminary press is required to access the spray bottle, and further pressure is required to release the spray. This effectively prevents liquid dressings from being squeezed out when not in use, thus avoiding waste. The dust cover also prevents contamination of the nozzle when not in use, significantly improving the usability of the liquid dressing.
