Description

Technical Field

[0001] The utility model belongs to the technical field of medical consumables, and in particular relates to an anti-opening disposable sample liquid storage bottle. Background Art

[0002] In the field of medical testing, sample storage bottles are a commonly used consumable. Sample storage bottles generally include a tubular bottle body, and the bottle mouth is screwed on with a screw cap. After the medical staff collects the patient's liquid sample, the sample is injected into the bottle body and then the screw cap is screwed on. There is a QR code label on the surface of the bottle body, and the sample storage bottle is sent to the laboratory for testing and other operations.

[0003] Before the laboratory staff conducts the test, they need to ensure that the sample storage bottle is not opened. First, to prevent the screw cap from loosening and causing sample leakage, and second, to prevent the sample from being swapped or contaminated after the screw cap is opened. Although this probability is low in the current medical environment, the safety of samples from more important patients still needs to be ensured. Ordinary sample storage bottles are difficult to meet this condition. Even if the screw cap of this conventional structure sample storage bottle is opened and then covered, it is difficult to be discovered, which poses obvious hidden dangers. Utility Model Content

[0004] In view of the above problems, the purpose of the present utility model is to provide a disposable sample storage bottle that is resistant to opening, aiming to solve the above technical problems.

[0005] The utility model adopts the following technical solutions:

[0006] The anti-opening disposable sample storage bottle includes a bottle body and a screw cap, the bottle body is threadedly connected to the screw cap, the neck of the bottle body is provided with a circle of slots, one side of the slots is a sloped surface, and the other side is a vertical surface, the screw cap and the corresponding position of each slot are integrally formed with a hook, the hook includes a connecting portion and an inwardly protruding resistance portion, one side of the resistance portion is an inclined surface, and the other side is a vertical surface, and the length of the slot is greater than the length of the resistance portion.

[0007] Furthermore, a sealing rubber plug is arranged inside the rotary cover, a circular arc groove is arranged on the top surface of the rotary cover and a lifting plate is formed thereon, and a notch is arranged on the edge of the circular arc groove.

[0008] Furthermore, the bottom of the bottle body has a countersunk mouth, and the bottom of the bottle body also has a straight groove.

[0009] Furthermore, there is an information label on the surface of the bottle.

[0010] The beneficial effect of the utility model is as follows: in the sample liquid storage bottle, a relatively long groove is arranged on the neck of the bottle body, and the two sides of the groove are respectively arranged as a slope and a vertical surface, and a corresponding hook is arranged on the outer periphery of the bottom of the screw cap, and the two side surfaces of the resistance part of the hook correspond to the slope and the vertical surface respectively. In this way, in the process of screwing in the screw cap, the hook of the screw cap cyclically shifts in the groove of the bottle body, which does not affect the tightening of the screw cap, and limits the rotation direction of the screw cap. The screw cap cannot rotate in the opposite direction, and the screw cap can only be opened by destroying the hook. Therefore, through this structural design, the anti-opening effect is achieved, and the safety of the liquid storage bottle is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0018] like Figure 1-3 As shown, the anti-opening disposable sample storage bottle provided in this embodiment includes a bottle body 1 and a screw cap 2, and the bottle body 1 is threadedly connected to the screw cap 2. Figure 4 As shown, the neck of the bottle body 1 is provided with a circle of grooves 3, one side of the grooves 3 is a sloped surface 31, and the other side is a vertical surface 32. The screw cap 2 and the corresponding position of each groove 3 are integrally formed with a hook 4, and the hook 4 includes a connecting portion 41 and an inwardly protruding abutting portion 42, one side of the abutting portion 42 is an inclined surface 421, and the other side is a vertical surface 422, and the length of the groove 3 is greater than the length of the abutting portion 42.

[0019] In this structure, as shown in the figure, there are 10 slots and hooks. When the cover is turned, the abutment part will fall into the slot. When the cover is turned, the inclined surface of the abutment part contacts the slope of the slot, and the abutment part will smoothly detach from the slot, so it will not affect the rotation of the cover. When the cover is finally tightened, the abutment part falls into the slot. Since the vertical surface of the abutment part contacts the vertical surface of the slot, the cover cannot be turned in the opposite direction, thereby achieving an anti-opening effect and ensuring the safety of the sample in the bottle. In this structure, the length of the slot is greater than the length of the abutment part, so that the downward movement of the abutment part can be ensured during the rotation of the cover.

[0020] If you want to force open the screw cap, you can only destroy each hook, causing deformation. Because there are many hooks and the hooks are elastic, it is difficult to operate and push the hooks outward at the same time. Therefore, the safety of this structure is very high.

[0021] In this structure, the screw cap 2 has a sealing rubber plug 5, the top surface of the screw cap 2 has an arc groove and a peeling plate 6, and the edge of the arc groove has a notch 21. During the inspection, the inspector directly peels off the peeling plate from the notch. The peeling plate is made of plastic or aluminum. After the sealing rubber plug is exposed, a syringe is inserted into the plug to complete the sampling inspection. There is also an information label 13 on the surface of the bottle body 1 to distinguish different samples.

[0022] Since the liquid storage bottles are placed in the test box, the bottom of the bottle body 1 has a countersunk mouth 11, and the bottom of the bottle body 1 also has a straight groove 12. By setting a card strip in the test box and inserting the straight groove on the card strip, the position of the sample liquid storage bottle can be limited to avoid the samples in the box being messy.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
