Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a puncture-free infusion bottle cap. Background Art

[0002] Intravenous infusion is a common medical method used to treat patients in the current medical field. The existing infusion bottle caps are generally sealed with rubber stoppers. In order to take the medicine, the rubber stoppers must be punctured.

[0003] However, during the puncture process, the rubber stopper is prone to shed chips, contaminating the drug solution. At the same time, the puncture chips may also block the puncture needle hole and cause infusion obstruction.

[0004] Therefore, it is a very valuable research direction to break through the existing method of taking the liquid medicine while ensuring the sealing of the liquid medicine before opening. Summary of the invention

[0005] The object of the present invention is to provide a puncture-free infusion bottle cap, which can realize the taking of liquid medicine without needle puncture.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a puncture-free infusion bottle cap, comprising a bottle cap body and an easy-folding handle arranged on the bottle cap body, a rubber plug and a card for clamping the rubber plug are arranged in the bottle cap body, the easy-folding handle comprises a connecting part directly connected to the bottle cap body and a rotatable rotating part sleeved on the connecting part, a receiving cavity for accommodating a telescopic ejector rod is arranged in the rotating part, an inner thread is provided on the inner wall of the receiving cavity, and the head of the telescopic ejector rod is arranged on an outer thread matching with the inner wall of the receiving cavity; the card is disc-shaped, and a plurality of notches are provided on its edge; a plurality of liquid flow channels are provided on the inner wall of the bottle cap body for accommodating the card; the card can rotate freely in the bottle cap body; a plurality of first oblique teeth are provided at the lower part of the rubber plug, and a plurality of second oblique teeth matching with the first oblique teeth of the rubber plug are provided on the upper surface of the card; when the first oblique teeth are pressed downward by an external force to rotate the card, the notch coincides with the liquid flow channel so that the liquid medicine can pass through the liquid flow channel freely.

[0007] Furthermore, after the rotating part is rotated, the front part of the telescopic push rod presses the plug downward so that the tooth surface of the first bevel tooth at the bottom of the plug fits with the tooth surface of the second bevel tooth of the card and forces the card to rotate. After the card rotates, the notch coincides with the liquid flow channel so that the medicine can pass freely through the liquid flow channel.

[0008] Preferably, the cavity for accommodating the card in the bottle cap body is circular.

[0009] Furthermore, a limiting structure for limiting the rotation of the telescopic top rod is provided in the connecting portion.

[0010] The beneficial effect of the present invention is that, compared with the infusion bottle cap with a rubber stopper in the prior art, the present invention can obtain liquid medicine without puncture, thereby avoiding the liquid medicine being contaminated by debris during the puncture process.

[0013] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0014] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] In addition, in the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them instead of being in direct contact. Moreover, the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature. The terms "above", "below", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention.

[0016] like Figure 1-2As shown, a puncture-free infusion bottle cap comprises a bottle cap body 5 and an easy-folding handle 1 arranged on the bottle cap body, wherein a rubber plug 3 and a card 4 for clamping the rubber plug 3 are arranged in the bottle cap body 5, wherein the easy-folding handle 1 comprises a connecting portion 1b directly connected to the bottle cap body 5 and a rotatable rotating portion 1a sleeved on the connecting portion 1b, wherein a receiving cavity 1a1 for accommodating a telescopic ejector rod 2b is arranged in the rotating portion, wherein an inner wall of the receiving cavity 1a1 is provided with an internal thread, and the head of the telescopic ejector rod is provided with an external thread matched with the inner wall of the receiving cavity; the card is disc-shaped, and a plurality of notches 4a are arranged on its edge; a plurality of liquid flow channels are arranged on the inner wall of the bottle cap body 5 for accommodating the card; the card 4 can rotate freely in the bottle cap body 5; a plurality of first oblique teeth 3a are arranged at the lower part of the rubber plug, and a plurality of second oblique teeth 4b matching the first oblique teeth 3a of the rubber plug are arranged on the upper surface of the card; when the first oblique teeth 3a are pressed downward by an external force to rotate the card 4, the notch coincides with the liquid flow channel so that the liquid medicine can freely pass through the liquid flow channel.

[0017] Furthermore, after rotating the rotating part 1a, the front part of the telescopic push rod 2b presses the plug 3 downward so that the tooth surface of the first bevel tooth 3a at the bottom of the plug fits with the tooth surface of the second bevel tooth 4b of the card 4 and forces the card 4 to rotate. After the card 4 rotates, the notch 4a coincides with the liquid flow channel so that the liquid medicine can freely pass through the liquid flow channel.

[0018] Preferably, the cavity in the bottle cap body 5 for accommodating the card 4 is circular.

[0019] Furthermore, a limiting structure for limiting the rotation of the telescopic top rod 2b is provided in the connecting portion 1b.

[0020] In the figure, an easy-to-break opening 1b1 is provided between the easy-to-break handle 1 and the bottle cap body 5.

[0021] The working principle of the present invention is that when the bottle cap needs to be opened, the rotating part 1a of the foldable handle 1 is first rotated, at which time the head 2a of the telescopic push rod 2 will move downward relative to the accommodating chamber 1a1, and the rod body 2b of the telescopic push rod 2 will also move downward to support the rubber stopper 3, and the rotating part 1a is continued to be rotated to make the rod body 2b of the telescopic push rod 2 completely unable to move downward (indicating that the first oblique tooth 3a has been against the card 4), and at this time the card 4 will inevitably rotate relative to the bottle cap body 5 to open the liquid flow channel; at this time, the user should break the foldable handle 1.

[0022] For this patent, how to cleverly set the liquid flow channel and cleverly open the liquid flow channel when the bottle cap is not opened is the core creative source of this patent. It should be said that any improvement given to this concept should be included in the scope of protection.

[0023] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.

[0024] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and for the sake of clarity, some other elements are omitted in this application document. Ordinary technicians in the field should realize that these omitted elements may also constitute the content of the present invention.
