[0015] Compared with the prior art, the utility model has at least the following beneficial effects:
[0016] In the above solution, by providing the clamping and limiting mechanism, the bottom of the infusion bag body and the top of the needle body can be quickly limited. When the patient turns over and accidentally pulls the infusion tube, the needle body will not be pulled off from the bottom of the infusion bag body. And when the needle body is in use, there is always a force pushing it towards the infusion bag body, so that the connection between the needle body and the bottom of the infusion bag body is closely fitted during use. The mechanism prevents the device from loosening or falling off, and is convenient and fast to install and use.
[0017] By providing a clamping block in the clamping and limiting mechanism, and the clamping block and the limiting block provided thereon, the clamping block is opened by pressing the first pressing piece by hand, so that the limiting block is clamped at the uneven part at the bottom of the needle body, and the limiting block and the clamping block cooperate to limit and fix the bottom of the infusion bag body. The fixing effect is better, and the structure is applicable to infusion bag bodies of various models.
[0018] By providing a connecting block in the clamping and limiting mechanism, a force can be created between the clamping block and the card block fixedly connected at both ends of the connecting block to tighten the center position of the connecting block, so that the clamping block and the card block always remain close to each other during use, so that the connection between the needle body and the infusion bag body is always squeezed and pressed tightly, and the structure further improves the limiting effect of the clamping and limiting mechanism.

[0036] As Figures 1 to 6 As shown, an embodiment of the present utility model provides an infusion safety anti-detachment mechanism, including an infusion bag body 1, a needle body 2 is installed at the bottom of the infusion bag body 1; a clamping and limiting mechanism for preventing the needle body 2 from detaching, the clamping and limiting mechanism is connected to the infusion bag body 1, the bottom of the connecting block 6 is fixedly connected to the outer wall of the clamping block 8, a set of clamping blocks 3 are integrally formed with the connecting block 6, the support block 7, the clamping block 8 and the second pressing block 9, the clamping blocks 3 are two and connected into one body through a connecting member, a limiting block 5 is fixedly connected to the inner wall of each of the set of clamping blocks 3 respectively, the second pressing block 9 is in an inclined shape adapted to the thumb of the hand, and a small groove is provided on the side of the second pressing block 9 away from the clamping block 8. By adjusting the clamping and limiting mechanism, the clamping blocks 3 and the clamping block 8 in the clamping and limiting mechanism can be quickly fixed on the infusion bag body 1 and the needle body 2, so that the clamping and limiting mechanism generates a force that tightens towards the center of the two on the infusion bag body 1 and the needle body 2, making the connection between the infusion bag body 1 and the needle body 2 relatively tight during use. When the needle body 2 is subjected to a downward pulling force, the connecting block 6 connects the clamping blocks 3 and the clamping block 8, and the clamping block 8 limits the top of the needle body 2, so that the needle body 2 will not be detached from the bottom of the infusion bag body 1 under the action of the pulling force.
[0037] As Figures 1 to 6As shown in the figure, the clamping and limiting mechanism includes a clamping block 3 installed on the infusion bag body 1. A connecting block 6 is fixedly connected to the bottom of a group of clamping blocks 3. A clamping block 8 is fixedly connected to the bottom of the connecting block 6. First pressing pieces 4 are fixedly connected to the bottoms of both groups of clamping blocks 3. The first pressing pieces 4 are wider at the top and narrower at the bottom, and the outer wall edge of the first pressing piece 4 is arc-shaped. Anti-slip blocks are provided on the outer wall of the clamping block 3 near the first pressing piece 4, and the outer wall edge of the anti-slip block is arc-shaped. A clamping groove adapted to the shape of the bottom of the infusion bag body 1 is formed in the clamping block 3. The opening of the clamping block 3 is inclined inwards. A limiting block 5 is fixedly connected to the side wall of the clamping block 3. A groove adapted to the shape of the convex block at the bottom of the infusion bag body 1 is formed in the inner wall of the limiting block 5. The surface of one end of the limiting block 5 near the opening of the clamping block 3 is a slope. Through the setting of the first pressing piece 4, the contact surface between the clamping block 3 and the hand can be increased, making the clamping block 3 easier to open, so as to clamp the clamping block 3 on the infusion bag body 1, and enabling the limiting block 5 in the clamping block 3 to produce a good limit on the bottom of the infusion bag body 1. Moreover, the groove on the limiting block 5 matches the shape of the bottom of the infusion bag body 1, making the limiting and clamping effect of the clamping block 3 on the infusion bag body 1 better. And the groove inside the limiting block 5 matches the convex block at the bottom of the infusion bag body 1, further strengthening the limiting effect of the clamping block 3 on the infusion bag body 1. And the inclined shape at the opening of the limiting block 5 facilitates the infusion bag body 1 to slide into the limiting block 5 along the slope of the limiting block 5.
[0038] As Figures 1 to 6 shown, the connecting block 6 is in a "C" shape, the outer wall of the connecting block 6 is arc-shaped. A supporting block 7 is fixedly connected to the side wall of the connecting block 6. The supporting block 7 is in an inverted "C" shape, and the hardness of the supporting block 7 is greater than that of the connecting block 6. The shape formed by the connecting block 6 and the supporting block 7 is adapted to the shape formed after the human hand is bent. A second pressing block 9 is fixedly connected to the bottom of the connecting block 6. The second pressing block 9 is oval-shaped, and an anti-slip pad is provided on the outer wall surface of the second pressing block 9. A groove adapted to the shape of the needle body 2 is formed inside the clamping block 8. The opening of the clamping block 8 is outwardly expanding. Through the shape design of the connecting block 6 and the supporting block 7, the toughness and strength of the connecting block 6 and the supporting block 7 are better, and at the same time, it is adapted to the shape of the hand. When in use, it is convenient for the user to hook the supporting block 7 with a finger, and then quickly fix the clamping block 3 and the clamping block 8 on the infusion bag body 1 and the needle body 2 respectively. And the setting of the second pressing block 9 facilitates pressing the second pressing block 9 with the thumb of the finger to quickly push the clamping block 8 towards the needle body 2, so that the clamping block 8 is quickly installed on the needle body 2. And the shape setting of the second pressing block 9 is adapted to the thumb, preventing the problem of side slip from occurring during the operation process.
[0039] The working principle of the technical solution provided by the utility model is as follows: when in use, the infusion bag body 1 is first hung at a high place, and then the upper needle of the needle body 2 is inserted and fixed on the bottom of the infusion bag body 1, and then the lower needle of the needle body 2 is inserted on the human skin, and then two fingers are used to hook the support block 7, and the connection block 6 limits the fingers. After the clamping limit mechanism is moved to the connection between the infusion bag body 1 and the needle body 2, the clamping block 3 and the first pressing piece are clamped with the thumb and index finger. 4 is pressed to open the opening of the clamping block 3, and the limiting block 5 is aligned with the concave and convex part of the bottom of the infusion bag body 1, so that the infusion bag body 1 slides into the groove of the limiting block 5 along the inclined surface of the limiting block 5, and then the clamping block 3 and the first pressing piece 4 are released to reset the clamping block 3 and the limiting block 5, so that the clamping block 3 and the limiting block 5 are quickly and stably clamped and fixed at the bottom of the infusion bag body 1, and then the second pressing block 9 is pressed with the fingertips to push the clamping block 8 toward the needle body 2, and the other The needle body 2 is limited by one finger, so that the needle body 2 quickly slides into the clamping block 8 along the inclined surface of the clamping block 8, so that the clamping block 8 is quickly clamped and fixed on the needle body 2. In addition, most of the existing infusion bag bodies 1 and needle bodies 2 have small protrusions themselves. The coordinated use of the clamping block 3, the connecting block 6 and the clamping block 8 can stably connect the infusion bag body 1 and the needle body 2 together. When the needle body 2 is subjected to a downward pulling force, the deformation effect of the connecting block 6 and the supporting block 7 thereon is cooperated, so that the connecting block 6 and the supporting block 7 have a buffering effect on the downward force, while the supporting block 7 strengthens the strength and toughness of the connecting block 6, so that it will not be broken by force. After use, you only need to hook the supporting block 7 with your fingers again, press the clamping block 3 and the first pressing piece 4, open the clamping block 3, separate the limiting block 5 and the infusion bag body 1, and then move the second pressing block 9 to separate the clamping block 8 from the needle body 2, so that the clamping and limiting mechanism can be quickly disassembled.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiment of the present invention, and the present invention can be fully understood by those skilled in the art without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
[0041] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
