Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an indwelling needle limiting and fixing device. Background Technology

[0002] An indwelling catheter (also known as a peripheral venous catheter) is a small plastic tube inserted into a patient's vein to deliver medications, fluids, or draw blood samples. A heparin cap is a small cap containing heparin solution, attached to the end of the indwelling catheter. Heparin is an anticoagulant that prevents blood from clotting inside the catheter and forming a blood clot. When healthcare professionals need to administer medication or draw blood through the indwelling catheter, they open the heparin cap to perform the procedure and then close it again to maintain the system's closed and sterile state.

[0003] In the current technology, medication is usually administered manually by medical staff through indwelling needles. With the development of technology, in order to reduce manpower consumption, scenarios have emerged where medication is administered automatically by robotic arms.

[0004] In automated drug delivery scenarios using robotic arms, especially for radiopharmaceuticals, the connector between the intravenous catheter and the heparin cap needs to be properly secured to ensure stable and safe drug delivery. An unstable connector can lead to several problems: loose connectors can cause fluid leakage, affecting the accuracy of the infusion dosage; unstable connectors can also cause blood to clot in the area, forming a thrombus. Therefore, a connector securing device is required. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0045] This utility model relates to a device for limiting and fixing indwelling needles.

[0046] It includes a fixed male end 1 and a fixed female end 2, which cooperate to form a limiting channel to fix the connector.

[0047] In this invention, the limiting access connector is clamped by setting a fixed male end 1 and a fixed female end 2 to fix the connector, thereby ensuring the stability of the heparin cap position when the robotic arm automatically administers the drug, and ensuring the smooth completion of the drug delivery process.

[0048] In this specific embodiment, the fixed male end 1 and the fixed female end 2 can be achieved by the magnetic sheet of this application, or by snap-fit, or by hinge and buckle, or by adhesive bonding, or by binding with rubber strips.

[0049] When achieved through a hinge and a snap fastener, the hinge is located on one side of the fixed male end 1 and the fixed female end 2, and is connected to the fixed male end 1 and the fixed female end 2. The snap fastener is located on the other side of the fixed male end 1 and the fixed female end 2, and keeps the fixed male end 1 and the fixed female end 2 in a close-fitting state.

[0050] Optionally, the fixed male end 1 is provided with a first limiting groove, and the fixed female end 2 is provided with a second limiting groove. By fitting the fixed male end 1 and the fixed female end 2 together, the first limiting groove and the second limiting groove form the limiting channel.

[0051] This utility model generates a limiting channel by setting a limiting groove, which facilitates the placement and replacement of the connector, making the overall connector fixing device more convenient and quick to use.

[0052] Optionally, the first limiting groove and the second limiting groove are the same size and shape, and are respectively disposed inside the fixed male end 1 and the fixed female end 2 in a mirror image of the vertical plane.

[0053] In this invention, the two grooves are designed to have the same shape. Since the channel of the connector has a cylindrical structure, the two grooves with the same shape can easily and smoothly place the connector into the limiting groove, thereby fixing the connector.

[0054] In this specific embodiment, the shapes of the first limiting groove and the second limiting groove may be different. The limiting channel portion of the second limiting groove is larger than the limiting channel portion of the first limiting groove. The material of the fixing female end 2 is set as soft plastic. Since the second limiting groove is set on the fixing female end 2, the connector can be pressed into the second limiting groove formed by the soft plastic, so that the second natural part can form a local clamping effect on the connector, making the fixing effect of the connector better.

[0055] Optionally, a movable connection device is also provided between the fixed male end 1 and the fixed female end 2.

[0056] In this utility model, the movable connection between the fixed male end 1 and the fixed female end 2 facilitates the placement and replacement of the connector.

[0057] Optionally, the movable connecting device is a male magnet and a female magnet 5, which are located on the two end faces of the fixed male end 1 and the fixed female end 2 respectively.

[0058] In this invention, the attraction effect of a magnet is used to achieve a movable connection between the fixed male end 1 and the fixed female end 2. When it is necessary to make the fixed male end 1 and the fixed female end 2 fit together, the fixed male end 1 is brought close to the fixed female end 2, and the attraction effect of the magnet allows them to maintain a fitted state.

[0059] Optionally, the movable connecting device is a female end magnet 5, which is located on the fixed female end 2 and on the end face where the fixed male end 1 and the fixed female end 2 are attached. The end face material of the fixed male end 1 where the fixed male end 1 and the fixed female end 2 are attached is a ferromagnetic material.

[0060] In this invention, the attraction effect of a magnet is used to achieve a movable connection between the fixed male end 1 and the fixed female end 2. When it is necessary to make the fixed male end 1 and the fixed female end 2 fit together, the fixed male end 1 is brought close to the fixed female end 2. The fixed male end 1, which is made of ferromagnetic material, is attracted by the magnet sheet, so that the fixed male end 1 is kept in contact with the fixed female end 2.

[0061] Optionally, a positioning device is also provided between the fixed male end 1 and the fixed female end 2.

[0062] In this invention, a positioning device is provided to limit the corresponding positions of the fixed male end 1 and the fixed female end 2, thereby preventing displacement between the fixed male end 1 and the fixed female end 2.

[0063] Optionally, the positioning device includes a guide post 3 and a guide hole 4. The guide post 3 is disposed on the fixed female end 2 and located on the end face where the fixed male end 1 and the fixed female end 2 are fitted together. The guide hole 4 is disposed on the fixed male end 1 corresponding to the position of the guide post 3 and located on the end face where the fixed male end 1 and the fixed female end 2 are fitted together. The number of guide posts 3 and guide holes 4 is multiple.

[0064] In this invention, the guide post 3 and guide hole 4 not only provide a positioning effect, but also enhance the bonding strength between the fixed female end 2 and the fixed male end 1 due to the friction generated between the guide post 3 and guide hole 4.

[0065] Optionally, the bottom surface formed by the fixed male end 1 and the fixed female end 2 is parallel to the horizontal plane.

[0066] In this invention, the bottom is parallel to the horizontal plane, ensuring the stable installation of the overall fixing device.

[0067] Example 1:

[0068] like Figures 1-6As shown, based on the above technical solution, the connector in this embodiment 1 is a Y-shaped connector, and the limiting channel is a Y-shaped channel corresponding to the Y-shaped connector.

[0069] The installation process for the Y-shaped connector is as follows:

[0070] Firstly, the fixed male end 1 is provided with a Y-shaped first limiting groove 101, and the fixed female end 2 is provided with a Y-shaped second limiting groove 201. Both the first and second limiting grooves are Y-shaped to form a Y-shaped channel. The first and second limiting grooves are the same size and shape, and are mirror images of each other, located inside the fixed male end 1 and the fixed female end 2, respectively. Since the outer surface of the Y-shaped connector has a double-cylinder structure, the two grooves of the same shape are located exactly at the diameter of the cylinder, allowing the connector to be easily and smoothly placed into the limiting groove, thus realizing the placement of the Y-shaped connector.

[0071] After the Y-shaped connector is placed, the male end 1 and the female end 2 are brought close together for contact. The female end 2 is equipped with a female magnet 5, located on the contact surface of the male end 1 and the female end 2. The male end 1 is made of a ferromagnetic material, such as iron or stainless steel. The male end 1 is attracted by the female magnet 5, thus clamping and fixing the Y-shaped connector. Then, guide posts 3 and guide holes 4 are placed between the male end 1 and the female end 2. The guide posts 3 are located on the female end 2 and on the contact surface of the male end 1 and the female end 2. The guide holes 4 are located on the male end 1, corresponding to the guide posts 3, and on the contact surface of the male end 1 and the female end 2. There are two guide posts 3 and two guide holes 4. When the fixed male end 1 and the fixed female end 2 are brought close together for bonding, the guide post 3 enters the guide hole 4, which not only positions the fixed male end 1 and the fixed female end 2, but also strengthens the bonding strength between the fixed female end 2 and the fixed male end 1 due to the friction generated between the guide post 3 and the guide hole 4.

[0072] When replacing the Y-type connector, since the fixed male end 1 and the fixed female end 2 are attached and fixed by magnetism, the fixed male end 1 and the fixed female end 2 are separated by external force, the Y-type connector clamped in the Y-shaped channel is taken out, and then the new Y-type connector is put into the Y-shaped channel to complete the replacement of the Y-type connector.

[0073] Example 2:

[0074] like Figures 7-12As shown, based on the above technical solution, the connector in this embodiment 2 is a straight connector, and the limiting channel is a straight channel corresponding to the straight connector.

[0075] The installation process for straight connectors is as follows:

[0076] Firstly, the fixed male end 1 is provided with a straight first limiting groove 102, and the fixed female end 2 is provided with a straight second limiting groove 202. Both the straight first limiting groove 102 and the second limiting groove are straight, forming a straight channel. The straight first limiting groove 102 and the straight second limiting groove 202 are the same size and shape, and are respectively arranged inside the fixed male end 1 and the fixed female end 2, mirror images of the vertical plane. Since the outer surface of the straight connector has a double-cylinder structure, the two grooves of the same shape are located exactly at the diameter of the cylinder, which allows the connector to be easily and smoothly placed into the limiting groove, thus realizing the placement of the straight connector.

[0077] After the straight connector is placed, the male end 1 and the female end 2 are brought close together for contact. The female end 2 is equipped with a female magnet 5, located on the contact surface of the male end 1 and the female end 2. The male end 1 is made of a ferromagnetic material, such as iron or stainless steel. The male end 1 is attracted by the female magnet 5, thus clamping and fixing the straight connector. Then, guide posts 3 and guide holes 4 are placed between the male end 1 and the female end 2. The guide posts 3 are located on the female end 2 and on the contact surface of the male end 1 and the female end 2. The guide holes 4 are located on the male end 1, corresponding to the guide posts 3, and on the contact surface of the male end 1 and the female end 2. There are two guide posts 3 and two guide holes 4. When the fixed male end 1 and the fixed female end 2 are brought close together for bonding, the guide post 3 enters the guide hole 4, which not only positions the fixed male end 1 and the fixed female end 2, but also strengthens the bonding strength between the fixed female end 2 and the fixed male end 1 due to the friction generated between the guide post 3 and the guide hole 4.

[0078] When replacing a straight connector, since the fixed male end 1 and the fixed female end 2 are magnetically attached and fixed, the fixed male end 1 and the fixed female end 2 are directly separated by external force, the straight connector clamped in the straight channel is taken out, and then the new straight connector is put into the straight channel to complete the replacement of the straight connector.

[0079] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of disclosure involved in this utility model is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described concept.
