Description

Technical Field

[0001] This utility model belongs to the field of infusion needles, specifically relating to a stent and an infusion needle assembly. Background Technology

[0002] Infusion needles are a commonly used medical device, mainly consisting of a needle and an infusion tubing. The tubing is connected to the end of the needle, which can be inserted into the body, while the tubing delivers medication to the needle. In high-dose subcutaneous injection scenarios, due to the large total amount of medication to be injected (e.g., 15 ml) and the long injection time, infusion needles are increasingly being used for subcutaneous injections.

[0003] When using an infusion needle for large-dose subcutaneous injections, the needle must first be paired with a microinfusion pump and inserted subcutaneously. The microinfusion pump then delivers the medication into the body. The combination of the infusion needle and the microinfusion pump significantly reduces the workload for healthcare workers.

[0004] However, subcutaneous injections require the injection to be performed at an angle. When a conventional IV needle is inserted into the skin, the IV tubing often droops down towards the skin due to gravity, causing the needle to tilt and making it impossible to maintain the angled position for the injection. Utility Model Content

[0005] This invention provides a support, the purpose of which is to solve the problem that the infusion needle cannot be kept in an inclined state when performing large-dose subcutaneous injections.

[0006] To achieve the above objectives, the present invention provides a support, including a support portion and a through groove. The bottom of the support portion is used to contact the skin, and the through groove is constructed on the top of the support portion and is inclined.

[0007] The inner wall of the through channel is constructed with a constraint groove, which is parallel to the through channel and is used to accommodate and fix the infusion tube.

[0008] In this design, when using an infusion needle for subcutaneous injection, the infusion tubing can be accommodated within the through-channel, keeping it in an inclined position. When the infusion tubing is in this inclined position, the infusion needle is also in an inclined position, thus meeting the requirements for subcutaneous injection when tilted.

[0009] Preferably, in order to meet the needs of subcutaneous injection, the inclination angle of the channel is 30 degrees.

[0010] The preferred design is to set the inclination angle of the infusion groove to 30 degrees. When the infusion groove is at 30 degrees and the infusion tube is accommodated inside the groove, the infusion tube causes the infusion needle to tilt at 30 degrees, thereby meeting the needs of subcutaneous injection.

[0011] Preferably, for ease of use, the constraint grooves in this solution are configured as at least two, and are arranged side by side inside the through groove.

[0012] This solution has at least two constraint slots, which can lock the infusion tube into the other constraint slots if any one constraint slot is damaged.

[0013] To ensure a more secure fixation of the infusion tube, the constraint groove and the through groove in this design are of the same length.

[0014] In this design, the constraint groove and the through groove are of the same length. Compared to setting the length of the constraint groove to be less than the length of the through groove, the constraint groove provides a better fixation effect for the infusion tube.

[0015] Preferably, in order to accommodate infusion tubes of different sizes, the diameter of the constraint groove in this scheme is different.

[0016] In this design, the diameter of the constraint groove is set to be different, so infusion tubes of different sizes can be inserted into the constraint grooves of different sizes, making it more practical.

[0017] Preferably, the through groove is an arc-shaped groove.

[0018] Since the infusion tube is a circular pipe, this solution preferably uses an arc-shaped constraint groove to fit the infusion tube. The infusion tube can be secured inside the arc-shaped constraint groove, thus keeping the infusion tube stable.

[0019] Preferably, the support portion in Scheme 1 is a support block;

[0020] Alternatively, the support portion described in Option 2 is a support sheet.

[0021] Preferably, in order to make the bracket more stable, the bottom of the bracket body in this solution is provided with an adhesive layer.

[0022] This design uses an adhesive layer to secure the stent to the skin surface, thus making the stent more stable. When the stent is stable, the infusion tubing that mates with it will also be more stable.

[0023] Preferably, since the stent needs to come into contact with the skin, a buffer layer is provided at the bottom of the stent body in this solution to reduce discomfort to the human body.

[0024] This solution uses a buffer layer to contact the skin, making the contact point between the skin and the stent more comfortable and alleviating discomfort caused by the contact between the stent and the skin.

[0025] The second aspect of this utility model discloses an infusion needle assembly, including the aforementioned bracket, needle, and infusion tube, wherein the needle is connected to the infusion tube, and the infusion tube is installed in the constraint groove of the bracket.

[0026] Preferably, in order to deliver the medication to the infusion tubing, this solution also includes a micro-injection pump, which is connected to the infusion tubing.

[0027] The beneficial effects of this utility model are as follows:

[0028] First, when using an infusion needle for subcutaneous injection, the infusion tubing can be accommodated within the channel, keeping it in an upturned position. When the infusion tubing is in this upturned position, the infusion needle is also in an upturned position, thus meeting the requirements for subcutaneous injection when tilted.

[0029] Second, when the infusion tube is inside the through groove, the infusion tube is locked in place by the limiting groove, which keeps the infusion tube in a stable state and prevents the infusion tube from shaking. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0037] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0038] Example 1

[0039] The basics are as follows: Figure 1 To be continued Figure 3 As shown, a support includes a support portion 1 and a through groove 2. The support portion 1 is block-shaped, preferably trapezoidal. The support portion 1 is preferably made of plastic to reduce weight. The bottom of the support portion 1 is for contact with the surface of human skin, while the top of the support portion 1 is provided with the through groove 2. The through groove 2 extends from one end of the support portion 1 to the other end. The through groove 2 is also inclined.

[0040] To meet the needs of subcutaneous injection, the tilt angle of the through groove 2 is preferably 30 degrees. Of course, in some other embodiments, the tilt angle of the through groove 2 can also be set to other angles. For example: tilt 15 degrees, tilt 20 degrees, tilt 25 degrees, tilt 35 degrees, tilt 40 degrees, tilt 45 degrees, tilt 50 degrees, tilt 55 degrees, or tilt 60 degrees, etc.

[0041] In this embodiment, the through groove 2 is preferably an arc-shaped groove, and a constraint groove 3 is provided on the inner wall of the through groove 2. The length of the constraint groove 3 is the same as the normal length, and the constraint groove 3 is parallel to the through groove 2. In order to adapt to the infusion tube 6, the constraint groove 3 is also preferably set as an arc-shaped groove. At the same time, in this embodiment, multiple constraint grooves 3 are preferably provided, and the constraint grooves 3 are arranged side by side on the inner wall of the through groove 2. Different constraint grooves 3 have different diameters, so they can be adapted to infusion tubes 6 of different sizes.

[0042] Taking one application scenario as an example: During subcutaneous injection, the infusion tube 6 is secured inside the restraint groove 3. The restraint groove 3 constrains the infusion tube 6, keeping it in a stable state. Furthermore, when the size of the infusion tube 6 varies, it can be secured inside restraint grooves 3 of different sizes.

[0043] To alleviate discomfort caused by contact between the support part 1 and human skin, a buffer layer 4, which can be a foam layer, is provided at the bottom of the support part 1. Simultaneously, to ensure greater stability of the support part 1, an adhesive layer is also provided at the bottom of the support part 1. This adhesive layer can be adhered to human skin, maintaining the stability of the support part 1. The adhesive layer can be positioned below the buffer layer 4.

[0044] To improve the fit between the support part 1 and the human body, the bottom of the support part 1 can be made into an arc shape, specifically a rounded arc. The arc-shaped bottom of the support part 1 can better conform to the contours of the human body.

[0045] The specific usage procedure is as follows: When a subcutaneous injection is required using an infusion needle, the medical staff first inserts the infusion needle into the body. The stent is then placed on the skin, and the infusion tube 6 is secured within the constraint groove 3 of the stent. The stent supports the infusion tube 6, which is in an inclined position. When the infusion tube 6 is in an inclined position, it causes the needle 5 to tilt upwards, allowing the medication to be delivered into the body at an angle.

[0046] Example 2

[0047] In Embodiment 1, because the support part 1 is block-shaped, its overall weight is relatively heavy, and the manufacturing cost is also high, making it inconvenient for widespread use. To solve the above problems, such as... Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the support portion 1 is a support sheet. The support sheet is bent to form the support portion 1, and the interior of the support portion 1 is hollow. The support sheet can be a metal sheet or a plastic sheet.

[0048] Example 3

[0049] The difference between this embodiment and Embodiment 1 is that, in order to make the support part 1 more stably placed on the skin surface, this embodiment preferably has straps on both sides of the support part 1. The straps on both sides can bind the support part 1 to the arm or thigh of the human body, so that the support part 1 remains stable.

[0050] Example 4

[0051] This embodiment is an improvement on Embodiment 1 to avoid damage to the infusion tubing. For example... Figure 5 As shown, in this embodiment, the preferred support portion 1 includes a fixing portion 11 and a mating portion 12, which are connected by adhesive. The bottom of the fixing portion 11 is for contact with the skin, and the fixing portion 11 can be made of metal. The mating portion 12 is disposed above the fixing portion 11, and the through groove 2 and the constraint groove 3 are both disposed on the top of the mating portion 12. The mating portion 12 can be made entirely of silicone. Therefore, when the mating portion 12 is made of silicone, the infusion tube is less likely to be scratched and damaged when it is fixed with the constraint groove 3, which helps to protect the infusion tube.

[0052] Example 5

[0053] This embodiment provides an infusion needle assembly, which includes a support, a needle 5, an infusion tubing 6, and a micro-infusion pump as described in Embodiment 1. The needle 5 is a metal needle, and the infusion tubing 6 is installed at the tail end of the needle 5, supplying medication to the needle 5. Simultaneously, the infusion tubing 6 is engaged within the constraint groove 3 of the support, ensuring a connection between the support and the infusion tubing 6.

[0054] The micro-injection pump in this embodiment is a prior art micro-injection pump that can deliver medication precisely, in minute quantities, uniformly, and continuously. The outlet of the micro-injection pump is connected to the infusion tubing 6, allowing the pump to deliver the medication to the tubing. The medication then flows along the tubing 6 to the needle 5 and enters the body through the needle.

[0055] To make the infusion needle more stable, after the needle 5 is inserted into the human body and the infusion tube 6 is secured to the stent, the stent and the infusion tube 6 can be wrapped with gauze to the human arm or thigh, thereby making the needle more stable and further improving the stability of the needle 5.

[0056] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
