Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a positioning plate for subcutaneous injection around the umbilicus. Background Art

[0002] Insulin injections have been widely used in clinical practice as an effective treatment for diabetes. Insulin is a hormone secreted by the pancreas and is essential for regulating blood sugar levels in the human body. In patients with diabetes, insulin injections can help control blood sugar and prevent and reduce the occurrence of complications. In hospitals, insulin injections are usually performed by professional medical staff. Since patients with diabetes usually need to inject insulin regularly, medical staff need to master injection techniques accurately to ensure that the drug can enter the body accurately and quickly.

[0003] During the injection process, the insulin injection site can generally be repeated at least once a week. Positioning is an extremely critical step, and repeated injections at the same site should be avoided to prevent subcutaneous tissue damage and fat atrophy. However, in actual work, due to the handover of medical staff, in order to repeat the injection, medical staff need to carefully hand over the injected site, but there is still a risk of repeated injections just through handover. Utility Model Content

[0004] The utility model aims to provide a positioning disc for subcutaneous injection around the umbilicus, which is attached to the abdomen of the patient through a flexible positioning disc, and insulin is injected from the injection positioning hole. Each time an injection is made, a patch covering the hole needs to be torn off, which can effectively avoid repeated injections.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a positioning disc for subcutaneous injection around the umbilicus, comprising a flexible positioning disc, a umbilicus positioning hole is opened at the center of the flexible positioning disc, a plurality of injection positioning holes distributed in a circle are opened at the edge of the flexible positioning disc, a covering patch with glue on one side is pasted at each injection positioning hole at the upper end of the flexible positioning disc, a plurality of flexible connecting sheets are arranged at the edge of the flexible positioning disc, a plurality of suction cups are arranged at the lower end of each flexible connecting sheet, a negative pressure flattening tube with elasticity is arranged at the upper end of each flexible connecting sheet, each suction cup is connected to the corresponding negative pressure flattening tube, a one-way valve is arranged at the upper end of each negative pressure flattening tube, and each one-way valve is opened toward the inside of the negative pressure flattening tube and closed otherwise.

[0006] By adopting the above technical solution, when using, align the flexible positioning disc with the navel positioning hole with the patient's navel as the center, make the two flexible connecting sheets close to the two sides of the patient's abdomen respectively, press the negative pressure flat tube to squeeze the gas inside from the one-way valve, so that the suction cup generates negative pressure to suck the patient's skin, complete the positioning, and then the next perforated patch is placed to inject insulin through the injection positioning hole. After the injection is completed, tear off the flexible positioning disc. For the next injection, after sticking the flexible positioning disc on the patient's abdomen, tear off the next perforated patch clockwise or counterclockwise for injection, so as to avoid repeated injection positions.

[0007] The utility model is further configured as follows: a hand-pull strip without glue is provided at the edge of each cover-hole patch.

[0008] The utility model is further configured as follows: the negative pressure flattened tube is a corrugated flexible plastic tube.

[0009] The utility model is further configured as follows: a V-shaped rubber valve membrane with the tip facing upward is arranged in the one-way valve, and a hole is opened at the tip of the rubber valve membrane and is closed due to its elasticity under normal conditions.

[0010] The utility model is further configured as follows: a hard pressing sheet is provided at the upper end of the negative pressure flat tube.

[0011] In summary, the utility model has the following beneficial effects:

[0012] First, the utility model can effectively avoid repeated injections by attaching a flexible positioning disc to the patient's abdomen and injecting insulin from the injection positioning hole. Each injection is performed by tearing off a patch with holes in a clockwise or counterclockwise order.

[0013] Secondly, the utility model presses the negative pressure flat tube to make the suction cup generate enough suction to suck the patient's abdomen, so that the flexible positioning disc sticks to the patient's abdomen. When using the flexible positioning disc for positioning injection, no hand support is required, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
