Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a medical simulation doll with a built-in infusion port. Background Art

[0002] Implantable intravenous infusion ports (medically known as ports) are a novel infusion method for long-term infusion. They are common in developed Western countries and have begun to become popular in some parts of my country. Infusion ports are placed in the human body to reduce the stimulation of chemotherapy drugs on the patient's blood vessels. They mainly include puncture seats, catheters and butterfly needles. After the puncture seat is implanted subcutaneously, it is connected to the catheter inserted into the central vein to establish a long-term vascular channel, which can play a role similar to that of a port, so it is called an "infusion port". It is rarely used in pediatric patients because children have thin blood vessels, growth characteristics and low degree of cooperation with intravenous infusion. Infusion ports are more suitable for long-term intravenous infusion, especially for children with tumors. They help to reduce the pain of repeated punctures in children, reduce the damage to peripheral veins caused by chemotherapy drugs and irritating drugs, and improve the quality of life of children. However, invasive operations (non-invasive needle puncture) will still cause fear or burden in children and reduce their degree of cooperation. If coercive measures are taken, invasive operations can be completed quickly to a certain extent, but they will still cause strong stress reactions in children, causing physical and mental damage to them. Interest induction refers to discovering the needs of children, capturing their interests, taking advantage of the situation, and conducting basic interventions based on their psychological characteristics. Currently, the existing infusion port materials are not conducive to the development of medical games, nor can they divert children's attention and interest, nor can they eliminate the negative emotions caused by invasive operations (non-destructive needle puncture). Summary of the invention

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1-4 As shown, the medical simulation doll with a built-in infusion port 2 includes a doll body 1, wherein the doll body 1 is provided with an infusion port 2 and a fluid storage capsule 3, wherein the infusion port 2 is connected to the fluid storage capsule 3, and the doll body 1 is also provided with a non-destructive needle assembly 4 for injecting or aspirating the infusion port 2, wherein the needle tip of the non-destructive needle assembly 4 is spherical. The doll body 1 is preferably a cartoon humanoid doll with a similar color to human skin, which is more popular with children. The structure of the non-destructive needle assembly 4 is similar to that commonly seen in the art, but the needle tip is replaced with a thicker needle tip, and the needle tip is made into a spherical shape to prevent children from stabbing themselves or others when using it. The fluid storage capsule 3 is preferably made of materials such as silicone.

[0024] It is the nature of children to like games. Games can attract their attention and offset their negative emotions.

[0025] In further detail, the infusion port 2 includes a puncture seat 5 and a catheter lock 6. The puncture seat 5 is provided with a flexible puncture septum 7. The puncture seat 5 is also provided with a sample box 8. The puncture seat 5 is also provided with a suture hole for fixing on the subcutaneous tissue. The catheter lock 6 is used to connect and fix the catheter. The flexible puncture septum 7 is usually a silicone septum with a thickness of more than two centimeters, which can not only withstand multiple punctures, but also can be used to fix the needle.

[0026] In further detail, since the needle of the non-injurious needle assembly 4 is thickened, in order to facilitate the insertion of the needle of the non-injurious needle assembly 4, a plug hole 9 is provided on the flexible puncture septum 7 of the infusion port 2, and a chamfer is provided at the beginning of the plug hole 9, and the plug hole 9 is used to insert the needle of the non-injurious needle assembly 4. When the needle is inserted into the plug hole 9, since the flexible puncture septum 7 is made of silicone, it can tightly wrap the needle, and when the needle is not inserted, the plug hole 9 is in a sealed state, with only a circular groove formed by the chamfer, which can prevent the liquid reservoir 3 from flowing back out.

[0027] To further elaborate, in order to recycle and reduce costs, a patch 10 is also included, and the adhesive surface of the patch 10 is provided with Velcro. The patch 10 is used to stick on the wound after the injection of the infusion port 2 is completed to reduce infection. In this simulation doll, it is used to cover the location of the infusion port 2 and play a certain sealing role. Velcro is a prior art and will not be described here. The other half of the Velcro is attached to the doll body 1.

[0028] In further detail, the infusion port 2 and the fluid storage bag 3 are connected by a first conduit 11 and a second conduit 12. The first conduit 11 is provided with a one-way valve 13, and the one-way valve 13 is used to prevent the liquid in the fluid storage bag 3 from flowing back to the infusion port 2. The diameter of the second conduit 12 is smaller than the first conduit 11. The first conduit 11 and the second conduit 12 simultaneously connect the infusion port 2 and the fluid storage bag 3. With the above-mentioned structure, it is possible to use a syringe to perform suction and injection actions, but because the diameter of the second conduit 12 is much smaller than that of the first conduit 11, the liquid can only flow from the second conduit 12 to the infusion port 2 under the action of an external force, so the combination with the fluid storage bag 3 can effectively prevent the liquid in the fluid storage bag 3 from flowing out of the doll body 1.

[0029] In further detail, in order to prevent children from squeezing the doll body with their hands when playing with the doll, causing the liquid in the liquid storage capsule 3 to flow out, the simulated doll is provided with a hard cavity 14 inside, and the hard cavity 14 is used to place the liquid storage capsule 3. The hard cavity 14 is preferably made of metal material.

[0030] To be more specific, the diameter of the needle of the non-damaging needle assembly 4 is at least 1 mm, which is safer.

[0031] To further elaborate, the doll body 1 is also provided with an injection marking area 15 , and the injection marking area 15 corresponds to the location of the puncture seat 5 of the infusion port 2 .

[0032] In further detail, the injection mark area 15 is provided with a mesh for puncture, and the injection mark area 15 is also made of a flexible material. The number of meshes is preferably one and is concentric with the insertion hole 9, and the diameter is slightly larger than the insertion hole 9. The color of the injection mark area 15 is different from the color of the doll body 1, and is more eye-catching.

[0033] To further elaborate, in order to prevent the syringe needle from injuring children, the non-injurious needle assembly 4 is also provided with an injection seat 16, and the injection seat 16 is used to dock the syringe. It is safer to use a syringe without a needle to dock the injection seat 16 for injection.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although the present invention uses more terms such as doll body 1, infusion port 2, fluid storage bag 3, non-destructive needle assembly 4, puncture seat 5, catheter lock 6, flexible puncture septum 7, sample box 8, plug hole 9, patch 10, first catheter 11, second catheter 12, one-way valve 13, hard cavity 14, injection mark area 15, injection seat 16, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
