A training device for venipuncture that can simulate skin laxity

Abstract

This utility model discloses a vein puncture training device that can simulate skin laxity, belonging to the field of medical auxiliary device technology. The simulated vein tube is fixedly connected to the limiting component by a double-sided vein tube adhesive attachment. The double-sided vein tube adhesive attachment is distributed in the middle and on the outside of the two sets of simulated vein tubes. The simulated vein tube is wrapped with a simulated skin and adipose tissue layer for puncture training. The simulated skin and adipose tissue layer are fixedly connected to the limiting component by a double-sided positioning adhesive attachment. The double-sided vein tube adhesive attachment and the double-sided positioning adhesive attachment are double-sided adhesive structures, which realizes the ability to quickly replace simulated skin and adipose tissue layers of different thicknesses. At the same time, they are all detachable structures. If a part is damaged, the part can be replaced locally without replacing the whole. Moreover, the adhesive attachment, simulated skin and adipose tissue layer and simulated vein tube are separate. Repeated folding or pulling avoids cutting, thereby improving the service life of simulated vein tube and simulated skin and adipose tissue layer.

Description

Technical Field

[0001] This utility model relates to a puncture training device, and more particularly to a venous puncture training device that can simulate skin relaxation, belonging to the field of medical auxiliary device technology. Background Technology

[0002] For example, application number 202010437331.7 is the closest prior art. In the prior art, a highly realistic arm model and simulated veins set in the highly realistic arm model are used. A notch is set at the puncture position of the highly realistic arm model, and a puncture module is filled in the notch to form a highly realistic arm model with a complete appearance. The puncture module includes simulated skin and simulated subcutaneous soft tissue. An adjustable-size vein groove is set on the simulated subcutaneous soft tissue. The simulated veins of the puncture module are embedded in the vein grooves. The simulated veins are composed of five parallel tubes.

[0003] Existing technologies are suitable for adjusting the size of veins, but because people vary in size and the thickness of subcutaneous fat and skin are also different, the depth and force of needle insertion will also be different depending on the thickness. The existing technologies mentioned above have not improved in this regard, resulting in low training accuracy, and the skin and fat simulated tissues are not easy to replace for training operations.

[0004] Therefore, there is a need for a venipuncture training device that can simulate skin laxity to improve upon the above-mentioned shortcomings. Utility Model Content

[0005] The main purpose of this invention is to provide a training device for venipuncture that can simulate skin laxity.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A training device for venipuncture that can simulate skin laxity includes a base for placing a simulated arm, wherein a limiting component and a simulated vein tube are distributed on the base;

[0008] The simulated vein tube is fixedly connected to the limiting component by a double-sided vein tube adhesive attachment. The two sets of simulated vein tubes have double-sided vein tube adhesive attachments distributed in the middle and on the outside. The simulated vein tube is wrapped with a simulated skin and adipose tissue layer for puncture training. The simulated skin and adipose tissue layer are fixedly connected to the limiting component by a double-sided positioning adhesive attachment. The double-sided vein tube adhesive attachment and the double-sided positioning adhesive attachment are double-sided adhesive structures.

[0009] Preferably, the thickness of the simulated skin and the adipose tissue layer is 3 to 100 mm, the diameter of the simulated vein is 0.1 to 0.5 mm, and a puncture detection core is inserted into the simulated vein.

[0010] Preferred, the restraint components include a restraint strap placement groove, an external adhesive layer, and a simulated arm;

[0011] The base has a placement groove, and binding straps are symmetrically installed on both sides of the base. A simulated arm is placed in the placement groove. The simulated arm has double-sided positioning adhesive and double-sided vein tube adhesive. A simulated vein tube is attached to the double-sided vein tube adhesive, and a simulated skin and adipose tissue layer is attached to the double-sided positioning adhesive.

[0012] Preferably, an outer adhesive layer and an inner adhesive layer are installed on both sides of the restraint strap, and the two sets of symmetrical outer adhesive layers are mutually covering adhesive structures.

[0013] Preferably, the base is a parallel structure, a recessed structure, or an inclined structure.

[0014] Preferably, the outer adhesive layer is wrapped around the outside of the simulated arm.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This invention provides a training device for venipuncture that can simulate skin laxity.

[0017] 1) It achieves quick replacement of simulated skin and adipose tissue layers of different thicknesses, and all of them are detachable structures. If a part is damaged, the part can be replaced locally without replacing the whole. In addition, the adhesive attachments, simulated skin and adipose tissue layers and simulated veins are separate. Repeated folding or pulling can avoid damage, thus improving the service life of simulated veins and simulated skin and adipose tissue layers.

[0018] 2) The base is symmetrically equipped with double-sided vein tube adhesive attachments. Double-sided positioning adhesive attachments are installed in the middle and on the outside of the double-sided vein tube adhesive attachments respectively. Simulated vein tubes are adhered to the double-sided vein tube adhesive attachments. Simulated skin and adipose tissue layers are covered on the double-sided positioning adhesive attachments and the double-sided vein tube adhesive attachments. The structure is simpler and the cost is reduced on the basis of a more streamlined structure.

[0019] 3) The base is an inclined structure, and double-sided venous tube adhesives are symmetrically installed on the base. Double-sided positioning adhesives are installed in the middle and on the outside of the double-sided venous tube adhesives respectively. The double-sided venous tube adhesives are covered with simulated skin and adipose tissue layers, so that the training operation end is inclined on the basis of the above improvements, which facilitates operation.

[0029] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] Example 1

[0031] like Figure 1 - Figure 4 As shown, this embodiment provides a vein puncture training device that can simulate skin relaxation, including a base 1 for placing the training device, and simulated vein tubes 3 and simulated vein tubes 3 distributed on the base 1;

[0032] The simulated vein tube 3 is fixedly connected to the simulated arm 2 via a double-sided vein tube adhesive attachment 302. The double-sided vein tube adhesive attachment 302 is distributed in the middle and on the outside of the two sets of simulated vein tubes 3. The simulated vein tube 3 is wrapped with a simulated skin and adipose tissue layer 201 for puncture training. The simulated skin and adipose tissue layer 201 is fixedly connected to the base 1 by a double-sided positioning adhesive attachment 202. The double-sided vein tube adhesive attachment 302 and the double-sided positioning adhesive attachment 202 are double-sided adhesive structures.

[0033] The base 1 has a placement groove 102. On both sides of the placement groove 102, an external adhesive layer 103 is symmetrically installed on the base 1. A simulated arm 2 is placed in the placement groove 102. The simulated arm 2 is covered with a double-sided positioning adhesive 202 and a double-sided vein tube adhesive 302. A simulated vein tube 3 is attached to the double-sided vein tube adhesive 302. A simulated skin and adipose tissue layer 201 is attached to the double-sided positioning adhesive 202.

[0034] The two sides of the restraint strap 101 are respectively equipped with an outer adhesive layer 103 and an inner adhesive layer 104, and the two sets of symmetrical outer adhesive layers 103 are mutually covering and adhesive structures.

[0035] After the double-sided vein tube adhesive attachment 302 is attached to the simulated arm 2, the simulated vein tube 3 is attached to the double-sided vein tube adhesive attachment 302. After the simulated vein tube 3 is attached, the double-sided positioning adhesive attachment 202 is attached to the middle and outer sides of the two sets of simulated vein tubes 3 respectively. After the double-sided positioning adhesive attachment 202 is fixed, simulated skin and adipose tissue layers 201 of different thicknesses (3-100 mm) are selected and covered on the simulated vein tube 3 and fixed by the double-sided positioning adhesive attachment 202. After the simulated vein tube 3 and simulated skin and adipose tissue layers 201 are installed, the simulated arm 2 is placed in the placement groove 102 and fixed by external adhesive. The alternating adhesion of the auxiliary layer 103 provides fixation. The simulated vein tube 3 and the simulated skin and adipose tissue layer 201 are fixedly connected to the base 1 by double-sided positioning adhesive 202 and double-sided vein tube adhesive 302. This allows for quick replacement of simulated skin and adipose tissue layers 201 of different thicknesses, while all are detachable structures. Damaged parts can be replaced locally without replacing the entire structure. Furthermore, the adhesive, simulated skin and adipose tissue layer 201, and simulated vein tube 3 are separate components, preventing damage from repeated folding or pulling, thus improving the service life of the simulated vein tube 3 and simulated skin and adipose tissue layer 201.

A double-sided positioning adhesive attachment 202 is installed in the middle and on the outer side of the double-sided venous tube adhesive attachment 302. A simulated venous tube 3 is adhered to the double-sided venous tube adhesive attachment 302. The double-sided positioning adhesive attachment 202 and the double-sided venous tube adhesive attachment 302 are covered with a simulated skin and adipose tissue layer 201. The structure is simpler and the cost is reduced based on the more streamlined structure.

[0038] Example 3

The base 1 has an inclined structure, and double-sided venous tube adhesive attachments 302 are symmetrically installed on the base 1. Double-sided positioning adhesive attachments 202 are installed in the middle and on the outer side of the double-sided venous tube adhesive attachments 302, respectively. 3 are adhered to the double-sided venous tube adhesive attachments 302. The double-sided positioning adhesive attachments 202 and the double-sided venous tube adhesive attachments 302 are covered with a simulated skin and adipose tissue layer 201, realizing the function of tilting the training operation end for easy operation based on the above improvements.
