Description

Technical Field

[0001] The utility model belongs to the technical field of medical education and training, and specifically relates to an intravenous injection training device. Background Art

[0002] Intravenous injection is a method of administering drugs through veins. The drugs can directly enter the blood and reach the whole body. It is the fastest way to administer drugs. Intravenous injection is a non-independent therapeutic nursing operation and an important part of nursing practice. Nursing students must master it proficiently, which requires a lot of practical training.

[0003] In venipuncture training, in very rare cases, mutual injections are used for practice. This method will cause pain and possible infection, so it cannot be practiced repeatedly. In general, a simulated arm with blood vessels is used for injection practice. The blood vessels in this type of simulated arm are relatively clear and prominent, which will make students dependent on it and make it difficult to perform intravenous injections on different patients according to their conditions, especially for some patients with unclear veins. At the same time, this type of simulated arm will leave irreversible damage after multiple punctures, and the replacement cost is high, resulting in poor training results. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4As shown, the utility model provides an intravenous injection training device, including a bottom plate 1, one end of the upper surface of the bottom plate 1 is fixedly connected to a vertical plate 2, the upper end of the vertical plate 2 is fixedly connected to a cross bar 5, the outer side of the cross bar 5 is sleeved with a sleeve 6, and the end of the cross bar 5 is provided with a spring structure for fixing the sleeve 6, the outer side of the sleeve 6 is sleeved with an outer tube 7, both ends of the sleeve 6 are connected to the outer tube 7 through a plurality of fixing plates, the outer tube 7 is sleeved with a simulated skin sleeve 14, and a plurality of through grooves 8 are penetrated and opened on the circumferential surface of the outer tube 7. Both ends of each through groove 8 are provided with a sleeve ring 9, and the sleeve ring 9 is fixedly connected to the inner wall of the outer tube 7, the same silicone hose 15 is sleeved in every two sleeve rings 9, and the sleeve ring 9 is provided with a clamping assembly 3 for fixing the silicone hose 15, and a plurality of push plates 10 abutting and adapting with the silicone hose 15 are provided on the circumferential surface of the sleeve 6, and the plurality of push plates 10 correspond one-to-one to the plurality of through grooves 8, and a plurality of groups of spring telescopic rods 4 are provided on the side wall of the sleeve 6 for respectively pushing the push plates 10 to move toward the through grooves 8.

[0026] As an optional embodiment, the spring clip structure includes a hollow groove 11 opened at the end of the cross bar 5, and four notches 12 are evenly opened on the side wall of the hollow groove 11. The four notches 12 are fixedly connected with inclined spring clips 13 that abut against the end of the sleeve 6. By pressing the four inclined spring clips 13 into the hollow groove 11, the sleeve 6 can be sleeved on the outside of the cross bar 5. At the same time, under the action of elastic force, the ends of the four inclined spring clips 13 abut and rub against the inner wall of the sleeve 6. When the sleeve 6 is completely sleeved on the cross bar 5, the ends of the four inclined spring clips 13 are inclined outside the end of the sleeve 6, and the sleeve 6 is squeezed and fixed by the elastic force. At the same time, the sleeve 6 and the outer tube 7 are prevented from flexibly rotating on the outside of the cross bar 5 through the contact friction between the two.

[0027] Specifically, one end of the outer tube 7 is set to be truncated into a cone shape, and the small diameter end is far away from the middle, which can play a guiding role when the simulated skin cover 14 is sheathed on the outside of the outer tube 7, so that the simulated skin cover 14 can be better sheathed on the outside.

[0028] Reference Figure 2 As shown, the clamping assembly 3 includes a bolt hole 3a opened on the side wall of the sleeve ring 9, and a bolt 3b is threadedly connected in the bolt hole 3a. An arc-shaped clamp plate 3c is provided inside the sleeve ring 9, and the end of the bolt 3b is rotatably connected to the outer arc surface of the arc-shaped clamp plate 3c. When the silicone hose 15 is inserted into two opposite sleeve rings 9, the bolt 3b is rotated to move in the bolt hole 3a, and at the same time, the arc-shaped clamp plate 3c is driven to move in the sleeve ring 9 to clamp and fix the side wall of the silicone hose 15. At the same time, the design of the arc-shaped clamp plate 3c can prevent the silicone hose 15 from being squeezed in an interrupted flow manner. It is worth mentioning that when the needle of the syringe penetrates into the silicone hose 15, the contents thereof are pushed and can flow out at the end of the silicone hose 15, completing the puncture verification, that is, the injection is successful. Any situation other than this is unsuccessful.

[0029] Specifically, the cross-section of the push plate 10 is arc-shaped, and both ends of the push plate 10 are arc-shaped, which can prevent the silicone hose 15 from detaching from the push plate 10. At the same time, the arc-shaped design can prevent the silicone hose 15 from being worn by the end edges of the push plate 10 after being supported and bent.

[0030] Reference Figure 3 As shown, there are two spring telescopic rods 4 in each group, and two spring telescopic rods 4 are provided at each push plate 10, the spring telescopic rod 4 includes a hollow tube 4a fixedly connected to the side wall of the sleeve 6, and a movable rod 4b is sleeved in the hollow tube 4a, and the end of the movable rod 4b is fixedly connected to the push plate 10, and a spring 4c is connected between the end of the movable rod 4b and the inner bottom of the hollow tube 4a. Two spring telescopic rods 4 are provided at each push plate 10, which can provide stable support for the push plate 10. At the same time, the elastic force of the spring 4c pushes the movable rod 4b and the push plate 10 to move toward the through groove 8, thereby adjusting the distance between the silicone hose 15 and the simulated skin cover 14, which can better simulate the actual degree of visibility of blood vessels under the skin.

[0031] Specifically, the surface of the silicone hose 15 is set to red, so that the silicone hose 15 can simulate real blood vessels under the simulated skin cover 14 to improve the training effect.

[0032] With the above structure, when in use, the simulated skin cover 14 is sleeved on the outer tube 7, and then the sleeve 6 is sleeved on the outside of the cross bar 5. At this time, the position of the sleeve 6 is fixed by the spring structure, and then multiple silicone hoses 15 are inserted into multiple relative sleeve rings 9 in turn as needed, and one end of the silicone hose 15 is fixed by the clamping assembly 3. At this time, the push plate 10 at each through groove 8 abuts against one side of the silicone hose 15, and the elastic force of the spring telescopic rod 4 pushes the silicone hose 15 to move close to the through groove 8. When it moves to a suitable distance, the other end of the silicone hose 15 is fixed, and the injection practice is achieved by using an injection needle to pierce the simulated skin cover 14 and the silicone hose 15 at the same time until the syringe needle is located inside the silicone hose 15.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
