Introduction to Infusion with Indwelling Needle

[0003] During the infusion of clinical patients, unexpected situations such as going out for examinations and using the toilet often occur. It is inconvenient to carry the infusion, so the connection between the infusion set and the indwelling needle can only be disconnected and the infusion is paused; the removed infusion (infusion bottle + infusion set) is taken back to the treatment room and placed in a sterile tray laid out. When the patient returns after the examination or using the toilet, it is taken out from the treatment room and continued to be infused to the patient (ward). However, this increases the workload of nurses, and also increases the risk of infection along the way of taking and delivering the infusion. Therefore, I have made the following improvements to the infusion set to facilitate on-site sealing, which not only reduces the risk of infection but also reduces the workload of nurses. Content of the Utility Model

[0004] The utility model provides an infusion set, which mainly solves one of the following problems: how to reduce the workload of nurses and the risk of infection after removing the infusion.

[0005] In order to achieve the above-mentioned utility model purpose, the technical solution adopted by the utility model is as follows:

[0006] An infusion set, a sealing cap, which includes an outer tube and an inner tube; one end of the outer tube and the inner tube is fixedly connected, and the outer tube and the inner tube are coaxially fixed; an external thread is provided on the outer wall of the inner tube; the threaded tube at the infusion end of the infusion set can be inserted between the outer tube and the inner tube, and the external thread of the inner tube is connected to the internal thread of the infusion end;

[0007] A hanging tree, the main connection end of which is connected to the drip chamber of the infusion set, the hanging tree branches out into multiple side branches, and a threaded cylinder is fixedly arranged at one end of the side branch far away from the main connection end, and the threaded cylinder has an internal thread;

[0008] The sealing cap is connected to the threaded cylinder.

[0009] Further, the hanging tree branches out into three side branches, a threaded cylinder is fixedly arranged at one end of each side branch far away from the main connection end, and each threaded cylinder is connected to a sealing cap.

[0010] Furthermore, a fixed head is fixedly arranged on the drip chamber; the fixed head is provided with a threaded hole which is in threaded connection with the main connection end of the hanging tree;

[0011] An expansion head is fixedly arranged on the outer wall of the sealing cap. The expansion head is provided with an expansion threaded hole which is used for being in threaded connection with the main connection end of the hanging tree.

[0012] The beneficial effects of the utility model are as follows: [[ID=…]]

[0013] When the patient goes out for an examination or goes to the toilet during the infusion, the infusion set is disconnected from the indwelling needle (i.e., the removed infusion); then, a sealing cap 30 is taken off from the drip chamber 02, and the sealing cap 30 is connected to the infusion end 01 of the infusion set, so that the sealing cap 30 can block the infusion end 01 of the infusion set 00, for example, preventing bacteria and dust from falling into the infusion end 01 of the infusion set 00; compared with the prior art, there is no need to transfer the removed infusion between the treatment room and the ward; the workload of nurses and the infection risk are reduced.

[0024] The following further describes the specific implementation manners of the present utility model in conjunction with the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0025] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0026] As Figures 1 to 5 shown, an infusion set,

[0027] The closing cap 30 includes an outer tube 31 and an inner tube 32; one ends of the outer tube 31 and the inner tube 32 are fixedly connected, and the outer tube 31 and the inner tube 32 are coaxially fixed; an external thread is provided on the outer wall of the inner tube 32; the threaded tube at the infusion end 01 of the infusion set 00 can be inserted between the outer tube 31 and the inner tube 32, and the external thread of the inner tube 32 is connected to the internal thread of the infusion end 01, that is, the closing cap 30 can block the infusion end 01 of the infusion set 00, for example, bacteria and dust fall into the infusion end 01 of the infusion set 00.

[0028] The main connection end 21 of the hanging tree 20 is connected to the drip chamber 02 of the infusion set 00. The hanging tree 20 branches out multiple side branches 22. A threaded cylinder 23 is fixedly provided at one end of the side branch 22 away from the main connection end 21, and the threaded cylinder 23 has an internal thread;

[0029] The closing cap 30 is connected to the threaded cylinder 23.

[0030] Principle: When the patient goes out for an examination or goes to the toilet during the infusion, the infusion set is disconnected from the indwelling needle (i.e., the removed infusion); then a closing cap 30 is taken off from the drip chamber 02, and the closing cap 30 is connected to the infusion end 01 of the infusion set, so that the closing cap 30 can block the infusion end 01 of the infusion set 00, for example, bacteria and dust fall into the infusion end 01 of the infusion set 00; compared with the prior art, there is no need to transfer the removed infusion between the treatment room and the ward; the workload of nurses and the infection risk are reduced.

[0031] Furthermore, the hanging tree 20 branches out three side branches 22. A threaded cylinder 23 is fixedly provided at one end of each side branch 22 away from the main connection end 21, and each threaded cylinder 23 is connected to a closing cap 30. That is, when the infusion set leaves the factory, three available closing caps 30 are preset, which can meet the needs of the general patient going out (to the toilet) three times during the infusion.

[0032] Furthermore, some patients need to use the toilet frequently due to having received diuretic injections or for other special reasons, resulting in a shortage of the three preset sealing caps 30. However, for bedridden patients, since they are unable to walk outside, they may not use even a single sealing cap 30. Therefore, the unused sealing caps 30 can be transferred to other patients. The following improvements are made for this situation.

[0033] Refer to Figure 3 , the drip chamber 02 is fixedly provided with a fixed head 10; the fixed head 10 is provided with a threaded hole, and this threaded hole is threadedly connected to the main connection end 21 of the hanging tree 20.

[0034] An extension head 33 is fixedly provided on the outer wall of the sealing cap 30, and the extension head 33 is provided with an extension threaded hole, which is used for threaded connection with the main connection end 21 of the hanging tree 20.

[0035] Transfer the hanging tree 20 (the transferred hanging tree 20) with the remaining sealing caps 30 to the patient who goes out frequently. Specifically, the main connection end 21 of the transferred hanging tree 20 is connected to the extension head 33 of the sealing cap 30 of the (patient who goes out frequently).

[0036] The above are only the preferred embodiments of the utility model patent, and are not intended to limit the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included within the protection scope of the utility model patent.
