Abstract

The placement of air in the pathway of vein infusion of serums and drugs is an event that occurs commonly and frequently. The entry of air into the patient's vein is an undesirable and potentially dangerous event. The current method of removing air is to disconnect the serum set from the Angiocath, which is a hard, non-sterile, unhygienic, and incomplete method. In our proposed method, Angiocath CV line & Shalden are equipped with air evacuation valve, and discharge of air into the serum set is done without the need to disconnect the serum set from the Angiocath, etc. through this valve. So that, by 90-degree rotation of the air evacuation valve, the flow path of the serum to the patient's vein closes and the pathway to the outside opens. After complete exit of the air from the serum set and 90-degree rotation of the bleed air evacuation valve and return to the previous state, the path of the serum closes to the outside and opens to the patient's vein.

Description

Angiocath CV line & Shalden with air evacuation valve to discharge of air from infusion vein system

In one general aspect, the present disclosure describes Angiocath CV line & Shalden with air evacuation valve to discharge of air from infusion vein system (serum set & drug infusion set) .it is in the technical field of medical engineering - health. The placement of air in the pathway of vein infusion of serums and drugs is an event that occurs commonly and frequently. Moreover, the entry of air into the patient's vein in any form and any amount is an undesirable and potentially dangerous event. Therefore, if there is air in the intravenous infusion path, it should be removed. The current and common approach of removing air is in a way that the serum set is initially removed from the Angiocath to provide the possibility of discharging air inside the serum set. The new set is sometimes replaced with the previous set that the possibility of "non-sterilizing" the serum set and Angiocath in both cases is high. As well as, when replacing or removing the serum set for bleeding, there is a risk of contamination of the environment and patient with the exit of blood from the patient's veins. This is a hard, non-sterile, unhygienic, and incomplete procedure.

In our proposed method, Angiocath CV line & Shalden are equipped with air evacuation valve, and discharge of air into the serum set is done without the need to disconnect the serum set from the Angiocath, etc. through this valve. So that, by 90-degree rotation of the air evacuation valve, the flow path of the serum to the patient's vein closes and the pathway to the outside opens. After complete exit of the air from the serum set and 90-degree rotation of the bleed air evacuation valve and return to the previous state, the path of the serum closes to the outside and opens to the patient's vein.

The innovation refers to an advantageous technology in Biomedical Engineering - Health .

The fact is that attempts have been made in the field of producing various types of Angiocath, CV line & Shalden with different purposes and with very high quality, but none of them have addressed the essential issue of bleeding from the intravenous system. Therefore, it can be claimed for the first time in the world that there is a reliable method of bleeding the patient's intravenous infusion system, in which both bleed from infusion set is fully done and there is no bleeding or contamination of the environment as well, and it's easily done by a person.

We also now face the exit of blood from the patient's body after (finding) IV/intravenous line and before connecting the serum to the Angiocath that blocking the vein is usually done by a second person. However, with these measures, after ensuring the accuracy of (finding) IV/intravenous line, the bleeding path is easily closed by 90-degree rotation of the air evacuation valve, and the work environment remains clean and healthy.

Description or the related art including information disclosed . examples of such assemblies are disclosed in the following U.S. pat. Nos.:

Patent No: 4,187,847 , Airless intravenous fluid system:

The device is used to maintain fluid pressure during the injection. Indeed, it works after the initial bleed. Except for the first time, bleeding is still required during intravenous infusion. This further illustrates the need for an invented device for continuous bleed. This device actually compresses the injection tank to provide pressure during injection as a fluid head.

Patent No: 6531 356 B1 , Gas and solid trap for an intravenous line:

The device is used to trap air and solid materials during the injection. One of the drawbacks is the placement angle. The device must be positioned horizontally to have the best performance. If the angle changes, there will also be the possibility of cutoff. This bulky and cumbersome device is hard to work with, but our Angiocath is compact and easy to work with, and multiple dilemmas can be simultaneously remedied with it.

Patent No: 9,814,866 B1 , Flushable Drainage device and method of use:

The device refers to a drainage valve used to block the injection pipes and ducts passing fluid and not to be used as a deaerator. It should be added to other medical devices. It is bulky and has a complex system. But our device is an Angiocath with the capability of bleeding from the intravenous system, and it is a simple, highly functional with convenient use device.

Patent No: 2010/0204648 A1 , System and methods for providing a flushable catheter:

The device is used to prevent the return of blood and bleeding during the injection process. In the injection process during the connection of different components to the stent after piercing the vein, there is the possibility of bleeding. With the help of this device, we can prevent the bleeding at this stage. This has a fundamental difference with bleed, and bleed is not its capability. In addition to the ability to provide comfortable and complete bleed, our Angiocath can also be used to stop bleeding.

Patent No: 5,295,969 , Vascular access device with air-tight blood containment capability:

The device is used to insert a stent into the vein and involves modifying the stent structure. It prevents the return of blood and bleeding by trapping the returned blood inside an air chamber and is not used for bleed.

Patent No: 5,984,895, Vascular blood flashback containment device with improved sealing capability:

The device is used to insert a stent into the vein and prevent the return of blood and bleeding. It also shows the initial blood flow. While our intended device is an Angiocath that is used for bleeding. But the device should be added that it is difficult to use and cannot bleed.

Patent No: 2008/0108973 A1 , Vascular access device gas displacement:

In terms of the title of the invention, the device is similar to our considered device and has been proposed for bleed. But there is a fundamental difference with our intended device. The device comprises a gas chamber and a container inside a vascular access device, in which gas is displaced between the gas chamber and the container inside the device.

1- In terms of its components and method, the device is completely different from our claimed device.

2- The use of this device is complex and cumbersome and should be added to the intravenous access device.

But the opposite:

1- Our inventive device is an Angiocath that the ability to exit the air is provided through it.

2- There is no need to add another device, and the air evacuation valve is part of the structure of the Angiocath.

3- It is easy to use and can be performed by a person.

Patent No: 2005/0247203 , Gas separation device:

The device is used to separate air and blood in different processes. The angle of its placement is of great importance, and it must be placed vertically. It is used in cases where the air and the blood flow simultaneously along the path. The basic difference compared with our intended system is its complexity as well as its need for being vertical. This is while our desired invention can have a good performance at any positioning angle, along with its simplicity.

This summary is intended to provide an overview of the subject matter of the present disclosure, and is not intended to identify essential elements or key elements of the subject matter, nor is it intended to be used to determine the scope of the claimed implementations. The proper scope of the present disclosure may be ascertained from the claims set forth below in view of the detailed description below and the drawings.

One of the problems of the medical staff on the bedside of patients occurring during the connection of serum or replacement of the finished serum of patients is the issue of bleeding from the patient's intravenous infusion system and the prevention of air entry into the patient's cardiovascular system.

As we know, air entry into the cardiovascular system is considered to be a fatal tragedy. Especially in some heart valve diseases, the entry of a small amount of air into the heart can be accompanied with dire consequences.

In the conventional method, after connecting the serum set to serum bottles or vials of drugs, bleeding from the serum set is performed. This is done when the patient's vein is taken, and at the same time, another problem is preventing the outflow of blood from Angiocath. In this situation, although the second person vigorously attempts to block the vein containing the Angiocath, due to problems such as lack of easy access to the vein and failure to properly find the path of vein by a second person, therefore, the vein is not entirely closed, and we face bleeding and contamination of the environment and blood of patients. This story always continues after replacing the patient's serum set or starting a new infusion.

In our invention, through adding an air evacuation valve just before the entry of serum to the body, without having to disconnect the serum from Angiocath CV line & Shalden, the path blocks to the patient's body and the path opens to the outside of the patient's body only with a 90-degree rotation. In addition to ease of work, complete and accurate and stress-free bleeding occurs. Nurses completely and simply do the bleeding of the patient's venous system with minimal stress and without any bloodshed or contamination of the environment only by a person.

Before direct injection valve of the drug, an air evacuation valve should be embedded that, if necessary such as in the presence of air on the path of infusion of the serum or drugs, with 90-degree rotation of the air evacuation valve, the path of the serum set closes to the patient and the path opens to the outside of the body.

With the flow of serum, the air inside it completely exit. After ensuring complete exit of air, by 90-degree rotation of the air evacuation valve, the path of serum and drugs to the patient re-opens and is closed to the outside.

This air evacuation valve at the time of (finding) IV/intravenous line, after correct placement of Angiocath within the vein with a 90 ° rotation, can prevent the exit of blood through the Angiocath and prevent the contamination of the environment, and the Angiocath installer gently fixes and connects the serum sets and drugs without the stress of bleeding from the Angiocath.

Similarly, this air evacuation valve can also be embedded in the case of Shalden and the central vein, through which bleeding is performed.

1- Bleeding from the intravenous infusion system, including serum set, can be done easily and quickly.

2- Bleeding can be fully conducted by one of the personnel.

3- There is no need to disconnect serum set from Angiocath for bleeding of the intravenous infusion system.

4- It prevents the contamination of the environment around the patient (bed-linen and clothes) by blood.

5- It reduces the risk of transmission of infection from the environment to the body of the patient through the intravenous infusion system.

6- It reduces the risk of contamination of health-medical personnel by the patient's blood.

7- Immediately after embedding the Angiocath into the patient's vein, by rotating the air evacuation valve, it prevents the outflow of blood to the outside of the patient's body.

8- It reduces the patient's stress caused by seeing his/her blood

9- Complete and rapid discharge of blood back into the serum set without the need to disconnect the serum set from the Angiocath.

Examples

This Angiocath has several advantages over the currently used Angiocaths. For example:

1- After insertion of the Angiocath catheter into the vein in the common method, the path of the vessel should be closed by the compression of it, in which the obstruction is not often complete, and some blood leaks out. The Angiocath opening also closes with a special lid (cap). With 90-degree rotation of air evacuation valve, the blood flow path is completely closed by our proposed Angiocath, and there is no need to press the vein path and no need to cover.

2- If air is in the serum set, which commonly and frequently occurs, the serum set must be removed from the Angiocath, and the serum must be emptied elsewhere so that it reaches the air inside the serum set and air be removed. Or if the serum set is changed, however, the path of the vessel should often be compressed during this time to prevent the outflow of blood. The process of the possibility of environmental contamination with the blood of the patient, as well as the risk of transmission of infection to the patient is very high. However, in use of our Angiocath without having to disconnect the serum set from the Angiocath without the need to press the patient's vessel, only by 90-degree rotation of air evacuation valve, the vein path closes and the outward path open, the risk of contaminating the environment with the patient's blood and the risk of transmitting the infection to the patient is greatly reduced.

3- When the Angiocath is not used for a short time, the blood clot is formed at the junction of the serum set to the Angiocath and makes it difficult to use. To fix this problem, the serum set must be often separated from the Angiocath to remove the blood clot.

Using our Angiocath without having to disconnect the serum set from the Angiocath, with the vessel outflow obstruction by rotating the air evacuation valve and opening the path of movement of the serum outward, we remove the blood clot from the end of the serum set.

4- The device can also be used in CV line & Shalden.

Industries related to biomedical engineering are among the most widely used industries. As well as, according to the daily consumption of millions of Angiocaths and serum sets, and the need for all of them to bleed, therefore, they have incredibly high applications in these industries. Moreover, providing a more secure device for patients and health care workers and more convenient to use have led to its wide acceptance and mass production and creation of more employment.

Claims

Angiocath with at least one air evacuation valve to discharge of air and waste (clot) in the intravenous infusion system and prevents the return of blood from returning to the bloodstream after (finding) IV/intravenous line. (Serum set & drug infusion set) comprising :
At least one inlet of Angiocath ;
An outlet of the Angiocath into the patient's vein ;
At least one air evacuation valve for bleed air ;
An outlet of the Angiocath outside the patient's body to remove the air in the serum set ; and
An Angiocath needle for perforating the patient's skin and vein .
According to claim No. 1, the Angiocath stated could be the CV line or Shalden.
According to claim No. 1, the air evacuation valve stated has an air evacuation valve for bleeding.
According to claims Nos. 1 and 2, there is at least one inlet of Angiocath stated, at least 2 inlets in Shalden, and at least 2 inlets in CV line.
According to claim No. 1, the air evacuation valve stated has at least one outlet to the outside of the Angiocath.
According to claim No. 1, the Angiocath stated provides the possibility of discharging air and waste from the intravenous infusion system without having to disconnect the serum set from the Angiocath.
According to claim No. 1, by 90-degree rotation of the air evacuation valve, after (finding) IV/intravenous line while removing the needle, outflow of blood from the veins is prevented, and Angiocath is fixed on the patient's skin without any stress.
The method of discharging air and waste products, including blood clots, consists of:
90-degree rotation of the air evacuation valve closes the vein pathway and opens the pathway to the outside of the Angiocath and the patient's vein through the discharge valve when air and waste products including blood clots place into the serum set.
Blocking the pathway of fluid movement within the serum set toward the patient's vein and opening the pathway of movement of the serum to the outside
The flow of finding serum-containing air and waste products, including the blood clot out of the Angiocath and the patient's body.
According to claim No. 8, by 90-degree rotation of the stated air evacuation valve, In the case of CV line & Shalden, we also prevent shedding of blood outside the vein after removal of the guidewire, and we fix it to CV line & Shalden in stress-free conditions.
