CN109044708B - A kind of auxiliary stent for deep vein catheter occlusion thrombolysis - Google Patents

Abstract

An auxiliary bracket for deep venous catheter occlusion thrombolysis. The invention belongs to the field of medical auxiliary equipment application, and particularly discloses a support frame design method suitable for foot joint venous thrombolysis. The stress response of the foot joint bending is spontaneously generated from time to time by the patient due to the pain of the joint during the thrombolysis process. This reaction may cause some hindrance to the foot joint thrombolysis process and may even cause the thrombolysis tube to puncture the venous vessels of the foot. The method provides a foot supporting platform for a patient with foot joint venous thrombolysis in the thrombolysis process, can inhibit the stress reaction of the patient and improve the comfort of the patient in the thrombolysis process. Greatly reduces the pain and discomfort of the patient in the thrombolysis process and reduces the workload of medical staff in the thrombolysis operation process.

Description

A kind of auxiliary stent for deep vein catheter occlusion thrombolysis

technical field

The present invention relates to the field of auxiliary equipment for interventional medical devices, and more particularly to a stent device used for assisting the intravascular treatment of venous thrombolysis in a human body.

Background technique

Popliteal-iliofemoral deep venous thrombosis is a disease caused by blood clotting in deep veins to form a thrombus, which is caused by limb necrosis and the risk of pulmonary embolism, which must pass through the Interventional treatment of deep vein thrombosis such as iliofemoral, this method is mainly through catheter thrombectomy, catheter contact thrombolysis and so on.

During the process of thrombolysis, the patient's leg is extremely painful, and it is difficult to immobilize and place the leg normally. And it will be accompanied by leg twitching, leg joint curling and other movements, which will greatly hinder the process of catheter thrombolysis. Therefore, in order to facilitate the thrombolysis process and reduce the pain of patients and the work intensity of medical staff, this medical auxiliary device for supporting the legs during catheter thrombolysis was developed.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a leg placement stent in the process of intravenous thrombolysis of the intravascular catheter of the large joint of the leg, which is used to reduce the stress reflex of the patient during the thrombolysis process and cause the thrombolysis operation. Impact. As well as solving the problem of placement and fixation of the patient's legs during the operation, and improving the comfort of the patient during the operation.

In order to solve the above problems, the technical solution adopted is: an auxiliary stent for deep vein catheter occlusion and thrombolysis. The stent includes a thigh support frame, a foot joint support and a calf support frame, and the three parts are all in the shape of a semi-circle. Designed and connected as a whole, there are a pair of strap holes at the end of the arc to fix the thigh on the bracket.

Further, the thigh support frame and the calf support frame are respectively provided with 9 ventilation holes for perspiration and ventilation of the legs, so as to prevent the growth of microorganisms caused by the lack of air circulation in the legs during the long-term thrombolysis operation.

Further, the lower end of the large foot joint bracket is provided with a slot for arranging the thrombolysis tee on the large foot joint bracket. And three-way conduit and blood conduit arrangement groove, the diameter of the groove is 10mm;

Further, the lower end of the foot joint bracket is also provided with a thrombolysis operation window, and its function is to detect the intraoperative situation of the tee tube and the intravenous injection port at any time, so that the medical staff can monitor the thrombolysis operation at any time. control.

Further, a lower bottom transparent cover plate is also provided below the large joint bracket, which is used to cover the thrombolysis operation window, and prevent the entry of external dust and debris, which may contaminate the tee pipe and related infusion pipes.

The beneficial effects of the present invention are:

1 The fixation of the drug delivery catheter connected to the three-way tube and the blood output tube during the thrombolysis process. Since the present invention designs the placement grooves of the relevant catheters, these pipelines can be arranged in an orderly manner during the operation, and the phenomenon that the pipelines are intertwined and knotted can be avoided.

2 In addition, in thrombolysis, the operation process is relatively long, and the patient is more painful during the operation. The stent is beneficial to relieve the discomfort of the patient's legs and reduce the unsafe factors caused by the curling of the legs during the operation.

3. The stent helps to reduce the workload of medical workers in the intravenous thrombolysis of the large joints of the legs. The catheter can be inserted and the drug can be injected directly through the operation window under the large joint stent, which reduces the patient's leg joints during the operation. Difficulty in thrombolysis due to excessive exercise.

Detailed ways

The present invention is described in detail below in conjunction with the accompanying drawings:

A kind of auxiliary support of deep vein catheter occlusion thrombolysis comprises: calf support frame 1, the ventilation hole 2 on the calf support frame, the thigh support frame 3, the ventilation hole 4 on the thigh support frame, the foot joint support 5, the foot joint The thrombolysis tee tube above the stent is arranged with a slot 6, the tee tube catheter and the blood catheter are arranged in a groove 7, a thrombolysis operation window 8, a lower bottom transparent cover 9, and a strap hole 10;

As shown in Figures 2 and 3, the left side is the lower leg support frame 1, the right side is the thigh support frame 3, and the middle is the foot joint support frame 5, which are respectively used in catheter thrombolysis to fix the thigh joint of the patient. Two strap holes 10 are respectively provided above them, which are used to wear straps, and the purpose is to fix the thigh and the bracket and prevent them from falling off.

The large foot joint bracket 5 is provided with a thrombolysis tee tube arrangement slot 6 on the foot joint bracket, which is used for placing the thrombolysis tee tube in catheter thrombolysis, and the three interfaces connected with the tee tube, They are the inlet of the surgical drug delivery catheter, the outlet of the thrombus catheter and the venous communication tube. At the same time, four blood conduit arrangement grooves 7 are distributed around the three-way tube for placing the conduits connected to the three-way tube, so as to avoid staggered knots between the conduits.

As shown in FIG. 3 , a lower bottom transparent cover 9 is arranged at the bottom of the foot joint bracket 5 , which has two functions: 1. It is used to push and pull the operating port during thrombolysis to prevent the entry of debris. 2. It is convenient for medical staff to observe the flow of drugs and blood in the thrombolysis pipeline when the cover is closed.

The above is only the preferred implementation method of the present invention, rather than limiting the patent scope of the present invention. If the equivalent process design transformation made by the description of the present invention and its accompanying drawings is used, or the present invention is directly or indirectly applied In other related technical fields, all are included within the scope of patent protection of the present invention.
