Description

Compression hemostat for packing

technical field

The utility model relates to a medical instrument, in particular to a surgical hemostatic instrument, in particular to a pressurized hemostatic device for packing used in conjunction with gauze packing for hemostasis. the

Background technique

At present, gauze packing is one of the effective means of hemostasis in the field of surgery. At present, gauze packing is widely used in gynecology, general surgery, thoracic surgery, etc., but there are still many clinical problems after packing: 1. Intraoperative bleeding after packing , due to the displacement or loosening of the abdominal packing gauze after the abdomen was closed or the patient was moved, which may cause postoperative bleeding again; 2. The patient's bleeding was controlled after the intraoperative packing, but the patient's own blood coagulation function was poor, and the blood coagulation function was not corrected in time. Wound bleeding occurs after repacking; 3. After the operation or turning over of the patient, the compression position of the packing gauze changes, and bleeding may occur again; 4. The specific situation of the packing gauze is analyzed in detail, and the gauze is removed in time. If it is taken out too early, bleeding occurs again , Taking the gauze too late may cause infection, which increases the possibility of a second blow, and the prognosis of the patient is poor. Therefore, it is imperative to design a device with the following functions that is matched with gauze packing and hemostasis: 1. Effectively control bleeding; 2. Real-time monitoring of pressure, and adjust and compress the hemostatic pressure according to the pressure required by the patient's bleeding site, so as to control rebleeding and avoid reoperation Risk; 3. After filling, the position is fixed and difficult to move, resulting in the risk of invalid filling. It can effectively control bleeding for clinicians and bring good news to patients. the

A drainage tube 3, one end of the drainage tube 3 is located or mounted on the outer side of the airbag 1 away from the panel 2;

An inflation tube 4, one end of the inflation tube is connected to the air bag 1 and communicates with its inner cavity, and the other end is provided with an inflation port 6 connected to the inflation device;

A pressure measuring device 5, the pressure measuring device 5 is installed on the inflatable pipe 4, the pressure measuring device 5 can be a pressure gauge, can also be a pressure sensor, the pressure measuring device 5 can be a one-way pressure measuring structure, and can also be equipped with a pressure measuring device. Air valve to adjust the pressure in the air bag.

The panel 2 is a board with moderate elasticity and hardness, so that it can not only prevent bending and deformation due to the action of the airbag skin, but also prevent its hardness from being too large to cause damage to human tissue. the

Said inflation pipe 4 is also connected with a pressure relief device, which can be installed independently or jointly with the pressure measuring device 5 . Separately designed to use a deflation knob similar to a blood pressure monitor. the

A one-way valve is installed in the inflation port 6 . the

The beneficial effects of the utility model:

1. It can control bleeding quickly, conveniently and effectively, and reduce the risk of reoperation and death of patients.

2. It can observe whether there is rebleeding in real time and accurately, and provide a basis for taking out the gauze. the

3. The pressure can be adjusted according to the hemostatic pressure required by the bleeding site to control the bleeding without repacking. the

4. The appearance of the device is simple and beautiful, and the operability is strong. the

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. the

As shown in Figure 1-3. the

A pressurized hemostat for tamponade, which includes an air bag 1, a panel 2, a drainage tube 3, an inflatable tube 4 and a pressure measuring device 5, and a pressure relief device should be provided if necessary, as shown in Figure 1, the air bag 1 is used for Generate an adjustable force to compress the bleeding surface; when there is bleeding in the drainage tube 3, the gauze can be pressed tightly on the wound surface by opening the air bag or increasing the pressure in the air bag, and the panel 2 is installed in the aforementioned air bag 1 And it can limit the expansion of the airbag 1 to one side. The panel 2 should be made of various plate-shaped structures with moderate elasticity and hardness, such as circular, square, triangular, polygonal, etc., and the specifications should be serialized so that according to the size of the wound surface When choosing a suitable hemostat, panel 2 should not only prevent the suture surface or surface tissue from being bent and deformed by the action of the airbag skin, but also prevent its hardness from being too large to cause damage to human tissue (suture surface or surface). The drainage tube 3 is mainly used to observe the hemostatic effect. If there is no bleeding, the hemostatic airbag of the present utility model may not act, so one end of it is preferably positioned at or mounted on the side of the airbag 1 outside away from the panel 2 to contact with the gauze; One end of the tube 4 is connected to the air bag 1 and communicates with its inner cavity, and the other end is provided with an inflation port 6 connected to the inflatable device. The inflation port 6 is preferably provided with a one-way valve. A corresponding unloading device must be provided to relieve the pressure when the pressure at the wound site is too large, so as to prevent the blood circulation from being affected by the excessive pressure; the pressure measuring device 5 is installed on the inflatable tube 4, and the pressure measuring device 5 can be a pressure gauge. It can also be a pressure sensor, and the pressure measuring device 5 can be a one-way pressure measuring structure, and can also be provided with an air release valve so as to adjust the pressure in the air bag. the

The pressurized hemostatic device for packing of the utility model is mainly composed of an airbag, a panel, a pressure measuring device, an inflation port, a drainage tube, etc. On the surface, the material of the airbag is natural latex; the surface of the board is made of plastic tissue engineering material, which does not change with the filling position and temperature of the human body, has a certain hardness, and the surface maintains a certain contraction tension, but does not damage the surrounding tissue; The pressure sensor can be installed in the airbag, and the pressure sensor is displayed on the display device outside the airbag through the wire; the inflation of the airbag needs to be inflated through the inflation port, and a one-way valve is installed; the catheter drainage port is connected to the drainage bag observation window, whether hemostasis, bleeding Whether to stop and when to stop provide the basis. the
