Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a drug delivery device for delivery into the patient's abdominal cavity. Background Art

[0002] Non-compressible truncal hemorrhage is the leading cause of potentially preventable deaths in the pre-hospital and battlefield settings. As the largest solid organ in the human body, the liver is an important component of non-compressible truncal hemorrhage due to trauma. Faced with this problem, how to quickly stop bleeding is the key to saving lives. Polysaccharide-based hemostatic materials such as cellulose and starch have shown great potential in the treatment of non-compressible liver hemorrhage due to their good biocompatibility, biodegradability and unique hemostatic properties.

[0003] Adam et al. analyzed the casualties of US troops registered by the US Department of Defense Trauma Registry between 2002 and 2010 and found that solid organ (liver, spleen, kidney) bleeding accounted for 29.3% of NCTH. In abdominal trauma, the liver and spleen were the main organs injured. Kisat et al. analyzed the US National Civilian Trauma Database from 2007 to 2009 and found that solid organ injury accounted for 27% of NCTH casualties.

[0004] However, since the liver bleeding site is located deep in the abdominal cavity, the time for first aid to stop bleeding is very urgent in a battlefield environment or outdoor first aid environment. Although it is convenient to stop bleeding for trauma, the lack of abundant hemostatic tools makes it impossible to quickly stop bleeding for intra-abdominal wounds. Even with polysaccharide-based hemostatic materials such as cellulose and starch, how to deliver hemostatic microspheres of the corresponding materials into the bleeding site during pre-hospital intervention is a major problem.

[0037] Embodiment 1

[0038] See also Figure 1 and Figure 4 The present invention provides a device for delivering medication into the patient's abdominal cavity, comprising a balloon 1, and further comprising: a connecting seat 2 is arranged at the top of the balloon 1, and a telescopic tube 3 is detachably connected to the connecting seat 2; a medicine box 6 is also arranged inside the balloon 1, and the medicine box 6 has an air port for allowing the gas inside the balloon 1 to enter the inside of the medicine box 6, and the air port, the inner cavity of the medicine box 6 and the telescopic tube 3 are sequentially connected along the airflow direction.

[0039] The medicine box 6 is installed on the connecting seat 2. The medicine box 6 is inside the balloon 1. Hemostatic microspheres are placed in the medicine box 6. The materials used in the device can meet the biological safety required by medical devices while meeting the functional requirements. The balloon 1 can apply air pressure to the medicine box 6 by pressing, so that the hemostatic microspheres in the medicine box 6 are sprayed into the telescopic tube 3. The hemostatic microspheres are sprayed on the patient's wound after passing through the telescopic rod to stop bleeding accurately.

[0040] The working principle of this embodiment is as follows: when in use, the telescopic tube 3 is first snap-fitted and installed with the connecting seat 2, the medicine box 6 is installed inside the balloon 1 when it leaves the factory, the telescopic tube 3 itself is interference-connected, and can stop at any position when telescoped, and the telescopic tube 3 is up to 20 cm long. At this time, the top end of the telescopic tube 3 is sent into the bleeding site of the liver in the abdominal cavity through the external wound, and the hemostatic microspheres in the balloon 1 are sent to the bleeding site by quickly pressing the rear side, so as to achieve the purpose of rapid hemostasis.
