Technical Field

The invention relates to an abdominal cavity drainage tube.

Background

The medical apparatus refers to instruments, equipment, appliances, in-vitro diagnostic reagents, calibrators, materials and other similar or related articles which are directly or indirectly used for a human body, and comprises required computer software, drainage tubes are one of the instruments, the types of surgical drainage tubes used clinically are various, some surgical drainage tubes are used for catheterization, some surgical drainage tubes are used for wounds, the thoracic cavity, the cerebral cavity, the gastrointestinal tract, the biliary tract and the like, the surgical drainage is used for guiding pus, blood and liquid accumulated in tissues or body cavities of the human body to the outside of the body, and preventing postoperative infection and influencing wound healing, but the existing abdominal cavity drainage tubes are fixed in a needle suture mode, so that pain of a patient is increased, and postoperative recovery rate of the patient is influenced.

Disclosure of Invention

The invention aims to provide an abdominal cavity drainage tube, which is used for solving the problems that the abdominal cavity drainage tube is fixed in a needle and thread sewing mode, so that the pain of a patient is increased, and the postoperative recovery rate of the patient is influenced.

In order to solve the technical problems, the technical scheme of the invention is as follows:

an abdominal cavity drainage tube comprises a head tube, a middle tube and a tail tube which are connected in sequence;

the head pipe is flexible and consists of a thicker front section and a thinner rear section, the front section is connected with the rear section through a transition section, a plurality of folded plates are arranged outside the rear section, and the folded plates are uniformly distributed around the axis of the head pipe;

the folded plate comprises two hard plastic strips, the two plastic strips are connected through a first flexible strip, and one end of each plastic strip, which is far away from the first flexible strip, is connected with a second flexible strip;

the middle pipe is a hard plastic pipe communicated with one end of the rear section of the head pipe, an insertion pipe and a flexible retaining ring are sleeved outside the middle pipe, a plastic nut is installed at one end of the middle pipe, exposed out of the insertion pipe, and second flexible strips at two ends of each folded plate are fixedly connected with the transition section of the head pipe and one end of the insertion pipe respectively; the retaining ring is fixedly connected with one end, far away from the second flexible strip, of the insertion pipe.

The head pipe is made by silica gel, and anterior segment one end in the head end has a hemisphere sealed head, begins to have a plurality of drainage holes on the anterior segment.

The check ring is made of silica gel, and an adhesive tape is adhered to the check ring.

The invention has the beneficial effects that: after the head tube is inserted into the incision of the abdominal wall, the nuts are used for pulling the plastic sheets to bend so as to form a baffle in the abdominal cavity, and the baffle is matched with the outer side retainer ring and clamped on two sides of the abdominal wall, so that the drainage tube is fixed, the existing fixing mode of sewing the abdominal drainage tube by using needles and threads is replaced, the pain of a patient is reduced, and the postoperative recovery rate of the patient is not influenced; on the other hand, the hemispherical sealing head on the head tube can be inserted into the abdominal cavity by a method, the skin cannot be scratched, and the drainage tube can be effectively prevented from being blocked by the drainage holes; on the other hand, the adhesive tape can be further fixed the retaining ring, improves the location effect of drainage tube.

Drawings

The invention is further described below with reference to the accompanying drawings:

FIG. 1 is a schematic front view of the present invention,

FIG. 2 is a schematic cross-sectional view of the present invention,

fig. 3 is a schematic cross-sectional view of the present invention in use.

In the figure: the head tube 1, the middle tube 2, the tail tube 3, the folded plate 4, the retainer ring 5, the adhesive tape 6, the cannula 7, the nut 8, the abdominal wall 9, the front section 11, the rear section 12, the transition section 13, the drainage hole 14, the plastic strip 41, the first flexible strip 42 and the second flexible strip 43.

Detailed Description

As shown in fig. 1 to 3, an abdominal cavity drainage tube includes a head tube 1, a middle tube 2 and a tail tube 3 which are connected in sequence;

the head pipe 1 is flexible, the head pipe 1 is composed of a thicker front section 11 and a thinner rear section 12, the front section 11 is connected with the rear section 12 through a transition section 13, a plurality of folded plates 4 are arranged outside the rear section 12, and the folded plates 4 are uniformly distributed around the axis of the head pipe 1;

the folded plate 4 comprises two hard plastic strips 41, the two plastic strips 41 are connected through a first flexible strip 42, and one end of each plastic strip 41, which is far away from the first flexible strip 42, is connected with a second flexible strip 43; the flap 4 may be made of medical grade polypropylene plastic. The first flexible strip 42 and the second flexible strip 43 are both made of silica gel, and the two plastic strips 41 are bent at the first flexible strip 42.

The middle pipe 2 is a hard plastic pipe communicated with one end of the rear section 12 of the head pipe 1, an insertion pipe 7 and a flexible retainer ring 5 are sleeved outside the middle pipe 2, a plastic nut 8 is installed at one end, exposed out of the insertion pipe 7, of the middle pipe 2, and second flexible strips 43 at two ends of each folded plate 4 are fixedly connected with one end of the transition section 13 of the head pipe 1 and one end of the insertion pipe 7 respectively; the collar 5 is fixedly connected to the end of the cannula 7 remote from the second flexible strip 43. Wherein the tail pipe 3 is a hose, and the tail pipe 3 is communicated with a drainage bottle or a drainage bag.

The using method of the invention comprises the following steps: during the use, at first insert head pipe 1 in the abdominal cavity by the abdominal cavity wall incision, let retaining ring 5 support and lean on the belly, then pull tail pipe 3 to make each folded plate 4 buckle, and then each folded plate 4 after buckling forms a separation structure in the abdominal cavity, then with nut 8 spiral on well pipe 2, cooperate with outside retaining ring 5 and press from both sides tightly in stomach wall 9 both sides, in order to realize the fixed to the drainage tube.
