Problems solved by technology

[0002] At present, most of the puncture capsules used in medical teaching are made of silica gel, which is not resistant to puncture. After the same part is punctured continuously, generally 5-6 times, fluid leakage will occur at the eye of the puncture needle, and the service life of the puncture capsule is very low. attrition rate

Embodiment Construction

[0014] In conjunction with the accompanying drawings, the following descriptions are made:

[0015] The surface of the leak-proof puncture bag is grid-like, and there are three layers of silica gel 1 downwards. The three layers of silica gel are connected at the latitude and longitude of the grid, and the three layers of silica gel 1 outside the latitude and longitude are layered and non-adhesive. , forming the sac 2 .

[0016] The preparation method of the leak-proof puncture capsule:

[0017] Step 1. Make a mold for the water bladder, using a resin mold with a grid-like bottom;

[0018] Step 2. Take the silica gel and pour it into the water bag mold;

[0019] Step 3. After the silicone gel is cured, apply Vaseline evenly in the grid;

[0020] Step 4. Take the silica gel for the second time and pour it into the water bag mold;

[0021] Step 5. After the silicone is cured, apply Vaseline evenly on the grid for the second time;

[0022] Step 6. Take the silicone for the th...

Abstract

The invention discloses a weeping-proof puncture sac and a preparation method thereof, and relates to the field of medical teaching. The surface of the weeping-proof puncture sac is shaped like a lattice; three silica gel layers are arranged under the surface; the parts, at the warp and weft parts of the lattice, of the three silica gel layers are connected; a plurality of small sacs are formed at the parts, between the warp and weft parts of the lattice, of the three silica gel layers. According to a hydraulic pressure principle in the weeping-proof puncture sac, liquid cannot leaks from a needle hole in the part punctured fifty times by a needle. The weeping-proof puncture sac is more durable than a conventional puncture skin; the utilization rate is increased, the service life is prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of medical teaching, in particular to a puncture capsule used in thoracic puncture and abdominal puncture in a medical model and a preparation method thereof. Background technique [0002] At present, most of the puncture capsules used in medical teaching are made of silica gel, which is not resistant to puncture. After the same part is punctured continuously, generally 5-6 times, fluid leakage will occur at the eye of the puncture needle, and the service life of the puncture capsule is very low. loss rate. Contents of the invention [0003] The object of the present invention is to provide a leak-proof puncture capsule and a preparation method thereof, so as to solve the problems existing in the prior art, improve the puncture times of the puncture capsule, and prevent leakage. [0004] The technical scheme adopted in the present invention: a leak-proof puncture bag, which is characterized in that the surfa...
