Abstract
The utility model relates to a measuring device for measuring the anastomotic bursting pressure of the blood vessel, belonging to the technical field of the medical equipment, which comprises a pressure gauge (1), a three way duct (3), a pressure injector (4) and a measuring duct (5), wherein, the pressure gauge, the pressure injector and the measuring duct are connected with the three orifices of the three way duct through a plurality of connecting ducts (2) respectively. When in measurement, the blood vessel at one side of the anastomotic is clamped via a hemostat, then the measuring duct of the utility model is inserted in the blood vessel at the other side of the anastomotic and is fixed; when the liquid in the pressure injector is injected in the blood vessel and the connecting duct is connected with the pressure gauge simultaneously, the value on the pressure gauge shows the pressure borne by the blood vessel anastomotic, the pressure of the anastomotic leakage or the anastomotic burst is the bursting pressure. The utility model has the advantages of simple operation, accurate pressure measurement, and provision of reliable basis for the choice of the blood vessel anastomotic proposal.
Description
Technical field: this utility model relates to technical field of medical instruments, is a kind of vascular anastomosis burst pressure checkout gear that is used for detecting the maximum pressure that vascular anastomosis can bear.
Background technology: all kinds of clinically at present medium and small vascular anastomosiss are increasing, the main method of coincideing is that traditional suture coincide, though this method is feasible technically, but time-consuming, effort, intraoperative hemorrhage are more, the patient need be through the training of long period, topmost problem is that middle neointimal hyperplasia restenosis at a specified future date finally causes operative failure owing to suture needle and suture cause the recent thrombosis of anastomotic stoma to the damage of vascular anastomosis.So cardiovascular surgery doctor and reconstructive surgery doctor are seeking to operate the medium and small vascular anastomosis scheme more simple and direct, that curative effect is more certain always, such as utilizing blood vessel anastomat to coincide, use the no suture vascular anastomosis that biogum is bonding, use laser to carry out, and the degradable biological lasso coincide and oversleeve type coincide or the like.Using one of feasibility condition that various schemes carry out medium and small vascular anastomosis is that the maximum pressure that anastomotic stoma can bear is the essential the highest systolic pressure that surpasses human body artery of vascular anastomosis burst pressure, even otherwise coincide successfully, vascular anastomosis breaks easily when arterial pressure increases, and causes severe complications such as massive hemorrhage even death.So every kind of vascular anastomosis scheme must be measured its anastomotic stoma burst pressure in the experiment in vitro stage.Yet do not see relevant vascular anastomosis burst pressure checkout gear or relevant report so far as yet.
Summary of the invention: this utility model provides a kind of vascular anastomosis burst pressure checkout gear for the medium and small vascular anastomosis of the whole bag of tricks, and this device comprises tee T, Pressure gauge, pressure injector and detector tube four parts.For ease of describing, introduce description of drawings earlier.
Description of drawings: Fig. 1 is a perspective view of the present utility model.
Now by reference to the accompanying drawings the utility model is described in detail.
This utility model comprises Pressure gauge 1, tee T 3, pressure injector 4 and detector tube 5 four parts, and Pressure gauge 1, pressure injector 4 and detector tube 5 link to each other with three mouths of pipe of tee T 3 by connection tube 2 respectively.During detection, the tee T switch that will connect Pressure gauge 1 earlier is located at the position of cutting out, liquid in the pressure injector 4 is injected in the detector tube 5 to get rid of bubble, then detector tube 5 is inserted the blood vessel of anastomotic stoma one side and fixes it, the insert division is from the about 2-3cm of anastomotic stoma, then close apart from anastomotic stoma opposite side 2-3cm place with the hemostasis clamp, this moment, three mouths of tee T were open-minded simultaneously, liquid in the pressure injector 4 is pressed into blood vessel by detector tube 5, be pressed into the connection tube 2 that links to each other with Pressure gauge simultaneously, liquid compression gas in the connection tube is transmitted to Pressure gauge with pressure, reading on the Pressure gauge has reflected endovascular pressure, that is has reflected the pressure that vascular anastomosis bore.The record anastomotic stoma is leaked or the pressure when breaking, and is the burst pressure of this vascular anastomosis.Usually vascular anastomosis should be able to bear 280mmHg pressure, and the scheme of coincideing could be successful, thereby Pressure gauge should be able to be surveyed the above pressure of 280mmHg.This device is usually with physiologic saline for substitute blood, and simple to operate, piezometry is accurate, by the mensuration of vascular anastomosis burst pressure various vascular anastomosis schemes is carried out preliminary screening, thereby provides reliable foundation for the vascular anastomosis scheme determination.
The specific embodiment:
Embodiment 1
The Pressure gauge that this device is selected for use is the product of Shanghai Medical Equipment Factory, model is a Jade Hare board, and the pressure measurement scope is 300mmHg to the maximum, and tee T is capital, a Hangzhou cool medical apparatus and instruments company limited product, specification is 2.6 * 100, pressure injector is a Medtronic company product, and specification is 20ml, and detector tube is selected glass tubing for use, length is 8cm, external diameter is 2.0mm, and connection tube is selected blood line for use, and external diameter is 2.0mm.The blood line length that connects Pressure gauge 1 and tee T 3 is 80cm, and making has enough air in the conduit, be pressed into Pressure gauge to guarantee liquid that can not.
Claims (1)
1, a kind of vascular anastomosis burst pressure checkout gear, it is characterized in that comprising Pressure gauge (1), tee T (3), pressure injector (4) and detector tube (5) four parts, Pressure gauge, pressure injector and detector tube link to each other with three mouths of pipe of tee T by connection tube (2) respectively.
