Description
Technical field
The utility model relates to medical instrument sealing device technical fields, seal haemostatic valve more particularly to a kind of Y type.
Background technique
Interventional medicine technology is got up from the Later development seventies, with the development of image technology, it is often necessary to pass through
Percutaneous puncture or by the original channel of human body, special conduit or instrument are inserted send to affected site carry out diagnosis radiography, treatment,
Tissue sampling, bacteriology, cytology research, biochemical analysis treatment etc., in this surgical procedure, in order to reduce to human body group
The damage knitted reduces loss of blood, reduces operation complicated process, often using catheter sheath and other conveying devices, exchange
Device etc..These instruments are generally realized using certain sealing device, in order to effectively reduce loss of blood since it has one
Haemostatic valve, therefore blood will not be flowed outwardly from sheath, such as catheter sheath.Sheath is first inserted into blood vessel at the time of surgery, by this instrument, then
Diagnosis or therapeutic device used in operation enter blood vessel by sheath.Therefore, it can be effectively reduced using sheath to blood vessel
Damage, prevent loss of blood.Conduit and related equipment can also be very easy to enter affected site, so as to shorten entire operation
Time, mitigate patient pain, improve operation effect.Requirement to this haemostatic valve mainly has a following two points, and first, it instrument or leads
Pipe is inserted into sheath or extraction, can be carried out effective sealing.
The haemostatic valve or sealing device of existing sheath or other instruments, airtight performance shortcoming, so that haemostatic effect is bad.
Utility model content
Based on this, it is necessary to aiming at the problem that haemostatic valve or sealing device airtight performance are short of, provide a kind of Y type sealing
Haemostatic valve.
A kind of Y type sealing haemostatic valve, including locking nut, silica gel pad, Y-piece part, connector cover, short core connector, sealing
Circle and nipple, one end of the Y-piece part are arranged with locking nut, set between the locking nut and the Y-piece part
It is equipped with silica gel pad, the corresponding one end of the Y-piece part is threadedly coupled with the nipple, and the short core fitting sleeve is set to
In the nipple, the connector cover is covered on the short core connector, sets between the short core connector and the nipple
It is equipped with sealing ring.
Above-mentioned Y type seals haemostatic valve, is provided with sealing ring between short core connector and nipple, it is ensured that good between the two
Sealing performance；Silica gel pad is provided between locking nut and Y-piece part, it is ensured that sealing performance between the two.The Y type is close
Sealing blood valve arrangement is simple, the favorable sealing property at both ends, and haemostatic effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one of embodiment.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
As shown in Figure 1, a kind of Y type seals haemostatic valve, including locking nut 1, silica gel pad 2, Y-piece part 3, connector cover 4,
Short core connector 5, sealing ring 6 and nipple 7, one end of the Y-piece part 3 are arranged with locking nut 1, the locking nut 1
Silica gel pad 2, the corresponding one end of the Y-piece part 3 and 7 screw thread of nipple are provided between the Y-piece part 3
Connection, the short core connector 5 are sheathed in the nipple 7, and the connector cover 4 is covered on the short core connector 5, described short
Sealing ring 6 is provided between core connector 5 and the nipple 7.For example, Y-piece part 3 has Y type channel, branch pipe and straight line
The angled upward inclination in channel, for connecting pressure monitoring devices or other injection channels.One end of beeline channel connects
Connect pressing piece.
Above-mentioned Y type seals haemostatic valve, is provided with sealing ring 6 between short core connector 5 and nipple 7, it is ensured that between the two
Good sealing performance；Silica gel pad 2 is provided between locking nut 1 and Y-piece part 3, it is ensured that sealing performance between the two.
Y type sealing hemostasis valve arrangement is simple, the favorable sealing property at both ends, and haemostatic effect is good.
Locking nut 1 has link slot 11 in one of the embodiments, is provided with a sealing ring 8 in link slot 11, increases
It is arranged the sealing performance of pressing piece by force.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
